Attention-deficit/hyperactivity disorder (ADHD) was once referred to as attention deficit disorder (ADD). The term ADHD is used more often because it describes the inattention and hyperactive behavior often underlying the condition, the Mayo Clinic explains. The term ADD is sometimes used when the condition does not involve the hyperactive factor. The disorder usually begins in childhood but may not be diagnosed until adolescence or adulthood. There are three subtypes of ADHD that dominate the behaviors.
Hyperactive-Impulsive Behavior
The child may squirm frequently with the desire to leave his chair whether in the classroom or at the dinner table. The disorder may cause the person to always be on the go, running or disrupting the activities or conversations of others. There may be excessive talking and a habit of blurting out remarks when a teacher or an adult is talking. A child with ADHD have difficulty waiting for his turn to do something.
Inattentive Behavior
Children with a predominantly inattentive mood may be considered unmotivated. They have difficulty paying attention to details during school events or other activities and often make careless mistakes. Following instructions is hard for these children. They are often unable to complete tasks or chores and have difficulty organizing or arranging things. They don't seem to listen and are easily distracted. Forgetfulness is part of the disorder and the person often loses objects or possessions. Studies or homework are difficult because the inattentive child cannot stay focused on a subject. So the child dislikes doing it.
Combined Behavior
There are children who have a combination of hyperactive-impulsive and inattentive symptoms, according to Psych Central. The child may exhibit inattentiveness but also fidget or act restless at times. The actions of the child may vary between the hyperactive and inattentive symptoms.
Different Behaviors
The disorder can show up in varied ways for different people. Boys with ADHD are are more often hyperactive and girls are more likely to be inattentive, the Mayo Clinic says. Many children may exhibit some of these tendencies once in a while. There are children who have problems at school and act fine at home or with friends, or those who exhibit hyperactivity at home and are doing well in school. They are not suspected of having ADHD. They should also not be labeled with the disorder just because they are different from other children. But it should be a concern to parents and adults if the behavior lasts more than six months. If the behavior is disruptive to people around the child and is affecting the child's development, that may indicate ADHD.
