Impact of PTSD and Obstructive Sleep Apnea on Cognition in Older Adult Veterans.

Posttraumatic stress disorder (PTSD) and obstructive sleep apnea (OSA) are highly prevalent and comorbid among older adult male veterans. Both PTSD and OSA are independently associated with cognitive deficits in older adults, but little research regarding the impact of comorbid PTSD and OSA among older adults exists. The current study aimed to examine the independent and interactive effects of PTSD and OSA on cognitive functioning in older adult veterans.
