I think if i was a child today ,with more emphasis on child/adolescent mental health, i would have been flagged up for psychiatric/psychological intervention much earlier.
As it was the only childhood assessment i had which i have no memories of(was 6) was at Great Ormond street and ruled out, as it was then called,that i was spastic. My teachers at my school in Thailand had expressed concerns over difficulties i had. Nowadays i think aspergic/dyspraxic/non verbal/visuospatial problems/traits would have been picked up but my assessment was in the early 60s.
After that i flew under the radar with not much attention paid to gradually worsening academic performance and the long standing social problems by parents and schools. In their eyes that was just the way i was.
Back then there was much less recognition of specific problems in otherwise intelligent children/adolescents. Nowadays there is the phrase 'gifted and learning disabled' to show that intelligent children/adolescents can have problem areas.
