exam 6 (last one thank EVERYTHING) Flashcards
Mental Disorders
problematic patterns of thinking, feeling, and behaving that disrupt an individual’s sense of well being and social and occupational functioning.
modern perspective on mental disorders
based on the medical model––DSM
disorder
common set of signs and symptoms
disease
underlying pathological process affecting the body
etiology
pattern of causes for that illness
diagnosis
decision: present or not?
prognosis
typical course over time. how it will respond to treatment.
comorbidity
co-ocurrence of particular disorders
DSM-V (diagnostic and statistical manual 5)
guidelines for diagnosing the presence and severity of mental illnesses.
provides: symptomlogy, threshold and criteria to make a diagnosis, distinguishing characteristics, and the prognoses.
intervention-causation fallacy
the belief that because we intervene and symptoms recede we know the cause of the disease… but we actually do not. we don’t even cure the illness.
biopsychosocial perspective
integrates biological/genetic/neurological influences, psychological influences, and environmental influences
diathesis-stress model
a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences.
diathesis
a predispositional vulnerability
Anxiety disorders
overarching DSM category. has: generalized anxiety disorder, phobic disorder, panic disorder, agoraphobia
everyday “normal” anxiety
psychological and physiological response to stress. adaptive and evolutionary.
anxiety is pathological when
extreme duration and severity, disproportionate to real-life events, and occurs even in absence of precipitating event.
phobic disorder
persistent, excessive, irrational fear and avoidance of specific objects, activities, or situations. specific phobias include animals, environments, situations, and more.
etiology of phobic disorders
preparedness theory–evolutional
temperament based
conditioning–e.g. little albert
social phobia
fear of being publicly humiliated/embarrassed.
Panic disorder
sudden occurrence of multiple physiological and psychological symptoms producing a feeling of terror.
acute symptoms: shortness of breath, palpitations, sweating, dizziness, depersonalization, derealization, fear. symptoms are short lived.
DSM requires: recurrent, unexpected panic attacks, dread/anxiety about future attacks
agoraphobia
fear of public spaces. often a comorbidity of panic disorder.
generalized anxiety disorder
chronic excessive generalized anxiety without a precipitating cause.
need at least 3 of: restlessness, fatigue, concentration problems, irritability, sleep disturbance, muscle tension
etiology of generalized anxiety disorder
modest level of heritability, neurotransmitter GABA, and stress of anxiety provoking situations
shared causal components of anxiety disorders
psychological: personality, coping styles, intellectual functioning
situational: negative life events, social learning
biological: heritability, genetics, neurotransmitters, sensitivity to chemicals
Obsessive Compulsive Disorder (own DSM Category)
two components: obsessions, compulsions
obsessions
frequent, repetitive intrusive thoughts. anxiety provoking.
examples: moral concerns, contamination
compulsions
ritualistic behaviors/actions designed to fend off the obsessive thoughts and help the anxiety
examples: checking, ordering
etiology of OCD
preparedness theory
genetic heritability
brain circuitry involved in habitual behavior
Post Traumatic Stress Disorder (own DSM category)
chronic physiological arousal, recurrent unwanted thoughts or images of the trauma, and avoidance of things that call the event to mind.
symptoms: flashbacks, exaggerated anxiety and reactions, medical conditions
etiology of PTSD
trauma, increased amygdala activity, reduced activity in medial prefrontal cortex, smaller hippocampus
medial prefrontal cortex
involved in calming fear and trauma
DSM Category: Mood Disorders
includes: major depressive disorder, dysthymia/persistent depressive disorder, double depression, seasonal affective disorder
major depressive disorder
severely depressed mood and anhedonia with some combination of: feeling worthless, lethargy, appetite/weight changes, sleep disturbance, energy loss, concentration issues, guilt, thoughts of death/suicide.
need to be like this for 2 or more weeks.
dysthymia/persistent depressive disorder
same symptoms as MDD, but mild to moderate severity. present most of the day, most days, more often than not for two years or longer
double depression
mixture of MDD and dysthymia: dysthymia with periods of major depression
seasonal affective disorder (SAD)
seasonal depression
etiology of depressive disorders
situational components: life stressors
cognitive/behavioral components: negative cognitions (internal, stable, global), interpersonal interactions
biological components: genetics, neurotransmitters (norepinephrine, serotonin), neural structures, biological rhythms
DSM Category: Bipolar Disorders
alternating episodes of depression and mania
bipolar I
severe depression indistinguishable from MDD. periods of mania. ongoing for one or more weeks.
mania
elevated, expansive, irritable mood with increased activity level, grandiose ideas, reckless behavior, lack of sleep. psychotic features could also occur (hallucination/delusion).
depersonalization
state of feeling disconnected from your body, feelings, and environment. like you’re just watching everything happen instead of living it.
derealization
a state of feeling like the world is unreal or strange. It’s a type of dissociation, which is a disconnection between your body, thoughts, and sense of self
bipolar II
severe depression just like MDD but there’s hypomania.
hypomania
a lower level of mania, not as extreme as a full blown manic episode
cyclothymia
dysthymia and hypomania
rapid recycling bipolar disorder
four or more swings between depression and mania in one year.
etiology of bipolar disorders
highest rate of genetic heritability (polygenic, pleiotropic)
neurotransmitters: serotonin and dopamine
stressful life events
polygenic
interaction of multiple genes to create the symptoms
plieotropic
single gene susceptibility to develop disorder.
DSM Category: Personality Disorders
consistently inflexible and maladaptive pattens of thinking, feeling, and behaving or controlling impulses that:
-deviate from cultural norms
-cause distress
-impair social and occupational functioning
have four defining features:
-distorted thought patterns
-problematic emotional responses
-over/under regulated impulse control
-interpersonal difficulties
why personality disorders are controversial
-are they just unpleasant people, or are they actually people with mental illnesses?
-are these distinct types of disorders or just extremes of the big 5?
odd/eccentric cluster
dominated by distorted thinking
-paranoid
-schizoid
-schizotypal
paranoid
guarded, suspicious, hold grudges
schizoid
socially isolated, restricted emotional expression, cold + detached, no desire for social interaction
schizotypal
strange thoughts, emotionally detached, uncomfortable in social situations
dramatic/erratic cluster
impulse control and emotional regulation problems
-antisocial
-borderline
-histrionic
-narcissistic
antisocial
manipulative, exploitative, dishonest, not guilty, break social rules, higher males than females. criminals. sometimes confused with psychopathy, which is a very extreme form of this
borderline
labile, moods shift rapidly, impulse control issues, polarized world view. seem to lack a strong sense of self.
histrionic
attention seeking, seductive behavior, highly emotional, need to be center of attention, need approval of others
narcissistic
envious, need to be the center of attention, entitled, problems with self worth, lack empathy, exploitative
