My mother sleep walks now and cannot be "woken". She just wanders about mumbling and doing nonsensical repetitive things. She looks at us when we speak, but does not answer or take direction. This is the period when she hides money or keys or moves things she has hidden and then they are lost forever. During the day, especially after getting up or after a nap, she does similar things but is verbal, urgent, paranoid and seems awake. She moves and hides things, and rummages. She also will talk to us, but will not take directions. The two behaviors are similar. Is this sleepwalking both day and night? Or are these two different symptoms of dementia?
Has your mom had a sleep study done?
