An interesting new approach to treating Alzheimers:

A shunt implanted in the skull of a patient with Alzheimer's could be the first treatment that actually fixes what's broken in the brain rather than simply masking symptoms of the debilitating disease.

The device, called a CogniShunt, stops proteins suspected of causing the dementia associated with Alzheimer's from reaching the brain.

I don't know anyone with this disease but I've seen enough to know that it's devastating. I hope this holds promise.
