ADHD in adults
ADHD is not just a childhood condition. Many adults live with persistent difficulty focusing, staying organized, following through, or managing impulses, often without ever having been evaluated.
Adult ADHD can look different from the childhood picture most people imagine. It often shows up as chronic disorganization, losing track of time, starting projects and struggling to finish, restlessness, or speaking and acting on impulse. Many adults reach us after years of wondering why everyday life feels harder than it seems to be for everyone else.
A careful evaluation looks at your full history, not just a checklist. ADHD shares features with anxiety, depression, and sleep problems, so getting the diagnosis right matters. Stimulant medications like Adderall work by increasing dopamine and norepinephrine activity in the brain circuits that handle focus, planning, and impulse control. In plain terms, they strengthen the brain's own braking and steering systems, which is why everyday tasks feel less effortful on them. Non stimulant options act on similar pathways in a different way. Treatment is individualized and any plan is made together with you.

Nasser et al. · Journal of Clinical Psychopharmacology · 2021
In 310 adolescents studied over 6 weeks, both tested doses of viloxazine ER improved ADHD symptom scores and overall clinical impression more than placebo. Sleepiness, headache, reduced appetite, nausea, and fatigue were the most common side effects, and fewer than 5 percent stopped treatment because of side effects.
