Needed indoor treatment for a schizophrenic patient

My mother is a chronic schizophrenic patient .She has been under treatment for the last 16 years.In 2005 , she had a sub-dural heamorage and after which is has got dementia. As per doctors , her schizophrenia has become chronic and her activites has also become absurd which wasn't before haemorage.Above all she had started becoming voilent every time and attack anyone who is near to her.
            
We are looking for a place where she can be given proper indoor treatment and where she can recover in a better way.
           
Kindly suggest any facility to keep such patient and if yes what is the procedure for that .  
   
with regards,
