|
|
|

|
Incidence of schizophrenia is less than 50 percent which indicates that several genes are involved or that having a "schizophrenia gene" impart a susceptibility to develop schizophrenia, the dz itself being triggered by other factors

|
|

True. Children of older fathers are more likely to develop schizo.
|
|
|

|
The positive symptoms of schizo. are caused by overactivity of synapses between dopaminergic neurons of the VTA and neurons in the n. acc. and amygdala.
