Other Research
The most common treatments for ADHD include stimulants like methylphenidate and amphetamines, and non-stimulants such as atomoxetine and guanfacine. Stimulants primarily work by increasing the levels of dopamine and norepinephrine in the brain, which helps improve attention and reduce impulsivity and hyperactivity. Non-stimulants like atomoxetine, a selective norepinephrine reuptake inhibitor, also increase norepinephrine levels but do so without the same stimulant effects. Solriamfetol, a dopamine and norepinephrine reuptake inhibitor (DNRI), similarly enhances the levels of these neurotransmitters. This is crucial for ADHD patients as it helps regulate attention, behavior, and executive function, thereby alleviating core symptoms of the disorder.
