ADHD is not a disorder that can be cured or healed. However, there are treatments and medications that are used to suppress the disorder.

There are 2 types of medications that are used to treat ADHD: stimulant and non-stimulant. Stimulant medication is the most prescribed medication to help treat ADHD in children since the 1960s. The medication targets a part in the brain called dopamine.

Some common stimulants that are prescribed are:

  • Amphetamine
  • Lisdexamfetamine
  • Dextroamphetamine

Non-stimulant medication affects a neurotransmitter called norepinephrine. This medication is only prescribed when a person does not respond to stimulant medication.

Aside from medications, there are several therapies that are also used in treating ADHD.

Behavior therapy is a form of therapy that helps to shape permanent behavior. It normally works by rewarding someone after doing the desired behaviors.

Additionally, psychotherapy (counseling) can also help people with ADHD to understand their situation better. Counseling also helps the patient to react better to stimuli.
