My husband also has very similar episodes of unresponsiveness. It is usually very near his next scheduled dose of carb/levo. I have found that administration of Parcopa, (an orally dissolving form of carb/levo) shortens the episodes miraculously when given with orange juice. His blood pressure during his episodes is low, 80’s/30’s. It also helps to lay him flat, & elevate his feet. He is up and going within 15 minutes, alert, and ready to go. His medications are Carb/levo 25/100 q 3hrs while awake, rotigitine 2mg patch daily, aricept 15 mg in divided doses of 10& 5 given with 10 mg of memantine twice a day in the early AM & after lunch.
We have also found that 20-30 minutes with a personal trainer on an ICare elliptical 2-3 times a week is very beneficial. We recently have added a 30 minute Bowen’s massage therapy twice a week which seem to help with mobility issues. His unresponsive episodes typically increase during episodes of Any physical stress due to constipation or infections ( ie. UTI, nephritis) or emotional stress due to upsetting life events. His diagnosis was LBD with Parkinsonism in 2012. He has no other chronic diseases.
