My son Harikrishna, who is nine and a half years old, faces Autism problem with traits of ADHD. Major issues with him was, too much of uncontrollable anger for irrelevant things. Biting, banging his head, pulling our hair badly and scratching is what he used to do continuously. We have been taking him for occupational therapy.Five months back my sister-in-law guided us to meet Mrs. Roma Biswas who is a sound therapist and she started treating him with the various sound frequencies. Nowadays, after his anger outburst, he realizes his mistake and becomes very emotional.
