Caregiver101,
Uhhhhh ... nope. Doesn't sound right to me! Have you taken a look at her meds? Perhaps talk to a pharmacist or doc about her meds? Are the proper dosages being administered by you or others? I would certainly let her neurologist/doc know - get the doc's opinion. I think people with PD may tire a bit more easily .... but nothing like sleeping 40 hours. Has this behaviour started recently? Did anything else change around the same time - start/stop meds or change in dosage of existing med? Dietary changes? I assume you are the sole caregiver ... if not, are there other caregivers who could offer input? Sumthin just tain't right.
