My daughter is 11 years old. When she was 3 months old she suffered with seizure( epilepsy). Seizures were recurring for next one and half years. Her mental retardation  increased in that period acc to her doctors. After starting homoeopathic medicines we have seen lot of improvement. She started understanding, responding to small commands. Started  speaking  few words. Most importantly became calm n sits for long compared to earlier hyperactivity.
