Alzheimer's helmet therapy hope

An experimental helmet is being tested by scientists as a treatment for Alzheimer's disease.

It delivers low levels of infra-red light, which researchers at the University of Sunderland, believe may stimulate the growth of brain cells.

Tests in mice showed it improved learning ability and a study in humans is due to begin in the summer.

Current treatments for Alzheimer's delay progression of the disease but cannot reverse memory loss.

The infra-red therapy was first developed to treat cold sores.

But when researchers studied how it worked, they found it stimulated growth of cells and may have applications in other conditions.
