A research done in Centre for Genomic Regulation (CRG) in Barcelona,
Spain reveals how the compound in green tea called epigallocatechin gallate
(EGCG) improved the cognitive function of individuals with Down syndrome.
Down syndrome is the
most common genetic condition,occurring when an individual has a partial or
full additional copy of chromosome 21, meaning they have three copies of this
chromosome, rather than the normal two.
This extra chromosome leads to over expression of genes, which can
cause a number of physical symptoms, including reduced muscle tone, a small
head, ears, and mouth, a flattened facial profile, and upward-slanting eyes.
Individuals with Down syndrome may also experience problems with
cognitive function, such as delayed language and speech development, learning
and memory impairments, and poor concentration.
According to the researcher,Dr. Dierssen, research has shown that
such cognitive impairments are down to overexpression of a gene called DYRK1A,
and studies in mice have suggested the compound EGCG could reduce DYRK1A
overexpression.
Now, the new study indicates that the compound could do the same
for people with Down syndrome, achieving an improvement in cognitive function.
