Which of the following is NOT classified as a specific learning disability?

ADHD, or Attention-Deficit/Hyperactivity Disorder, is classified differently from specific learning disabilities. While it can impact academic performance, it is primarily characterized by patterns of inattention, hyperactivity, and impulsivity rather than specific deficits in learning processes such as reading, writing, or math.

On the other hand, dyscalculia pertains specifically to difficulties in mathematics, dyslexia relates to challenges in reading, and dysgraphia involves difficulties with writing. Each of these conditions directly affects specific academic skills and falls under the umbrella of specific learning disabilities, distinguishing them from ADHD. Thus, ADHD is not classified as a specific learning disability but rather as a neurodevelopmental disorder that can co-occur with learning disabilities.
