Hello Doctor. My father is suffering from a problem. While sleeping he used to throw his legs and hands unconsciously. He used to shout and talk. By this behaviour he had hurt himself and sometime my mother unintentionally. I gone through the internet and found that this similar type of problem is called REM SLEEP DISORDER (most probably). I want to know that whether this kind of problem is curable and how much success rate of cure is possible?As per that I would take an appointment for my father.
