This seems to be a pretty common situation with PD. My Dad has the same situation and I try to have some daily activities built into the schedule and try to keep the same routine from day to day. Reading the daily news at the same time, exercising at the same time, having a snack with needed liquids to break up a nap, watching a favorite TV show or movie, phone calls to friends/family, etc.. I try to keep the daily sleeping at a minimum to allow for better sleep at night. One hour maximum unless he's had a bad night the night before. I try to only have about a 30 min. nap in the morning and afternoon and include other things to keep him busy and not resorting to sleeping too much. Once this became a routine it has really helped with the oversleeping during the day situation. He knows the routine and does much of it independently. There are days that revert back to the old problem - but for the most part things are better with a routine of daily activities to look forward to and participate in.

My father suffers from PD and recently was hospitalized for TIA. After bp was stabilized and tests were complete, he was still lethargic and his daytime sleepiness was more obvious as we were hovering. Drs did not want to release him in that condition and administered a double IV bolus. B4 they were finished he was lively, much like the man he was 10 years ago. When asked how we could duplicate that response, the drs said to keep him super hydrated, especially with water. Diminished appetite often accompanies diminished thirst in the elderly and you have to gently remind them to drink lots of water. They suggested keeping his pitcher or jug of water in the middle of the table so he could see how much he had consumed. We still have to remind him almost hourly to drink more. It does have an effect but not like the bolus!
