Just thought i would add a few links to the contrary about shortening life span. Anti-psychotics do have long term side effects, but if taken at lower doses, and the individual goes for regular checkups with there psychiatrist, and general practitioner lives can be extended. I am not defending the use of these drugs, but some people are in situations where they are there only option, and are necessary to extending there life.
People with mental illness are prone to heart disease, and diabetes, and that is the contributing factor to an early death.

They also have a tendency to not take care of themselves by smoking, over eating, and living sedentary lifestyles, along with no exercise. They also don't go for regular checkups with there general practitioner for there physical health, by overlooking there physical health do to there mental health.

I am tapering my antipsychotic because i have been misdiagnosed, not necessarily out of fear do to an increase in long term side effects like cardiovascular disease or metabolic syndrome, which seems to be caused by first generation antipsychotics, and high doses of second generation antipsychotics, along with lifestyles, and lack of attention someone with mental illness gives to there physical health.
