Clinical Information

ADHD, also known as Attention Deficit Hyperactivity Disorder (ADHD) is a chronic condition that affects one’s behavior, emotions, and ability to learn new things.
Researchers and doctors haven’t discovered the exact cause of ADHD. However, genetics, reduced dopamine levels, or a unique brain structure may play a role. ADHD usually affects children, but adolescents and adults may also be diagnosed later in life.
There are three types of ADHD: Inattentive, Hyperactive-Impulsive, and Combination. The inattentive and hyperactive-impulsive types have their own set of symptoms that are exclusive to the specific type. Meanwhile, a combination is a mix of the symptoms from the first two types.
Symptoms of the inattentive type are: making careless mistakes because of failure to pay attention, having difficulty sustaining attention, having poor listening skills, having organization difficulties, disliking active/tasks that require concentration, being easily distracted, and often forgetting daily activities.
On the other hand, symptoms of the hyperactive-impulsive type are squirming when seated, running/climbing/leaving during inappropriate situations, talking excessively, interrupting others, blurting out answers before completion of questions, and having difficulty quietly engaging in leisurely activities.
Diagnosing ADHD involves the practitioner interviewing the people the patient interacts with often, psychological tests, and observation of ADHD symptoms with scales and questionnaires.
To treat ADHD, a patient may combine medication - stimulants or non-stimulants - and therapy such as CBT, behavior therapy, or psychotherapy.

Synonyms Include:
