  • Subjects with hippocampal ratios⩾1.09 are shown inbold typeface; ECC scan=time in days between convulsion and MRI scan; ECC dur=duration of convulsion; FH=family history of epilepsy; Fever=presence of fever on arrival at hospital; Focal =any focal features (R, L = right or left hemiconvulsion) or whether generalised (G); Recur=recurrence of seizures in 24 hour period; HT=head turning; N=normal; Csn=caesarian section; Pro=prolonged labour; Bld=vaginal bleeding during pregnancy; Ind=induced labour; Patient 3 (in italics) was excluded because of clinical and EEG evidence of benign childhood epilepsy, and the data were not included in means and SD calculations for the “patients with ECC” group).
