My 66 year old husband has been having a series of strange symptoms. He smells a strange smell. He is becoming more forgetful and forgot the dates of his children's birthdays. He is very impatient and irritable and tired all the time. His fine motor skills are diminishing-he has a hard time buttoning his coat. Ive been lookignup everythingfrom brain tumor to altzheimers. Who can I take him to see medically?
