There is no need to paste a million leads all over your head and look like a multi-colored medusa.  If you have ever had an EEG the paste smells terrible and gets stuck in your hair.  It's just an awful experience.

That's why I was pumped to see a study using a wearable earpiece that can produce reliable information that may lead to a diagnosis of Alzheimer's.  It doesn't catch all of the information that a full EEG would but it does capture specific waves that can be used to establish a baseline picture of your brainwaves.

Seeing as we still don't know what causes Alzheimer's, early detection is an incredibly powerful tool when combating cognitive decline.
