Like many others my early symptoms were attributed to getting older, stress, etc. Had REM sleep behavior disorder for years - first symptom, but minimized as "nightmares" initially. Onset of orthostatic hypotension exacerbated by heat and humidity in SC - initially attributed to low Carb diet and dehydration. Slowly progressive GI symptoms with slow gut, bloating, GERD and early satiety - all initially attributed to Irritable Bowel Syndrome. Then loss of sense of smell, difficulty with handwriting (smaller and smaller until I can't read my own writing), difficulty turning over in bed and getting out of bed and a shuffling gait with a tendency to lean forward. Over past year developing diminished voice volume and fatigue and weakness exacerbated by stress and heat. Most recently noted air hunger after exertion and lower extremity swelling - Echocardiogram pending to determine status of heart function. Current diagnosis: Autonomic nervous system failure and likely early Parkinson's ( though no significant tremor).
