ADHD is the most common psychiatric disorders of childhood which presents with inattention, hyperactivity, impulsivity that leads to academic underachievement or behavior problems.
There are three different types of ADHD depending on which types of symptoms are strongest in the individual. These are inattention, hyperactivity–impulsivity and combined inattentive/hyperactive impulsive subtype (combined ADHD).
No single factor has been identified as the cause of ADHD. ADHD is thought to be the result of complex interactions between genetic, environmental and neurobiological factors.

Two districts were chosen by simple random sample (Shibin Al-Qanater and Tukh). From each district two primary schools were included in the study; one rural and one urban by simple random sample. Each school was divided into strata reference to different grades then one class from each grade was chosen by simple random sample.
