Researchers at an Arizona hospital are hoping a new device can slow down the progression of Alzheimer's Disease.
They started testing the Memor-E-M.
It has a cap and a transmitter which delivers radio-frequency energy deep into the front of the brain.
Patients will get two one-hour treatments a day for 60 days.
They they'll be tracked to see if it slows down their dementia.
The technique showed promise in mice. This is the first government-sanctioned test in humans.
