My grandmother got dementia this past year and for months I was scared to go up to visit her because she felt distant, and I didn't really know how to talk to someone with dementia.
Eventually I got over myself and started visiting her a couple times a week. Often she wouldn't know who I was, but her face always lit up whenever she saw me that it didn't matter in the end.
One day, I was helping her walk to her room to lay down, when she looked at me with such alertness in her eyes and started asking me all about how my job was doing, stories she remembers about me, and telling me how she feels in her day to day. We talked for almost an hour like this before she lapsed back into a more confused state.
Looking back, I realized that must have been the most I talked to her in one sitting and although that filled me with a lot of regret and guilt, I am so grateful I got the chance to connect with her before it was too late.
She's in a nursing home now, and doesn't recognize me anymore, and that's okay.
