hallucinations andor delusions May occur in the context of other psychological disorders not just schizophrenia Schizophrenia a type of psychosis with disturbed thought language and behavior Psychosis and Schizophrenia are heterogeneous Schizophrenia The quotPositivequot Symptom Cluster The Positive Symptoms Active manifestations of abnormal behavior distortions of normal behavior Examples include delusions hallucinations and disorganized speech Delusions Disordered Thought Content Gross misrepresentations of reality Examples include delusions of grandeur or persecution Hallucinations Auditory or Visual mostly Experience of sensory events without environmental input Can involve all senses auditory visual tactile olfactory gustatory The nature of auditory and visual hallucinations findings from SPECT studies amp Broca s area Schizophrenia The quotNegativequot Symptom Cluster The Negative Symptoms Absence or insufficiency of normal behavior Examples are emotionalsocial withdrawal apathy and poverty of thoughtspeech Spectrum of Negative Symptoms Avolition or apathy refers to the inability to initiate and persist in activities Alogia refers to the relative absence of speech Anhedonia lack of pleasure or indifference to pleasurable activities Affective flattening show little expressed emotion but may still feel emotion Schizophrenia The quotDisorganizedquot Symptom Cluster The Disorganized Symptoms Include sever and excessive disruptions in speech behavior and emotion Examples include rambling speech erratic behavior and inappropriate affect Nature of Disorganized Speech Cognitive speech refers to illogical and incoherent speech Tangentiality llgoing off on a tangent and not answering a question directly Loose associates or derailment taking conversation in unrelated directions Nature of Disorganized Affect Inappropriate emotion behavior crying when one should be laughing Nature of Disorganized Behavior Includes a variety of unusual behaviors Catatonia spectrum from wild agitation waxy flexibility to complete immobility Diagnosis of Schizophrenia Two or more positive symptoms negative symptoms andor disorganized portion Last for most days for at least 1 month Lots of variability with little overlap in symptoms Individuals with schizophrenia vary widely from each other Subtypes of Schizophrenia Paranoid Type Intact cognitive skills and affect and do not show disorganized behavior Hallucinations and delusions center around a theme grandeur or persecution The best prognosis of all types of schizophrenia Disorganized Type Marked disruptions in speech and behavior flat or inappropriate affect Hallucinations and delusions have a theme but tend to be fragmented This type develops early tends to be chronic tacks periods of remissions Catatonic Type Show unusual motor responses and odd mannerism echolalia echo words echopraxia echo movements This subtype tends to be sever and quite rare Undifferentiated Type quotWastebucketquot category Major symptoms of schizophrenia but fail to meet criteria for another type Residual Type One past episode of schizophrenia Continue to display less extreme residual symptoms odd beliefs Other Disorders with Psychotic Features Schizophreniform Disorder Schizophrenic symptoms for a few months Associated with good premorbid functioning most resume normal lives Schizoaffective Behavior Symptoms of schizophrenia and a mood disorder are independent of one another Prognosis is similar for people with schizophrenia Such persons do not tend to get better on their own Delusional Disorder Delusions that are contrary to reality without other major schizophrenia symptoms Many show other negative symptoms of schizophrenia Type of delusions include erotomanic grandiose jealous persecutory and somatic Events could be happening unlike schizophrenia but aren t This condition is extremely rare with a better prognosis than schizophrenia Brief Psychotic Disorder Experience one or more positive symptoms of schizophrenia Usually precipitated by extreme stress or trauma Tends to remit on its own Shared Psychotic Disorder Delusions from one person manifest in another person Little is known about this condition Schizotypal Personality Disorder May reflect a less severe form of schizophrenia Schizophrenia Some Facts and Statistics Onset and Prevalence of Schizophrenia worldwide About 02 to 15 or about 1 population Usually develops in early adulthood but can emerge at any time average age is 25 Schizophrenia is generally chronic Most suffer with moderatetosevere impairment throughout their lives Life expectancy in persons with schizophrenia is slightly less than average Premorbid phase before 1st psychotic episode 9 active phase positive symptoms active 9 residual phase often negative symptoms still present repetitive cycle of active then residual phases Schizophrenia affects males and females about equally Females tend to have a better longterm prognosis Onset of schizophrenia differs between males and females Schizophrenia appears to have a strong genetic component Schizophrenia Etiology and Treatment Causes ofSchizophrenia Findings from Genetic Research Family Studies Inherit a tendency for schizophrenia not a specific form of schizophrenia Other family members are at increased risk of schizophrenia Twin Studies Risk of schizophrenia in monozygotic twins is 48 Risk of schizophrenia drops to 17 for fraternal twins Adoption Studies Risk of schizophrenia remains high in adopted children with a biological parent suffering from schizophrenia Summary of Genetic Research Risk of schizophrenia increases as a function of genetic relatedness One need not show symptoms of schizophrenia to pass on relevant genes Schizophrenia has a strong genetic component but genes alone are not enough Causes of SchizophreniaNeurotransmitter In uences Neurobiology and Neurochemistry The Dopamine Hypothesis Drugs that increase dopamine agonists result in schizophreniclike behavior Drugs that decrease dopamine antagonists reduce schizophrenialike behavior Examples include neuroleptics and LDopa for Parkinson s disease The dopamine hypothesis proved problematic and overly simplistic Current theories emphasize several neurotransmitters and their interaction Causes of Schizophrenia Other Neurobiological Influences Structural and functional abnormalities in the brain Enlarged ventricles and reduced tissue volume Hypofrontality less active frontal lobes a major dopamine pathway Viral infections during early prenatal development The relation between early viral exposure and schizophrenia is inconclusive F quot about quot39mand quot r Schizophrenia is associated with diffuse neurobiological dysregulation Structural and functional abnormalities in the brain are not unique to schizophrenia Causes of Schizophrenia Psychological and Social Influences The Role of Stress May activate underlying vulnerability andor increase risk of relapse Family Interactions Families of people with schizophrenia show ineffective communication patterns High expressed emotion hostility criticism intrusiveness in the family is associated with relapse The Role of Psychological Factors Psychological factors likely exert only a minimal effect in producing schizophrenia Medical Treatment of Schizophrenia Historical Precursors Antipsychotic Neuroleptic Medications Medication treatment is often the first line treatment for schizophrenia Began in the 1950s Most reduce or eliminate the positive symptoms of schizophrenia Acute and permanent extrapyramidal and Parkinson slike side effects are common Tardive dyskinesia Compliance with medication is often a problem Psychosocial Treatment ofSchizophrenia Historical Precursors Psychosocial approaches Overview and goals Behavioral token economies on inpatient units Social and living skills training Behavioral family therapy Vocational rehabilitation Psychosocial approaches are usually a necessary part of medication therapy Dissociative Feelings Depersonalization feeling detached from oneself or one s body Derealization feelings of unreality outside objects change shape or size people seem mechanical Dissociative Identin Disorder Multiple personalities identities or quotaltersquot At least 2 distinct identities with own pattern take Unable to recall important information Onset usually in childhood average 15 personalities Prevalence 5 to 1 Characteristic that are high suggestible Dissociative Disorders Depersonalization Disorder Feeling detached from own body or mind in a dream Dissociative Amnesia Generalized amnesia lose all memory including own identity Localized selective amnesia lose memory of specific events usually traumatic during particular period of time Dissociative Fugue Unexpected travel associated with loss of memory Lose memory of own past may assume new identity Dissociative Trance Disorders Trance or I 39 with 39 39 39 39 state in culture Causes Biological vulnerability Twin studies do not support genetic vulnerability to DID Psychological factors Trauma is precipitating events repeated trauma or extreme trauma for DID Child abusechild sexual abuse high risk Suggestibility or ability to autohypnotize False memories Treatment Amnesia amp Fugue Usually get better on their own May help recall events or present information and help integrate into conscious experience Hypnosis and benzodiazepines to aid in recall of events DID No controlled studies of treatment limited success Exposure treatment using PTSD model extinguish cues triggering anxiety and dissociation May use hypnosis to bring memories into conscious awareness CHAPTER 13 DEVEIOPMEN39I39AI DISORDER Attention Deficit Hyperactivity Disorder ADHD An Overview Nature

usually more pronounced at the end of the day Range of Cognitive Deficits Aphasia Difficulty with language Apraxia impaired motor functioning Agnosia Failure to recognize objects Difficulties with planning organizing sequencing or abstracting information An Autopsy is required for a Definitive Diagnosis Alzheimer s Disease Facts and Statistics Nature and Progression of the Disease Deterioration is slow during the early and later stages but rapid during middle stages Average survival time is about 8 years Onset usually occurs in the 60s or 70s but may occur earlier Prevalence of Alzheimer s Disease Affects about 4 million Americans and many more worldwide Prevalence is greater in poorly educated persons and women Prevalence rates are low in ethnic groups Japanese Nigerian Amish Vascular Dementia An Overview Nature of Vascular Dementia Progressive brain disorder caused by blockage or damage to blood vessels Second leading causes of dementia next to Alzheimer s Onset s often sudden stroke Patterns of impairment are variable and most require formal care in later stages DSMIV Criteria and Incidence Cognitive disturbances that are identical to dementia Unlike Alzheimer s obvious neurological signs of brain tissue damage occur Incidence is believed to be about 47 of men and 38 of women Causes of Dementia The Example ofAlzheimer s Disease Current Neurobiological Findings Neurofibrillary tangles occur in all brains of Alzheimer s patients Amyloid plaques accumulate excessively in brains of Alzheimer s patients The role of amyloid proteins Brains of Alzheimer s patients tend to atrophy Multiple genetic abnormalities implicated in Alzheimer s Summary of Cognitive Disorders Cognitive Disorders span a range of deficits Attention memory language and motor behavior Causes

interpersonal relationships empathy and social skills Treatment prognosis is generally poor Cluster A Schizotypal Personality Disorder Overview and Clinical Features Behavior and dress is odd and unusual Most are socially isolated and may be highly suspicious of others Magical thinking ideas of reference and illusions are common Risk for developing schizophrenia is high in this group Many also meet criteria for major depression The Causes Schizoid quot A 39 ofa quot 39 39 genotype 1 I n r Left hemisphere and more generalized brain deficits Treatment Options Main focus is on developing social skills Treatment also addresses comorbid depression Medical treatment is similar to that used for schizophrenia Treatment prognosis is generally poor Cluster B Antisocial Personality Disorder

Psychopathy and Antisocial Personality Disorder Relation between ASPD Conduct Disorder and Early Behavior Problems Many have early histories of behavioral problems including conduct disorder Many come from families with inconsistent parental discipline and support Families often have histories of criminal and violent behavior Neurobiological Contributions and Treatment of Antisocial Personality Prevailing Neurobiological Theories Brain damage Little support for this view Underarousal hypothesis Cortical arousal is too low Cortical immaturity hypothesis Cerebral cortex is not fully developed Fearlessness hypothesis Psychopaths fail to respond with fear to danger cues Gray s model of behavioral inhibition and activation neurobiological dysfunction Reward system overrides the behavioral inhibition system Treatment Few seek treatment on their own Antisocial behavior is predictive of poor prognosis even in children Emphasis is placed on prevention and rehabilitation Often incarceration is the only viable alternative Cluster B Borderline Personality Disorder Overview and Clinical Features Patterns of unstable mood and relationships Impulsivity fear of abandonment coupled with a very poor selfimage Selfmutilation and suicidal gestures are not uncommon Most common personality disorder in psychiatric settings Comorbidity rate are high More often diagnosed in females than males sexist effect Men more likely to be diagnosed with bipolar disorder The Causes Borderline personality disorder runs in families Early trauma and abuse seem to play etiologic role Treatment Options Few good treatment outcome studies Antidepressant medications provide some shortterm relief Dialectical behavior therapy is the most promising psychosocial approach Uses mindfulness awareness of emotions nonjudgmentally Cluster B Histrionic Personality Disorder Overview and clinical Features Patterns of behavior that are overly dramatic sensational and sexually provocative Often impulsive and need to be the center of attention Thinking and emotions are perceived as shallow Common diagnosis in females The Causes Etiology is largely unknown ls histrionic personality a sextyped variant of antisocial personality Treatment Options Few good treatment outcome studies Treatment focuses on attention seeking and longterm negative consequences Targets may also include problematic interpersonal behaviors Little evidence that treatment is effective Cluster B Narcissistic Personality Disorder Overview and Clinical Features Exaggerated and unreasonable sense of self importance Preoccupation with receiving attention Lack sensitivity and compassion for other people Highly sensitive to criticism Tend to be envious and arrogant The Causes Link with early failure to learn empathy as a child Sociological view Narcissism as a product of the llmequot generation Treatment Options Extremely limited research Treatment focuses on grandiosity lack of empathy unrealistic thinking Treatment may also address cooccurring depression Little evidence that treatment is effective Cluster C Avoidant Personality Disorder Overview and Clinical Features Extreme sensitivity to the opinions of others Highly avoidant of most interpersonal relationships Are interpersonally anxious and fearful of rejection The Causes Numerous factors have been proposed Early Development A difficult temperament produces early rejection Treatment Options Several wellcontrolled treatment outcome studies exist Treatment is similar to that used for social phobia Treatment targets include social skills and anxiety Cluster C Dependent Personality Disorder Overview and Clinical Features Excessive reliance on others to make major and minor life decisions Unreasonable fear of abandonment Tendency to be clingy and submissive in interpersonal relationships The Causes Still largely unclear Linked to early disruptions in learning independence Treatment Options Research on treatment efficacy is lacking Therapy typically progresses gradually Treatment targets include skills that foster independence Cluster C ObsessiveCompulsive Personality Disorder Overview and Clinical Features Excessive and rigid fixation on doing things the right way Tend to be highly perfectionistic orderly and emotionally shallow Obsessions and compulsions are E The Causes Are largely unknown Treatment Options Data supporting treatment are limited Treatment may address fears related to the need for orderliness Other targets include rumination procrastination and feelings of inadequacy lEGAl AID l39l39lIICAl IS
