The (good) effects of antipsychotic medicine are best illustrated by remembering how those resulted "an emptying of psychiatric hospitals".
From wikipedia's Chlorpromazine
The effect of this drug [Chlorpromazine] in emptying psychiatric hospitals has been compared to that of penicillin and infectious diseases. But the popularity of the drug fell from the late 1960s as newer drugs came on the scene. From chlorpromazine a number of other similar antipsychotics were developed. It also led to the discovery of antidepressants.
Chlorpromazine largely replaced electroconvulsive therapy, psychosurgery, and insulin shock therapy. By 1964, about 50 million people worldwide had taken it. In 1955 there were 558,922 resident patients in American state and county psychiatric hospitals. By 1970, the number dropped to 337,619; by 1980 to 150,000, and by 1990 between 110,000 and 120,000 patients.
Anyone with a personal stake or interest in schizophrenia, should think about those numbers very carefully. A comforting thought for anyone impacted with schizophrenia is that it is mostly of biological origin and there will be improved and better targeting medicine available. A horrible horrible thing is that I may have discovered a very good target protein for designing a medicine which would fix the schizophrenia's key illness mechanism. As a newly graduated biochemist I thought pharmaceutical companies or university PhD programs would be interested about this "discovery"; as I even had a letter of recommendation from a pharmacy professor (a specialist in psychiatric medicine) certifying that I have apparently discovered a new & interesting model of schizophrenia. When applying for all relevant job positions all over the world, I soon found out exactly no one was interested. Apparently the HR departments were unprepared for this kind of "innovative" applicants.
It isn't very funny, considering I spend a year! at a university library building a disease model; read ~10,000 Medline abstracts, 100+ full articles, 10+ full books. All that just for the purpose of following all the known clues that might lead to the schizophrenia's root cause. Oh and I started that massive modeling because I knew I was very good in building abstract models; for example patent office had been kind to give me patents. And the situation isn't particularly funny for the schizophrenics and their family members eater. ~10% of schizophrenics will end up killing themselves during their lifetime. Considering the average lifetime prevalence of schizophrenia worldwide being ~0.7%, you could estimate there being 7 billion * 0.007 = 49 million schizophrenics out there and about 5 million of them will commit suicide. If we further assume a post diagnostic average lifespan being 35 years, that gives us a an estimate of 142,000 schizophrenic suicides per year - roughly 400 suicides per day. And I've been sitting for years on information that might significantly change those numbers.
So dear schizophrenics (and your beloved relatives), Yes it really is ironic that the information you need the most in this world may already have been found (who knows maybe even by other researchers) but that critical information may just have be neglected. And don't blame me for that!. I really begged a relevant job or any kind of grant money from all possibly instances - even instances which are supposed to exist just for financing making this kinds of "discoveries" starting from NARSAD and ending to the Scottish Rite of Freemasonry.
The only one who has seen that novel schizophrenia model is that pharmacy professor - who warned me he would give the 20 page handout tough review. Couple of weeks later I called him and asked "am I barking a right tree? In short, his answer was: "YES".
That said, schizophrenics should not kill themselves, nor quit the medicines. One day there will be a new kind of specifically targeting antipsychotic medicine; without the side effects of these current (quite unspecifically) binding antipsychotics. Oh yes, and someone really claims to want to find the cause and cure for the schizophrenia they can feel free to finance a PhD study position for me - in which no actual medical experiments are needed. The model is new, good, and enough ready to be written on paper. If you are a Bill Gates and want it, finance it.
