What is the primary difference between ADD and ADHD?

The primary difference between ADD (Attention Deficit Disorder) and ADHD (Attention Deficit Hyperactivity Disorder) centers around the presence and degree of hyperactivity. ADD is characterized mainly by inattentiveness symptoms, which can include daydreaming and a tendency to lose focus on tasks, without the intense hyperactive behaviors seen in ADHD. In contrast, ADHD encompasses a broader range of symptoms, including significant hyperactivity and impulsiveness in addition to inattention.

Choosing the option that states ADD is associated with daydreaming and that ADHD includes hyperactivity accurately reflects the definitions and characteristics of these disorders as recognized in current psychiatric classifications. Individuals with ADHD are more likely to exhibit behaviors such as fidgeting, difficulty remaining seated, and excessive talking, which are not typically associated with ADD. This highlights the distinct differences in symptoms and behaviors between the two conditions, making this option the most accurate representation of their primary differences.
