Neuropsychological deficits in adults with dyslexia.
Adults with severe dyslexia were compared with age-, sex-, IQ- and SES-matched controls on a neuropsychological and neuromotor test battery, and a contrast group who had recovered from dyslexia was also included. The severely dyslexic group was substantially impaired on tests of verbal fluency and learning, as well as on non-verbal temporal order judgements. These test scores were strong predictors of the degree of reading impairment, as was the rate of repetitive movement of the right hand and foot. The results suggest that adult dyslexia is not 'isolated', but is one expression of a widespread left-hemisphere dysfunction.
