Which of the following best describes the clinical signs of ADHD?

The clinical signs of ADHD (Attention-Deficit/Hyperactivity Disorder) are characterized by patterns of inattention, hyperactivity, and impulsivity. The description of excessive fidgeting and talkativeness aligns closely with the hyperactivity aspect of ADHD. Individuals with this condition often exhibit behaviors such as being easily distracted, having difficulty remaining still, and frequently interrupting or talking excessively in conversations. These behaviors are core symptoms that help in identifying ADHD in both children and adults.

In contrast, the other options do not accurately depict clinical signs of ADHD. The inability to solve algebraic equations pertains more to specific learning difficulties rather than ADHD itself. Problematic social interactions can occur due to a range of reasons and are not exclusive to ADHD, making that option too narrow in scope. Lastly, saying that ADHD is purely a reading disorder does not capture the broader spectrum of symptoms associated with the disorder, as many individuals may have average or above-average reading abilities while still experiencing significant challenges related to attention and hyperactivity. Therefore, the portrayal of excessive fidgeting and talkativeness is the most precise representation of ADHD clinical signs.
