Cognitive domains were assessed using the Griffith Mental Developmental Scales III on 136 PSAC. Multivariate logistic regression was used to determine the level of association between <jats:italic>S<\/jats:italic>. <jats:italic>haematobium<\/jats:italic> infection and performance in the cognitive domains adjusting for confounding factors (i.e. nutrition, hemoglobin levels, gender and age).

Improvement of cognitive performance was observed at 6 months post treatment in the following Domains; Language and Communication Domain (p\u2009=\u20090.003), Eye-Hand Coordination Domain (p\u2009=\u20090.02) and General Development Domain (p\u2009=\u20090.006).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The study showed that <jats:italic>S. haematobium<\/jats:italic> infection in PSAC is associated with lower cognitive scores in the Foundation of Learning, Language and Communication, Eye-Hand Coordination, Personal-Social-Emotional and in the Overall General Development domains.
