In this chapter, the somatic symptom disturbances and the dissociative disorders will be discussed. In somatic symptom disorders , people have physical complaints, without an organic cause. Often the pain comes through painful emotions, thoughts or memories. In dissociative disorders , people develop several independent personalities, as a result of which they suffer from memory loss. This is because some personalities do not communicate with each other, as it were.
Somatic symptom disorders symptom disturbances
The problem with somatic is that it is difficult to determine whether the symptoms have an organic or psychological cause. Often people’s symptoms do not correspond to a physiological process associated with these symptoms. If this is the case, it is assumed that psychological factors are of influence. Another possibility is that people do have a physical illness, but that they still must be discovered or simply can not be found.
The people who have this disorder really feel the pain. It is not that they can influence or control their symptoms.
5 types of somatic symptom disorders are distinguished:
Somatic symptom disorder and Illness Anxiety Disorder
Someone with a somatic symptom disorder has one or more physical symptoms that he or she worries about, and the person spends a lot of time thinking about these symptoms and looking for medical care. It can be pain symptoms, neurological symptoms, gastrointestinal symptoms or symptoms that affect any part of the body. People with somatic symptom disorder have concerns about their health that are excessive given their current physical health. The concerns also continue to exist when they have evidence that they are healthy and interfere with their daily functioning. When they experience a certain symptom, they immediately think the worst, for example that they have cancer.
Illness anxiety disorder is very similar to somatic symptom disorder. The primary distinction in the DSM-V between these two disorders is that people with a somatic symptom disorder actually seek help while people with illness anxiety disorder are afraid that they will get a serious illness, but they do not always experience serious physical symptoms. . When they experience physical symptoms, these people are very concerned, and seek medical help before.
People with somatic symptom disorder or illness anxiety disorder often experience periods of anxiety and depression. They can express their stress in physical symptoms or mask the stress with alcohol abuse or antisocial behavior. Their symptoms and health concerns become their identity. When they are anxious or depressed, they report more physical complaints and then worry when they are not anxious or depressed.
Cognitive factors play a major role in somatic symptom disorder and illness anxiety disorder. People with these disorders have convicted dysfunctional about diseases. They assume that serious illnesses are common, and misinterpret physical changes as a sign of worry. The disorder can also be genetically determined. In addition, children of parents who catalyse their somatic symptoms can adopt the thinking style and health behaviours of their parents.
Somatic symptom disorder and illness anxiety disorder can be part of a posttraumatic stress disorder experienced by someone who has survived a severe stressor.
It is difficult to convince people with these disorders that they need psychological treatment. Psychodynamic therapies focus on providing insight into the connections between emotions and physical symptoms by helping people regain events and memories that may have triggered their physical symptoms. Behavioral therapies try to discover the empowered individuals who receive individuals for their symptoms and health complaints, and to eliminate these reinforcements and to increase positive rewards for healthy behavior. Cognitive therapies help people to correctly interpret their physical symptoms and avoid catastrophizing. Antidepressants can also reduce somatic symptoms.
Conversion disorder (functional neurological disorder)disorder
People with a conversion can suddenly no longer use certain parts of their body, often after a traumatic experience or event. For example, people are suddenly paralyzed or blind. It also happens that people do not even worry about their loss. This is called la belle indifference.
Sigmund Freud studied people with glove anaesthesia, where people lose the feeling in a hand, as if a glove had affected the feeling in that hand. He found that people got the feeling back in their hand when they were under hypnosis and had to think back on the painful feelings or thoughts. Freud thought that conversion disorders were the result of moving suppressed psychic energy to physical symptoms. According to him, the symptoms were symbols of what had been oppressed.
People with a conversion disorder are easy to hypnotize. According to researchers, this can indicate that people with this disorder spontaneously hypnotize themselves in response to extreme stress.
Conversion symptoms were very common during the two world wars. Soldiers were spontaneously blinded or paralyzed, so as not to have to go back to the front. The disorder can also occur in children. Usually their symptoms resemble the symptoms of someone who is close to them and who has a real disease. This happens mainly in children who have been sexually abused. They can imitate someone’s symptoms. For example, if a role model for the child can no longer move his arm, the child can not do that anymore. Conversion disorder is very rare. Nowadays it is thought that many cases where this diagnosis was made earlier, had a physical cause. The techniques used to be simply not good enough to recognize the real cause.
The name ‘conversion disorder’ assumes that psychological stress, often over a traumatic event, is ‘converted’ to a physical symptom. Patients and physicians often disagree with this assumption, and in the DSM-V this disorder is labelled as ‘functional neurological symptom disorder’.
Psychoanalytic treatment of this disorder is about understanding the painful emotions that are the cause of the disorder. Behaviouristic treatments focus on reducing anxiety around the trauma, thereby resolving the disorder. Often people with a conversion disorder are difficult to treat because they themselves do not think there are psychological problems.
A person with a factitious disorder deliberately acts as if he or she has a disease to receive medical attention. This is also called Munchhausen’s syndrome . A factitious disorder is not the same as malingering, where people pretend they have a symptom or disorder to prevent an undesirable situation or to get something, such as payment by the insurance. The difference between factitious disorders and malingering is therefore mainly the motivation for it.
Factitious disorder imposed on another (formerly factitious disorder by proxy) means that someone pretends that another person has a disease, for example with a child, pet or older adult. For example, parents do whether their child has a disease, or they even create a disease with their children, to get attention for themselves.
Somatization disorder and pain disorders
Someone with somatization disorder usually has a long history of complaints about physical symptoms, while no doctor can say what exactly is going on with that person. People with somatization disorder usually have pain in many areas of the body. To get the diagnosis of somatization disorder, the person must have pain symptoms in at least 4 areas of the body, including two gastrointestinal problems, one sexual symptom and one neurological symptom.
It may even be that people lose a function of the body, just as with the conversion disorder.
The symptoms of the imagined illness are often vague, dramatic or exaggerated. This exaggeration takes place to be treated anyway, even though that treatment is often not necessary.
The somatization disorder usually occurs more often within one family. It is not clear if there is a genetic cause. It may very well be that children see the somatising parent as a role model. Parents with this disorder also often ignore their children, which teaches the children to pay attention by feeling sick.
People with a pain disorder complain only about chronic pain. Pain disorder is very similar to somatization disorder, with the difference that in the pain disorder the four previously mentioned symptoms do not have to occur.
Often people with somatisation disorders and pain disorders suffer from anxiety and depression. These disorders are more common in women than in men, and in cultures where it is less accepted to have negative emotions. This may also be because men are more inclined to conceal the symptoms through alcohol abuse or antisocial behavior.
A cognitive theory states that people who have this disorder are more susceptible to pain, pay more attention to what they feel in their body and that they tend to make an elephant out of a mosquito. The interpretation of the symptoms is wrong and the pain is often exaggerated to get more attention from family and doctors. Through this way of thinking, these people express their feelings in an exaggerated way, giving them more attention from doctors and family members. There are also indications that having PTSD has an influence on the occurrence of somatisation disorder.
Many people with a somatization disorder have a history of major depression, anxiety disorder, drugs or a personality disorder.
This disorder is passed on to women in families. Men with a somatization disorder more often have problems with alcohol abuse and antisocial behavior. In families with sebum disorder, women often have depression or anxiety disorder and men with a drinking problem.
Parents with a somatization disorder often neglect their children. As a result, they teach their children that they only get attention when they are ill and therefore the children have an increased chance of getting the disorder themselves.
It is not easy to convince these people that they have a psychological disorder because they feel pain. However, if they finally cooperate with a treatment, the outlook is good. Psychodynamic theories focus on giving insight into the relationship between emotional causes and the pain they feel. They do this by recalling the experience that caused the pain in the memory. Cognitive therapies teach patients to properly assess their physical symptoms so that they are less concerned about their illness. Behavioral therapy looks at the positive reinforcers that people get through the disorder. This mainly concerns attention. These reinforcers are eliminated and positive reinforcers are created for healthy behavior.
Antidepressants also work for people with this disorder, but not as well as therapy.
Hypochondria and somatization disorder are not very different. The difference between these two is that people with somatisation disorder feel pain and that people with hypochondria are only afraid that they have a disease and do not always have physical symptoms. Once people with hypochondria feel a physical complaint, they immediately go to the doctor, while people with a somatization disorder wait longer to see how the symptoms develop. People with hypochondria often suffer from chronic depression or anxiety and often have family with the same disorders. Their fears about their health usually arise from a general sense of stress.
Cognitive therapy focuses on removing the misinterpretation of a physical feeling.
People with disturbed body experience (body dysmorphic disorder) feel that they have a body part that is completely deformed. There are about as many women as men with this disorder, only the focus of the disorder differs. Women are often concerned about their breasts, legs, hips and weight. Men are often worried or have a small physique, genitalia and lack of body hair.
People with this disorder spend hours trying to cover their ‘deformed’ body parts and often use plastic surgery to correct their problem. People with this disorder are often withdrawn because they are ashamed when other people see their deformity. This disorder is somewhat reminiscent of OCD, because it must be made obsessive that the ‘bad’ body part is covered over.
Psychoanalytic therapy is aimed at providing insight into the backgrounds of the concerns about the body part. Cognitive behavioral therapies are aimed at reducing anxiety about a certain part of the body, by changing negative thoughts about it and by desensitization. It appears that SSRIs can also help treat body dysmorphic disorder, which also suggests that this disorder may be a form of obsessive-compulsive disorder (SSRIs are also used as treatment in this disorder).
Dissociation is a process whereby parts of a person’s memory, identity or consciousness are separated from each other. Many see it as split ideas of consciousness that are accessible through dreams and hypnosis. According to Hilgard, there are two forms of consciousness: an active and a receptive mode. The active mode-active mode consists of consciously planning and taking actions. The receptive mode consists of the unconscious processing of information, as if there were ‘hidden observers’ . In most people these two different states of being merge into each other without problems, but in people with a dissociative disorder that is a big problem.
Dissociative identity disorder (DID)
Dissociative identity disorder (DID) or multiple personality disorder is a highly controversial disorder. People with this disorder have multiple personalities, sometimes more than twelve. Each of these personalities has a different character. They regularly take over the body from the ‘hostess’ or ‘host’. Each character has its own behavior, way of talking, gestures and the like. Often the different personalities, or alters, have different ages and genders. DID is much more common in women than in men, although there are no gender differences in children. Men with DID are often more aggressive than women.
In this disorder there are different personalities with specific qualities, called ‘alters’. There are different types of alters:
It may be that the host or hostess is not aware of these alters and therefore suffers from a kind of amnesia (memory loss). Sometimes the alters are aware of each other and thus information goes from one personality to another.
People often come to the therapist because of self-damaging behavior caused by the persecutor personality. They then attempted suicide or caused serious damage to their bodies.
Children can also get this disorder. The symptoms in children are different than in adults. Children often have very many emotional problems. They often suffer from symptoms that resemble the symptoms of PTSD. Children with DID often also suffer from voices in their heads (just like adults).
For 1980 the diagnosis DID was never given, and after 1980 very often. There can be various causes for this. Around 1980, this disorder was included in the DSM-III, as a result of which people were more often diagnosed with the disorder. Furthermore, in the same version, the criteria for schizophrenia were adapted so that people who used to be called schizophrenic could now receive a diagnosis for a multiple personality disorder.
It often happens that people have already received several other diagnoses before they were diagnosed with DID. Sometimes this is because DID often goes along with other disorders, such as depression, anxiety disorders (mostly PTSD) and substance abuse. It is also often associated with an eating disorder. Most people with DID also have a personality disorder. Some of the earlier diagnoses may also have been misdiagnoses of the dissociative symptoms. When people with DID say they hear voices in their heads, for example, they often get the diagnosis schizophrenia. There are a few major changes in the diagnostic criteria for DID in the DSM-V. The DSM-V has added the words ‘or an experience of possession’ to criterion A in order to make the criteria more applicable for various cultural groups. Many features of DID can be influenced by someone’s cultural background. Another change in the DSM-V is that the transition in identity does not have to be directly observed by others, but reporting by the person himself (self-report) is sufficient (criterion A). A final change is that amnesia can also occur in everyday events, and not only in traumatic experiences (criterion B).
Many scientists see DID as a result of coping strategies used in severe trauma, for example, physical or sexual abuse. Most people with DID have been sexually abused as children and have shifted this experience to a personality. This can happen because they relive it as an outsider in dreams. The abuse is often done chronically by parents or family.
In such a case, personalities are often developed that help to deal with the traumatic experience. These personalities then provide security and safety. People with DID are easy to hypnotize, which may mean that they hypnotize themselves to dissociate and escape their traumas.
DID is usually more common in certain families. It could be that the possibility to dissociate as a defence mechanism is inherited to a certain extent.
The goal of treating someone with DID is to ensure that all different personalities are integrated into a single personality. This is done by looking at the different roles of the alters, and having each alter separately process the trauma. There is also negotiation between the different personalities to bring the person back into a whole.
Sometimes antidepressants and other medications are used to help the therapy. Often a treatment of someone with DID is successful, especially if the treatment starts soon after the onset of the trauma.
A person with a dissociative fugue can suddenly move to another city and start a new life without being reminded that he has ever had a different life. The person can behave very normal in his new life, and it is crazy that he no longer remembers his past. He may suddenly return to his old life, where he continues as if he had never been away.
Such a fugue can occur once, but also more often and can take days or even years. It happens that a fugue arises from a traumatic experience, but it is more often the case that people experience a fugue when they are exposed to chronic stress. People are often depressed before the fugue starts. Fugues are more common in people who have previously had a form of amnesia (memory loss). Very little is known about this disorder because it is very rare.
In the disorders discussed above, people have amnesia (memory loss) for certain parts of their personality or past. People with dissociative amnesia have periods of amnesia, where they lose parts of, or even their entire identity, but do not assume a new identity. People with this form of amnesia are generally aware that they do not know a great deal anymore. They have a dissociative memory loss.
There is a difference between organic and psychogenic amnesia. Organic amnesia is amnesia caused by brain damage caused by, for example, a disease, the use of drugs or an accident. In an organic cause, there is usually anterograde amnesia , which means that no new information can be stored. Psychogenic amnesia has a psychological cause. Anterograde amnesia almost never has a psychological cause. Especially retrograde amnesia (not being able to retrieve old information) occurs with this form. Another difference is usually that people with psychogenic amnesia have forgotten personal information, but still know general information, and that people with organic amnesia often have forgotten both types of information.
Dissociative amnesia is a form of psychogenic, retrograde amnesia. This form of amnesia often occurs after traumatic events. Psychogenic amnesia is often the result of defence systems activating and going against stress towers or against radical memories.
Sometimes people forget a little information, for example what happened before an accident, but they can also forget large amounts of information. You can also lose your memory due to alcohol poisoning, although this is often only the case for the things that happened during your alcohol poisoning. People who are long-term alcohol addicts can get a general form of retrograde amnesia, namely Korsakoff's syndrome. Here they can no longer remember personal information.
It may also be that amnesia arises because a person was in a very high state of arousal during a certain event, so the information is not properly coded in the brain.
Another explanation is that memories of an event are sometimes associated with very painful experiences. Because people do not want to evoke the painful experiences, they cannot remember anything. A complication in the diagnosis of amnesia is that amnesia is often used as a defence argument in court cases, and it is difficult to determine whether there really is amnesia, or whether the suspect is trying to get a lighter punishment.
A subtype of dissociative amnesia is a dissociative fugue. Someone with a dissociative fugue can suddenly move to another city and start a new life without being reminded that he has ever had a different life. The person can behave very normal in his new life, and it is crazy that he no longer remembers his past. He may suddenly return to his old life, where he continues as if he had never been away.
Such a fugue can occur once, but also more often and can take days or even years. It happens that a fugue arises from a traumatic experience, but it is more often the case that people experience a fugue when they are exposed to chronic stress. People are often depressed before the fugue starts. Fugues are more common in people who have previously had a form of amnesia (memory loss). Very little is known about this disorder because it is very rare.
/ derealization Depersonalization/ derealization disorder is a condition where people often feel that they are disconnected from their thoughts and their bodies. It seems as if they are observing themselves from outside. People with depersonalization disorder regularly feel that they are not mentally or physically connected to their bodies. You only get the diagnosis for this disorder if this experience occurs regularly and if it limits your functioning in daily life. This type of experience is more common in people, but not everyone gets a diagnosis, if it does not limit their lives. The course is provoked by periods of insomnia and drug use. Half of the adults indicate that they have had a brief episode of depersonalization or derealisation, often after a significant stressor.
Abnormal psychology, frequently called psychopathology, is the study of people suffering from mental, emotional and often physical pain. Although people with psychopathological problems can have unusual experiences, most of the time these experiences are same in nature to other people's experiences but taken to an extreme degree (e.g. sadness turning into depression).
Some behaviours that seem abnormal to us are normal in other cultures or situations. When we determine whether something is normal, we have to look at the context or circumstances in which the behavior occurs. In addition to context, there are a number of criteria that must be taken into account when determining whether certain behavior is abnormal.
Cultural relativism theory states that there are no universal standards or rules to judge a behavior as abnormal. Instead, behavior can only be abnormal according to the prevailing cultural norms. Therefore, definitions of abnormality differ between cultures.
Opponents of cultural relativism believe that it can be dangerous if cultural norms dictate what is normal and abnormal. For example, throughout history, different societies have labelled certain individuals and groups as abnormal to provide justification for controlling those groups. Think of what Hitler did to the Jews. Also, such abuse often took place when slavery was legal. For example, slaves who tried to escape were diagnosed with drapetomania, a disease that caused them to desire freedom.
Gender also affects whether something is labelled as abnormal. For example, men who show sadness or fear, or who choose to stay at home with children while their wife works, are often seen as abnormal. Women who are aggressive or who do not want children are also viewed as abnormal. On the other hand, aggression in men and chronic anxiety in women are seen as normal, because these behaviours are in line with societal expectations based on sex.
In any case, it is clear that culture and gender influence the expression of abnormal behavior and the way such behavior is viewed. Furthermore, culture and gender can have an impact on determining which types of treatment for abnormal behaviours are acceptable.
Another approach of assessing abnormality is to think of how unusual the behaviour is. Behavior that is deviant or unusual is seen as abnormal, while typical or standard behavior is considered normal. In a sense, such attitude is linked to the relativistic criterion, because the unusual nature of behavior is partly dependent on cultural norms of that behavior.
The relativistic criterion has some shortcomings. For example, how unusual a behavior has to be to call it abnormal? Is a behavior abnormal if less than 10% of the population displays it, or if less than 1% displays it? In addition, plenty of rare behaviours are positive for the individual and society, making it strange to call such behaviours abnormal. People who exhibit such rare but positive behaviours are often called eccentric.
According to the distress criterion a behavior can be seen as abnormal if it causes a feeling of distress

Based on this framework, questions can be asked about a particular phenomenon and information collected and interpreted about this phenomenon. A therapy is a treatment, often based on a theory about a disorder, that deals with the factors that cause the disorder according to the theory.
There are different approaches for explaining psychological complaints. For example, when it comes to anxiety, the biological approach symptoms suggests that the symptoms can be caused by a genetic predisposition to anxiety. The psychological approach seeks the explanation in a person's beliefs, life experience and relationships. The sociocultural approach looks at the cultural values or social environment of a person. These different approaches are often seen as incompatible. People seek either a biological explanation or a socio-cultural explanation. This is also called the nature-nurture debate : is the explanation in someone's nature, or in education (or environment).
Although it is tempting to look for a single explanation, theoreticians often start from the biopsychosocial approach, which recognizes that it is often a combination of biological, psychological and socio-cultural factors. Vulnerability to a disorder can also lie with each of these factors and therefore does not always have to be genetic. Only vulnerability is not enough to develop a disorder, only when another trigger occurs (e.g. stress), the disorder could really develop.
Treatments have also been developed for each approach. The biological approach mainly requires medication, from the psychological and sociocultural approach it usually concerns psychotherapy. Both types of treatment have proved effective and are often used together, in an integrated approach.
The famous story of Phineas Gage describes how this man, one day through an accident at work, received a thick iron rod through his skull and brain. Miraculously, he survived this accident and he recovered completely physically. His personality, however, had changed completely: from a responsible, friendly and intelligent man, he had suddenly changed into a capricious person who had no respect for social norms. His sense of responsibility was completely gone.
Later research showed that Gage mainly suffered damage to the frontal lobe. People who have damage to this part of the brain often have trouble taking rational decisions in social situations and have trouble processing information about emotions. They can still solve logic and abstract problems, just like Gage still could.
Brain dysfunction is only one of the three possible biological causes of abnormality. The other two are biochemical imbalances and genetic abnormalities. These three causes can also influence each other. For example, brain dysfunction can be the result of genetic factors and this can cause biochemical imbalance.
The brain can be subdivided into three main areas: the hindbrain, midbrain and forebrain. The back brains contain the medulla (controls breathing and reflexes), punch (important for attention and timing of sleep), reticular formation (controls arousal and attention to stimuli) and cerebellum (is involved

There are modern methods for diagnosing. Assessment techniques must be valid and reliable. In addition, they must be standardized.
To say that a test is valid: the test must actually measure that for which it was designed. The validity for testing psychological disorders is not very large, because there are no good objective methods for determining these.
There are different types of validity:
The reliability is the certainty that the outcome of the measurement remains the same. Different types of reliability:
To prove validity and reliability, you can standardize the data collected of a test, so that there is no variation between tests in how this is done.
A lot of information for an assessment comes from an interview, which often includes an investigation into the mental status.
There are five types of information:
Clinicians increasingly use structured interviews: a series of questions about the symptoms.
In order to quickly determine what the symptoms are, a symptom questionnaire can be filled out. A frequently used questionnaire is the Beck Depression Inventory (BDI): here you have to judge for yourself which description best suits how you felt during the past
.....read moreDue to evolution, humans and animals have an automatic reaction to danger: the fight or flight response (fight or flight). The psychological changes that arise during this response are due to the activation of two systems: the autonomic nervous system and the adrenal cortical system.
The hypothalamus activates the sympathetic part of the autonomic nervous system, which prepares to fight or flight by releasing energy. The hypothalamus also activates the adrenal cortical system by releasing CRF (corticotrophin-releasing hormone), which releases the adrenocorticotropic hormone (ACTH). This hormone causes the cortisol level to rise. Cortisol in the blood and urine is an indicator of stress. We then experience the emotions that come with danger, after which we either confront the danger (fight) or run from it(flight).
People with anxiety disorders follow the same pattern, but with them there is no actual objective danger but rather a more subjective, psychological one.
We refer to anxiety disorder when people are continuously living with fear and normal functioning is thereby impeded. When this happens, people tend to realize the unreal nature of the disorder and suffers from it.
Fear consists of four different types of symptoms.
1. somatic symptoms: physical responses such as sweating and increased blood pressure
2. emotional symptoms: feelings of anxiety and vigilance
3. cognitive symptoms: unrealistic worries such as the feeling that something bad is going to happen
4. behavioral symptoms: such as avoidant or flight behaviours.
Posttraumatic stress disorder and acute stress disorder both occur as a result of an experience of extreme stress. For example, many people developed a stress disorder in America as a result of the 11th of September attacks. Furthermore, it is estimated that 7% of the people experience stress during their lifetime as a result of a traumatic experience.
For a diagnosis of PTSD, from all the symptoms in the DSM, at least the following four are necessary:
Many people with PTSD experience symptoms of dissociation, a process in which parts of the identity, memories or consciousness lose contact with each other. These people can be diagnosed with the subtype PTSD with prominent dissociative symptoms.
An acute stress disorder occurs in traumas that resemble PTSD, only the symptoms of acute stress disorder develop within a month. Dissociative symptoms are common in ASD: stiffening, less awareness of the environment, experiencing the world as a dream. People with ASD have an increased risk of developing PTSD.

5 types of somatic symptom disorders are distinguished:
Somatic symptom disorder and Illness Anxiety Disorder
Someone with a somatic symptom disorder has one or more physical symptoms that he or she worries about, and the person spends a lot of time thinking about these symptoms and looking for medical care. It can be pain symptoms, neurological symptoms, gastrointestinal symptoms or symptoms that affect any part of the body. People with somatic symptom disorder have concerns about their health that are excessive given their current physical health. The concerns also continue to exist when they have evidence that they are healthy and interfere with their daily functioning. When they experience a certain symptom, they immediately think the worst, for example that they have cancer.
Illness anxiety disorder is very similar to somatic symptom disorder. The primary distinction in the DSM-V between these two disorders is that people with a somatic symptom disorder actually seek help while people with illness anxiety disorder are afraid that they will get a serious illness, but they do not always experience serious physical symptoms. . When they experience physical symptoms, these people are very concerned, and seek medical help before.
People with somatic symptom disorder or illness anxiety disorder often experience periods of anxiety and depression. They can express their stress in physical symptoms or mask the stress with alcohol abuse or antisocial behavior. Their symptoms and health concerns become their identity. When they are anxious or depressed, they report more physical complaints and then worry when they are not anxious or depressed.

People with depression are completely confiscated by the disorder; depression affects the emotions, body functions, behaviours and thoughts of man.
The most important emotional symptoms in someone with a unipolar disorder are the sadness and the loss of all interest in life, which is referred to by the term anhedonia.
Many have also in people with depression body functions changed. These are changes in appetite, sleep and activity. Some people with depression have very little appetite, whereas others, on the other hand, very much.
In their behavior , many depressed people show changes in their way of moving. For example, they move very slowly in everything they do. This is called psychomotor retardation . Many people feel that they have little energy and that they are constantly tired. A small part of the depressed people feels restless. These people have opposite symptoms: psychomotor agitation, in which people feel physically agitated, can not sit still and walk around aimlessly or fidget.
The cognitive symptoms of depression are all kinds of thoughts about, for example, hopelessness, shame and suicide. In serious cases, there are also delusions and hallucinations. Delusions are thoughts that have no basis in reality. Hallucinations are observations that someone has, who are not actually there.
Depression can take different forms. Major depressive disorder is a severe depression that lasts at least two weeks. The diagnosis requires that someone feels depressed or has a loss of interest in daily activities. In addition, at least four other symptoms of depression must be present. According to the DSM-IV, there are two types of unipolar depression: major depression and dysthymic disorder. The difference between these two disorders is that a major depression is of shorter duration, but very intense. Dysthymic disorder is a chronic form of depression, which lasts for at least one year in adolescents and two years in adults. This depression can be less severe a major depressive disorder. A person must have a depressed mood and his interest in life must be lost. In addition, there must be at least four other symptoms of depression for at least two weeks, involving a disruption of daily life. There are two types of major depressions: in the first type (major depression single occurrence) there is only one single depressive episode, while in the second type (major depression periodically) there are two or more episodes with at least two consecutive months without symptoms between the episodes. The DSM-V criteria contain the observation that a normal and expected depressive response to a negative event, such as a loss, should not be diagnosed as a major depressive disorder unless other symptoms such as worthlessness, suicidality and psychomotor retardation are present.
More chronic forms
.....read moreA person suffers from psychosis if he has hallucinations and delusions and can not say with certainty whether his observations are real or not. A form of psychosis that often occurs is schizophrenia. People can sometimes think very clearly and function well, but also have moments when they can no longer take care of themselves.
Schizophrenia occurs in 1 to 2 percent of people in the United States and in 0.5 to 1 percent of all people around the world. Schizophrenia is more common in men than women and is more common in colored people than in whites. About 90% of people with schizophrenia seek help. The disorder often develops in youth or young adulthood.
Schizophrenia is a very complex disorder. A distinction is made between two categories of symptoms, the positive and the negative symptoms. The DSM-V refers to the schizophrenia spectrum, to show that there are five domains of symptoms that define psychotic disorders, and their number, severity and duration distinguish psychotic disorders from each other.
Positive symptoms
Positive symptoms, or Type I symptoms, are characterized by the presence of delusions, hallucinations, disorganized speech and thoughts and disorganized or catatonic behavior. These symptoms can also occur in other disorders, such as bipolar disorder, so that makes the diagnosis for schizophrenia difficult. It is also possible that the symptoms occur in people who actually have no problems. Think of people who hear voices and attribute this to their religion. There are also people who, due to the symptoms, have no control over reality: delusional disorder (delusions).
The rule is that if the positive symptoms only occur during a manic or depressive period, the diagnosis 'mood disorder with psychotic characteristics' is made. If the positive symptoms also occur outside the manic or depressive periods, the diagnosis is made schizophrenia.
Delusions are ideas that the patient thinks are true, while those ideas are very unlikely or even impossible. Many people sometimes have unlikely thoughts, but there are differences between these kinds of thoughts and delusions. When healthy people have unlikely thoughts, they are not completely unbelievable, while delusions are. People with delusions constantly think about it and seek evidence for their ideas, with which they try to convince others. In addition, people with delusions can not accept that their thoughts are not right.
There are four kinds of delusions:
Personality is the collection of characteristics that the person has or shows and that distinguishes him or her from others. It is the way we behave, think, believe and feel. These characteristics make us unique.
A personality trait is a complex pattern of behavior, thoughts and emotions that remain constant over a longer period of time, and in different situations.
The 'big five' theory states that there are five different factors of personality traits. Everyone satisfies every factor to a certain extent, and how strongly that per factor is the case determines our personality.
The big five:
Definition and diagnosis of personality disorder
A personality disorder is a long-term pattern of unadopted behavior, thoughts and feelings. Personality disorders usually begin in adolescence, or in early adulthood, and sustain a large part of life. To diagnose a personality disorder in a person under the age of eighteen, the personality pattern must be present for at least a year.
In the DSM-IV, personality disorders are on the second axis. This means that these disorders are seen differently from acute disorders. The disorders on the second axis are chronic and penetrating. The DSM-V has rejected this distinction between disorders on As-I and As-II. Personality disorders are therefore no longer on the second axis in the DSM-V. The DSM-V has divided ten personality disorders into three clusters, based on their similarities. The DSM-V admits that this system is limited, not well validated and does not explain the fact that people often have multiple personality disorders from different clusters. The three clusters of the DSM-V are as follows:
Odd-eccentric personality disorders
People with an odd-eccentric personality disorder (from cluster A) behave in ways that strongly suggest schizophrenia. Many scientists therefore believe that this disorder is a weakened version of schizophrenia, or that people with this disorder have a very high chance of developing schizophrenia. Some scientists believe that this disorder should fall under schizophrenia than under the personality disorders, precisely because it appears to be a mild version of schizophrenia.

Most individuals meet the criteria for two or more eating disorders at different times. Many people do not meet the criteria for an eating disorder, but do show behaviours and concerns that fit in an eating disorder. They are diagnosed with other specified feeding or eating disorder.
People with anorexia nervosa are hungry themselves, while they are already well under a healthy weight. They do this by not eating or eating for a long time. Although they are already very thin, they insist that they have to lose even more weight. People with anorexia refuse to maintain a healthy, normal weight. Although these people are very emaciated, they have an intense fear of weight gain or fat. They have a disturbed idea about their bodies and think they are fatter than they actually are and therefore have to lose weight.
The self-esteem of these people depends entirely on their body weight and the control over their eating behavior; they feel good when they lose weight and are guilty or worthless if they do not succeed. Due to the loss of weight, people with anorexia nervosa are often chronically fatigued. Despite this fatigue, they continue to draw up heavy training programs to lose weight.
Anorexia nervosa usually starts between 15 and 19 years. 90 to 95 percent of all cases with anorexia nervosa are women. Due to the weight loss, the menstrual cycle stops in girls and women with anorexia, this is called amenorrhea . In the DSM-V the criterion for amenorrhea has been removed from the diagnostic criteria, because many girls with anorexia nervosa still have menstrual activity. Anorexia is, in a physical sense, a dangerous disorder. Serious complications such as a very low heart rate or damage to the kidneys may be the result; 5 to 8 percent of people with anorexia will die of it.
There are two types of anorexia nervosa. People with the restricting type of anorexia nervosa refuse to eat, or eat very small amounts, to prevent them from gaining weight. Some do not eat anything for days. People with the restricting type of anorexia nervosa often have a feeling of distrust towards others and the tendency to deny their problems.
The other type is the binge / purge type of anorexia nervosa. These people have binge eating (binges) that alternate with actions to prevent weight gain (purge). This often happens through deliberate vomiting or use of laxatives. People with the binge / purge type of anorexia nervosa often have varying moods, problems with the control of their impulses, problems with alcohol and self-mutilation.
The binge / purge type of anorexia nervosa is very similar to bulimia. The difference is that people with the binge / purge type of anorexia nervosa do not have a healthy weight, while people with bulimia nervosa generally have a healthy weight or even a bit of overweight.
Just like in the DSM-IV,
