My husband has been at home since august not being able to cope with daily functions. sometimes he gets confused, he has memory problems simple daily tasks have become a challenge. there ipain in the left side of his body and he has trouble breathin?

Dementia: Although this could be secondary to medications, a sleep disorder, vitamin deficiencies, low thyroid, a chronic infection, depression, etc.; it might be instead a degenerative neuronal problem such as Alzheimer's or Lewy Body Disease. This does need proper investigation, and I recommend a visit with a local neurologist in the very near future.

Impairment: We don't know your husband's medical history. You have presented a number of concerning symptoms. Hopefully he has had a thorough medical assessment. What type of input were you looking for?
