my mother has alzheimers and in a unit seems to be in the later stage but has recently started hallucinations and eyes wandering off. She seeems to be having difficulty breathing and one side of her face just today is drooping. The attending NP checked her today and said she just thought she was getting too much Ativan and did not have a stroke. She has had all Ativan and anti phsyc, meds held for the last 24 hours. My question is, can over use of Ativan cause any of her symptoms and do you think it could cause some sort of stroke. They also said her lungs were clear.
