It has been known for some time that individuals with schizophrenia develop progressive dementia later in life at higher rates than the general population. Some have argued that this association is a byproduct of the higher rates of chronic medical conditions or addiction in individuals with schizophrenia compared with the general population. Others postulate a biological association between schizophrenia and dementia. Ribe and colleagues1 add significantly to the literature on the subject in this issue of JAMA Psychiatry.
