Will Medicare cover the cost of evening care for my parents?

My dad is ill, and mom is primary caregiver. I need some evening care for dad from about 10p,-8am so that mom can get some rest, as he's up all night.

Unfortunately, we don't have the finances to hire someone. Does medicare cover any of this type of care? I offered to come over one night a week, but mom wouldn't rest, because dad being old world, wouldn't let me take him to the bathroom, etc.

Mom and dad are both getting quited depressed due to their situation. And I'm afraid mom's health, mentally and physically, is declining at a very fast rate.

Any help or suggestions are greatly appreciated.!
