The first symptom of ADHD in a child may be inattentiveness, impulsivity or hyperactivity – or all three. The doctors use these symptoms to classify ADHD children into three categories: Hyperactive-Impulsive, Inattentive, Hyperactive-impulsive-Inattentive.
Children suffering from hyperactive-impulsive ADHD are unable to sit still for more than a few moments. They get distracted very easily and often fidget around while the teacher is taking a class. They also have a very low attention span. They are impulsive in nature and tend to blurt out answers before thinking.
Most of these children can find difficulty in socializing due to their behavioral problems. However, they can be very demanding, and behave in an aggressive and violent manner on the playfield. At home they may resort to sudden outbursts of temper or indulge in arguments especially if they do not get what they want.
Inattentive ADHD children are a complete opposite to the Hyperactive –impulsive type. They are quieter and prefer to sit alone in a corner. Sometimes they even tend to be dull and listless in nature. In the class they are definitely inconspicuous. The biggest problem lies in their inability to grasp concepts and facts properly. They are preoccupied with their own thoughts most of the time. Their organizational and management skills are also poor. These children may also suffer from learning disorders.
There are fewer cases of children who suffer from all the three major symptoms of ADHD -- hyperactivity, impulsiveness and inattention. These children require immediate help because they may find daily activities challenging.
It is not necessary that all children who are impulsive or restless or inattentive suffer from ADHD. The symptoms become more apparent over a period of six months to a year. That is when it is essential to get a complete medical check up done.
