What does the acronym "ADHD" stand for?

The acronym "ADHD" stands for Attention Deficit Hyperactivity Disorder. This term accurately reflects the core characteristics of the condition, which includes challenges with attention, impulsivity, and varying degrees of hyperactivity. Understanding this terminology is essential for recognizing and addressing the symptoms and behaviors associated with ADHD.

The other choices do not accurately capture the nuances of the disorder. For instance, terms like "Deficiency" or "High" are not part of the established and widely accepted definition, which further reinforces why "Attention Deficit Hyperactivity Disorder" is the correct and recognized terminology in both clinical and educational settings. This understanding is crucial for effectively communicating and discussing ADHD in any relevant context, whether it be in treatment, support, or education.
