Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that manifests with inattention, impulsivity, and/or hyperactivity. It is developmentally atypical and remains relatively persistent over time, resulting in impairment across multiple settings and life activities. It is usually first diagnosed in childhood and often lasts into adulthood. 

ADHD occurs due to genetic and environmental influences with multifactorial contributors. ADHD is frequently comorbid with Oppositional Defiant Disorder (ODD) (40%), Anxiety Disorders (34%), Conduct Disorder (14%), Tic Disorder (11%), and Mood Disorders (4%). 

The diagnostic process includes ruling out any other potential medical or psychiatric explanations that better explain the current presentation. Physical health conditions such as iron deficiency anemia, lead poisoning, obstructive sleep apnea, epilepsy, and migraine, or psychiatric conditions such as post-traumatic stress disorder (PTSD), anxiety, depression, Autism Spectrum Disorder (ASD), and learning disabilities are some conditions which may manifest similarly to ADHD.  

Once the diagnosis of ADHD has been established, there are broadly two classes of psychopharmacological options to treat ADHD: psychostimulants and non-psychostimulants. According to the Multimodal Treatment of ADHD (MTA) study (1999), combined treatment of psychostimulants and psychotherapy demonstrates greater benefit than medication management alone for ADHD. Most side effects associated with psychostimulant medications are rare and temporary, often responding to adjustments in dosage or timing. Non-stimulant options that are generally well-tolerated include guanfacine, clonidine, and atomoxetine. Side effects to consider with alpha-2 agonists, such as guanfacine and clonidine, are sedation, blood pressure, and heart rate changes. Side effects are generally mild with the dosing range used to manage ADHD. 

Additional medication strategies can be considered to target commonly co-occurring anxiety, sleep problems, aggression, and tics. Psychotherapies may be considered as an additional treatment after optimization of medication. Behavioral therapies also may help with medication adherence. In addition to this, family therapy and motivational interviewing can have a role, especially in adolescents. If there are comorbidities such as ODD or CD, parent management training (PMT) and wraparound services can be considered.

Attention-Deficit/Hyperactivity Disorder (ADHD) Quiz

1. Which of the following percentages best approximates the global prevalence of Attention-Deficit/Hyperactivity Disorder?

2. What is the most common comorbid psychiatric condition in patients with ADHD?

3. Which sentence best summarizes the relationship between ADHD and Autism Spectrum Disorder (ASD)?

4. An 11-year-old patient with a psychiatric history of Attention Deficit/Hyperactivity Disorder (ADHD) and Generalized Anxiety Disorder (GAD) presents for an outpatient appointment. The patient has been stable on methylphenidate extended release (ER) 36 mg daily over the last 5 months with good symptomatic control of both symptoms of ADHD and GAD. The patient has no significant medical history and does not take any other medication. The patient has shown good growth and reportedly has good appetite. Vitals are within normal limits. The patient’s parent is inquiring if it would be appropriate to discontinue methylphenidate as symptoms of ADHD are resolved. What would be the most appropriate clinical decision?

5. Which one of the following is a contraindication for a psychostimulant?
