Hi auntsissi ,
I am really sorry to hear about your father’s condition .Itching could occur after stroke if the stroke is in the thalamus area of the brain which receives the sensory information of pain , touch , temperature , pressure and other sensations from all over the body . The onset may be from days to weeks after the stroke . Topical therapy with moisturizers and emollients helps alleviate the itching . Treatment with amitriptylene 50 mg a day results in resolution of the itching . Some patients respond to Carbamazepine also. Ativan is an antianxiety medicine . First of all he needs a drug like Amitryptylene or Levocetrizine to control the itching . He will be able to sleep well once he gets relief from itching . Please consult your physician and dermatologist to discuss these treatment options if the present medications are not providing relief from the symptoms .Hope this helps you . Take care and regards !
