A chemical in green tea has been shown to improve memory, speaking and behaviour in people with Down's syndrome, doctors claim.
In a year-long clinical trial, the treatment led to improved scores on tests and improved quality of life, a study published in The Lancet Neurology found. The positive impact remained six months after the trial ended.
Brain scans revealed that the compound, called epigallocatechin gallate, altered the way brain cells connect with one another.
'This is the first time that a treatment has shown to be effective in the cognitive improvement of persons with this syndrome,' said Professor Mara Dierssen, senior author of the study and a researcher at the Centre for Genomic Regulation in Barcelona.
While significant, she added in a statement, the results should not be interpreted as a 'cure'.
'But it may be a tool to improve these individuals' quality of life.'
Commenting on the study, experts described it as 'exciting' and 'an important piece of work.' At the same time, they cautioned the findings must be validated in additional trials.
