Pamela Phelps, who was represented by Cherie Booth QC, told the High Court she had been condemned to a life of 'temporary menial tasks' because a Hillingdon LBC educational psychologist had failed to diagnose her condition - thought to affect one child in every 10.
'I feel my whole life has been ruined,' she said after Tuesday's hearing. But she said she would use the o45,650 for special tuition and hoped to pass exams and eventually become 'rich and famous'.
A Hillingdon spokesman said: 'The council is disappointed that the court has found in favour of Pamela Phelps. We are currently considering the outcome with our insurers and as yet have not reached a decision with regard to an appeal.'
