In the observation of the effects of Green tea consumption and psychological distress of the study of "Green tea consumption is associated with lower psychological distress in a general population: the Ohsaki Cohort 2006 Study" by Atsushi Hozawa, Shinichi Kuriyama, Naoki Nakaya, Kaori Ohmori-Matsuda, Masako Kakizaki, Toshimasa Sone, Masato Nagai, Yumi Sugawara, Akemi Nitta, Yasutake Tomata, Kaijun Niu, and Ichiro Tsuji[21a], researchers found that The odds ratio (with 95% CI) of developing psychological distress among respondents who consumed ≥5 cups of green tea/d was 0.80 (0.70, 0.91) compared with those who consumed <1 cup/d and concluded that Green tea consumption was inversely associated with psychological distress even after adjustment for possible confounding factors.

b. In the investigation of Green tea consumption and the risk of depressive symptoms of the study of "Green tea consumption is associated with depressive symptoms in the elderly" by Niu K, Hozawa A, Kuriyama S, Ebihara S, Guo H, Nakaya N, Ohmori-Matsuda K, Takahashi H, Masamune Y, Asada M, Sasaki S, Arai H, Awata S, Nagatomi R, Tsuji I.[20b], researchers found that the prevalence of mild and severe and severe depressive symptoms was 34.1% and 20.2%, respectively and concluded that a more frequent consumption of green tea was associated with a lower prevalence of depressive symptoms in the community-dwelling older population.

c. In the evaluation of the effects of (-)-Epigallocatechin gallate (green tea polyphenol) and acute stress responses of the study of "(-)-Epigallocatechin gallate attenuates acute stress responses through GABAergic system in the brain" by Adachi N, Tomonaga S, Tachibana T, Denbow DM, Furuse M., researchers found that EGCG on distress-induced vocalization were significantly attenuated by the GABAA receptor antagonist picrotoxin but not by the GABAB receptor antagonist CGP 54626 (3-N-(1-(3,4-dichlorophenyl)ethylamino)-2-hydroxypropyl cyclohexylmethyl phosphinic acid hydrochloride) and concluded that EGCG has sedative and hypnotic effects in the brain, partially through GABAA receptors, and consequently moderates an acute stress response.

Health Benefits
11. Congitive Activities
a. In the evaluation of the effect of tea polyphenol (TP) on cognitive and anti-cholinesterase activity of the study of "Effects of green tea polyphenol on cognitive and acetylcholinesterase activities" by Kim HK, Kim M, Kim S, Kim M, Chung JH.[11a], researchers found that TP exhibited a dramatic inhibitory effect on acetylcholinesterase activity. This finding suggests that TP might be useful in the treatment of Alzheimer's disease.

b. In rhe investigation of green tea catechin, induces HO-1 by ARE/Nrf2 pathway in hippocampal neurons in protection of neurons against different models of oxidative damages of the study of "Modulation of Nrf2/ARE pathway by food polyphenols: a nutritional neuroprotective strategy for cognitive and neurodegenerative disorders" by Scapagnini G, Vasto S, Abraham NG, Caruso C, Zella D, Fabio G.[11b], researchers found that caffeic acid phenethyl ester and ethyl ferulate, are also able to protect neurons via HO-1 induction. These studies identify a novel class of compounds that could be used for therapeutic purposes as preventive agents against cognitive decline.

c. In the assessment of the combination of green tea extract and l-theanine (LGNC-07) in congitive effects of the study of "A combination of green tea extract and l-theanine improves memory and attention in subjects with mild cognitive impairment: a double-blind placebo-controlled study" by Park SK, Jung IC, Lee WK, Lee YS, Park HK, Go HJ, Kim K, Lim NK, Hong JT, Ly SY, Rho SS.[11c], researchers wrote that brain theta waves, an indicator of cognitive alertness, were increased significantly in the temporal, frontal, parietal, and occipital areas after 3 hours in the eye-open and reading states. Therefore, this study suggests that LGNC-07 has potential as an intervention for cognitive improvement.

d. In the evaluation of l-Theanine and its effects of Amyloid beta (Abeta)-induced neurotoxicity which is a major pathological mechanism of Alzheimer disease (AD) of the study of "l-Theanine, an amino acid in green tea, attenuates beta-amyloid-induced cognitive dysfunction and neurotoxicity: reduction in oxidative damage and inactivation of ERK/p38 kinase and NF-kappaB pathways" by Kim TI, Lee YK, Park SG, Choi IS, Ban JO, Park HK, Nam SY, Yun YW, Han SB, Oh KW, Hong JT.[11d], researchers suggested that the positive effects of l-theanine on memory may be mediated by suppression of ERK/p38 and NF-kappaB as well as the reduction of macromolecular oxidative damage.
