Manipulating Brain Waves During Sleep With Sound

Sound stimulation can manipulate brain waves during REM sleep, a stage crucial for memory and cognition. Using advanced technology, researchers were able to increase the frequency of brain oscillations that slow down in dementia patients, potentially improving memory functions. The non-invasive technique could pave the way for innovative treatments for dementia by targeting brain activity during sleep. This approach offers hope for enhancing memory and cognition with minimal disruption to patients' lives.

Treatment Recommendations for People Who Act Out Their Dreams While Asleep

REM sleep behavior disorder, or parasomnia, affects more than 80 million people worldwide. The disorder causes sufferers to experience nightmare-like violent dreams. Sufferers act on their dreams while sleeping, often resulting in violent or dangerous sleep behaviors and injuries. Researchers propose new guidelines, including medical and pharmacological recommendations, to help curb symptoms of parasomnia and promote healthier sleep.
