My dad won’t leave my mom alone as far as sex goes and he’s very demanding at times to go get some pills.
He can get aggressive with her at night and give her a hard time, this keeps her up all night.
My dad had a stroke over 23 yrs ago & recently had tested for beginning stages of dementia.
Good luck to you
What has your mom said to you about her thoughts on the situation?
Your Mom needs to discuss this with a good Neuro-psyc MD. Hypersexuality in conditions affecting the brain is quite common.
