Scientists discover way to reverse loss of memory

Scientists performing experimental brain surgery on a man aged 50 have stumbled across a mechanism that could unlock how memory works. Scientists are now applying the technique in the first trial of the treatment in patients with Alzheimer's disease.

Three patients have been treated and initial results are promising, according to Andres Lozano, a professor of neurosurgery at the Toronto Western Hospital, Ontario, who is leading the research. (Belfast Telegraph)
