Cerebral Vasoreactivity in Children with Sickle Cell Disease: A Transcranial Doppler Study


Impairment of vasodilatory capacity reflecting reduced cerebrovascular reserve was previously shown in adults with sickle cell disease (SCD) and might play a role in the pathophysiology of stroke in such patients. We examined the hypothesis that children with SCD would also have a higher frequency of impaired cerebral vasoreactivity when compared with healthy age- and gender-matched controls.
