Reversible ischemic neurologic deficit (RIND) in a community: Rochester, Minnesota, 1955-1974.
This study defines the incidence, prevalence, and long-term prognosis of 120 patients with reversible ischemic neurologic deficit (RIND) in the population of Rochester, Minnesota. The average annual incidence rate for first episodes of RIND was was 16 per 100,000 population. The probability of subsequent ischemic stroke or RIND was six times greater in patients with RIND than in a normal age- and sex-matched population. RIND patients whose initial symptoms resolved within the first week were at greater risk for subsequent ischemic stroke or RIND than those whose symptoms resolved in the second or third week (p = 0.01). The survival of patients with RIND was not significantly different from that of the general population.
