Tea and Neurological Decline

In an animal model study, researchers found that the tea catechin EGCG was
capable of reducing biomarkers associated with Alzheimer's disease. Using
strains of mice transgenically bred to be prone to develop Alzheimer's disease,
the researchers found that exposure to EGCG resulted in reduced production of
amyloid protein, a marker for the development of plaques associated with
Alzheimer's disease.
