Brain 'pacemaker' tested to treat Alzheimer's

Scientists have created a pacemaker for the brain that could help in the fight against Alzheimer's.

The device deeply stimulates the brain with electronic pulses to keep neurons active. It does not use any drugs. Scientists say the procedure can slow memory loss and dementia.

Researchers at John Hopkins University have begun the process on their first patient. They hope to try it out on 40 patients over the next year.

The need for an Alzheimer's treatment is growing. Scientists believe the number of Alzheimer's patients could triple by 2050.
