- residual phase: lessening of symptoms, returning to prodromal-like level

46
Q

genetic/diathesis-stress (biological view of causes of schizophrenia)

A

people who inherit biological predispositions (diathesis) will develop schizophrenia only if certain kinds of events or stressors are also present

47
Q

dopamine hypothesis (biological view of causes of schizophrenia)

A

schizophrenia results from excessive activity of dopamine, which mainly contributes to positive symptoms

48
Q

first generation antipsychotic drugs

A

drugs that help correct grossly confused or distorted thinking by decreasing dopamine

49
Q

phenothiazines

A

first group of effective antipsychotic medications

50
Q

second generation antipsychotic drugs

A

are more effective than first generation drugs and target several neurotransmitters

51
Q

dysfunctional brain structure and circuitry (biological view to causes of schizophrenia)

A

enlarged ventricles, smaller temporal and frontal lobes, less gray and white matter, and abnormal interconnectivity. abnormal dopamine activity is part of a broader circuit dysfunction

52
Q

schizophrenogenic (schizophrenia-causing) mothers (psychodynamic view of causes of schizophrenia)

A

children with mothers who do not care for their needs may develop schizophrenia. little research support

53
Q

operant conditioning (cognitive-behavioural view of causes of schizophrenia)

A

people who are not reinforced to pay attention to social cues may start paying attention to other stimuli-> develop more bizarre responses which are reinforced through attention from others -> schizophrenia

54
Q

misinterpreting unusual sensations (cognitive-behavioural view of causes of schizophrenia)

A
  • strange sensations caused by schizophrenia are due to brain abnormalities
  • when people pay attention to sensations, more symptoms emerge -> develop cognitions based on conclusions from sensations -> schizophrenia
55
Q

multicultural factors (sociocultural view of causes of schizophrenia)

A

schizophrenia rates differ between racial groups and the course and outcome of the disorder vary from country to country

56
Q

social labelling (sociocultural view of causes of schizophrenia)

A

certain symptoms of schizophrenia may emerge because of the diagnosis itself (self-fulfilling prophecy)

57
Q

family dysfunction (sociocultural view of causes of schizophrenia)

A
  • family stress is linked to schizophrenia. parents of people with schizophrenia display more conflicts, struggle to communicate with one another, and are more critical of and over involved with their children
  • expressed emotion = family members openly showing criticism and hostility towards each other, a risk factor for relapse
58
Q

institutionalization (treatment of schizophrenia)

A

put away in public mental hospitals where patients were generally neglected

59
Q

61
Q

drug therapy (treatment of schizophrenia)

A

most effective form of treatment
- first generation antipsychotics (neuroleptic drugs)
- second generation antipsychotics

62
Q

extrapyramidal effects

A

first generation antipsychotic drugs sometimes lead to movement problems
- parkinsonian symptoms (muscle tremors and rigidity) appear within days or weeks
- tardive dyskinesia: extrapyramidal effects involving involuntary movements that patients have after they have taken antipsychotic drugs for more than 6 months.

63
Q

agranulocytosis

A

second-generation antipsychotic drugs can cause decrease in white blood cells, which can be fatal

64
Q

cognitive-behavioral therapies (treatment of schizophrenia)

A
  • cognitive remediation: focuses on cognitive impairments
  • hallucination reinterpretation and acceptance: the aim is to help clients feel more control over their hallucinations and to reduce their delusional ideas
65
Q
