We are dealing with a possible sleep problem. Mom is 80 and does not sleep well. The hallucinations came on suddenly and have lasted 2 months. They usually occur after a nap or in the evening. Two ER trips and 3 doctor visits have not helped or distinctly tied this to the dementia. She is on no medication except Xanax when she is very upset. We are waiting for an appointment with a new neurologist. The current neurologist thought maybe she had a sleep disorder and was in a persistent sleep state, but he didn't order any tests or sleep studies. She cannot stay at home now because of the hallucinations and sleepwalking, and often does not know my father. Otherwise her memory and function is good. We feel very let down by her doctors. Any suggestions on what type of doctor to see?
