Chronic insomnia linked to increased stroke and dementia risks

chronic insomnia stroke risk dementia neurological health mental health

A comprehensive review published in the journal ‘Sleep Medicine Reviews’ has identified significant links between chronic insomnia and various neurological and mental health conditions. Analyzing data from over 1.3 million participants, researchers found that individuals with chronic insomnia face a 26 percent higher risk of suffering a stroke and a 28 percent higher probability of hospitalization.

The study also noted associations between sleep deprivation and increased risks of dementia, depression, and suicidal behavior. While these findings highlight a strong statistical connection, experts caution that the research does not definitively prove that insomnia is the direct cause of these conditions.

Potential biological links include hypertension, which is a known stroke risk factor often associated with insomnia, and the brain’s ability to clear residual proteins, such as those linked to Alzheimer’s disease, during sleep. Researchers noted that the relationship between sleep and mental health is bidirectional, as sleep disorders can exacerbate emotional regulation issues and anxiety.
