My DH is beginning to get up later, take hour long naps and go to bed earlier than usual. He had a complete physical and he is very well physically. I have read that this is not unusual since mental activity is exhausting for people with Alzheimer’s. Just wondering if there is anything more I can do to give him more energy. Protein bars? Supplements? Foods? I just don’t want him to sleep away what is left of his best life. Thank you.
