SCHIZO BIO EVAL - gentic vulnerability

Question 1

SUPPORT FOR GENETIC VULNERABILITY - POINT

Answer 1

there’s strong evidence for genetic vulnerability to schizo from a range of sources

Question 2

SUPPORT FOR GENETIC VULNERABILITY - EVIDENCE

Answer 2

GOTTESMAN - showed how genetic similarity and shared risk of schizo are closely related

ADOPTION STUDIES TIENARI ET AL - shows that kids of schizo sufferers are still at a greater risk of schizo if adopted into families with no history of the condition

Question 3

SUPPORT FOR GENETIC VULNERABILITY - evidence/expl continued

Answer 3

also evidence from studies conducted at the molecular level showing 108 gene varations that increase the risk of schizo (RIPKE)

Question 4

SUPPORT FOR GENETIC VULNERABILITY - Link/explanation

Answer 4

although these findings dont mean schizo is entirley genetic it does suggest gentic factors make some people more vulnerable to developing schizo than others

Question 5

ISSUES x DEBATES - BIOLOGICAL REDUCTIONISM - point

Answer 5

clear evidence to show that enviro factors also increase risk of developing schizo

Question 6

ISSUES x DEBATES - BIOLOGICAL REDUCTIONISM - evidence

Answer 6

these enviro factors also icnlude bio and psyc influences

biological risk fctors include birth compications (MORGAN ET AL ) and smoking THC rich cannabis in teen years

psycho risk factors include childhood trauma which leaves people more vulnerable to adult mental health problems in general but now evidence for ptclr link with schizo

study by Mokved et al found 67% people with schizo and related psychotic conditions reported at least one childhood trauma as opposed to 38% of match group with non psychotic mental health problems

this means genetic factors alone cannot provide a complete explanatino for schizophrenia
