One of Parkinson's more insidious symptoms is fatigue. This is not your garden variety bone-tired. This is fatigue on a cellular level. Your body is working overtime to accomplish the simplest of tasks: Taking a shower, answering the phone, pouring orange juice. In addition, you may be coping with the combination of possible cognitive problems knows as "Parkinson's apathy". These problems include difficulty initiating projects, inability to follow complex instructions, short-term memory loss and difficulty in switching gears midstream.
You can fight Parkinson's disease apathy by exercising, trying to get regular sleep, taking short naps, and making sure you do not isolate yourself. Also ensure that you and your doctor are square on your drug regimen. The dishes still might not get done, but at least you will feel better.
