Canadian scientists say that deep brain stimulation (DTS) could reverse the effects of Alzheimer’s. Although it’s far too early to describe their results as a ‘cure’, tests show that the technique can reverse the expected decline in the brain’s memory hub.
DTS works by applying an electrical charge directly to parts of the brain. The precise mechanism by which this reverses the effects of Alzheimer’s is not clear, but some believe that the electrical charge could disrupt a kind of ‘stalled’ electrical rhythm that characterises degenerative brain diseases.
There are also hopes that the DTS approach could be used for other things, potentially not only dealing with conditions such as Tourette’s syndrome but possibly even helping ‘healthy’ people to improve their memory and coordination.
