New Study Links Insomnia and Chronic Stress to Increased Alzheimer's Amyloid Accumulation

Researchers at Karolinska Institutet, publishing in the Journal of Neurology, found that a lifetime of stressful events was associated with greater amyloid accumulation in the brain, but only in individuals who also reported moderate to severe insomnia symptoms. This suggests that treating insomnia, especially in stressed older adults, could be a crucial strategy for dementia prevention.
