Both dehydration and overhydration can interfere with brain function in older adults. In a study, researchers used blood test data on 2,506 adults age 60 and older to determine how hydrated they were. Participants performed tasks to measure cognitive function. Among the women (but not the men), dehydration was associated with lower scores on tasks measuring thinking speed, attention, and memory. It’s not clear whether dehydration causes brain problems or whether people with brain problems drink less water. Meanwhile, 9 to 12 cups of water or other no- or low-sugar drinks per day are generally recommended for healthy women and men, respectively.
