Is Schizophrenia a Syndrome of Accelerated Aging? [PDF]

open access: yesSchizophrenia Bulletin, 2008
Schizophrenia is associated with a number of anatomical and physiological abnormalities outside of the brain, as well as with a decrease in average life span estimated at 20% in the United States. Some studies suggest that this increased mortality is not entirely due to associated causes such as suicide and the use of psychotropic medications.
