Scientists use light to prevent dementia

Researchers are exploring how to enhance brain activity through light stimulation in the hope of advancing a new strategy to prevent Alzheimer’s disease from developing.

The study is investigating new ways in which build-up of a protein toxic to brain cells, known as beta amyloid, could be halted with the use of light stimulation in areas of the brain which are particularly vulnerable to Alzheimer’s.

Scientists at the University of Strathclyde hope the 14-month study may lead to a new prevention strategy for Alzheimer’s in people at high risk of the disease, which is the most common cause of dementia.

Around 500,000 people in the UK have Alzheimer’s but currently there are no effective treatments or a cure, the university said.
