My mom really showed dementia when my dad had a heart attack July 2015. Neurologist did scans and said she had lost brain cells at a rate equal to her age. We have been down a rocky road. I have care in the home mainly in the day and weekends. I stay weeknights 5-8pm mainly. Mom has REALLY progressed in a worse manner. In the last month she has fell about 5 times due to balance. Mom mumbles more than speaks, eats differently by often sucking on her food. She has begun occasionally getting up at night too. I am perplexed. Her mumbling truly gets on my dads nerves. Has anyone seen progression this fast?
