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.
