Over the course of the study, 20% of the study’s participants developed dementia. They found that, while there was a mix of white and black individuals enrolled, white participants who admitted to consuming sleep aids “often” or “almost always” were 79% more likely to get dementia compared to the participants who rarely – or never – used them. Other interesting findings from the study was that the white participants were 10 times more likely to be taking trazodone, which is a pharmaceutical antidepressant also used as a sleep aid. They also commonly took Ambien, a sedative that helps induce sleep.
