Google Glass-like device could zap Alzheimer’s disease

Could alleviating Alzheimer’s symptoms be one day as easy as wearing a Google Glass-like device? It could, if new research led by the University of Otago (New Zealand) bears fruit.
The researches are focusing on stimulating humans’ sense of smell to prevent conditions such as Alzheimer’s disease associated with memory problems.
The olfactory system, or sense of smell, is known to be dysfunctional in the early stages of Alzheimer’s and Parkinson’s disease.
It is also shown that proper olfactory function can play a key role in regaining consciousness after brain injuries.
The Otago research centres around a wearable concept prototype — similar to Google Glasses — which produces small electronic pulses on the skin to stimulate the olfactory nervous system.
