ScienceDaily (Apr. 9, 2008) — Schizophrenia is a complex type of psychotic mental illness characterized by thoughts that are uncoupled from reality. Huge gains in the effective treatment of individuals with the disease began in the 1950s with the development of the first generation of antipsychotic drugs. The medications allowed physicians to treat the “positive” effects of the illness (delusions and hallucinations) and, to a lesser extent, the “negative” symptoms (apathy). The second generation of antipsychotics – known as atypical antipsychotics (AAP) – began in 1990. These newer medicines have proven as effective in treating the positive aspects of the disease and more effective in combating the negative ones.
