New technology hopes to drill down on brain injury detection
Alaska Dispatch

Traumatic brain injuries have been called the signature injury of the wars in Iraq and Afghanistan, affecting more than 155,000 men and women in uniform. But these traumas don't always have outward signs, making them difficult to diagnose. New technologies on the horizon may make testing for brain injuries faster, easier and more portable. These tests — which rely on objective physical measures of trauma, such as bleeding in the brain or markers in the bloodstream — could help detect at least some brain injuries in real time.

Implantable prosthetic could help prevent epileptic seizures
The Engineer
Share
A system that could electronically detect and prevent epileptic seizures is under development at the Massachusetts Institute of Technology. Researchers at the U.S. university say the system will rely on an implantable prosthetic, which will detect electrical activity associated with seizures and then use light to rapidly drive or silence key neurons in order to halt the seizure.

Stroke patients maintain benefits of robot therapy
Reuters
Share
Stroke patients who have the most trouble walking may see lasting benefits from using machines that move their legs to simulate walking, say Italian researchers. Their study, although small, is one of the first to observe a benefit lasting at least two years in a group of stroke patients who used the machines, which are sometimes employed in conjunction with traditional physical therapy.

Alzheimer's gene carriers may cut their risk with exercise
Bloomberg News
Share
People who are genetically susceptible to developing Alzheimer's disease may be able to reduce their risk with exercise, a study found. Carriers of the Alzheimer's gene APOE-4 who regularly exercised over a decade were 5 to 10 times less likely to have brain plaques linked to the disease than those with the gene who weren't physically active, said John C. Morris, senior author of the study published today in Archives of Neurology.
