We learned that people with schizophrenia who regularly take the antipsychotic drugs prescribed to them live longer then those who do not. 

Psychiatrists have known for a while that antipsychotics can significantly reduce the number of debilitating hallucinations that plague many schizophrenics.  But there are concerns about the negative side effects of the medications themselves, such as increased risk of cardiovascular disease and diabetes. 

But a study from John’s Hopkins found that the positive effects of the medication outweigh any possible side effects.

After analyzing date collected from 2,132 adults with schizophrenia, they found that the patients who routinely took their medication with at least 90 percent compliance had a 25 percent lower risk of death, compared to those who were less than 10 percent compliant.  Also, each additional visit to a mental health professional further reduced their risk of death by 5 percent.
