Summary : Omega-3 long chain polyunsaturated fatty acids (n-3 LCPUFA) are important constituents of the maturing brain and therefore considered crucial for brain development
in utero and in early infancy. However, it is uncertain whether n-3 LCPUFA supplementation during pregnancy and lactation can have beneficial, sustainable effects on visual or cognitive development. Beneficial effects on child cognitive function after supplementation with EPA and DHA during pregnancy and lactation were observed at 4 years of age, but not at 3, 6 months or 7 years. In term infants LCPUFA when given in relative high dosages, seems to improve visual acuity, but not cognitive function. Evidence for an effect of LCPUFA supplementation of preterm infants remains inconclusive. In children older than 2 years of age, epidemiological evidence suggests an association between psychiatric or neurodevelopmental disorders and omega-3 fatty acid deficiencies. However, the evidence from randomized controlled trials exploring the impact of omega-3 fatty acids on cognitive performance or brain function in school-aged children is not conclusive. In conclusion, n-3 LCPUFA are highly present in the maturing brain and are important for normal brain functioning and development. When provided in relative high dosages, n-3 LCPUFA may improve visual acuity in term infants. However, it remains unclear whether supplementation with n-3 LCPUFA during pregnancy, early infancy, and childhood can improve cognitive function. |
