My husband was diagnosed 2yrs ago with mixed dementia. He went through a patch of being very sleepy all the time but that's passed now to be replaced with the equivalent of ADHD! He doesn't seem to be able to sit still for very long during the day. I'm finding it completely exhausting just being with him. I wondered if anyone else had experienced this and if there's any medication for it? He's not on any meds as they wont give him anything due to him having a bowel op and him having a heart murmur. Any suggestions?
