I'm caring for a client with Stage 5-6 lewey body PD dementia. He lives in his home with his able bodied wife. Yesterday he climbed the stairs trying to find his wife because she must be visible to him at all times. When he can't see her he becomes highly anxious. Climbing the stairs is a new behavior for him. He is a fall risk and he must be prevented from attempting to climb stairs. The Occupational and Physical Therapists ruled out a baby/pet gate since they feel that it would pose additional risk if the client were to try to climb over it. Any suggestions for barricading the stairs?
