In this issue of Neurology®, a team representing the Aspirin in Reducing Events in the Elderly (ASPREE) study reports the cognitive outcomes from low-dose aspirin (100 mg/d) therapy vs placebo in elderly individuals who were free of cardiovascular disease, physical disability, or diagnosed dementia.1 The trial enrolled 19,114 persons and followed them for a median of 4.7 years. Aspirin therapy did not reduce the number of cases of incident mild cognitive impairment or dementia nor benefit cognition. This result is in keeping with the conclusions from the main report of ASPREE in which no benefits occurred in the composite of death, dementia, or persistent physical disability.2 The current report explores the cognitive outcomes in greater detail and offers insights that may be valuable for future prevention studies.
