Mental and behavioral effects of parasitic infections: a review.
Whether parasitic diseases-and in particular helminth infections because they are extensive and widespread--have an effect on mental functions and educational attainment is by no mean a new question. Concern about the possibility was evident in the early decades of the century, and the results of investigations designed to discover whether the effects of parasite infections had consequences on school children. Many species of helminth have been reported as causing infections in humans. Of the nematode infections, both soil transmitted helminthiasis and lymphatic filariasis are public health problem in the country. Any of these infections may result in morbidity, malnutrition, and iron-deficiency anaemia. Their possible contribution to impaired cognitive function and educational achievement is by the association between iron deficiency anaemia and malnutrition. Research on the effects of parasitic infection has focused on school-age children. Not only are these children the most vulnerable to parasitic infections--they are also the population group most likely to experience the impact of infection on cognitive function. This review paper discusses the mental and behavioral effects of parasitic infection on child's health. Infected children are less active; their behavior is said to be sluggish and both mental and physical activities and processes appear dulled and slow. A reduction in available energy is likely to cause a cascade of effects running through most aspects of the host's daily mental life and behavior.
