The main difference between Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD) is the presence or absence of hyperactivity.
ADD is an outdated term that was previously used to describe individuals who had difficulty with attention but did not display hyperactivity. However, in current diagnostic criteria, the term ADD is no longer used and is now included under the diagnosis of ADHD, which includes three subtypes:
1. Predominantly Inattentive Presentation (formerly known as ADD): This subtype is characterized by symptoms of inattention, such as difficulty with focus, organization, and follow-through, but without hyperactivity or impulsivity.
2. Predominantly Hyperactive-Impulsive Presentation: This subtype is characterized by symptoms of hyperactivity and impulsivity, such as fidgeting, restlessness, interrupting others, and difficulty waiting for their turn.
3. Combined Presentation: This subtype is characterized by symptoms of both inattention and hyperactivity-impulsivity.
It's important to note that ADHD is a complex condition and the symptoms can vary significantly from person to person. A comprehensive evaluation by a mental health professional is necessary to accurately diagnose and treat ADHD.
