Historical cause of death 1800s-1900s
What did general paralysis of the insane mean on a death certificate?
On a death record, general paralysis of the insane meant progressive paralysis with delusions and dementia, a common cause of death in asylums. In modern terms it usually pointed to neurosyphilis, the late stage of syphilitic infection. Asylum case books behind these certificates often survive, with photographs and family histories, though access rules apply to them. Expect it on records mostly 1800s-1900s.
Also written on records as: general paresis, GPI, paralysis of the insane.
