Supports SBP monitoring in middle-aged adults; hypothesis-generating, should not change practice without RCTs.
Does higher cumulative systolic blood pressure exposure worsen cognitive function in middle-aged and elderly adults?
Greater cumulative exposure to systolic blood pressure over time is independently associated with worse cognitive performance, particularly in adults aged 60 years and older.
Liu et al. (2016) studied this question.
