Some evidence suggests that neuroleptics are never necessary because a placebo or simple sedative have the same effect. In one of the rare studies comparing use and nonuse of psychiatric drugs in a supportive residence, each group was matched so participants were as similar as possible, then some received neuroleptics and others did not. This information is not widely known because of a truly astounding bias favouring drugs despite all the evidence of their ineffectiveness and harmfulness. In fact, psychiatric drugs harm more people than they help - sometimes irreversibly, even fatally. Despite the terrible damage that can be done, researchers have found that professionals rarely seek people's informed consent.
Some antidepressants can cause suicidal or aggressive thoughts and behaviour.
In other words, it is the exception rather than the rule for the same person to receive any consistent diagnosis from different mental health professionals. Most people who have been in the psychiatric system are survivors of abuse. To have no control over what is happening to their own bodies is to retraumatize them. In fact, to be healthy a person requires more control over one's life, not less. It is erroneously assumed that people must be forced to take advantage of all the good resources that are there to help them.
