A study led by Stefan Borgwardt, MD, PhD, from the Department of Psychiatry, University of Basel, Switzerland, shows that green tea extract enhances memory and is good for brain function, a finding that researchers suggest may have important clinical implications for the treatment of neuropsychiatric disorders.

This is “the first evidence for the putative beneficial effect of green tea on cognitive functioning, in particular, on working memory processing at the neural system level by suggesting changes in short-term plasticity of parieto-frontal brain connections,” the investigators write.

The study was published online March 19 in Psychopharmacology.

Boosts Brain Plasticity

Several studies have suggested that green tea enhances brain function but until now the mechanisms have been poorly understood.

The investigators recruited 12 healthy male volunteers who consumed either 27.5 grams of green tea extract or a similar drink without green tea.

Participants were given  memory tasks while undergoing functional magnetic resonance imaging (fMRI).

fMRI results showed increased connectivity between the parietal and the frontal cortex of the brain with the green tea extract, and these neuronal findings correlated positively with improvement in task performance.

“Our findings suggest that green tea might increase the short-term synaptic plasticity of the brain,” Dr. Borgwardt said in a statement.

“Modeling effective connectivity among frontal and parietal brain regions during working memory processing might help to assess the efficacy of green tea for the treatment of cognitive impairments in neuropsychiatric disorders such as dementia,” the researchers conclude.

So is green tea good for brain function, for dementia, stress, poor memory, even just an aging brain? We say absolutely!!

We recommend Brahmitone which contains green tea as well as Gingko, Withania, Tyrosine and Bacopa. Together these herbs increase brainneurotransmitters and support general cognitive functions.
