A substance found in green tea could help to redress a cognitive imbalance associated with Down’s syndrome, according to a study conducted at the Institute of bio-membrane and bio-energy at the National Research Council (IBBE-CNR), in Bari, Italy. Epigallocatechin-3-gallate(EGCG) is a natural antioxidant from the polyphenol family and is present in green tea. This substance could be important in helping to reduce some of the symptoms of Down’s syndrome, which is caused by the presence of an extra chromosome. People with Down’s syndrome suffer from mental retardation and early ageing with premature neural deterioration. EGCG has a positive effect on mitochondrial dysfunction, which is one of the principal causes of the early neurodegeneration.
