TENS stands for transcutaneous electrical nerve stimulation. This involves applying a mild electrical current through electrodes stuck to the skin. The treatment can produce a prickling sensation but is not painful. It is often used for pain control, for example during labour.
It is thought that electrical stimulation of nerves via the skin may cause chemical changes in the brain.
A number of studies have suggested that the use of TENS machines may produce short-lived improvement in some of the cognitive aspects of dementia, but the quality of these studies is poor and more evidence is needed.
