Who can I turn to for help with my deaf, blind mother-in-law? She has dementia and is currently in an assisted living facility.

I searched “deaf blind dementia” on Google and got a lot of hits on this forum.

Look up “fidget blankets” on Amazon. They have zippers and bells and things sewn on, like this. https://www.etsy.com/listing/526400812/fidget-quilt-activity-blanket-busy

You may also get her a joy for all toy cat or dog for tactile stimulation.

Not much I would say. Poor lady. Call your County Disabilities Dept and see if there is help.
