Gottesman, 1991

Family study Outline


Is SZ more common among closer relatives?


Yes, more common among biological relatives of SZ person.


Children with 2 SZ parents = 46% concordance


Children with 1 SZ parent = 13% conconrdance


children with 1 sibling = 9% concordance

Joseph, 2004

Twin Study Outline


Review of all twin studies prior to 2001




concordance rate for MZ twins = 40.4%


concordance rate for DZ twins = 7.4%

Tienari et al, 2000

Adoption study outline


Rate of SZ development among adoptees of SZ parents.


164 SZ mothers --> 6.7% children got SZ


197 control group --> 2% children got SZ

Joseph, 2004 argument

Twin study Evaluation -


MZ twins are treated more similarly


They share more experiences+identity confusion




Therefore, concordance rate reflects environmental factors

Joseph, 2004 claim

Adoption Study evaluation -


SZ children = selectively placed




Parents informed of condition, therefore more prepared

Haracz, 1982

Dopamine Hypothesis evaluation -


Post-mortem studies review


Antipsychotics b4 death = high dopamine lvls


No antipsychotics = normal dopamine lvls




Therefore, antipsychotics may not be suitable for SZ

Copolov and Crook, 2000

Dopamine Hypothesis Evaluation -


Recent, advanced PET scans show no solid evidence of unusual dopamine lvls in SZ patients




Therefore, undermines Dopemine Hypothesis
