The researchers examined 20 comprehensive reviews from various countries. Additionally, a separate study released on September 9 in the journal "Neurology" identified insomnia as a "modifiable risk factor" for cognitive decline. In this study, 2,750 participants underwent regular neurological assessments and brain imaging while their sleep habits were evaluated. Findings suggested that insomnia is linked to a 40% increased risk of cognitive impairment. Notably, individuals with insomnia who increased their sleep duration or utilized sleep medications reported less cognitive decline.
According to the American Academy of Sleep Medicine, approximately 12% of Americans have been diagnosed with chronic insomnia. Experts emphasize the importance of maintaining a consistent sleep schedule. Dr. Diego Carvalho, an assistant professor of neurology and sleep specialist at the Mayo Clinic Center for Sleep Medicine, notes that sleep is crucial for eliminating waste and unnecessary synapses accumulated in the brain throughout the day. It is also vital for memory consolidation and overall emotional regulation.
To improve sleep quality, experts recommend minimizing phone usage and other distractions 30 to 60 minutes before bedtime, as well as establishing calming bedtime routines and ensuring the sleep environment is dark, quiet, and cool. If insomnia continues despite these strategies, consulting a doctor or sleep specialist is advised.
