ADHD Specialists: Online and In-person Diagnosis and Treatment

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition that affects attention and self-regulation. It starts in childhood and often continues into adulthood. Adult ADHD is common and very treatable. In 2023, an estimated 15.5 million U.S. adults had a current ADHD diagnosis, about 6% of adults or one in 16, according to CDC’s 2024 report on ADHD in adults. About half were diagnosed as adults. Zellig Psychiatry provides ADHD care for teens and adults (12+) across Pennsylvania, so working with an ADHD specialist and care team is available by secure video statewide, plus in person in Wayne and Perkasie. You can book an adult ADHD evaluation and usually be seen within the week.

Symptoms of adult ADHD

Adults with ADHD usually notice symptoms in two areas: inattention and hyperactivity-impulsivity. Many adults struggle more with attention and organization than with visible hyperactivity, which often softens into inner restlessness by adulthood. The symptoms also look different at a desk job than they did in a fourth-grade classroom.

Common inattentive signs in adults:

• Trouble holding focus on tasks, reading, or conversations
• Careless mistakes or missed details at work
• Difficulty organizing tasks, managing time, and meeting deadlines
• Putting off tasks that need sustained mental effort
• Losing keys, phones, paperwork, or your train of thought
• Forgetting appointments, bills, and routines

Common hyperactive-impulsive signs in adults:

• A constant sense of inner restlessness or being “on the go”
• Trouble sitting through long meetings
• Talking over people or finishing their sentences
• Impatience with waiting or slow lines
• Acting, spending, or speaking on impulse

Everyone has days like these. ADHD is different in degree and duration. The symptoms are persistent, and they show up in more than one setting. They get in the way of daily life at work and at home.

What causes ADHD? Causes and risk factors

ADHD in adults comes mainly from genetics and brain development. Its heritability is around 74%, which means genes explain most of why some people develop ADHD and others do not, according to research on the genetics of ADHD. It tends to run strongly in families.

ADHD is a neurodevelopmental condition, which means it comes from differences in how the brain develops, beginning early in life. Those differences affect the brain systems behind attention and impulse control, including a set of skills psychologists call executive function: starting tasks, holding information in mind, managing time, and shifting between activities. In ADHD, those systems work less reliably. That is why a capable adult can still freeze at the start of a boring task or lose an hour without noticing. Exact causes are still being studied, and day-to-day stress can change how symptoms show up. The genetic signal, though, is consistent and strong, and ADHD has nothing to do with laziness or intelligence.

How adult ADHD is diagnosed

Adult ADHD is diagnosed through a clinical evaluation. There is no blood test or brain scan for it. A clinician reviews your history and how symptoms affect your daily life, then checks the findings against the DSM-5-TR criteria, the standard manual the American Psychiatric Association publishes for diagnosing mental health conditions.

For adults, that means at least five symptoms of inattention or hyperactivity-impulsivity, where children need six. Several symptoms must have started before age 12 and show up in more than one setting, such as work and home. They also have to interfere with daily life. A good evaluation also rules out other explanations, like anxiety, depression, sleep problems, or thyroid issues, that can mimic ADHD. Our adult ADHD evaluation page explains what the visit involves and how to book.

ADHD treatment options

Adult ADHD is treated with medication and therapy, alone or in combination, and most adults respond well. Medication is the first-line treatment for adults, according to the CDC. The two broad groups are stimulant medicines and non-stimulant medicines, and skills-based therapy like CBT helps many adults alongside medication.

Stimulants are the most studied option, and a 2018 network meta-analysis in The Lancet Psychiatry found amphetamines the preferred first choice for short-term treatment in adults. Non-stimulants such as atomoxetine and viloxazine give another route, per the National Institute of Mental Health. Which option fits depends on your health history and goals, so the specifics are a prescriber conversation. We do not adjust or recommend doses here. If you are under 18, our teen ADHD page covers care for adolescents. To start, our team reviews your goals and history during an adult ADHD evaluation and builds a plan from there.

What to expect: outlook with treatment

ADHD is a long-term condition, and for most adults it is very manageable with the right plan. Most do well. Treatment also lowers day-to-day risks: per the CDC, ADHD medication is tied to fewer unintentional injuries and lower rates of substance use problems. It is even linked to a reduced risk of death from unnatural causes. Yet about a third of adults with ADHD got no treatment in the past year, which is a big reason to get evaluated. Symptoms ebb and flow with stress and sleep, so care usually means periodic check-ins. Many adults find a workable plan after a few adjustments, then check in once or twice a year to keep it on track.

When to seek care

It is worth getting evaluated when ADHD symptoms get in the way of work and relationships, or wear on your well-being. Common signs it is time: deadlines slipping at work, or relationships strained by forgetfulness and lateness. Plenty of adults blamed themselves for years. They figured they were disorganized or lazy, when the explanation was often treatable ADHD. About half of adults with ADHD are first diagnosed as adults, so a late diagnosis is common and worth pursuing. ADHD also travels with other conditions, such as anxiety and depression, and a thorough evaluation looks at the whole picture. If you ever have thoughts of harming yourself, treat it as urgent and call or text 988.

Who treats adult ADHD? Psychiatrists, PAs, and ADHD specialists

Adult ADHD is treated by several kinds of clinicians: psychiatrists, physician associates (PA-Cs), psychiatric nurse practitioners, and psychologists who provide therapy and testing. An ADHD psychiatrist is a medical doctor focused on mental health who can diagnose ADHD and prescribe medication.

At Zellig, care is led by physician associates who specialize in psychiatry, working in collaboration with a psychiatrist. A PA-C (physician associate, certified) is a licensed medical provider who can diagnose and manage ADHD, including prescribing medication. You get a clinician who knows adult ADHD well. Titles vary. Some clinicians are described as an ADHD specialist or a psychiatrist for ADHD, and what matters is focused experience with adult ADHD and the time to build a plan with you.

Finding adult ADHD care near you in Pennsylvania

You do not have to live near a big-city clinic to get good ADHD care. You can start from anywhere in Pennsylvania, including rural areas where local ADHD prescribers are scarce. Zellig provides adult ADHD care to patients across Pennsylvania by secure video, so ADHD doctors near you are as close as your phone or laptop, anywhere in the state. We also offer in-person visits at two locations: Wayne (485 Devon Park Drive) and Perkasie (1259 Route 113). Telehealth has become a normal way to get ADHD care, and about 46% of adults with ADHD have used it for their care, per the CDC. The in-person locations are there if you prefer them, and most adults manage their ADHD care entirely by video. Most new patients can be seen within the week.

Insurance, costs, and telehealth across Pennsylvania

Zellig accepts nearly all commercial insurance plans in Pennsylvania. Before your first visit, our team can check what your plan covers. Telehealth visits are simple: you meet your clinician by secure video from home, and prescriptions go to your pharmacy electronically. Controlled ADHD medications come with extra federal and state rules for telehealth prescribing, and your clinician will explain what applies to you. Intakes run longer than a typical appointment, which matters for ADHD: a careful history is what separates it from look-alikes such as anxiety or a sleep problem. Follow-ups are shorter once your plan is set. If cost is a worry, ask our team about your options before your first visit. We can confirm your coverage and copay up front, so there are no surprises on the bill.
