There's no cure yet for Alzheimer's, but identifying the risk of developing symptoms as early as possible means that preparations and mitigations can be put in place.
The headband used in the study.
In trials involving 205 older adults, the researchers used the headbands to detect neural events including theta bursts, sleep spindles, and slow waves. These are all types of brain activity associated with memory processing during sleep.established a link between poor sleep quality and Alzheimer's, but the details have been difficult to tease out. It's not fully clear how sleep influences Alzheimer's progression, or how the disease can affect sleep in return.
Here, the team identified changes in neural patterns during sleep that could be related to the build up of theThe scientists discovered links between certain patterns and signs of Alzheimer's. "What we found is these abnormal levels of proteins are related to sleep memory reactivations, which we could identify in people's brainwave patterns before they experienced any symptoms,"The researchers also found that decreased intensity in one pattern of activity correlated with very early mild cognitive impairment.
Headbands like this one are some way off becoming commercially or even clinically available, not least because it's still not certainHowever, an easy-to-wear device that people can put on in their own homes could potentially make a major difference to early Alzheimer's detection, as well as giving researchers a ton of new data on the relationship"We are just scratching the surface with this work, paving the way for affordable and easy-to-use devices to monitor brain...
