Abnormal Flashcards
DSM-5
Categorical Approach
divides mental disorders into types, defined by a set of diagnostic criteria
DSM-5
Polythetic Criteria Set
clients present with a subset of symptoms, meaning two clients with the same diagnosis may have completely non-overlapping presentations
DSM-5
Nonaxial Assessment
all mental and medical diagnoses are listed together with primary diagnosis first
no more “axis 2”
DSM-5
Diagnostic Uncertainty
- other-specified - when the clinician wants to indicate why symptoms do not meet criteria
- unspecified disorder is when they do not want to indicate why client’s symptoms do not meet criteria
DSM-5
Outline for Cultural Formation
- the client’s cultural identity
- the client’s cultural conceptualization of distress
- the psychosocial stressors and cultural factors that impact the client’s vulnerability and resilience
- cultural factors relevant to the relationship between the client and therapist
Intellectual Disability
Diagnostic Criteria
2 deficits, onset
- deficits in intellectual functions (e.g., reasoning, problem solving, abstract thinking);
- deficits in adaptive functioning that result in a failure to meet community standards of personal independence and social responsibility and impair functioning across multiple environments in one or more activities of daily life
- an onset of intellectual and adaptive functioning deficits during the developmental period.
Intellectual Disability
Etiology
- 5% heredity
- 30% chromosomal changes, toxins
- 10% pregnancy and perinatal problems
- 5% acquired medical issues during infancy or childhood
- 15-20% environmental factors
- 30% unknown
Stuttering
Course/Prognosis
- gets worse when there is social pressure to communicate
- 65-85% of children recover
Stuttering
Treatment
- Reduction of stress @ home
- habit reversal training
- deep breathing training, relaxing muscles in the throat
Autism Spectrum Disorder
Diagnostic Criteria
For a diagnosis of Autism Spectrum Disorder, the individual must exhibit (a) persistent deficits in social communication and interaction across multiple contexts as manifested by deficits in social-emotional reciprocity, nonverbal communication, and the development, maintenance, and understanding of relationships; (b) restricted, repetitive patterns of behavior, interests, and activities as manifested by at least two characteristic symptoms (e.g., stereotyped or repetitive motor movements, use of objects, or speech; inflexible adherence to routines, or ritualized patterns of behavior); (c) the presence of symptoms during the early developmental period; and (d) impaired functioning as the result of symptoms.
Autism Spectrum Disorder
Prognosis
The best outcomes are associated with an ability to communicate by age 5 or 6, an IQ over 70, and a later onset of symptoms.
Autism Spectrum Disorder
Treatment
- shaping and discrimination training
- vocational training and placement
ADHD
Diagnostic Criteria
onset, settings
ADHD is the appropriate diagnosis when the individual has at least six symptoms of inattention and/or six symptoms of hyperactivity-impulsivity and symptoms had an onset prior to 12 years of age, are present in at least two settings (e.g., home and school), and interfere with social, academic, or occupational functioning.
ADHD
Course/Prognosis
About 15% of children with ADHD continue to meet the full diagnostic criteria for the disorder as young adults and another 60% meet the criteria for ADHD in partial remission.
ADHD
Treatment
- Ritalin/methylphenidate
- behavioral interventions- positive reinforcement, time out, etc
ADHD
ADHD in Adults
In adults, inattention predominates the symptom profile.
ADHD
Etiology
lower-than-normal activity and smaller than normal size of the
- caudate nucleus
- globus pallidus
- prefrontal cortex
ADHD
Multimodal Study
showed that the best outcome is from a mixture of medication and behavioral intervention
SLD
Comorbidity
20-30% of kids with SLD have ADHD
SLD
Diagnostic Criteria
six months of presentation (with intervention) of persistent difficulties with reading, writing, math
SLD
etiology
linked to cerebellar-vestibular dysfunction, hemispheric abnormalities, toxins
Tourettes
Tourettes
Diagnostic Criteria
onset age, duration
Tourette’s Disorder is characterized by the presence of at least one vocal tic and multiple motor tics that may appear simultaneously or at different times, may wax and wane in frequency, have persisted for more than one year, and began prior to age 18.
Tourettes
Treatment
- haloperidol and pimozide, effective 80% of the time
- reversal training, relaxation training, psychoeducation
Tourettes
Etiology
elevated levels of dopamine and supersensitivity of dopamine receptors in caudate nucleus
Behavioral Pediatrics
Hospitalization
Hospitalized children are at increased risk for emotional and behavioral problems, and children ages one to four tend to have the most negative reactions to hospitalization.
Behavioral Pediatrics
School Related Problems
Children and adolescents with chronic medical conditions have higher rates of school-related problems (e.g., CNS irradiation and intrathecal chemotherapy for leukemia have been linked to impaired neurocognitive functioning and learning disabilities).
Behavioral Pediatrics
Compliance
Compliance with medical regimens is a particular problem for adolescents. because of peer acceptance concerns
Schizophrenia
Diagnostic Criteria
A diagnosis of Schizophrenia requires the presence of at least two active phase symptoms - i.e., delusions, hallucinations, disorganized speech, grossly disorganized behavior, negative symptoms - for at least one month with at least one symptom being delusions, hallucination, or disorganized speech
Schizophrenia
Prognosis
best outcome associated with:
- acute and late onset
- female gender
- precipitating event
- brief duration of active-phase symptoms
- insight
- family history of mood disorder
- no family history of schizo
Schizophrenia
Concordance Rates
- Siblings- 10%
- Fraternal 17%
- Identical 48%
- Child of two schizo parents 46%
Schizophrenia
Etiology
- Elevated dopamine reason for symptoms
- enlarged ventricles
- smaller than normal hippocampus, amygdala, globus pallidus
- hypofrontality
Schizophrenia
Treatment
Treatment usually includes an antipsychotic drug, cognitive-behavioral therapy, psychoeducation, social skills training, supported employment, and other interventions for the individual with Schizophrenia and psychosocial interventions for his/her family.
Schizophrenia
Expressed Emotion (EE)
family based interventions are most effective when they target high levels of of EE, which have been linked to relapse and hospitalization
Delusional Disorder
Diagnostic Criteria
one or more delusions that last a month
Delusional Disorder
Types
- erotomanic (belief that someone is in love with you)
- grandiose (believes they are great but unrecognized)

Schizophreniform Disorder
Diagnostic Criteria
The diagnostic criteria for Schizophreniform Disorder are identical to those for Schizophrenia except that the disturbance is present for at least one month but less than six months and impaired social or occupational functioning may occur but is not required.

Diagnostic Criteria
Brief Psychotic Disorder is characterized by the presence of one or more of four characteristic symptoms (delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior) with at least one symptom being delusions, hallucinations, or disorganized speech.
Symptoms are present for at least one day but less than one month with an eventual return to full premorbid functioning.

catecholamine hypothesis
deficiency in norepiphephrine
MDD
indolamine hypothesis
low levels of serotonin
MDD
other etiology hypotheses
- elevated levels of cortisol (stress hormone)
- shrinkage of the hippocampus
MDD
Behavioral Theory of Depression
Lewinsohn’s behavioral theory attributes depression to a low rate of response-contingent reinforcement. (operant extinction of social behaviors)
MDD
learned helplessness model
Seligman’s learned helplessness model proposes that depression is due to exposure to uncontrollable negative events and internal, stable, and global attributions for those events. A reformulation of the theory by Abramson, Metalsky, and Alloy emphasizes the role of hopelessness.
MDD
Beck’s Depressive Triad
negative illogical self-statements about oneself, the world, and the future
MDD
Treatments
TCAs, SSRIs (first-line), MAOIs (for those who don’t respond to other drugs)

Suicide
Gender
Suicide attempters (vs. completers) are most likely to be female.
Suicide
Paradoxical Depression Improvement Effect
