Don't know where to post this

My grandma is 74, and she's been forgetting things...started with simple things like where she left her glasses or her purse...then she started forgetting if she had eaten, or if she had any water. Then we noticed she had issues remembering the rooms around the house, she forgets she has 3 daughters...

It always hurts when my mom asks her questions and she doesn't know the answer, she asks my grandma who am I, my grandma looks at me, then looks at my mom and says 'I don't know'.

There are no records of Alzheimer in my family, and I am not sure if I want to find out if she has it.

Thanks for reading.
