The forgetfulness and confusion do point to the diagnosis of Alzheimer's disease at your age. The disturbed sleep pattern and feeling very tired during the day, as you describe it, is not a very common complaints from the patient of Alzheimer's disease. It may be related to some other issues. You need consultation from neurologist
or neuropsychiatrist for complete evaluation. The inability to seek specialist consultation is unfortunate and further course of investigation and treatment can be decided only after that.
