Implanted device could curb cognitive decline for patients with Alzheimer's

Tools

Surgeons at Johns Hopkins implanted a pacemaker-like device into the brain of a patient with mild Alzheimer's, the sixth patient in a multicenter trial of the experimental therapy, according to MIT Technology Review. The device delivers electrical stimulation directly to the brain and early study results suggest it could improve memory and slow cognitive decline in patients with the disease. Deep-brain stimulation is already used to treat patients with Parkinson's, epilepsy, and obsessive-compulsive disorder, and researchers are exploring its use in other conditions, including obesity, according to the article.
