ADHD Subtypes

Attention-Deficit/Hyperactivity Disorder (ADHD) is a common and treatable neurodevelopmental disorder that affects children, adolescents, and adults. ADHD is characterized by challenges with attention, impulsivity, and hyperactivity. Typically, individuals with ADHD experience difficulties with executive functioning, self-regulation, and emotions. ADHD is recognized to include three distinct subtypes: predominantly inattentive type, predominantly hyperactive-impulsive type, and combined type. The inattentive type is characterized primarily by difficulty attending to tasks and details, which often leads to disorganization, forgetfulness, and difficulty staying focused. The hyperactive-impulsive type is identified by hyperactivity, impulsivity, and difficulty controlling emotions. Finally, the combined type includes a combination of both inattentive and hyperactive-impulsive type symptoms. ADHD subtypes are important to recognize and diagnose because they inform the type of treatment and management plan that may be most effective for each individual. Different interventions may be recommended depending on the subtype, and recognizing the distinct subtypes can help to tailor treatment to improve the overall outcome.
