What is the difference between ADD and ADHD?

Thank you for this question. I find that this comes up often when exploring mental health and signs of ADHD. People often feel confused about the difference and similarities about language used for ADHD (Attention- Deficit/Hyperactivity Disorder). The difference between ADD and ADHD comes down to updated terminology used in the medical field.  The term ADD (Attention Deficit Disorder) is an outdated term that is no longer used in the medical community. This was a term that was previously used to describe individuals who experience symptoms of inattention and distractibility without the hyperactive or impulsive behaviors associated with ADHD (Attention-Deficit/Hyperactivity Disorder). People would often use the term, ADD, in replacement of the current medical term, ADHD - Predominantly Inattentive Presentation. 

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects individuals across the lifespan, influencing attention, behavior, and emotional regulation. ADHD can be diagnosed in children, or later in life as adults. Often referred to as an "umbrella term," ADHD encompasses a range of presentations and associated symptoms. 

ADHD is categorized into three primary presentations:

1. Predominantly Inattentive Presentation: Characterized by challenges in sustaining attention, following through on tasks, and organizing activities. Individuals may appear forgetful or easily distracted.
   
   
2. Predominantly Hyperactive-Impulsive Presentation: Marked by excessive fidgeting, restlessness, and impulsive actions. Individuals may struggle with sitting still and may act without considering consequences.
   
   
3. Combined Presentation: Involves a combination of symptoms from both inattention and hyperactivity-impulsivity. This is the most common presentation of ADHD.
   
   

The official diagnosis of ADHD is recognized in the most current version of the DSM-5-TR, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision. The DSM-5-TR is the most comprehensive and current resource for clinical practice available to mental health clinicians and researchers. The outdated term, ADD, is no longer present in the DSM-5-TR. 

Additionally, the DSM-5-TR recognizes "Other Specified" and "Unspecified" ADHD presentations to account for individuals who exhibit ADHD-like symptoms that don't fully meet the criteria for the primary presentations .

Despite the shift in terminology, many people continue to use ADD to describe ADHD, particularly the predominantly inattentive presentation. However, for clarity and accuracy, it's recommended to use the term ADHD when discussing the condition. 

I hope this helps to unravel any confusion about ADHD and its terminology. Thank you again for this important health related question.
