What is ADHD?

You may have heard of attention-deficit hyperactivity disorder (ADHD) or already know someone who has it. ADHD is one of the most common children’s mental health conditions, and many adults live with it, too.

ADHD is more than just the inability to focus; it can cause children and adults to experience disorganization, frustration, and problems with time management that can negatively affect self-esteem, and interfere with school, work, and personal relationships.

There’s no cure for ADHD, but treatment can help you manage the symptoms and experience a happy, well-balanced life. At Sulcata Psychiatry, Ms. Johnston provides highly personalized care in diagnosing and treating ADHD in children, teens, and adults. 

Ms. Johnston also treats children with oppositional defiant disorder (ODD), a condition that involves frequent anger outbursts, arguing, and defiance toward parents and authority figures.

What are the signs and symptoms of ADHD?

ADHD symptoms manifest differently based on a person’s age and the type of disorder they have. The three main types of ADHD are:


Inattention involves difficulty staying focused on a task, organizational problems, and forgetting daily activities like chores and errands.

A person with inattentive ADHD may not seem like they’re listening when spoken to directly and show poor time management, among other things.


Hyperactivity and impulsivity symptoms may include talking nonstop, interrupting others in conversations and activities, and being constantly on the go.

School-aged children with hyperactive/impulsive ADHD may have trouble staying in their seats during class or run around in situations where it’s not appropriate.


Combined ADHD involves symptoms of both inattentive and hyperactive/impulsive types.

How is ADHD diagnosed?

At Sulcata Psychiatry, Ms. Johnston offers cognitive testing with Cambridge Brain Sciences. The test is particularly helpful in diagnosing ADHD and other conditions that can cause similar symptoms, such as autism. Sulcata Psychiatry also offers Psychological Testing with a certified Diagnostician and Registered Behavioral Technician to establish an ADHD diagnosis and start the process of getting treatment or accomodations. 

At your first visit, Ms. Johnston performs a complete psychiatric evaluation to pinpoint your or your child’s specific concerns and target your mental health goals. She gets to know you as a whole person and treats you like a partner in your mental health care plan. She offers in-office pharmacogenetic testing with Genomind® to determine the best type of medication. 

How is ADHD treated?

Ms. Johnston’s goal is to provide you with the education, resources, and relief you or your child need to live a healthy and fulfilling life. Treatment at Sulcata Psychiatry is highly individualized and tailored to your unique needs. ADHD treatment may include: 

  • Medication management
  • Behavioral therapy or interventions
  • Accentrate® vitamins
  • Nutrition changes
  • Exercise, such as yoga
  • Changing sleep habits
  • School or Workplace Accomodations

Ms. Johnston treats the mind and body as a whole. She may recommend alternative therapies like the EndeavorRx® video game specifically for ADHD and bibliotherapy, which uses books to address mental health symptoms. She also uses Mehealth™ software to make it easier for parents, teachers, and health care providers to monitor ADHD symptoms and treatment.
