Abstract
ABSTRACT Children in Uganda are at risk for significant cognitive sequelae from severe malaria. Computerized cognitive rehabilitation training (CCRT) represents a potential method to improve working memory, behavior, and executive functioning, cognitive domains most at risk following severe malaria. The primary aim of this study was to complete a secondary analysis of data from a concluded CCRT randomized control trial in order to compare the training efficiency of a commonly used CCRT program under conditions of titrated (adaptive) or non-titrated (non-adaptive) training and with children with increasing malaria severity to determine how various factors may affect potential CCRT improvement. A total of 201 school-aged children (66.2% boys) who were either healthy (n = 102) or previously diagnosed with severe or cerebral malaria (n = 99) were randomized into two active treatment arms (titrated and non-titrated learning). Each child received 24 one-hour sessions of training over 8 weeks using Captain’s Log® CCRT by BrainTrain, which includes a comprehensive set of CCRT tasks. Children generally benefited from CCRT over the 24 training sessions, but titrated CCRT showed a clear advantage over non-titrated. Severity of illness or factors such as BMI, did not moderate CCRT performance indicators. These findings support our hypothesis that titrated CCRT would result in steeper improvement in learning, but do not support our hypothesis that history of recent significant illness would affect learning proficiency. Findings were evident across all CCRT performance scores, even given that children were from generally rural, low-resource settings and were generally unfamiliar with computers.
