My mom chewing and spitting out her food

I keep seeing my mom change these days. Her memory is on the decline. She says hi to me multiple times within a five-minute span. She has incontinence issues and often doesn't know whether she needs to relieve herself.

As of late, I've noticed that she chews her food and spits it out. I don't know if she has now forgotten how to swallow or if she physically can't swallow solid food.

She is fine with drinking fluids. The worst case scenario would be to blend her foods and have her drink shakes.

She will chew fruit and spit it out. It's more textured foods that she doesn't seem to swallow.

It has been interesting. I can see how frustrated my dad is with her. It's a challenge to say the least.
