SÖMNSTÖRNINGAR OCH ALZHEIMERS SJUKDOM

Sammanfattning: Alzheimer's Disease (AD) prevalence is 47 million in the world, 160,000 in Sweden. AD will increase by 70% in 50 years. AD cost is $7.9 trillion dollars in medicine and healthcare costs annually. Modifiable risk factors need to be mapped. Objective: Explore the relationship between sleep disorders and AD. Method: Searching PubMed and ScienceDirect for a literature review with 20 articles that were quality-reviewed. Result: Sleep-related factors that increase the risk of AD 1) Sleep disorders, sleep disturbed breathing, sleep apnea and insomnia. 2) The influence on cognitive ability, learning and memory showed correlation with sleep parameters. Sleep longer than 9 hours or less than 7 hours, daily naps longer than one hour were associated with increased AD risk 3) Other diseases and interfering factors, depression, cognitive impairment. Carriers of the APOE4-e4 gene with depression or cognitive impairment. IL-1b, a marker for inflammation, increases the risk of sleep disorders. People with clinician-verified depression and APOE-e4 were associated with a very high risk of AD, people with APOE-e4 and sleep disorders were associated with a high risk of AD. Symptoms of poor sleep that may be a sign of mechanisms are inflammation and tau / Ab accumulation as a sign of neurodegeneration. Conclusion: Sleep disorders, sleep parameters, disturbed REM sleep and genes are important for AD incidence. Programs to improve health literacy, control and treatment of sleep disorders and depression, limitation of risk factors, training in risk factors and sleep interventions. Interdisciplinary AD research needs to address the problem through transdisciplinary collaboration.
