Determine the effect of moderate to heavy Trichuris trichiura (whipworm) infection on cognitive functions in children and evaluate if anthelmintic therapy reverses these deficits.
Conducted a double-blind, placebo-controlled trial among 159 schoolchildren aged 9–12 years in Jamaica.
Randomly assigned infected children to receive either treatment or placebo, comparing them against an uninfected control group over a 9-week follow-up.
Evaluated cognitive improvements using stepwise multiple linear regression to adjust for potential confounding variables.
Worm expulsion significantly improved auditory short-term memory test performance (P < 0.02 and P < 0.01) and long-term memory scanning and retrieval (P < 0.001).
By week 9, cognitive performance in treated children was no longer significantly different from uninfected controls, with T. trichiura expulsion demonstrating a greater effect on improvement than Ascaris lumbricoides removal.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Randomized double-blind trial demonstrates that treating Trichuris trichiura infection reverses memory deficits in schoolchildren, indicating that whipworm-induced cognitive impairment is treatable.
