Psychological Disorders - Mood Disorders Flashcards
Bipolar disorder
Shift in moods between two states (poles)
Depression to mania characterized by high energy, impulsiveness, euphoria
Mood disorders - psychological factors
> Psychoanalytic - unresolved childhood issues, symbolic expression of anger
Attachment - insecure attachments, separations, losses increase vulnerability
Behavioural/learning - reduction in positive reinforces from others. E.g. learned helplessness, ruminative coping style
Cognitive research - cognitive distortions and attributions of events
Bipolar depressive disorders
Mania as well as depression (i.e. - two poles)
Bipolar disorder
Cychlothymic disorder
Unipolar Depressive Disorders
> European Americans have highest risk, but African and Hispanic Americans more severe
Average age of onset is 32 (15-24 highest risk of major depressive episode
Major depression
Dysthymic disorder
Mania - general
A distinct period of abnormally elevated, expansive, or irritable mood, lasting at least 1 week (or requiring hospitalization)
3 criteria must be met to a ‘significant degree’ (4 if mood is irritable instead of elevated)
Bipolar I vs II
Bipolar I > presence of manic episode
Bipolar II > one or more depressive episodes with at least one hypomanic episode (no full manic episode required)
Major depression
Extreme sadness (dysphoria) or extreme apathy plus four other symptoms for 2+ weeks May be single or repeated episodes
Hypomanic episode - general
Distinct period of abnormally elevated, expansive or irritable mood, lasting at least 4 days
> 3 criteria must be met to a significant degree, 4 if mood is irritable instead of elevated
> Not severe enough to hospitalize - no psychotic features
Mood disorders - sociocultural factors
Depression more likely among people of lower social status
Cross-culturally, more women than men
> Biological - hormonal imbalance (ovarian hormones may influence serotonin levels)
> Psychological - ruminative coping, relational style
> Social - less power, more victimised, gender-role socialization
Mood disorders - general
Significant change in emotional state.
Most experience some depression, but clinical depression specific length of time and symptoms
Symptoms for mood disorders can exist in absence of triggering events
Dysthymic disorder
Less severe, more chronic form of depression
Depressed mood plus two other symptoms lasting at least two years
Cyclothymic disorder
Less severe but more chronic form of bipolar
Alternates between milder periods of mania and moderate depression
Mania (and hypomania) - criteria (7)
> inflated self-esteem or grandiosity
decreased need for sleep (rested after 3 hours/night)
more talkative/ ‘pressured speech’
Racing thoughts
Distractibility
Increased goal-directed activity or psychomotor agitation
Excessive involvement in pleasurable activities with high chance of painful consequences
Mood disorders - biological factors
Genetics
> family, twin and adoption studies show genetic transmission (clearer for bipolar than major depression)
Neurotransmitters
> Serotonin and norepinephrine abnormalities (correlation not always equal causation)
Hormones
> Repeated activation of hormonal stress system may lay ground for depression
