Exam study guide Flashcards
Prevalence & Course of Depressive Disorders
Being diagnosed as early as pre-school, rates steadily increasing, 50% recover w/in 6-9 months some w/o treatment.
Main symptoms of Depressive Disorders
- Sadness
- Anhedonia (diminished pleasure)
- Change in appetite/weight
- Sleep problems
- Psychomotor agitation/retardation
- Fatigue
- Feelings of worthlessness/guilt
- Problems concentrating
- Suicidal ideation w/ or w/o a plan
Symptoms of Mania

B. 3+ symptoms:
- Inflated self-esteem
- Decreased need for sleep
- More talkative than usual
- Increased goal-directed activity
- Distractibility to irrelevant stimuli
- Excessive involvement in pleasurable activities w/ high potential for painful consequences (sex, substances, etc)
Differences between Bipolar I, Bipolar II, and cyclothymic disorder
BP I: FULL manic episode + MDD
BP II: Hypomanic + MDD
Cyclothymic: Milder; hypomania instead of Mania + Dysthymia instead of Depressive episode, MUST be present for 2+ years with no symptom free period for over 2 months
Prevalence & Course of Bipolar Disorder
- 1-2% for BP I
- 0.4% for BP II
- 0.4 -1% for Cyclothymia
- Same across socioeconomic classes + Ethnic groups
- Onset usually between 15-44 years old
- Equally common across genders but… Women ^ depressive episodes + Men ^ manic episodes
Biological Theories of Depression: Genetic Factors, Neurotransmitter Theories, Structural & Functional Brain Abnormalities
- Genetic Factors: genes short/long alleles
- Neurotransmitter Theories: Serotonin & Norepinephrine
- Structural & Functional Brain Abnormalities: Frontal lobe & Shrunken Hippocampus, Abnormal cortisol levels, Metabolic syndrome (poor diets, decreased physical activity, insufficient sleep)
Behavorial theories of depression
learned helplessness theory, levels of social reinforcement
Cognitive Theories of depression:
negative cognitive triad
reformulated learn helplessness theory
rumination
- negative cognitive triad - negative views of self, world, & future
- reformulated learn helplessness theory - Attribution style (internal/external, stable/unstable, global/specific)
- rumination - repetitive thoughts about issue
Sociocultural theories of depression:
Cohort Effect -
Gender differences -
Ethnicity/Race Differences -
- Cohort Effect: low socioeconomic status, changes in social environment
- Gender differences: women are 2x more likely to experience MDD
- Ethnicity/Race Differences: Lowest in Asian-Americans, highest in Latin-American, lower in Afro than Euro Americans
Psychosocial Contributors to Bipolar Disorder
Stressors lead to social more common in Urban than Rural
Genetic Theories of Bipolar Disorder:
Genetic factors -
Neurotransmitter Factors -
- Genetic factors: Identical twins=40% likelihood; fraternal twins + siblings=5-10% likelihood vs general population=1%
-Neurotransmitter Factors: Low serotonin “opens door” to mood disorder +norepinephrine activity: Low sero + low Norep= depression…. low sero+high norep=mania
Biological Treatments for Mood Disorders
Common Drug Treatments for Depression:
- Selective Serotonin Reuptake Inhibitors
- Selective Serotonin-Norepinephrine Reuptake Inhibitors
Biological Treatments for Mood Disorders cont
Mood Stabilizers
- Lithium
- Anticonvulsants and Atypical Antipsychotic Medications
- Electro convulsive therapy
- Newer Methods of Brain Stimulation
- Repetitive transcranial magnetic
simulation, Deep brain stimulation
- more Omega 3 fatty acids
Psychological Treatments for Mood Disorders
- Cognitive-Behavioral therapy
- Interpersonal therapy: Increasing social support & ability to manage situations
Interpersonal and social Rhythm Therapy and Family-Focused therapy
- improve medication adherence, manage stressful life events, and reduce disruptions in social rhythms.
- Getting family involved in therapy to help treat
Defining and Measuring Suicide:
Gender Differences -
Ethnic and Cross-Cultural Differences -
Non suicidal Self-Injury -
- Gender Differences: Women = higher attempt rate (3x men), Men = Higher completion rate (4-6x women) (violent methods)
- Ethnic and Cross-Cultural Differences:2x higher in Euro-Americans than other racial groups (except Native Americans)
- Non suicidal Self-Injury: Significantly injuring oneself w/o intent to die…could be to influence environment, or regulation of emotion
Stressful life events and suicide
Serious illness, abusive environment, Occupational stress ( ^ during times of unemployment)
Personality and Cognitive Factors in suicide
impulsivity, hopelessness
Biological Factors in Suicide
Serotonin
Treatment and Prevention of Suicide:
Treatment of suicidal persons -
Suicide Prevention -
Guns and Suicide -
- Treatment of suicidal persons: psychotherapy + drug therapy once medically stable (goals: keep patient alive, help achieve non-suicidal state of mind, better coping strategies)
- Suicide Prevention: (Means restriction better gun control, safer medications, etc.), Target public education, NICER framework
- Guns and Suicide: having guns increases risk of suicide by 3x for mental disorder + 33x for people w/o disorder
DSM-5 symptoms, Diagnosis, and course schizophrenia
A. 2+ symptoms (1 must be first 3) for most of 1-month period
- delusions
- hallucinations
- disorganized speech
