ADD and ADHD are related, but they are not exactly the same.
In the past, Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD) were considered two separate diagnoses. ADD referred to individuals who primarily displayed symptoms of inattention, such as difficulty focusing, forgetfulness, and disorganization, but without significant hyperactivity or impulsivity. ADHD, on the other hand, included individuals who exhibited both inattentive and hyperactive-impulsive symptoms.
However, in more recent times, the diagnostic criteria for ADHD have been updated, and the term ADD is no longer used in clinical settings. The current diagnostic system categorizes ADHD into three subtypes:
Predominantly Inattentive Presentation (formerly ADD): This subtype involves significant difficulties with attention and focus but minimal hyperactivity or impulsivity.
Predominantly Hyperactive-Impulsive Presentation: This subtype includes prominent hyperactivity and impulsivity but relatively normal attention and focus.
Combined Presentation: This subtype involves a combination of symptoms, including both inattention and hyperactivity-impulsivity.
So, the term "ADD" has effectively been incorporated into the broader ADHD diagnosis as the Predominantly Inattentive Presentation. The term "ADHD" is now commonly used to encompass all three subtypes.
It's essential to note that the terminology may vary slightly depending on the diagnostic criteria used in different countries or regions. Nevertheless, the main distinction between ADD and ADHD is that the former typically referred to individuals with inattention as the primary symptom, while the latter includes both inattention and hyperactivity-impulsivity in various proportions.
