My father aged 89 years is showing symptoms of dementia in Parkinson's. He was diagnosed BPH 3 years ago. He is hard of hearing also, can hear from right ear only. Recently got treatment for a pressure bed sore on foot which got infected. He was given anti biotic injections and orally also, was in hospital for 12 days. Hospital discharged him saying his vitals are fine and his brain as such is also not seems shrinked much so no need to go for MRI OR SCAN. They started arip tablet to stop the progression of dementia, no other medications advised. We found his mental and physical condition deteriorated Before hospitalisation he was moving a bit with help climbing stairs also and was responding on asking anything. Now he is totally immobile keep his legs folded most of the time, keeps upper hands stiff glued to body and resist even dressing or see hanging diapers. He does not reply most of the time. Any medicine in homeopathy to improve his condition?
