Objective: Our earlier studies on Ugandan children surviving cerebral malaria showed cognitive deficits mainly in attention and memory. We now present the first study in sub-Saharan Africa to investigate the feasibility and potential benefits of computerized cognitive rehabilitation training on neuropsychological and behavioral functioning of children surviving cerebral malaria.
Methods: A randomized trial in which 65 children admitted 45 months earlier with cerebral malaria were recruited at Mulago Hospital, Kampala, Uganda. For 8 weeks, 32 of the children received weekly training sessions using Captain's Log cognitive training software and the other 33 were assigned to a nontreatment condition. Pre- and postintervention assessments were completed using CogState, a computerized neuropsychological battery, measuring visuomotor processing speed, working memory, learning, attention and psychomotor speed and the Child Behavior Checklist measuring internalizing problems, externalizing problems, and total problems.
Results: Preintervention scores were similar between both groups. Treatment effects were observed on visuospatial processing speed [group effect (standard error) 0.14 (0.03); p < .001], on a working memory and learning task [0.08 (0.02); p < .001], psychomotor speed [0.14 (0.07); p = .04], and on internalizing problems [-3.80 (1.56); p = .02] after controlling for age, sex, school grade, quality of the home environment, and weight for age z scores. Similar treatment effects were observed when no adjustments for the above covariates were made.
Conclusions: Computerized cognitive training long after the cerebral malaria episode has immediate benefit on some neuropsychological and behavioral functions in African children. The long-term benefit of this intervention needs to be investigated.
