BackgroundWe determined the pattern of clinically significant cognitive impairment (CI) among older veterans with posttraumatic stress disorder (PTSD) evaluated in a memory disorders clinic.
MethodsData were collected from 19 ethnically diverse veterans. Cognitive functioning in six domains (verbal learning, memory, attention, language, executive functioning, and information processing speed) was assessed.
ResultsThe majority of veterans (57%) demonstrated CI on a measure of single trial list learning, 44% exhibited CI on short delay memory for lists, and 31% exhibited CI in long delay memory for lists. CI on measures of memory for stories (14%) and executive functioning (6%) were less common, and none of the participants demonstrated CI on measures of attention, language, or information processing speed.
ConclusionsCI on measures of single trial list learning and memory for lists are common in older patients with PTSD evaluated in a memory disorders clinic and are likely to contribute to functional deficits.
