Types of ADHD Medication: ADHD medications can be broadly categorized into two main types: stimulant medications and non-stimulant medications. Each type has its own set of medications, and the choice often depends on the individual's specific needs. Stimulant Medications : Stimulant medications are the most commonly prescribed for ADHD and are generally the first line of treatment. They work by increasing the levels of certain neurotransmitters in the brain, which helps improve attention and impulse control.
