Question 6

PSYCHOPATHOLOGY

Answer 6

Mental illness.

Often studied using a failure analysis approach. Examining breakdowns to understand healthy functioning.

Question 7

MENTAL DISORDER CRITERIA (WHAT IS ABNORMAL?)

Answer 7

• Statistical rarity - but not all uncommon things are bad and not all mental illness is uncommon.
• Subjective distress - often bad, but sometimes feel good (like manic phase of bipolar)
• Impairment - Most interfere with people’s ability to function. But other things that aren’t mental illness also interfere (like laziness)
• Societal disapproval - can be a factor. But not everything we disapprove of is a mental disorder (like racism)
• Biological dysfunction - some yes (schizophrenia), some no (phobias)

Question 8

FAMILY RESEMBLANCE VIEW

Answer 8

According to this view mental disorders don’t all have one thing in common. They are similar, but there are differences (like in a family).

Question 9

CHLORPROMAZINE

Answer 9

One of the first drugs used in mental hospitals. Provided some relief from symptoms of schizophrenia and other disorders marked by a loss of contact with reality.

Question 10

PSYCHIATRIC DIAGNOSES ACROSS CULTURES

Many mental disorders, especially those that are severe, appear to exist in most and perhaps all cultures.

Question 12

MISCONCEPTION: PSYCHIATRIC DIAGNOSIS IS JUST PIGEONHOLING.

Answer 12

We deprive people of their uniqueness, and imply that all people in the same category are alike in all important respects.
No - a diagnosis implies they are alike in at least one important respect. People are very different. Can also make communication easier, especially between mental health professionals.

Question 13

MISCONCEPTION: PSYCHIATRIC DIAGNOSES ARE UNRELIABLE.

Answer 13

Interrater reliability is usually high. But lower for personality disorders.

Question 14

MISCONCEPTION: PSYCHIATRIC DIAGNOSES ARE INVALID

Answer 14

Don’t provide us with any new information. Just labels for behaviour we don’t like.

DEPRESSIVE REALISM

Answer 38

Individuals with mild depression actually have a more accurate view of circumstances. But depressed people are also less attentive to reality.

Question 39

LEARNED HELPLESSNESS

Answer 39

Tendency to feel helpless in the face of events we can't control. Martin Seligman, experiments with dogs. People with depression attribute failure to internal factors, and success to external factors.

Question 40

BIOLOGY IN DEPRESSION?

Answer 40

Twin studies suggest genes exert a moderate effect on the risk of major depression. Stress-sensitive gene? More research needed. Low level of norepinephrine and diminshed neurogenesis. Many patients have problems with the brain's reward and stress-response systems. Decreased dopamine.

SUICIDE

Answer 41

Major depression and bipolar disorder at higher risk of suicide than most other disorders. Bipolar 15 times more likely than general population. Also some anxiety disorders and substance abuse. People are only acutely suicidal for a short window of time, so intervention is critical. 12 to 13 people out of 100, 000 commit suicide. 3 times as many man as women.

MAJOR SUICIDE RISK FACTORS

Answer 42

``` Depression Hopelessness Substance abuse Schizophrenia Homosexuality (social stigma) Unemployment Chronic, painful, or disfiguring illness Recent loss of a loved one (death or divorce) Family history of suicide Personality disorders Anxiety disorders Old age, especially in men Recent discharge from a hospital. ```

Motor problem, including extreme resistance to complying with simple suggestions, holding the body in bizarre or rigid postures, or curling up in a fetal position.

Question 52

BIOLOGICAL CAUSES OF SCHIZOPHRENIA

Answer 52

- Brain abnormalities. Typically central ventricles are enlarged. Suggests brain deterioration. Grey matter loss. - Increased size of sulci. - Decreased size of temporal lobes, activation of the amygdala and hippocampus, basal ganglia, and symmetry of the brain's hemispheres. - Hypofrontality. Front lobes less active when engaged in demanding mental tasks. - Dopamine pathways. - Genetic links.

Question 53

DIATHESIS-STRESS MODEL

Answer 53

Perspective proposing that mental disorders are a joint product of genetic vulnerability, called a diathesis, and stressors that trigger this vulnerability. Idea that 10% of people are predisposed to schizophrenia. Have schizotypal personality disorder. - social withdrawal, thought and movement abnormalities, learning and memory deficits, elevated neuroticism, temporal lobe abnormalities, impaired attention, eye movement disturbances when tracking moving objects. But most people with a vulnerability do not develop schizophrenia.

Question 54

POSITIVE SYMPTOMS OF SCHIZOPHRENIA

Answer 54

Symptoms ADDED to what normal people experience. Delusions, hallucinations, disordered thoughts and speech, etc.

Question 55

NEGATIVE SYMPTOMS OF SCHIZOPHRENIA

Any characteristic of a person's actions, thoughts, or feelings that could be a potential indicator of a mental disorder.

Question 57

SYNDROME

Answer 57

A constellation of interrelated symptoms manifested by a given individual. - must involve distress or impaired functioning - the source must be located within the person - can't be purely explained as an effect of poverty, prejudice, or social forces.

Question 58

MULTIPLE CAUSATION

Answer 58

Predisposing causes Precipitating causes Maintaining causes

Question 59

PREDISPOSING CAUSES

Answer 59

Those well in place before the onset of the disorder that make the person susceptible to the disorder.

Question 60

PRECIPITATING CAUSES

Answer 60

Immediate events in one's life that bring on the disorder.

Question 61

MAINTAINING CAUSES

Answer 61

The consequences of a disorder that help to keep it going once it begins.

Question 62

MOOD

Answer 62

A prolonged state that alters a person's thoughts and behaviours. Two main categories of mood disorders in DSM-IV: - major depressive - bi polar DSM-V has many more.

Question 63

TWO MAJOR DISTINCTIONS BETWEEN DEPRESSION AND ANXIETY

Answer 63

- Anxiety tends to be coupled with physiological arousal and hyper vigilance. - Depression tends to entail an absence of pleasure and sense of hopelessness.
