Yep, this is a big deal in gifted ed. "Twice exceptional" (gifted + very ADHD, to pick a common one) as they put it, is frequently encountered. Huge break-downs, depression, and disengagement when, eventually, the student has to actually start trying (which they may never have had to do before, at all, for potentially a decade or more of formal education) are common. Total failure to develop any kind of study habits is common, because, up to a point, they were never needed. Social problems due to having a brain, mental skills, language abilities, and knowledge, that are about half 7-year-old and half 25-year-old, are common (if not due to outright autism—see again, "twice exceptional").
