Spouse, 93 w/1st stage dementia, has had PD for some years, but since the dementia dx has been falling asleep while eating, using toilet, just sitting reading or watching TV, etc. Is this a PD symptom? Other medical conditions: CHF, HBP, Hyperlip, BPH, spinal stenosis. Other symptoms include chronic leg swelling, mobility, urinary incontinence, etc.
