Green Tea Found to Enhance Cognitive Ability:
Improves Memory, May Help Dementia
Subjects do much better on test after taking green
tea extract; can it treat dementia?
April 7, 2014 Green tea extract enhances the
cognitive functions and in particular the working memory, say
researchers from the University of Basel,
Switzerland, who claim to be the first to prove this benefit in green
tea. They see distant possibilities, too, for treating dementia.
The Swiss findings suggest promising clinical
implications for the treatment of cognitive impairments in psychiatric
disorders such as dementia. The academic journal Psychopharmacology
has published their results.
Green tea is often credited with many positive
effects on health. In the past the main ingredients of green tea have
been thoroughly studied in cancer research.
Recently, scientists have also been inquiring into
the beverage's positive impact on the human brain. Different studies
were able to link green tea to beneficial effects on the cognitive
performance. However, the neural mechanisms underlying this cognitive
enhancing effect of green tea remained unproven.
In a new study, the researcher teams of Prof.
Christoph Beglinger, University Hospital of Basel, and Prof. Stefan
Borgwardt, Psychiatric University Clinics, found that green tea extract
increases the brain's effective connectivity, meaning the causal
influence that one brain area exerts over another. This effect on
connectivity also led to improvement in actual cognitive performance:
Subjects tested significantly better for working memory tasks after the
admission of green tea extract.
For the study healthy male volunteers received a
soft drink containing several grams of green tea extract before they
solved working memory tasks. The scientists then analyzed how this
affected the brain activity of the men using magnetic resonance imaging
The MRI showed increased connectivity between the
parietal and the frontal cortex of the brain. These neuronal findings
correlated positively with improvement in task performance of the
Our findings suggest that green tea might increase
the short-term synaptic plasticity of the brain, says Borgwardt.
The research results suggest promising clinical
implications. Modeling effective connectivity among frontal and parietal
brain regions during working memory processing might help to assess the
effectiveness of green tea for the treatment of cognitive impairments in
neuropsychiatric disorders such as dementia.
Financial Relief for Volkswagen Diesel Owners
You may be eligible for money damages if you owned or leased one of these VW, Porsche or Audi vehicles.
In the major scandal of 2015, Volkswagen cheated you and the world. They rigged diesel emission controls so you, nor regulators, would know how much pollution their cars were adding to our environment.
They were caught and have reserved $7.3 billion to help "make it right" with victims.
