Britain’s leading dementia research charity has released an app designed to personalize and simulate the experience of having dementia.  The FaceDementia app from Alzheimer’s Research UK temporarily takes over personal Facebook pages and temporarily erases important memories, mimicking how dementia affects the brain.  Users can watch their personal photos, important details and status updates disappear before their eyes while their real page remains intact.  Users can also watch short videos featuring people affected by dementia explaining what impact the symptoms, simulated by FaceDementia, have had on them or their relatives.  Alzheimer’s Research UK Chief Executive Rebecca Wood says, “Facebook’s appeal is that it can gather your friends and family and keep them close, with memories and contacts all contained within one space.  It also develops a diary of your life since you joined the site and documents your thoughts and musings during that time.”
