Determinants of Long-Term Outcome After Concussion

This cohort study of U.S. veterans found that mild traumatic brain injuries occurring alongside psychological trauma are associated with long-term post-concussive symptoms and disability. The authors postulate that the traumatic context contributes to the development of post-traumatic stress disorder, which may in turn potentiate long-term sequelae.

Gabapentin vs. Duloxetine vs. Falls in Older Adults

This retrospective study examining fall risk among older adults taking gabapentin compared to duloxetine finds gabapentin users exhibit a markedly lower risk of fall-related visits at six months (hazard ratio = 0.52) yet finds no difference in the incidence of severe falls.
