Alzheimer’s disease could be reversed by shining light directly into the brain through the nose and skull, scientists believe.
The first major trial to see if light therapy could be beneficial for dementia has just begun following astonishing early results which have seen people regain their memory, reading and writing skills, and orientation.
If successful it would be the first treatment to actually reverse the disease. So far, even the most hopeful drugs, such as Biogen’s aducanumab, have only managed to slow the onset of dementia, and many scientists had given up hope of reversing brain damage once it had already happened.
