Comparisons with siblings showed challenges were independent of family environment. ## Key findings Individuals with ADHD experienced more difficulties in education, careers, and social relationships. Results prove the condition's impact extends beyond childhood. ## Sibling factor Non-ADHD siblings from the same families showed typical functioning. This suggests challenges stem from biological/neurological factors rather than upbringing. ## Educational impacts Adults with ADHD showed significant differences in academic achievement and educational continuity. Childhood school struggles were found to persist into adulthood. ## Social outcomes The research revealed ADHD's lasting effects on friendship networks and romantic relationships. Social adaptation difficulties continue through adult life. ## Clinical significance The study emphasizes that ADHD interventions shouldn't be limited to childhood. Developing adult support programs is critically important for long-term success. ## Sources covering this story - https://www.reddit.com/r/science/comments/1v6zvgw/an_18year_study_found_that_children_diagnosed/ — --- _Summary written by Brifing from the original reporting.
