Q

Depressive Disorders

A
  • feature persistent and pervasive feelings of sadness

- depression is the leading risk factor for suicide

24
Q

Two primary depressive disorders

A

1) Major Depressive Disorder

2) Dysthymic Disorder (or Dysthymia)

25
Major Depressive Disorder
severe negative moods or loss of interest in pleasurable activities - persistent, significant, impairing; can be recurrent
26
Dysthymic Disorder
mild to moderate depressed mood (now called - Persistent Depressive Disorder)
27
Gender Difference in Depressive Disorders
women are TWICE as likely than men to be diagnosed with depression due to - "role stress" and internalization vs externalization
28
"Role Stress"
women being overworked and under-supported; subtle and not subtle oppression
29
Internalization vs Externalization
women respond to stressful events by "internalizing" their feelings, which leads to depression and anxiety - men "externalize" with alcohol and violence
30
Bipolar Disorders
characterized by periods of mania and frequently alternating with periods of depression
31
Manic episodes
periods of elevated mood, increased activity, distractibility, racing thoughts, decreased need for sleep
32
Severity of mania
distinguished Bipolar I (mania) from Bipolar II (hypomania)
33
Biological components of Depressive and Bipolar Disorders
Genetics - genetic contribution for major depression is moderate, while genetic contribution for bipolar disorder is quite strong - Neurotransmitters and brain structures also implicated in both depressive and bipolar disorders
34
Situational Components
interpersonal losses, life stressors, responses of friends and families
35
Cognitive Components
- Seligman's learned helplessness model | - Beck's cognitive model
36
Seligman's learned helplessness model
expectation that one cannot control important outcomes in life - dogs exposed to shocks gave up escape
37
Beck's cognitive model
people with depression may distort reality and think more negatively
38
Warning signs of suicide
- talking of suicide | - losses, failures; loss of interest in activities
39
Schizophrenia
psychological disorder characterized by distortions in perceptions, emotions, thoughts, or consciousness
40
Psychosis
mental condition that involves distorted perceptions of reality
41
Positive symptoms of Schizophrenia
1) Delusions 2) Hallucinations 3) Loosening of associations 4) Disorganized behavior
42
Delusions
false beliefs - delusions of persecution: belief that others want to harm them - delusions of grandeur: belief of having great power
43
Hallucinations
false sensory perceptions | - auditory most common
44
Loosening of associations
incoherent speech patterns - thought disorder: thoughts seem disorganized or meaningless - clang associations: stringing words together based on their sounds
45
Disorganized behavior
acting strangely - strange movement - poor self-care
46
Negative symptoms of Schizophrenia
behavioral deficits - flat or blunted affect (emotional flatness), slow or no speech, social withdrawal, and lack of goal-directed behavior - associated with a poorer prognosis - associated with structural abnormalities in the brain
47
Biological Factors of Schizophrenia
- genetics plays a role - no single gene, but possibly several genes contribute - neurotransmitter abnormalities and problems with the myelin sheath - structural brain abnormalities: decreased brain weight and enlargement of ventricles
48
Environmental Factors of Schizophrenia
stress in environment contributes to its development - healthy families: none became psychotic - disturbed families: 11% of the children became psychotic and 41% had severe psychological disorders
49
Diathesis-Stress Model
originally developed as an explanation of schizophrenia | - genetic, biological vulnerabilities along with stress from environment interact in the development of the disorder
50
Borderline Personality Disorder
characterized by disturbances in: 1) identity (absence of sense of self) 2) affect (emotional instability) 3) impulses (most commonly self-mutilation)
51
Environmental Factors of Borderline Personality Disorder
- diagnosed more in women - 70-80% of cases report history of physical or sexual abuse or observing extreme violence - early care takes may have been rejecting and critical or may have encouraged dependency
52
Antisocial Personality Disorder
characterized by lack of empathy and remorse
53
Environmental Factors of Antisocial Personality Disorder
- diagnosed more in men - can be manipulative, charming, clever - both biological and environmental causes
54
Psychopath or Sociopath
extreme version of the Antisocial Personality Disorder
55
Biological causes of Antisocial Personality Disorder
lower rate of conditioned responses to pain, danger, and electric shocks
