Hello, In my opinion, since your son had already denied going to any psychologist or psychiatrist, do not force him. Compelling him to do it your way may lead to mood swings, drug/alcohol abuse or thoughts of suicide. This is a time when you have to be very patient, caring & loving. Since he is a good student you need not worry, first let him get well, let him calm down, relax & have confidence in his family members. The symptoms are indicative of developing ADHD, attention deficit hyperactivity disorder. But let him first get diagnosed, sometimes due to peer pressure, stress, hurt & anger; teenagers may show such restless, violent, impulsive behavior. With the passing of time, they may get fine & may not need any treatment. However, since he has shown such behavior it will be better that he gets clinically assessed & investigations like CT, PET & MRI be done to stay on the safer side. If reports are positive, treatment can be started at the earliest. Don t haste, give your son time. As a parent, you should talk openly with your son without pressurizing him for anything. Ask why he is disturbed & upset. Be supportive & accepting at all times. Other medical conditions that may cause violent behavior are Anxiety, Stress, Abuse (physical, verbal or sexual), ADD, ADHD or Bi-polar disorders. He may need to be treated with medications and therapy if there is no change in behavior in spite of maintaining a good family environment and loving care by the parents. If he gets out of control, get him admitted in a hospital & treated before symptoms get worse. Hope I have answered your query. Let me know if I can assist you further.
