Pediatric and adult ADHD treatment in

Tribeca, NYC

ADHD treatment that accounts for the whole person

We offer a radically different kind of ADHD treatment - the one that sees you and understands you for who you are.

Attention-deficit/hyperactivity disorder looks different at every age. Whether your child is struggling in school or you are an adult who has spent years wondering why focus feels impossible, an accurate diagnosis and individualized treatment can change the trajectory.

Inattention

  • Difficulty sustaining focus on tasks or play activities

  • Frequently loses materials — backpack, homework, belongings

  • Does not follow through on instructions or complete tasks

  • Easily distracted by external stimuli or unrelated thoughts

  • Avoids tasks requiring sustained mental effort

Hyperactivity / Impulsivity

  • Cannot remain seated in structured settings

  • Runs or climbs in situations where it is inappropriate

  • Talks excessively; interrupts or intrudes on others

  • Difficulty waiting for a turn

  • Acts before thinking through consequences

Emotional and relational

  • Rejection-sensitive dysphoria; disproportionate responses to criticism

  • Relationship strain from forgetfulness and disorganization

  • Shame, chronic underachievement, and internalized self-blame

Daily functioning

  • Difficulty managing finances, appointments, and paperwork

  • Chronic disorganization of home and workspace

  • Sleep dysregulation — delayed onset, difficulty rising

  • Underemployment relative to education and cognitive ability

  • A thorough clinical interview covering developmental history, current symptoms, functional impairment across settings, and ruling out alternative diagnoses. For children, input from parents and, when relevant, teachers is incorporated.

  • Before any treatment decision, we ensure patients and families understand what ADHD is neurobiologically, how it manifests in this particular person, and how various psychosocial factors influence the pressentation.

  • Treatment is not one-size-fits-all. We discuss medication, behavioral strategies (including executive functioning coach) , psychotherapy, school or workplace accommodations, and any co-occurring conditions that need to be addressed.

  • Regular follow-up to assess treatment response, adjust medication if needed, and adapt the plan as circumstances change, particularly important during developmental transitions.

Work and attention

  • Chronic difficulty sustaining focus on low-interest tasks

  • Hyperfocus on engaging work at the expense of other priorities

  • Persistent lateness, missed deadlines, and dropped commitments

  • Rereads the same passage repeatedly without retention

Internal restlessness

  • Hyperactivity becomes internal — racing, crowded thoughts

  • Difficulty relaxing, being still, or tolerating quiet

  • Impulsive spending, decisions, or statements

  • Interrupting conversations; finishing others' sentences

Our Approach: Evaluation and treatment, integrated

A diagnosis is only useful if it leads somewhere. Dr. Thein's approach combines a rigorous diagnostic process with treatment planning that reflects the full clinical picture — including co-occurring conditions, family context, and individual goals.

Emotional

  • Rejection-sensitive dysphoria becomes more pronounced

  • Increased vulnerability to co-occurring anxiety and depression

  • Low self-esteem compounded by years of underperformance

Executive function

  • Poor planning for tests, applications, and long-range goals

  • Difficulty managing complex schedules without external scaffolding

  • Difficulty transitioning off preferred activities

  • Working memory deficits interfere with multi-step tasks

 

Adolescents

Academic

  • Difficulty managing long-form projects and deadlines

  • Underperforms on tests despite apparent knowledge

  • Cannot sustain focus through lectures or independent work

  • Forgets assignments or fails to submit completed work

Behavioral

  • Increased risk-taking — driving, substances, impulsive decisions

  • Difficulty tolerating boredom; stimulation-seeking behavior

  • Excessive screen use as a form of self-regulation

  • Procrastination and last-minute work as a coping pattern

ADHD by developmental stage

The core symptoms of ADHD manifest differently depending on age, context, and individual temperament. A general overview of how it can present is illustrated below.

What is ADHD?

ADHD is one of the most common and well-studied psychiatric diagnoses, yet it remains widely misunderstood. It involves differences in how the brain regulates attention, impulse control, and activity level and those differences are neurobiological, not a matter of willpower.

ADHD is diagnosed across three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined. The inattentive type is frequently missed, especially in girls and adults, because it does not look like the stereotypical picture of a child who cannot sit still.

ADHD frequently co-occurs with anxiety, depression, learning differences, and sleep difficulties. Effective treatment addresses all of these together.

Adults

Children

Emotional and social

  • Low frustration tolerance and mood dysregulation

  • Emotional reactions out of proportion to the trigger

  • Difficulty reading or responding to social cues

  • Peer conflict stemming from impulsive behavior

Academic impact

  • Underperformance relative to measured intelligence

  • Inconsistent work quality across days or settings

  • Difficulty initiating tasks without external prompting

  • Poor time management on assignments and tests
