Why difficulties can stay hidden
High structure, family support, fear-driven overpreparation, academic strengths or a role that matches strong interests can mask impairment. When the environment changes, the same person may suddenly need much more self-directed planning.
Women and missed recognition
Systematic reviews describe under-recognition and late diagnosis in women, including social-emotional consequences before diagnosis. Recent work also highlights variation in female symptom presentation and the need to avoid male-stereotyped assumptions.
A late diagnosis still needs developmental evidence
The clinician is not looking for proof that somebody was diagnosed in childhood. They are looking for credible evidence that relevant patterns existed during development, even if nobody understood them as ADHD then.
