adoption studiesrisk for schizophrenia remains high when biological parent has schizophrenia.


Question Answer
behavioral correlatessmooth-pursuit eye movement, reduces ability to track movie objects qith eyes, relatives have same deficit.
the dopamine hypothesissuggests that dysregulation in dopamine and dopamin receptors play central role. (drugs that increase domapin result in schozophrenia, while dugs that decreased dopamine reduce schizophrenia.)
indease dopamineincrease schizophenia
reduce dopaminedescrease schizophrenia
evalution of dopamine theorydoesn't explain all of disorder, antipsychotics block dopamine but relief of symptoms takes several weeks, to be effective antipsychotics must reduce dopamine activity below normal levels. (serotonic, gaba, glutamate and other neutrotransmitters are involved as well.)
