Dear Welcome to HCM We understand your concerns I went through your details. According to you your son is excellent in academics and can focus in all activities, can communicate very well and is highly analytical. That is certainly good for a 4 year old child. I don t see anything wrong in the behavior of the child. At the age of 4, any child is supposed to be a bit hyper mainly because of the playful attitude. You may search internet for the signs and symptoms of hyper activity and compare with your child. It s natural to wonder if ADHD (attention deficit hyperactivity disorder) could be the cause of your child s high energy. But just being hyper doesn t necessarily mean your child has the condition. Watch out for these other signs of ADHD: Does he interrupt frequently? Does he have trouble following instructions and organizing tasks? Is he forgetful? Is he impatient? Does he frequently speak out of turn? If your child has ADHD, these problems will happen over a long period of time, and usually at home as well as school. If you say Yes for three out of these questions, you may need to consult a psychologist for ADHD assessment and further guidelines.
