Attention Deficit Hyperactivity Disorder (ADHD) Practice Test 2026 – Comprehensive All-in-One Study Guide for Exam Success!

The predominantly inattentive type of ADHD is specifically characterized by significant issues with attention, making it the primary focus of the diagnosis. Individuals with this type may struggle with tasks that require sustained mental effort, have difficulty organizing tasks and activities, and may often forget daily activities or lose items necessary for tasks.

This type of ADHD does not encompass the hyperactive or impulsive behaviors that are often seen in other types. For instance, those with the combined type experience both inattentiveness and hyperactivity/impulsivity, which can lead to a wider range of behavioral challenges. The predominately hyperactive-impulsive type is characterized by excessive movement, fidgeting, and impulsive decision-making rather than attention deficits. Lastly, the term "situational ADHD" is not a recognized type of ADHD in clinical practice or the DSM-5, and thus does not accurately describe any officially classified subtype. This delineation of symptoms makes the predominantly inattentive type distinct and highlights its core characteristics.
