Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is one of the most commonly diagnosed mental health disorders. People with ADHD are often unable to focus their attention on a particular task for very long, may be hyperactive or fidgety, and are generally unorganized and impulsive. Some people with ADHD mainly have problems maintaining attention, some are mainly hyperactive and impulsive, and some have problems in both areas. 


Persisting for at least 6 months:
Makes careless mistakes at work

Forgets tasks

Loses things

Has difficulty paying attention

Has difficulty organizing

Misplaces or has trouble finding things

Is easily distracted

Intrudes on others


Is Hyperactive

​Acts impulsive


People who are diagnosed with ADHD must have many of the above symptoms and signs to an impairing degree and occurring much more frequently than would be expected. Diagnosis of ADHD must be based on a thorough evaluation to exclude other possible causes of the difficulties.


Once a diagnosis is made, treatment options include behavioral therapy and medication. Up to 70% to 80% of people with ADHD respond to medication. The medication often results in rapid improvement in symptoms. This kind of medication helps curb impulsive and overactive behaviors, allowing for an increased ability to focus. ADHD medication is usually well tolerated.
