Dear sir,I have a 13-year old sun who is moderate mental retarded and am trying to get better treatment. He is currently taking medicine called Respidal given to him by University Hospital here in Oman. We took him to NIMHANS Hospital in Bangalore for assessment but nothing has improved in his behaviour. He can not go to school neither has social  skills. Therefore I need your advice.Kind regards.Hamad.
Risperidal is Risperidone (atypical antipsychotic) available in 1, 2,3 & 4 mg strengths also witChatDoctorbination of trihexyphenidyl 2 mg to avoid extrapyramidal symptoms. It is usually prescribed in Mentally retarded patients. But you have not clearly mentioned the features as he may be a case of props Schizophrenia. If he is dull and lazy then a proper antidepressant may be added with Risperdal and if he is impulsive then one of mood stabilizers may be added in addition to Risperdal. Despite this medication, some nootropics may be added to enhance his memory and intelligence. I hope this helps you. Any queries are most welcome.
