A woman in North Carolina has been battling Alzheimer's for about a decade. Her daughter is pregnant but sadly she can't always remember. So the daughter started reminding her every time they saw each other.

The daughter posted the video because she thought her mom's reactions were cute and she wanted to spread awareness of the disease.

In the three-minute montage, Mom gets excited and claps her hands almost every time she finds out she's going to be a grandma. 

It's such a bittersweet reminder of what this disease does to loved ones.
