A new Canadian study has found that older people with insomnia are at greater risk of developing memory decline and long-term cognitive impairment such as dementia. The researchers compared completed self-reported evaluations of sleep and memory and neuropsychological testing in several cognitive domains from 2019 and a follow-up in 2022. Participants who reported worsening sleep quality in that three-year interval also had greater odds of reporting subjective memory decline. All of these are considered risk factors for cognitive decline and dementia.
