Greenaway, Heather (2012) Dad defends wife who fled to Spain with son to stop Asperger's treatment turning him into 'zombie'. Daily Record. October 1st 2012.
The big question, which hasn't been asked in the story or in the comments, is whether or not the middle-aged son already identified as having Asperger syndrome really does have schizophrenia or psychosis. I'll bet he doesn't, but if he does, it is a fact that mind-deadening and dangerous drugs are pretty much all that medical psychiatry has to offer psychotic people.
A good doctor confronted with a genuinely psychotic patient would not write a prescription for a drug as a first response. A genuinely professional doctor would first do endless medical tests at great expense to search for any of the countless physical illnesses that have psychosis as a symptom, and would also look into any recreational drug use that could be an underlying cause, but when was the last time that you ever met a doctor who would do half of that? Doctors like that are flukes, aberrations. The doctors that I know can't even be trusted to take a proper look at the results of tests that they already ordered themselves, in the few seconds that they spend reviewing the patient's medical records before or during a consultation. Quacks.
