final 2 Flashcards
Anorexia Nervosa
Eating disorder
- fear of being fat, though not fat
- 90% female
- bone loss, heart strain, stops menstruation
Bullmia Nervosa
Eating disorder
- self induced vomiting
GABA
inhibitory transmitter
Amphetamines
reduce fatigue and appetite
increase dopamine
Endorphins
painkillers
Androgens
Sexual desire
Serotonin
feelings of happiness
Depression
mood disorder
Suicide
rate is reduced in worst stage of depression due to apathy
- Social support can help prevent
Bipolar disorder
depression with periods of mania
Manic state - grandiose plans, no limits to what can be done. Speech rapid and unstoppable
Causes of mood disorders
- Biological
Reserpine induces depression by depleting
monoamines (norepinephrine, dopamine, and serotonin
// environmental/learning - decrease in positive reinforcement from environment
// personality-based vulnerability - Freud believed early losses, rejection create vulnerability for later depression
Brown and Haris found that women who lost their mom before
age 11 were 3x more likely to become depressed because of a recent loss than women who didn’t
// Humanistic - this generation focuses too much on personal attainment instead of others and react more strongly to their own failures
// Cognitive process
Depressive cognitive triad
Depressive attributional pattern
// Sociocultural - much less depression in collectivist cultures, strong connections in family
In North American, depression = guilt/personal inadequacy
• In Chinese/African/Latin cultures, depression = fatigue, loss of appetite, sleep problems
• Women are no more likely than men to be depressed in developing countries
Learned helplessness theory
Causes of mood disorders
- depression happens
when people expect bad events and believe that there is
nothing they can to prevent them
• Negative attributions are personal, stable and global:
Its my fault, I’ll always be this way, I’m a total loser
Depressive cognitive triad
// Cognitive
causes of mood disorders
negative beliefs about world, oneself and future
- victimize themselves
- remember their failures, not successes
Depressive attributional pattern - bad things are personal,
good things are situational (opposite of self-severing bias)
Cycle of depression
stressful experiences ➡ negative
explanatory style ➡ depressed mood ➡ cognitive and
behavioral changes ➡ stressful experiences
• Breaking the negative explanatory style breaks the cycle
Depressive attributional pattern
Cognitive process
factors that cause mood disorders
- bad things are personal,
good things are situational (opposite of self-severing bias)
Somatoform disorders
complaints of physical symptoms that aren’t physiologically possible
Conversion disorder
Somatoform disorder
erious neurological symptoms
(blindness, paralysis, sensation loss) suddenly occur
• Strange lack of concern about symptom
Glove anesthesia
losing sensation only below wrist, not neurologically possible
- caused by traumatic event
- psychodynamic: ego represses conflict by converting anxiety into physical symptom
Hypochondriasis
Somatoform disorder - being alarmed about any physical symptom, convinced they have serious illness
Pain disorder
experience
intense pain for no reason or out
of proportion
Psychogenic Amnesia
Dissociative disorder
- Person responds to a stressful event with
extensive but selective memory loss
Psychogenic Fugue
Dissociative disorder - person loses all sense of personal identity, gives up customary life, wanders to a new faraway location, and establishes a new identity - Typically ends what person suddenly remembers original identity, mystified
Dissociative Identity Disorder (DID)
Dissociative disorder
multi personality 92% female
Trauma-Dissociation Theory
(DID)
- new personalities occur in response to severe stress, usually from childhood
Schizophrenia
Severe disturbances in thinking, speech, perception,
emotion and behavior
• Schizophrenia means split-mind, but it is not same as
DID
Delusions, hallucinations, paralogic, overinclusion
Delusions (schizophrenia)
Schizophrenia
- false beliefs sustained in face of opposing evidence
• Delusions or persecution (out to get me) or delusions of
grandeur (extreme importance)
Hallucinations (schizophrenia)
Schizophrenia
- false perceptions of reality (auditory mostly, also
visual or tactile)
Paralogic
Schizophrenia
California has water and sand so its the promised land
Overinclusion
Schizophrenia
- “fruitful year” means pears and apples
Schizophrenia types 1
Paranoid, disorganized, catatonic
- motor disturbances: muscle
rigidity or random/repetitive movements.
• Alternate between stuporous states - oblivious to
reality, can be molded and stay that way for hours
• And agitated excitement - can be dangerous to
others)
Schizophrenia types 2
Type 1 - positive symptoms: delusions, hallucinations, disordered speech/thoughts possibly treatable Type 2 - Negative symptoms: lack of emotion, loss of motivation, absence of normal speech rarely treatable
Causes of schizophrenia
// Biological factors exist
- problems with DISC 1, protein that guides new neural connections
Abnormalities in thalamus (responsible for sensory input)Structural differences in type 2, so hard to recover,
Dopamine hypothesis
// Psychological
Freud
- schizophrenia is extreme regression
Cognitive
- Defect in attention mechanism, overwhelmed by stimuli
// Sociocultural
• Social causation hypothesis - higher rates of
schizophrenia in poor areas due to the higher
stress that low income cause
• Social drift hypothesis - schizophrenia causes
lower occupational functioning, so schizophrenic
people move to low-cost urban housing populations
// Environmental
Stressful life events play important roll
• More likely to relapse if returning to home that is high in expressed emotion
Dopamine hypothesis
Biological
Causes of schizophrenia
- positive symptoms are produced by an over activity of dopamine in motivation, emotion and cognitive function areas
Antisocial Personality disorder
Personality disorder - irresponsible and antisocial, impulsive needs, lack of empathy, highly manipulative, no conscience // Causes - Biological, amygdala or prefrontal cortex dysfunction causes lower heart rates under stress - Psychological/environmental - lack of conscience (no superego)
