Abnormal Psychology Flashcards
Biopsychological model
most disorders are not caused by a single factor, they come from a mix of biological, psychological, and social factors
eclectic view
use aspects of different psychological perspectives
Diagnostic and Statistical Manual of Mental Disorders or DSM
super controversial book
help clinicians identify mental disorders
op definitions of all the different disorders
deinstitutionalization
get people into the community
Neurodevelopment Disorder
Intellectual Disability
Autism Spectrum Disorder
Intellectual Disability
impairments of general mental abilities that impact adaptive functioning in 3 areas
- cognitive ability
- social skills
- life skills
symptoms begin before adulthood
comorbid with depression
ADHD, autism spectrum sexual dysfunction
severity determined by adaptive functioning
Autism Spectrum Disorder
people with ASD fall on a continuum from mild to severe
Symptoms of Autism Spectrum Disorder
need to have symptoms in childhood language development social development cognitive development need for routine
language development Symptoms of Autism Spectrum Disorder
impaired delayed language development
echolalia- repeat words or phrases
confuse I or me and use
echolalia
language development Symptoms of Autism Spectrum Disorder
repeat words or phrases
social development Symptoms of Autism Spectrum Disorder
difficulty reading others facial expressions or body language withdrawn in their own world or head inappropriate emotions "egocentric-" just seem it lack empathetic understanding (caught up in own world, not incompassionate) lack imaginative play often don't like being touched
Cognitive development Symptoms of Autism Spectrum Disorder
Highly intelligent to severe intellectual disability
T Grandin
A Turing
Need for routine Symptoms of Autism Spectrum Disorder
need to follow same patterns, habits... like schedules... sometimes engage in repetitive movements -spinning - head banging - rocking
Onset and Prevalence Symptoms of Autism Spectrum Disorder
6 months to 3 years
1/88 cildren
75% both
Causes of Symptoms of Autism Spectrum Disorder
??????? antibodies obese mothers older fathers mirror neurons ????
Treatment for Autism Spectrum Disorder
intense and expensive
academic
behavioral
Attention Deficit and/ Hyperactivity Disorder
persistent pattern of inattention or hyperactivity/impulsivity that interfere with functioning
must be diagnosed by a medical doctor
common diagnosis
Inattention part of ADHD
at least 6 months lack of attention to detail doesn't follow directions disorganized trouble focusing
Hyperactivity/impulsivity part of ADHD
excessive talking
interrupting
at least 6 months
True or false: you need inattention and hyperactivity to have ADHD
false
Do medications cure ADHD?
no just short term
What helps ADHD long term?
behavioral therapy and counseling
Causes of ADHD
???? 1. television and screentime before 3 years old 2. genetics 3. neurotransmitter imbalance (dopamine) 4. brainwaves 5. lead in blood 6. family environment learning 7. Higher arousal thresholds need to be more active
Treatment for ADHD
Europe- behavior coaching and diey
here- drugs and behavior
some studies indicate that drugs show benefits in short term, but, in general, in the long term, no difference between them and behavioral
Tourette’s
multiple motor ticks and one or more verbal tick can occur at different times can change over time ex. clicks coprolalia
Coprolalia
scream obscenities in fits
can vary in severity
more males
part of Tourette’s
Therapy Tourette’s
some drugs?
cognitive behavioral?
symptoms often decrease with age
Conduct Disorder
reptitive persistent patterns of behavior basic rights or others/norms violated
deceitfulness/stealing (lie to get stuff)
physically harm
damaging property
violating rules (serious)
KIDS AND ADOLESCENTS
when they go to jail. often repeat behavior when they get out
lack of empathy
no regard for others
callous unemotional children
What is conduct disorder often misdiagnosed as?
ADHD or OCD
Affect
emotion
DSM criteria for Schizophrenia
2 symptoms for 6 months -delusions = unreal beliefs - hallucinations - disorganized - Other symptoms that cause occupational or social dysfunction
Schizophrenia Spectrum and other Psychotic Disorder
greek for split mind
NOT multiple personality disorder
What are the two ways to classify Schizophrenia?
DSM-5 Criteria
Medical Model
Medical Model classification for Schizophrenia
2 parts negative and positive symptoms negative symptoms missing behaviors that other/most people have [deficit] - lack of affect (emotion) - avolition- lack of drive cognitive defecits - memory troubles - executive functioning impaired (plannign decision making ) - trouble communicating social defecits - trouble in interpersonal relationships positive symptoms have behavior most people don't have - hallucinations - disorganized thinking - delusions
Onset and Prevalence of Schizophrenia
about 1% of population high in lower SES beigins in teen years drastically reduces functions females show signs later than men 20% patients deny
acute schizophrenia
sudden onset 1 event triggers
chronic schizophrenia
gradual decline in functioning
Prognosis of Schizophrenia
NIMH about 10% of Schizophrenic men commit suicide
1/3 mental hospital beds filled by schizophrenics
67% successfully treated ( with lots of support)
1/2 recover about 1/2 need ongoing support
33% not helped by treatment
80% relapse without ongoing treatment
female show signs later 20s
researchers look clues in childhood
ventricles with fluid larger
Diathesis-Stress Model
Diathesis (genetic) stressors
genetic predisposition + trauma
Biological Explanations for Schizophrenia
genetics - inherited genes? brain structure and chemistry - enlarged ventricles -smaller prefrontal cortex - amygdala - excess dopamine viral infection - correlational data - colder in winter, more with schizophrenic - some think genetically predisposed - flu epidemic = trauma neural pruning - neural networks in adolescence have problems - in adolescence wants to be efficient - may be excess pruning - found schizophrenics with abnormal neural connections Diathesis Stress Model - genetic predisposition and stressors
Bipolar Disorder
significant changes in mood, energy, and activity
extreme mood swings from depression to manic episodes
- they switch
- cycles daily or every few months
Symptoms of mania and hypomania
mood changes = euphoria, extreme happiness or intense rage
cognitive changes- inflated self-esteem from wild behavior, intability to evaluate seld, thoughts all over the place
behavioral changes = very talktaitve, increased goal directed behavior
excessive involvement in pleasurable activities
very little sleep
Psychotic symptoms (hallucinations and delusions)
- mania must last 1 week for most of the day
Symptoms of depression (bipolar disorder)
mood changes = intense despair, emptiness
cognitive trouble memory and concentration
suicide ideation
behavioral change- sleep disruptions. lots ot time sleeping
eating
lose interest in pleasurable activities
Onset and Prevalence of Bipolar Disorder
-.5-1%
in males and females
early in 20s manic phase
comorbid with abuse, anxiety, PTSD, heart disease
Treatment for Bipolar Disorder
Lithium, mood stabilizing drugs
Cyclothymic Disorder
low grade and long term bipolar
mood swings less intense
tough to diagnose
people with it tend to be moody and unpredictable
shows multiple symptoms for at least 2 years and is symptom free for less than two months at time
Disruptive Mood Disregulation Disorder
DSM-5
children show persistent irritability/anger with severe out of proportion outbursts of rages
-2-3 rimes/week for 1 year
happens in settings (home school playground)
before age 16 years
6-18 yeats
missing bipolar
Treatment for Disruptive Mood Dysregulation Disorder
medication and therapy
cognitive behavioral therapy
Learning Explanation for Mood Disorders
learned helplessness
lack of clear operant (rewards and punshiminets)
environmental (observed parents)
reciprocal determinism (aggect others attention for depression)
Biological Explanations for Mood disorders
genetics hormones brain structure thyroid neurotransmitters (seratonin)
Cognitive Explanations for Mood Disorders
pessimistic explanatory style external locus of control internal locus of control cognitive dissonance overgeneralization misiniterpretation of life events learned helplessenss
Psychotherapy
broad term for any type of therapy that relies on psychological explanations and treatment
- healthy and ill people can use it
Methods of Therapists
- diagnose problems DSM-5
2. determine treatment strategy –> most use an eclectic approach
etiology
history and causes of a disorder
heestory and keeeeesses
psychopathology
a disorder of the mind; a psychological illness
comorbidity
overlap of 2 disorders
drug abuse and anxiety disorders are often morbid b/c people use drugs/alcohol to self-medicate to relieve anxiety
concordance
degree that 2 individuals share the same disorder, disease, characteristic
- we talked about this when we covered twin studies
Prevalence
how often a disorder occurs in a population
Incidence
# of new cases diagnosed in a time period psyxhologists interested in disorders when the incidence rates change over time
Psychological Assessment
set of tests to help understand an individual
a complete assessment should include
- physical exam
- interview with individual and others in his/her life
- psych tests (like the ones we’ve already talked about)
- therapists use these assessments and the DSM-5
- DSM-5 gives operational definitions of psychological disorders
- it lists symptoms but it doesn’t give causes
Criticisms of DSM-5
published in May 2013 after heated debates on many topics
2 major areas of diasgreement are autism and personality disorders
3 major sections of DSM-5
Section 1: DSM-5 basics (an introduction and directions about how to use the manual)
section 2: Diagnositc criteria and codes (the lists of symptoms needed to diagnose a disorder)
section 3L categories that need more research
Does the DSM-5 include info about treatment?
nope
Anti-deptressants
EFFECT: decrease negative mood help restore sleep cycles HOW: alter neurotransmitter levels (serotonin and epinephrine) Brain structure altered) EX tricyclics (older not often used) MAO inhibitors (potent, highly interactant, not used often) SSRIs such as Prozac, Paxil, Zoloft
Anti-anxieties (tranquilizers)
EFFECT: reduce stress relax muscles decrease panic sleep aid HOW: allow GABA to work better depress overactive sympathetic NS EX Barbiturates (older, addictive, not used often) [pirate, related to fear] Benzodiazepines- valium, Xanax, Atavan, Klonopin [Ben---> bend ---> legal]
anti-psychotics (neuroleptics)
EFFECT
best treatment for schizophrenia becuase reduces the positive symptoms
HOW
dopamine antagonists (block receptors)
EX
older drugs had serious side effects (Tardive Dyskinesia)
newer druds with less side effects such as Haldol, Zyprexa, Risperdal
Other important drugs
Reduce mania and depression Lithium, Depakote
reduce ibsessions SSRI ANAfranil (fran–frantic– obsession)
Psychological Disorders
any behaviors that are at least partly emotional and severe enough to cause a person to
- harm himself/herself or others (phsyical and/or emotional)
- not function effectively (maladaptive behaviors) or at risk
- seem unusual- both statistically and deemed abnormal by majority in society
- behavior is irrational, indefensible, unjustifiable atypical, disturbing
Biological perspective
medical
disorders are a result of physiological problems
could be a neruotransmitter or hormone imbalance, brain damage, brain structure, abnormalities, genetic abnormalities, certain drugs
therefore, disorders can be treated with drugs, or rarely surgery
logical to think physiological, bad brain body
Psychoanalytic/psychodynamic
unconscious problems such as early conflicts, defense mechanisms, or imbalance between id, efo, superego
Neo- freudians claimed that interpersonal, social problems caused disorders
therefore treatment is psychoanalysis to determine the root of the conflict
anal for Freud
can’t analyze your own conflict
C B unconscious
see saw that won’t stop moving
Learning
behaviorism
disorders are strictly a behavioral problem; it isn’t a symptom of an underlying problem
result of environmental repsonse (punsihsments and rewards after stressful situations)
learning (acquisition) of inappropriate behaviors
therefore, treatment is to tuse classical or operant conditioning to unlearn maladaptive pattens
(extinction of behavior)
environment–> response, repeatm relearn
Cognitive
disorders are a result of faulty thinking about yourself, situations
like behaviorists, cognitive therapists see symptoms as disorder
therefore, treatment is cognitive therapt to correct the maladaptive thinking patterns
brain has faulty
all cogged up
