Thirty seven adults with a three generation family history of dyslexia
and a strong personal history of reading/spelling problems were admin
istered a psychoeducational battery to confirm the diagnosis of dyslex
ia. Males were not disproportionately represented in the dyslexic samp
le although they exhibited a more severe profile of reading impairment
relative to females. Severity of dyslexia is discussed as a possible
mechanism of the reported higher prevalence of dyslexia among males.
