persisting language disorder, severe literacy impairments, and significant deficits in theory of mind and phonological processing. Within the DLD cohort, higher childhood intelligence and language were associated with superior cognitive and language ability at final adult outcome. In their mid-thirties, the DLD cohort had significantly worse social adaptation (with prolonged unemployment and a paucity of close friendships and love relationships) compared with both their siblings and National Child Development Study (NCDS) control cohorts, matched on childhood IQ and social class. Self-reports showed a higher rate of schizotypal features but not schizoaffective disorder. Four DLD adults had serious mental health problems (two had developed schizophrenia).
