SOUND STIMULATION CAN ALTER BRAIN WAVES AND HELP US HEAL!

 

Summary:

Recent research from the University of Surrey has revealed that sound stimulation can alter brain waves during REM sleep, a crucial stage for memory and cognition. This non-invasive technique, using advanced technology, could enhance memory functions by increasing the frequency of brain oscillations that slow down in dementia patients. This approach holds promise for innovative dementia treatments by targeting brain activity during sleep with minimal disruption to patients' lives.

Key Facts:

• REM Sleep and Brain Waves: REM sleep is vital for memory and cognitive functions, but brain oscillations slow down in dementia patients. Sound stimulation during REM sleep can increase brain wave frequency.
• Technological Innovation: Researchers employed closed-loop auditory stimulation technology, which adjusts sound stimuli in real-time to match brain wave phases. This technique demonstrated the ability to manipulate brain wave speeds.
• Study Details: The study, conducted with 18 participants, used high-density EEG to monitor sleep and apply auditory stimuli precisely. The results showed that sound stimuli could accelerate or decelerate brain oscillations based on their phase in the REM sleep cycle.
• Future Implications: This technique offers a potential new treatment method for dementia, providing a non-invasive, less disruptive way to enhance cognitive functions during sleep.

Dr. Valeria Jaramillo and Professor Derk-Jan Dijk from the University of Surrey emphasize that this non-invasive method could transform dementia treatment by improving brain function during REM sleep with minimal patient disruption. Dr. Ines Violante highlights the potential of this technique as a cost-effective and innovative treatment option, given the current lack of a cure for dementia.
