Watch a grandma's Alzheimer's 'disappear' for 5 minutes on her granddaughter's graduation day

Those whose lives have been affected by Alzheimer's know the pain of slowly losing a loved one long before they're actually gone. Dementia is a cruel diagnosis, and it's hard to overstate how difficult it is to endure someone you know well forgetting who you are. So when a family gets a glimpse of clarity, a moment of lucidity when their loved one remembers and is present with them, it's a gift beyond compare. That's why a viral video of a woman and her granddaughter on graduation day, when her Alzheimer's seemingly "disappeared" for five minutes, has left everyone a teary mess. @paige.lake...
