Non-organic failure to thrive.

Non-organic failure to thrive is a clinical diagnosis which should be considered in parallel with other causes of failure to thrive in infants. It has not been resolved as to whether the condition is due to a lack of stimulation or to deprivation of calories, although both these factors, as well as a contribution from the child in some cases, are likely to be responsible. There is no typical profile of the parent whose child develops non-organic failure to thrive. The condition can occur in all social classes but is more common in situations of poverty, poor marital relationships, chaotic family lifestyle and when there is a history of deprivation in the parents' own childhood. Although the majority of these children eventually show catch-up growth, long-term follow-up studies show a high incidence of emotional and cognitive problems. Treatment should go beyond nutritional rehabilitation in the hospital and should include practical, supportive help for the mother together with measures to improve the level of stimulation and the quality of interpersonal relationships for the child.
