Twice-daily brain zaps may boost ‘rewiring’ & functioning in Alzheimer’s

Posted on by

A study found that twice-daily non-invasive electrical stimulation improved brain functioning in patients with Alzheimer's disease

Research has found that non-invasively applying a mild electrical current to the brain twice a day for six weeks improved cognitive functioning and plasticity, the ability of the brain to ‘rewire’ itself, in patients with Alzheimer’s disease. The treatment may be an effective way of reducing – or even reversing – the effects of the condition.
