What Is ADHD?

ADHD is a neurodevelopmental condition that affects attention, executive functioning, and self-regulation. Symptoms may begin in childhood and continue into adolescence and adulthood, sometimes going unrecognized for years.

There are three primary presentations of ADHD:

Inattentive type, involving difficulty focusing and staying organized
Hyperactive-impulsive type, involving restlessness and impulsive behavior
Combined type, which includes symptoms of both

ADHD can affect school performance, work productivity, and relationships if not properly managed.

Symptoms Of ADHD In Adolescents And Adults

Symptoms of ADHD can vary by age and may present differently in adolescents compared to adults. In both groups, symptoms can impact daily functioning and long-term success.

Common symptoms include:

Difficulty concentrating or staying on task
Disorganization and trouble managing time
Forgetfulness and missed responsibilities
Frequent distractions or incomplete tasks
Impulsive behavior or difficulty thinking before acting
Restlessness or difficulty relaxing

In adolescents, symptoms may appear as academic struggles, difficulty following instructions, or behavioral concerns. In adults, challenges often involve work performance, time management, and maintaining routines.

How ADHD Is Treated

Effective ADHD treatment focuses on improving attention, organization, and impulse control through a personalized approach. Treatment plans are tailored based on age, lifestyle, and symptom severity.

At Johnson Psychiatry PC, treatment may include:

Medication management to improve focus and reduce symptoms
Individual psychotherapy to develop structure and coping strategies
Neuropsychological testing to support accurate diagnosis
Ongoing monitoring and treatment adjustments

This approach helps patients build practical skills while supporting long-term improvement.

Neuropsychological Testing For ADHD

Neuropsychological testing is an important tool for accurately diagnosing ADHD and understanding how it affects cognitive functioning. This comprehensive evaluation assesses areas such as attention, memory, executive functioning, processing speed, and problem-solving abilities. Unlike brief screenings, neuropsychological testing provides a detailed picture of how the brain processes information, helping to distinguish ADHD from other conditions with similar symptoms, such as anxiety or learning disorders.

At Johnson Psychiatry PC, neuropsychological testing is used to support precise diagnosis and guide individualized treatment planning. The results help identify specific strengths and challenges, allowing for targeted interventions that improve focus, organization, and daily functioning. This type of evaluation can be especially helpful for adolescents struggling academically or adults facing ongoing difficulties at work. By gaining a deeper understanding of cognitive patterns, patients receive more effective, personalized care and clearer direction for long-term success

Signs ADHD Treatment May Be Right For You

ADHD symptoms can be present for years without a clear diagnosis. Recognizing patterns in behavior, school performance, or daily responsibilities can help determine when professional evaluation is needed.

Signs that treatment may be beneficial include:

Ongoing difficulty staying organized or completing tasks
Academic struggles or declining performance in school
Trouble focusing during conversations, classes, or work
Impulsive behavior that leads to problems at school, work, or home
Chronic forgetfulness or missed responsibilities
Feeling overwhelmed by routine expectations

A comprehensive evaluation can provide clarity and help guide appropriate treatment options.
