Q

What is the difference between Type I and Type II Schizophrenia proposed by Crow?

A

Type I = positive symptoms.
Positive (good) premorbid functioning,
Positive response to traditional antipsychotics,
believed to be due to neurotransmitter abnormalities.
Type II = negative symptoms.
Negative (poor) premorbid adjustment,
Negative (poor) response to traditional antipsychotics, and more likely due to structural brain abnormalities
