The use of "ADD" and "ADHD" interchangeably is a common misconception that has historical roots. In the past, Attention Deficit Hyperactivity Disorder (ADHD) was categorized into different subtypes, including:
ADHD predominantly inattentive presentation (formerly known as ADD): This subtype is characterized by significant difficulties with attention, focus, organization, and forgetfulness, without the prominent symptom of hyperactivity.
ADHD predominantly hyperactive-impulsive presentation: This subtype is characterized by hyperactivity and impulsive behavior, but without significant inattention.
ADHD combined presentation: This subtype includes symptoms of both inattention and hyperactivity-impulsivity, which is the most common presentation of ADHD.
In the 2013 update to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the diagnostic criteria for ADHD were revised, and the term "ADD" was no longer officially used. Instead, the disorder is now referred to as "ADHD" across all presentations, and it is further categorized as follows:
ADHD, predominantly inattentive presentation (previously known as ADD): This corresponds to the earlier "ADD" subtype.
ADHD, predominantly hyperactive-impulsive presentation: Similar to the previous hyperactive-impulsive subtype.
ADHD, combined presentation: Reflects the presence of symptoms of both inattention and hyperactivity-impulsivity.
However, the older terms, particularly "ADD," have persisted in colloquial usage and continue to be used interchangeably with ADHD, leading to some confusion. Additionally, some individuals may still associate "ADD" with the inattentive presentation of ADHD.
To clarify, it's essential to use the correct terminology and recognize that ADHD encompasses different presentations, including both hyperactive-impulsive symptoms and symptoms primarily related to inattention. People with ADHD who predominantly experience inattentive symptoms still face significant challenges in their daily lives, and their struggles are no less valid than those with the hyperactive-impulsive presentation.
