We present three cases of post-traumatic stress disorder (PTSD) symptoms associated with cognitive decline. Patient age ranged from 57 to 70 years old and all patients had war-related PTSD. In each case, the patient had a history of PTSD that was under fairly good control until the onset of cognitive impairment due to Alzheimer's disease or vascular or alcohol-related dementia. These cases suggest that neurodegeneration of memory pathways may dis inhibit symptoms of PTSD. (J Geriatr Psychiatry Neurol 2001; 14:17-20).
