A 70-year-old male with a history of Parkinson's disease presents with excessive daytime sleepiness and fatigue. His wife reports that he often wakes up gasping for breath during the night. What could be causing these symptoms and what are the recommended steps?
This patient's symptoms are indicative of Sleep Apnea, which can be more common in individuals with Parkinson's disease due to the associated muscle rigidity and other autonomic dysfunction. The next step should be a formal sleep study to confirm the diagnosis. Management typically involves CPAP therapy, but any changes in his Parkinson's disease medication regimen should also be considered with the help of a neurologist.
