You S, et al. - For this research, the physicians determined the frequency and predictors of cognitive impairment among participants of the pilot phase, Intensive Blood Pressure (BP) Reduction in Acute Cerebral Hemorrhage Trial (INTERACT1). Significant cognitive impairment was observed in one-third of patients early after intracerebral hemorrhage (ICH). This was more frequent in the elderly, females, those with prior ICH, and more severe initial neurological deficit and with persistently high early systolic BP.
