Some wearable devices like Google Glass have the ability to take hundreds of pictures a day from the user’s perspective, recording snapshots and memory of everyday life. For those with reduced cognition from conditions like amnesia and dementia, wearable cameras could help in both event recall and improvement to brain functioning and memory. Originally developed by a researcher at Microsoft who lost six months of memories due to a hit-and-run road accident, the SenseCam has been beneficial as a recall device for patients with amnesia and Alzheimer’s disease. A study found that patients with mild to moderate Alzheimer’s were able to recall approximately 85% of key factual details about events after two weeks of viewing SenseCam images every other day. After the SenseCam was replaced with a written diary, recall fell to 56%. After three months, the patients still had a recall of nearly 50% even without any image viewing. Two large trials are currently being conducted in Europe to further study the use of the wearable cameras and brain functioning.
Early research suggests that these devices can not only help those with amnesia and dementia recall important events, but may also be able to improve their memory abilities.
