23
Q
Is prevalence schizophrenia equal in men and women?
A
- men and women experience the disorder equally
- men experience symptoms 4-5 years earlier than women, are more likely to exhibit negative symptoms and to have a chronic, deteriorating course
24
Q
Genetic contribution
A
The influence of genes on the development of a mental illness or disorder
25
Epigenetics
The study of modifications of gene expression that are caused by mechanisms other than changes in the underlying DNA sequence
26
Schizophrenia study genomics discoveries
- many genes involved govern the functioning of neurotransmitters such as dopamine and glutamate
- the strongest findings concern chromosome 6, which is heavily involved in immune functioning
- many alleles that indicate high risk for schizophrenia also indicate high risk for bipolar disorder
27
Schizophrenia as a neurodevelopmental disorder?
Recent research found allele mutations, deletions and duplications might play a role in schizophrenia
28
Neuropsychological testing indicates that most people with schizophrenia are:
Cognitively impaired and may have a low IQ
29
Brain imaging reveal diffuse brain pathology in schizophrenia. Of note are:
- abnormally reduced frontal brain volumes and frontal brain blood flow
- abnormalities in the left temporal lobe, which is strongly connected to the frontal lobes, the amygdala, and the hippocampus
30
Dopamine hypothesis
- he theory that dopamine plays a major role in schizophrenia
- studies drugs either inhibit dopamine (antipsychotics) and observations many drugs stimulate dopamine cause hallucinations
31
Other neurotransmitters and schizophrenia
- dopamine
- serotonin
- glutamate (lower levels in prefrontal cortex and the hippocampus)
32
Etiology schizophrenia- developmental factors
- most people diagnosed with schizophrenia show problems in childhood
- pregnancy and birth complications including prolonged labour, preterm delivery, low birth weight, and fetal distress may play a role
- proportion children at risk shoe early signs of motor impairment, cognitive limitations, social withdrawal, and aggression
33
Etiology psychosocial factors schizophrenia
- occurs more often in low SES
- emergence and surge schizophrenia coincided with industrial revolutions and increased urbanization under very poor conditions
- associated with urban living
- developmental factors (which influences which?)
34
Cognitive problems and schizophrenia
- impaired problem solving
- memory deficits
- impaired learning and word recall
35
Research supported subtypes schizophrenia
- impaired problem solving
- memory deficits- memory impaired
- cognitively impaired
- cognitively normal
36
Diathesis
A predisposition or vulnerability for the development of an illness or disorder
37
Hypokrisia
In Meehl's theory, the reduced selectivity with which nerve cells respond to stimuli, especially as seen in schizophrenia
38
Meehl's theory
- biological diathesis (Hypokrisia) caused by single gene
- expression gene affected by other genetic characteristics and psychosocial circumstances leads to cognitive slippage
- cognitive slippage + aversive drift = schizotypia
- moderator characteristics such as intelligence, artistic talent, and personality traits likely influence functioning and may lead to emergence of full blown schizophrenia
39
Cognitive slippage
The mental consequences of Hypokrisia, namely loss of integrated thinking and coherent mental life
40
Aversive drift
In Meehl's theory, the tendency for people with a genetic predisposition for schizophrenia to be perceived negatively end subjected to personal rejection, leading progressively to social withdrawal and alienation
41
Schizotype
A person experiencing cognitive slippage and aversive drift
42
Expressed emotions (EE)
Negative or intrusive attitudes and behaviours directed at the patients (associate in relapse in diagnosed patients)
43
Integrated theories
Interaction between genetics and psychosocial factors probably best explain schizophrenia
44
Markers
Individual characteristics that would predict a person's vulnerability to schizophrenia (continuous performance test, eye tracking dysfunction, Wisconsin card scoring test)
45
Disease markers
Markers that occur in virtually all people with the illness
46
Continuous performance test (CPT)
- participants observe a string of numbers and are asked to respond whenever two identical numbers occur together
47
Endophenotypes
Characteristic deficiencies that underly an observable symptom and have a genetic component; a heredity characteristic that is normally associated with some condition, but is not a direct symptom of that condition
48
Antipsychotic medication
- phenothiazines
- reduce severity mostly of positive symptoms
- 25% show no improvement, 30-40% show mild improvement
- side effects: extra pyramidal symptoms (EPS), tardive dyskinesia (TD)
49
Extra pyramidal effects
Severe side effects of the major tranquilizer a
50
Tardive dyskinesia
Strange muscular movements such as eye twitching and tongue thrusting
51
Maintainence medication
90% relapse if not on antipsychotics, 40% if taking them
52
Atypical antipsychotics:
- cause fewer side effects and maybe more effective for positive and negative symptoms
- target mostly serotonin system
53
Types treatment schizophrenia
- family oriented aftercare
- social skills training
- community based treatment
- cognitive-behavioural treatment
- institutional programs
54
Heterogeneity
The variability and diversity of clinical and biological features seen in schizophrenia; the tendency for people with the disorder to differ from each other in symptoms, family and personal background, response to treatment, and ability to live outside the hospital
- makes predictions difficult
55
Masters & Johnson human sexual response cycle

57
Heel singer Kaplan the human sexual response cycle
Desire, excitement, orgasm
| Desire primarily psychological component to sexual response
58
Classification sexual dysfunction

72
Epidemiological issues of sexual dupes function disorders
- fairly common
- treatment sought mostly for erectile disorder, female orgasmic disorder, premature orgasm (premature ejaculation in men))
- sexual desire problems have become more frequent
- age affects sexual functioning
73
Biological factors sexual dysfunction
- role hormones in sexual desires
- erectile dysfunction is in part related to vascular dysfunction
- tobacco, alcohol, marihuana can affect arousal and sexual function
