- children with 2 schizo parents have a concordance rate of 46%, 1 parent 13%, one sibling 9%
- joseph found concordance rate of 40.4% MZ twins and 7.4 for DZ. Blind diagnosis report lower concordance for MZ twins
- tienari finland tested 164 adoptees with a shizo mother, 11 had schizo too. 4 out of 197 control adoptees had schizo
- schizo thought to have too many D2 receptors = more dopamine firing
- Amphetamines is a dopamine agonist stimulates relase of dopamine = delusions and hallus
- Anitpsychotic drugs block dopamine activity=eliminate symptoms
- low levels dopamine in ppl with parkinsons. ppl taking l-dopa started to develop schizo symtpoms
