The research team compared the death rates of demented veterans based upon new outpatient exposures to various classes of psychiatric drugs.

Of the 12,821 patients who avoided exposure to psychiatric drugs, 18% died within one year.

Of the 10,615 patients who experienced treatment with antipsychotic drugs, death rates were consistently higher:

23% exposed to newer “atypical” antipsychotics died within 1 year
25% exposed to older antipsychotics died within 1 year
29% exposed to both (sequentially or concurrently) died within 1 year
