Seven patients with hemolytic-uremic syndrome who had major neurologic
al symptoms during the acute illness were neurologically and cognitive
ly evaluated prospectively several years after recovery from the illne
ss. Four patients showed evidence of subtle neurological sequelae, inc
luding posturing, clumsiness, poor fine-motor coordination, hyperactiv
ity, and distractibility. Psychoeducational evaluation of all seven su
bjects revealed mean scores within the average range in cognitive abil
ities, academic achievement, single word receptive vocabulary, visual/
motor planning, overall adaptive functioning, and hyperactivity. The l
apse of time (minimum of 7 years) between the acute illness and the ps
ychometric evaluation could have been responsible for our normal resul
ts.
