The New York Times (5/17, Span ) reported a study found that “over five years, study participants’ performance on cognitive tests” after a transient ischemic attack “drops as steeply as it does among victims of a full-on stroke.” Researchers said, “If you have one stroke or one T.I.A., with no other event over time and no other change in your medical status, the rate of cognitive decline is the same.” They observed that “even if the symptoms resolve – typically within 15 minutes to an hour – T.I.A.s set people on a different cognitive slope later in life.” Furthermore, after a TIA, “neurologists put the risk of a subsequent stroke within 90 days at 5 percent to 20 percent, with half that risk occurring in the first 48 hours.” The study was published in JAMA Neurology.
