Late life and neurocognitive disorders
As we age, physiological changes are inevitable, and there may be emotional and mental changes as well.
Many of these influence social interactions.
The problems experienced in late life
Mental health is tied to the physical and social problems in a person’s life.
No other have more of these problems than the elderly.
As people age, the quality of depth of sleep declines.
Sleep apnea: a disorder in which a person stops breathing for seconds to minutes during the night. Increase with old age.
Several problems are evident in the medical treatment available during late life.
Research methods in the study of aging
Three kinds of effects:
Two major research designs
The DSM criteria are the same for older and younger adults.
The process of diagnoses must be considered with care. DSM criteria specify that a psychological disorder should not be diagnosed if the symptoms can be accounted for by a medical condition or medication side effects.
Clinicians must be extremely careful to consider the interactions between physical and psychological health.
Estimating the prevalence of psychological disorders in late life
Persons over age 65 have the lowest overall prevalence of mental disorders of all age groups.
Mot people with psychological disorders in late life are experiencing a continuation of symptoms that began earlier.
Why so low?
Methodological issues in estimating the prevalence of psychopathology
Enhanced coping abilities developed across the life course may help protect people from mental illness during late life.
Dementia
Dementia: a descriptive term for the deterioration of cognitive abilities to the point the functioning is impaired.
Difficulty remembering things is the most common symptom of dementia.
Los of control of impulses.
Delusions and hallucinations may occur.
Language disturbances.
Delirium: a state of mental confusion.
The course of dementia may be progressive, static, or remitting, depending on the cause.
DSM-5 provides parallel diagnoses like those for mild cognitive impairment as well as for dementia.
Not all people with mild cognitive symptoms develop dementia.
Prevalence of dementia is 0,4 percent. Increases with age.
DSM-5 criteria for Mild neurocognitive disorder
DSM-5 criteria for Major neurocognitive disorder
Alzheimer’s disease
In Alzheimer’s disease, the brain tissue irreversibly deteriorates, and death usually occurs within 12 years after the onset of symptoms.
The illness may begin with absentmindedness and difficulties in concentration an in memory for new material. These shortcomings may be overlooked for several years, but eventually interfere with daily living.
As the disease develops, problems with language skills and word finding intensify. Visual-spatial abilities decline, which can be manifested in disorientation and trouble copying figures.
People with the disorder are typically unaware of their cognitive problems initially.
Memory continues to deteriorate, and the person becomes increasingly disoriented and agitated.
People with Alzheimer's disease have more plaques (small, round beta-amyloid protein deposits that are outside the neurons) and neurofibrillary tangles (twisted protein filaments composed largely of the protein tau in the axons of neurons) than would be expected for the person’s age.
The beta-amyloid plaques are most densely present in the frontal cortex and they may be present for 10 to 20 years before the cognitive symptoms become noticeable.
Tangles are most densely present in the hippocampus. Over time, as the disease progresses, plaques and tangles spread trough more of the brain.
The plaques and tangles appear related to a host of brain changes over time.
At early stages, there seems to be a loss of synapses for acetylcholingeric and glutamatergic neurons. Neurons also begin to die.
As neurons die, the cerebral cortex, entorhinal cortex, and hippocampus shrink, and later the frontal, temporal, and parietal lobes shrink. As this happens, the ventricles become enlarged.
The cerebellum, spinal cord, and motor and sensory areas of the cortex are less affected.
Heritability of 79 percent in Alzheimer’s disease.
Having one E4 allele increases the risk of Alzheimer’s disease.
People with two E4 alleles show overproduction of beta-amyloid plaques, loss of neurons in the hippocampus, and low glucose metabolism in several regions of the cerebral cortex even before they develop symptoms of Alzheimer’s disease.
Lifestyle variables may play a role in Alzheimer’s.
Frontotemporal dementia
Frontotemporal dementia (FTD) is caused by a loss of neurons in frontal and temporal regions of the brain.
The neuronal deterioration of FTD occurs predominantly in the anterior temporal lobes and prefrontal cortex.
Typically begins in the mid- to late 50s, and it proceeds rapidly. Death usually occurs within 5-10 years of the diagnosis.
Memory is not severely impaired in FTD.
The diagnostic criteria for FTD include deterioration in at least three of the following areas at a level that leads to functional impairment
In early stages, significant others may notice changes in personality and judgment.
The disorder strikes emotional processes in a more profound manner than Alzheimer’s disease does. It can damage social relationships.
Particular deficits seem to emerge in the ability to regulate emotions. People with FTD may not realize they are violating social conventions.
FTD can be caused by many different molecular processes.
FTD has a strong genetic component, although there may be multiple genetic pathways involved.
Vascular dementia
Vascular dementia is diagnosed when dementia is a consequence of cerebrovascular disease.
Most commonly, the person has a series of strokes in which a clot formed, impairing circulation and causing cell death.
Risk for vascular dementia involves the same risk factors as those for cardiovascular disease in general.
Because strokes an cardiovascular disease can strike different regions of the brain, the symptoms of vascular dementia can vary a good deal.
The onset of symptoms is usually more rapid in vascular dementia than in other forms of dementia.
Vascular dementia can co-occur with Alzheimer’s disorder.
Dementia with Lewy bodies
Dementia with Lewy bodies (DLB) can be divided into two subtypes, depending on whether or not it occurs in the context of Parkinson’s disease.
The symptoms associated with this type of dementia are often hard to distinguish form the symptoms of Parkinson’s and Alzheimer’s disease.
DLB is more likely than Alzheimer’s disease to include prominent visual hallucinations and fluctuating cognitive symptoms.
People with DLB are often extremely sensitive to the physical side effects of anitpsychotic medications.
People with DLB often experience intense dreams accompanied by levels of movement and vocalizing that may make them seem as though they are ‘acting out their dreams’.
Dementias caused by disease and injury
A number of other medical conditions can produce dementia.
Both can cause dementia.
The organism that produces the ventral disease syphilis can invade the brain and cause dementia.
Dementia can also be caused by
Prevention and treatment of dementia
A few drugs may provide modest protection against cognitive decline, but the effects are slim.
There is no cure for dementia.
Most efforts at presentation of Alzheimer’s disease have failed.
Medications
No medications have been shown to address the cognitive symptoms of FTD.
Medications may help slow decline, but they do not restore memory function to previous levels.
Medical treatments are commonly used to address psychological symptoms that commonly co-occur with dementia.
Although antipsychotic medications can provide modest relief for aggressive agitation, they also increase the risk of death among elderly people with dementia.
Psychological and lifestyle treatments
Supportive psychotherapy can help families and patients deal with the effects of the disease.
Generally, the therapists allows opportunities for the person with dementia and the family to discuss the illness.
The therapists also provides accurate information about the illness, helps family members care for the person in the home, and encourages a realistic rather than a catastrophic attitude in dealing with the many specific challenges that this cognitive disorder presents.
Exercise also appears to have modest benefits in improving cognitive function.
Behavioral approaches have been shown to help compensate for memory loss and to reduce depression and disruptive behavior among people with early stages of Alzheimer’s disease.
Delirium
DSM-5 criteria for Delirium
Delirium: being off-track or deviating form the usual state. Typically described as a clouded state of consciousness.
The two most common symptoms are:
Vivid dreams and nightmares are common
Memory impairment, especially for recent events, is common
In the course of a 24-hours period, people with delirium have lucid intervals in which they become alert and coherent. They are usually worse during sleepless nights.
These daily fluctuations help distinguish delirium form other syndromes.
Perceptual disturbances are frequent in delirium.
Swings in activity and mood accompany these disordered thoughts and perceptions.
People of any age are subject to delirium, but it is more common among children and older adults.
Mortality rate for delirium is high.
Etiology of delirium
Delirium is caused by medical conditions.
Causes
Delirium usually has more than one cause.
Treatment of delirium
Complete recovery form delirium is possible if the underlying cause is treated promptly and effectively.
Beyond treating the underlying medical conditions, the most common treatment is atypical antipsychotic medication.
It usually takes 1 to 4 weeks for the condition to clear, it takes longer in older people than in younger people.

Introduction and historical overview
Introduction
Psychopathology: the field concerned with the nature, development, and treatment of mental disorders.
Continually developing and adding new findings.
Sigma: the destructive beliefs and attitudes held by a society that are ascribed to groups considered different in some manner, such as people with mental illness.
Stigma has four characteristics:
The treatment of individuals with mental disorders throughout recorded history has not generally been good, and this has contributed to their stigmatization.
Mental illness remains one of the most stigmatized of conditions in the twenty-first century.
Mental disorder is one disorder that contains several characteristics.
Four key characteristics that any comprehensive mental disorder definition ought to have:
No single characteristic can fully define the concept.
Mental disorder is usually determined based on the presence of several characteristics at one time.
Personal distress
A person’s behavior may be classified as disordered if it causes him or her great distress.
But not all mental disorders cause distress.
And not all behavior that causes distress is disordered.
Disability
Impairment in some important area of life.
Disability alone cannot be used to define mental disorder. Not all disorders involve disability.
Other characteristics that might, in some circumstances, be considered disabilities, do not fall within the domain of psychopathology.
Violation of social norms
In the realm of behaviors, social norms are widely held standards that people use consciously or intuitively to make judgments about where behaviors are situated on such scales as good-bad, right-wrong, justified-unjustified, and acceptable-unacceptable.
Behavior that violates social norms might be classified as disordered.
This is not enough for defining mental disorder. It is too broad and too narrow.
And social norms vary across cultures and ethnic groups.
Dysfunction
Harmful dysfunction. Has a value judgment and a objective component (dysfunction).
A judgment

Current paradigms in psychopathology
Introduction
Science is a human enterprise that is bound by scientists’ human limitations.
Paradigm: a conceptual framework or approach within a scientist works.
A paradigm as profound implications for how scientist operate at any given time.
Three paradigms that guide the study and treatment of psychopathology
Factors that cut across all the paradigms:
Almost all behavior is heritable to some degree.
Despite this, genes do not operate in isolation from the environment. Through the life span, the environment shapes how our genes are expressed, and our genes also shape the environment.
Nature via nurture.
Without the environment, genes could not express themselves and thus contribute to behavior.
Genes: the carriers of genetic information.
The number of genes is not important. The sequencing, or ordering, of these genes as well as their expression is what makes us unique.
What genes do matters more than the number of genes we have. Genes make proteins that in turn make the body and the brain work.
Gene expression: some proteins switch, or turn, on and off other genes.
Polygenic: several genes turning themselves on and off as they interact with a person’s environment is the essence of genetic vulnerability.
We do not inherit mental illness from our genes. We develop mental illness trough the interaction of our genes with our environment.
Heritability: the extent to which variability in a particular behavior in a population can be accounted for by genetic factors.
Shared environment factors: those things that members of a family have in common, such as parents’ marital status.
Nonshared environment (or unique environment) factors: those things believed to be important in understanding why two siblings from the same family can be so different.
Nonshared environmental experiences have much more to do with the development of mental illness than the shared experiences.
Behavior genetics
Behavior genetics: the study of the degree to which genes and environmental factors influence behavior.
Genotype: the total genetic makeup of an individual, consisting of inherited genes. The genotype cannot be observed outwardly.
Phenotype: the totality of observable behavioral characteristics.
The genotype should not be viewed as a static entity. Genetic programs are quite flexible.
The phenotype changes
Diagnosis and assessment - summary of chapter 3 of Abnormal Psychology by Kring, Davison, Neale & Johnson (12th edition)Clinical psychology
Chapter 3
Diagnosis and assessment
Introduction
Diagnosis can be the first major step in good clinical care.
Having a correct diagnosis will allow the clinician to describe base rates, causes, and treatment.
Hearing a diagnosis can help a person understand why certain symptoms are occurring.
Two concepts that play a key role in diagnosis and assessment:
Reliability
Reliability: consistency of measurement.
Validity
Validity: whether a measure measures what it is supposed to measure.
Unreliable measures will not have good validity.
Reliability does not guarantee validity.
The diagnostic system of the American psychiatric association: DSM-5
Diagnostic and Statistical Manual of Mental Disorders (DSM).
Multiaxial classification system forces the diagnostician to consider a broad range of information.
Axis:
Removal oaf the multiaxial system
The multiaxinal system developed for DSM-IV-TR is removed in DSM-5.
In place of the first three axes clinicians are simply to note psychiatric and medical diagnoses.
Organizing diagnoses by causes
DSM-5 defines diagnoses entirely on the basis of symptoms.
In the DSM-5, the chapters are reorganized to reflect patterns of comorbidity and shared etiology.
Enhanced sensitivity to the developmental nature of psychopathology

Research methods in psychopathology
Introduction
Theory: a set of propositions meant to explain a class observations.
Hypotheses: expectations about what should occur if a theory is true.
The case study
Case study: recording detailed information about one person at a time.
The case study can be used:
The correlational method
Variables are measured as they exist in nature.
Psycho-pathologist will rely on correlational methods when there are ethical reasons not to manipulate a variable.
Comparison of people with and without diagnoses can be correlational as well.
Measuring correlation
Statistical and clinical significance
A statistical correlation is unlikely to have occurred by chance.
A non-significant correlation may have occurred by chance, so it does not provide evidence for an important relationship.
A statistical finding is usually considered significant if the probability that it is a chance finding is 5 less in 100. p<0.05.
In general, as the absolute size of the correlation coefficient increases, the result is more likely to be statistically significant.
The significance is also influenced by the number of participants in the study.
Clinical significance: whether a relationship between variables is large enough to matter.
Problems of causality
Correlational method does not allow determination of cause-effect relationship.
Epidemiology: the study of the distribution of disorders in a population.
Focuses on three features of a disorder
Epidemiological studies are designed to be representative of

Mood disorders
Mood disorders involve disabling disturbances in emotion.

The cardinal symptoms of depression include profound sadness and/or an inability to experience pleasure.
Physical symptoms of depression are also common
Social withdrawal is common.
Major depressive disorder

Anxiety disorders - summary of chapter 6 of Abnormal Psychology by Kring, Davison, Neale & Johnson (12th edition)Clinical psychology
Chapter 6
Anxiety disorders
Introduction
Anxiety: apprehension over an anticipated problem (future)
Fear: a reaction to immediate danger
Both anxiety and fear can involve arousal, or sympathetic nervous system activity.
Anxiety and fear are both adaptive.
In some anxiety disorders, the fear system seems to misfire. A person experiences fear at a time when there is no danger in the environment.
Anxiety creates a U-shape curve with performance.
Anxiety disorders as a group are the most common type of psychiatric diagnosis.
Phobias are particularly common
For each anxiety disorder, several criteria must be met for a DSM-5 diagnoses to be made:
Each disorder, though, is defined by a different set of symptoms related to anxiety or fear.
Anxiety disorders:
Specific phobias
A specific phobia: a disproportionate fear caused by a specific object or situation.
The person recognizes that the fear is excessive, but still goes to great lengths to avoid the feared object or situation.
Specific phobias tend to cluster around a small number of feared objects and situations.
The DSM categorizes specific phobias according to these sources of fear.
A person with one type of specific phobia is very likely to have another type of specific phobia as well. There is high comorbidity of specific phobias.
DSM-5 criteria:
Social anxiety disorder
Social anxiety disorder: a persistent, unrealistically intense fear of social situations that might involve being scrutinized by, or even just exposed to, unfamiliar people.
The problems caused by it tend to be much more pervasive and to interfere much more with normal activities than the problems caused by other phobias.
Social anxiety disorder generally begins during adolescence. For some, though, the symptoms first emerge during childhood.

Chapter 7
Obsessive-compulsive-related and trauma-related disorders
OCD is defined by repetitive thoughts and urges (obsessions) as well as an irresistible need to engage in repetitive behaviors or mental acts (compulsions)
Body dysmorphic disorder and hoarding disorder have symptoms or repetitive thoughts and behaviors.
For all three conditions, the repetitive thoughts and behaviors are distressing, feel uncontrollable, and require a considerable amount of time.
For the person with these conditions, the thoughts and behaviors feel unstoppable.
These syndromes often co-occur.
Clinical descriptions and epidemiology of the obsessive-compulsive and related disorders
Obsessive-compulsive disorder
Obsessive-compulsive disorder (OCD) is characterized by obsessions or compulsions.
Obsessions: intrusive and recurring thoughts, images, or impulses that are persistent and uncontrollable and often appear irrational to the person experiencing them.
For people with OCD, obsessions have such force and frequency that they interfere with normal activities.
People with obsessions may also be prone to extreme doubts, procrastination, and indecision.
Compulsions: repetitive, clearly excessive behaviors or mental acts that the person feels driven to perform to reduce the anxiety caused by obsessive thoughts or to prevent some calamity from occurring.
Even though rationally understanding that there is no need for this behavior, the person feels as something dire will happen if the act is not performed.
The sheer frequency with which compulsions are repeated may be staggering.
Commonly reported compulsions:
OCD tends to begin either before age 10 or else in late adolescence/early adulthood.
Slightly more common among women than men.
The pattern of symptoms appears to be similar across cultures.
High comorbidity.

Dissociative disorders and somatic symptom- related disorders - summary of chapter 8 of Abnormal Psychology by Kring, Davison, Neale & Johnson (12th edition)Clinical psychology
Chapter 8
Dissociative disorders and somatic symptom- related disorders
Introduction
Both types of disorders are hypothesized to be associated with stressful experiences, yet symptoms do not involve direct expressions of anxiety.
Dissociative and somatic symptom-related disorders tend to be comorbid.
The DSM-5 includes three major dissociative disorders:
The dissociative disorders are all presumed to be caused by a common mechanism, dissociation. Which results in some aspect of cognition or experience being inaccessible consciously.
Dissociation and memory
Psychodynamic theory suggests that in dissociative disorder traumatic events are repressed.
In this model, memories are forgotten because they are so aversive.
Memory for emotional relevant stimuli is enhanced by stress, while memory for neutral stimuli is impaired.
Dissociative disorders involve unusual ways of responding to stress.
Extremely high levels of stress hormones could interfere with memory formation.
In the face of severe trauma, memories may be stored in such a way that they are not accessible to awareness later when the person has returned to a more normal state.
Dissociative disorders are considered an extreme outcome of this process.
Dissociative amnesia
The person with dissociative amnesia is unable to recall important personal information, usually information about some traumatic experience.
The holes in memory are too extensive to be explained by ordinary forgetfulness.
The information is not permanently lost, but it cannot be retrieved during the episode of amnesia, which may last for as short a period as several hours, or as long as several years.
The amnesia usually disappears as suddenly as it began, with complete recovery and only a small change of recurrence.
Most of the memory loss involves information about some part of a traumatic experience.
More rarely the amnesia is for entire events during a circumscribed period of distress.
During the period of amnesia, the person’s behavior is otherwise unremarkable, except that the memory loss may cause some disorientation.
In a more severe sub-type of amnesia, fugue, the memory loss is more extensive.
The person not only becomes totally amnesic but suddenly leaves home and work.
Recovery is usually complete, although it takes various amounts of time.
After recovery, people are fully able to remember the details of their life and experiences,

Schizophrenia
Schizophrenia: a disorder characterized by disturbances in thought, emotion and behavior.
>1% prevalence
Slightly more men than women.
Sometimes develops in childhood, but usually appears in late adolescence or early adulthood
people with schizophrenia typically have a number of episodes of their symptoms and less severe but still debilitating symptoms between episodes.
The range of symptoms in the diagnosis of schizophrenia is extensive, although people with schizophrenia typically have only some of these problems at any given time.
No single essential symptom must be present for a diagnosis of schizophrenia.
Researchers divided symptoms in three
DSM-5 criteria of schizophrenia
Positive symptoms
Positive symptoms comprise excesses and distortions, such as hallucinations and delusions.
For the most part, acute episodes of schizophrenia are characterized by positive symptoms.
Delusions
Delusions: beliefs contrary to reality and firmly held in spite of disconfirming evidence.
Common symptoms in schizophrenia.
Delusions take several forms including:
Delusions are also found in other diagnoses,
Hallucinations and other disturbances of perception
Hallucinations: sensory experiences in the absence of any relevant information for the environment.
More often auditory than visual.
Negative symptoms
The negative symptoms of schizophrenia consists of behavioral deficits.

Substance use disorders
Prevalence adolescents: 9,3 to 10 percent.
Addiction: a more severe substance use disorder that is characterized by having more symptoms, tolerance, and withdrawal, by using more of the substance than intended, by trying unsuccessfully to stop, by having physical or psychological problems made worse by the drug, and by experiencing problems at work or with friends.
Tolerance: indicated by either:
Withdrawal: the negative physical and psychological effects that develop when a person stops taking the substance or reduces the amount.
DSM-5 criteria for substance use disorder
Alcohol use disorder
Delirium tremens (DTs): when the level of alcohol in the blood drops suddenly.
Liver enzymes that metabolize alcohol can account to a small extent for tolerance. The central nervous system is responsible as well.
Tolerance results from changes in the number or sensitivity of GABA or glutamate receptors. Withdrawal may result because some neural pathways increase their activation to compensate for alcohol’s inhibitory effects in the brain.
Alcohol use disorder is often part of polydurg abuse.
Polydrug abuse: abusing ore than one drug at a time.
Alcohol and nicotine are cross-tolerant; nicotine can induce tolerance for the rewarding effects of alcohol and vice versa.
Consumption of both drugs may be increased to maintain their rewarding effects.
Prevalence and cost of alcohol abuse and dependence
No yet prevalence estimates.
Especially frequent among college-age adults.
Binge drinking: having five drinks in a short period of time
Heavy-use drinking: having five drinks on the same occasion five or mire times in a 30-day period.
Among college students, binge drinking and heavy-use prevalence rates are 43,5 and 16 percent.
Binge drinking can have serious consequences
More men than women have problems with alcohol, though

Two types of anorexia nervosa:
Typically begins in the early to middle teenage years, often after an episode of dieting and the occurrence of life stress.
Lifetime prevalence: less than one percent
10 time more frequent in women than in men.
Suicide rates are quite high for people with anorexia
Physical consequences of anorexia nervosa
Self-starvation and use of laxatives produce numerous undesirable biological consequences in people with anorexia nervosa.
Prognosis
Between 50 and 70 percent of people with anorexia eventually recover.
Recovery often takes 6 to 7 years, and relapses are common before a stable pattern of eating and weight maintenance is achieved.
Anorexia nervosa is a life-threatening illness.
Bulimia nervosa
DSM-5 criteria for bulimia nervosa
Involves episodes of rapid consumption of a large amount of food, followed by compensatory behavior, such as vomiting, fasting, or excessive exercise, to prevent weight gain.
Binge has two characteristics:
Bulimia nervosa is not diagnosed if the bingeing and purging occur only in the context of anorexia nervosa and its extreme weight loss.
The diagnoses in such a case is anorexia nervosa, binge-eating/purgning type.
The key difference between anorexia and bulimia is weight loss.
People with bulimia do not lose a

Chapter 12
Sexual disorders
Sexual dysfunctions are defined by persistent disruptions in the ability to experience sexual arousal, desire, orgasm, or by pain associated with intercourse.
Paraphilias are defined by persistent and troubling attractions to unusual sexual activities or objects.
Definitions of what is normal or desirable in human sexual behavior vary with time and place.
Culture influences attitudes and beliefs about sexuality.
Gender and sexuality
Women tend to be more ashamed of any flaws in their appearance than do men, and this shame can interfere with sexual satisfaction.
For women, sexuality appears to be more closely tied to relationship, status, and social norms than for men.
Among women with sexual symptoms, more than half believe their symptoms are caused by relationship problems. Men are more likely to think about their sexuality in terms of power than are women.
There are many parallels in men’s and women’s sexuality.
The sexual response cycle
Four phases in the human sexual response cycle
Sexual dysfunctions
Sexuality usually occurs in the context of an intimate personal relationship.
Our sexuality shapes at least part of our self-concept.
When sexual problems emerge, they can wreak havoc on our self-esteem and relationships.
Clinical descriptions of sexual dysfunctions
The DSM-5 divides sexual dysfunctions into three categories:
Separate diagnoses are provided for men and women.
The diagnostic criteria for all sexual dysfunction specify that dysfunction should be persistent and recurrent and should cause clinically significant distress or problems with functioning.
A diagnoses of sexual dysfunction is not made it the problem is believed to be due entirely to a medical illness or another psychological disorder.
Many people with problems in one phase of the sexual cycle will often report problems in another phase. Some of this may just be a vicious circle.
Sexual problems in one person may lead to sexual problems in the partner.

Chapter 13
Disorders of childhood
Most theories of childhood disorder, consider childhood experience and development critically important to adult mental health.
Before making a diagnosis of a particular disorder in children, clinicians must first consider what is typical for a particular age.
Some childhood disorders are unique to children.
The more prevalent childhood disorders are often divided into two broad domains,
Children and adolescents may exhibit symptoms form both domains.
Across cultures, externalizing behaviors are consistently found more often among boys and internalizing behaviors more often among girls, at least in adolescence.
Childhood disorders involve an interaction of genetic, neurobiological, and psychological factors.

DSM-5 criteria for attention-deficit/hyperactivity disorder
Although children with ADHD are usually friendly and talkative, they often miss subtle social cues.
Children with ADHD can know what the socially correct action is in hypothetical situations but be unable to translate this knowledge into appropriate behavior in real-life social interactions.
DSM-5 includes three specifiers to indicate which symptoms predominate
The combined specifier comprises the majority of children with ADHD.

Late life and neurocognitive disorders
As we age, physiological changes are inevitable, and there may be emotional and mental changes as well.
Many of these influence social interactions.
The problems experienced in late life
Mental health is tied to the physical and social problems in a person’s life.
No other have more of these problems than the elderly.
As people age, the quality of depth of sleep declines.
Sleep apnea: a disorder in which a person stops breathing for seconds to minutes during the night. Increase with old age.
Several problems are evident in the medical treatment available during late life.

The DSM criteria are the same for older and younger adults.
The process of diagnoses must be considered with care. DSM criteria specify that a psychological disorder should not be diagnosed if the symptoms can be accounted for by a medical condition or medication side effects.
Clinicians must be extremely careful to consider the interactions between physical and psychological health.

Personality disorders
The personality disorders are a heterogeneous group of disorders defined by problems in forming a stably positive sense of self and with sustaining close and constructive relationships.
People with personality disorders experience difficulties with their identity and their relationship in multiple domains of life, and these problems are sustained for years.
Their personality problems are evident in cognition, emotion, relationships, and impulsive control. The symptoms of personality disorders are pervasive and persistent.
The DSM-5 approach to classification
In the DSM-5, the 10 different personality disorders are classified in three clusters, reflecting the idea that these disorders are characterized by:
Many people with psychological disorder will also experience a personality disorder.
Comorbid personality disorder are associated with more severe symptoms, poorer social functioning, and worse treatment outcomes for may conditions.
Diagnostic reliability
Using structured interviews and multiple informants can improve reliability.
Comorbidity
Personality disorders tend to be comorbid with each other.
