Hello out there? Anyone? Anyone? Bueller? Bueller? I have a couple of questions from my intro psych students: 1) What is the current state of the science regarding the etiology of schizophrenia? How prevalent is the phenomenon of people developing it after prolonged use of stimulant drugs? What is the current thinking re: Genetic predisposition versus environment? 2) How often does sudden inability to recognize faces show up as an early symptom of Alzheimer's, if at all? Thanks for any help you can give me. Nancy Melucci Los Angeles Harbor College
