According to 2020 research, green tea is associated with lower levels of certain markers of Alzheimer’s disease. This may be due to the presence of some bioactive compounds such as EGCG and L-theanine. (Source 13)

But, a recent study has found that drinking too much, thirteen cups or more a day (all types of tea), could increase the risk of Alzheimer’s disease. (Source 14)

Clinical evidence about how exactly green tea influences the human brain is lacking. (Source 15)

More high-quality research on humans is needed.
