Treatment for sleep apnea is not a replacement for therapy and psychological care. However, sleep apnea treatment can alleviate difficulties with achieving uninterrupted REM sleep and stimulate its naturally restorative benefits to the brain. This promotes healthy mental function and may lessen the experience of mood disorders, as well as symptoms of anxiety, depression, fatigue, and stress. Furthermore, a healthy REM cycle has been linked to the flushing of waste proteins in the brain, potentially reducing your risk of developing dementia and Alzheimer’s disease.
