Transcutaneous Electrical Stimulation[TENS] For Alzheimer's Disease
   Transcutaneous electrical stimulation,abbreviated as TENS, is used to treat
pain. A tiny instrument delivers a small electric current through the skin to a
nerve and disrupts the transmission of nerve impulses. TENS has been found
useful for alzheimer patients. TENS improves the short term memory of patients
with mild alzheimer's disease, but does not improve memory in mid-stage patients
[206]. TENS also improves the altered circadian rhythms of patients, reducing
night time activity and promoting more restful sleep [207]. TENS is not widely
used as therapy and is still in the research stages.
