Other top contenders include Lord Voldemort (master of Dark Arts, exceptional power) and Severus Snape (potions, Occlumency, Dark Arts).

Tom Riddle—aka Voldemort—was once one of Hogwarts' star students: brilliant in class and just as talented at causing trouble. Nicknamed a child prodigy, young Voldemort could move objects, communicate with and control animals, and “punish” those who crossed him—all without a wand.
While no official ADHD diagnoses exist in the books, fans often point to Fred & George Weasley, Luna Lovegood, and Nymphadora Tonks as characters exhibiting traits of ADHD, like impulsivity, hyperfocus, restlessness, and disorganization, though some also see Hermione Granger as potentially neurodivergent due to intense focus and social challenges.
