Abstract
SummaryThe influence of parental age at birth, and parity, was studied in a series of 48 dyslexic boys. It was concluded that both increased paternal and maternal age contributes to a greater incidence of the condition. The similarity to the age distributions of chromosomal aberrations and some mutation defects suggests some genetic implication. The findings thus favour a biological rather than environmental element in the aetiology.
