Circadian pattern in cerebro vascular disorders.
Over the last decade, various studies have been reported to evaluate the circadian pattern of cardiovascular and cerebro-vascular diseases. The data from Indian population is lacking. We undertook this prospective observational study to evaluate the circadian variation in disorders like cerebro-vascular accidents and transient ischemic attacks. Total of 146 patients (events) were studied. Only 10 patients had TIA's. 55% had hemorrhage and 45% had infarction. The 24 hours period was divided into 6 equal portions of 4 hours each. The maximum events were seen between 4 am to 8 am and 12 noon to 4 pm (23.28%) each. Minimum events were seen between 12 midnight to 4 am 14/146 - 9.58%). The circadian variation in occurrence of cerebro-vascular disorders was present with two equal peaks.
