Abstract:
In a descriptive analysis of 158 patients
with temporal lobe epilepsy, Taylor (1969) reported that the age of first seizure varied systematically as a function
of laterality and sex. We conducted inferential analyses of Taylor's original data which (1) provided
support for his proposal of disproportionate left hemisphere vulnerability to seizure onset in early life, but (2) failed
to provide evidence of sex differences in age of onset of unilateral seizures. Examination of these effects in
a larger sample of 844 patients drawn from the Bozeman Epilepsy Consortium provided some additional support for
findings from the inferential analysis. Specifically, the left hemisphere appeared more vulnerable to seizure onset
in childhood, this increased vulnerability extending to about age 5 years. Age of onset of seizures was not different
when males and females were compared. Thus, reanalysis of Taylor's original data as well as examination of
data from a larger, more contemporary sample suggest that seizure onset varies as a function of laterality, but not
sex. ( JINS , 1997, 3 , 428–434.)
