Two Devices Treat Alzheimer's - Technology Review: Pharmaceutical companies developing Alzheimer's drugs have faced one hurdle after another. The most effective treatments are difficult to get into the brain, while those that show success in animals have yet to benefit humans.
Two startup companies aim to solve these problems by targeting the brain electrically rather than chemically. They're both using technologies that have proven successful for other brain disorders. One company plans to use deep brain stimulation, which has been used to treat tens of thousands of Parkinson's patients. The other hopes to find success with transcranial magnetic stimulation, a noninvasive approach used to treat depression and as a research tool to stimulate or inhibit specific parts of the brain.
