Could enhancing brain activity help to prevent Alzheimer’s?

Light shone in the brain to alter brainwaves

A novel approach to enhancing brain activity is being explored by researchers at the University of Strathclyde, in a bid to prevent Alzheimer’s Disease taking hold.

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.

The study may ultimately lead to a novel prevention strategy for Alzheimer’s in people at high risk of the disease. The 14-month study is being funded by the charity Alzheimer’s Research UK, the UK’s leading dementia research charity.

Alzheimer’s disease 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.

Dr Shuzo Sakata, a Senior Lecturer in Strathclyde Institute of Pharmacy and Biomedical Sciences, is leading the study. He said: “The lack of a cure for Alzheimer’s disease means there is an urgent need to develop new, innovative approaches to combating it.

“We have known for a long time that the beta amyloid protein is toxic to brain cells; it has recently been found that manipulating the activity of neurons can reduce the protein in some regions of the brain. But what is not well understood is how it can be used to do this across many brain regions at the same time.

Brainwaves

The pre-clinical research will be focused on a brain area which communicates with many other areas and is among those most affected by Alzheimer’s. It will discover whether activating neurons in this brain area, using light, can enhance fast brainwaves which are impaired in people with Alzheimer’s.

The study will investigate whether such enhancement of brainwaves can reduce build-up of the toxic protein in a range of areas of the brain.

The research has received a grant of £50,000 from Alzheimer’s Research UK.

Dr Carol Routledge, Director of Research at Alzheimer’s Research UK, said: “Dementia is one of our greatest medical challenges, but research has the power to improve our understanding of the condition and deliver effective new treatments. With around 70,000 people in Scotland living with dementia and no new treatments in over a decade, pioneering projects such as these offer real hope in the fight against dementia.

“It is paramount that we can support researchers as they add crucial pieces of knowledge to our growing understanding of the diseases that cause dementia.”
