My Mom was in great health when she turned 70. Good husband, family, finances. At 70 she decided she was "too old" to do anything or live life anymore. She essentially became a shut-in, started drinking wine all day and stopped eating. Her personality has changed - she has become nasty and negative and has no interest in her family or world. She won't even watch TV. She is now on day 4 in the hospital - she can't walk or stand. They are giving her IV fluids and vitamins. No signs of dementia other than the personality change. She seems resigned to being helpless, almost welcoming it. My dad is her primary caregiver and I am doing all I can to help. Making no sense to me whatsoever. I don't think my dad can take care of her much longer. I'm afraid she will linger in a nursing home for many years. Her own mother lived to 96.
