- Compared with those with no trauma, women who graded out as having probable posttraumatic stress disorder (PTSD) performed worse on psychomotor speed/attention and learning/working memory.
Why this matters
- There has been little previous research regarding PTSD and cognition in women.
- 14,151 in the Nurses’ Health Study II were completed the Cogstate Brief Battery, a self-administered online cognitive test.
- Funding: NIH.
- After adjustment for age, compared with women with no trauma, women with 4-7 PTSD symptoms had a worse performance in psychomotor speed/attention (b, −0.08 units) as well as learning/working memory (b, −0.10 units).
- The difference in learning/working memory was about equivalent to the effect of 4 y of aging.
- The study cannot prove causation.
- The study relied on self-reports.
- The Cogstate battery was conducted years after the assessment of PTSD.
