What is attention deficit hyperactivity disorder
Attention deficit hyperactivity disorder is a condition in which the child is inattentive or hyperactive. Inattentive refers to kids having difficulty focusing as they are distractive in nature. Hyperactive are children who are inpatient. They cannot sit for long periods during school hours and often get up and walk in the classroom.
This disorder affects around 3% to 5% of school-age children. It is twice as common in boys as in girls.
No single cause has been identified for this disorder. It is caused by both genetic and environmental factors. Genes play a more important role.
Clinical featuresThe behaviors that are common in ADHD include
- Impulsive behavior
An inattentive child has trouble listening at school, is careless and easily distracted. They might also have difficulty staying focused and are often forgetful and loose things.
An impulsive child might hardly be able to wait for his turn in school while playing games. They may push or interrupt others.
Hyperactive children are fidgety and have trouble being quiet. They're often restless and do things like running around and climbing on furniture.
If the child has any symptoms of ADHD it is required that the parents pay close attention to the safety of the child. These children are more prone to accidents and hurt themselves frequently They tend to have conflicts with their peers and behave aggressively.
Diagnosis of ADHD is largely clinical based on the observed signs and symptoms. The following guidelines confirm a diagnosis of ADHD
- Symptoms occur in 2 or more settings, such as home, school, and social situations, and cause some impairment
- Symptoms significantly impair the child's ability of daily activities such as schoolwork, relationships with siblings and friends.
- Symptoms start before 12 years of age
- Symptoms have continued for more than 6 months.
In addition to signs and symptoms diagnosis might also involve a physical and neurological examination
