Green tea and blueberries can protect you from DEMENTIA, study shows

  • Compounds in tea and berries reduced plaques strongly associated with Alzheimer’s disease
  • Alzheimer’s is the most common cause of the degenerative disease of dementia
  • The findings apply to more than 6 million Americans suffering from Alzheimer’s disease

Green tea can prevent dementiathe study shows.

Chemicals found in a herbal drink called catechins reduced the plaques strongly associated with Alzheimer’s disease in a laboratory study.

The compound resveratrol – found in blueberries, grapes and red wine – also had a similar effect on human brain cells.

Catechins and resveratrol have anti-inflammatory properties, which may explain their ability to clear plaque.

Tufts University researchers published their findings in a journal Biology and medicine of free radicals.

Alzheimer’s is the most common form of dementia affecting more than six million Americans.

It is characterized by a lack of communication between neurons in the brain, leading to loss of function and cell death.

Catechins are compounds in green tea that have antioxidant-like effects that help prevent cell damage and calm inflammation in the brain. Tufts researchers looked at this and 20 other compounds for their anti-Alzheimer’s properties, including resveratrol, common in blueberries and grapes.

What is Alzheimer’s disease?

Alzheimer’s disease is a progressive, degenerative brain disease in which the accumulation of abnormal proteins causes nerve cells to die.

This disrupts the transmitters that transmit messages and causes the brain to shrink.

More than 5 million people suffer from the disease in the US, where it is the sixth leading cause of death, and more than a million Britons have it.

WHAT IS HAPPENING?

As brain cells die, the functions they provide are lost.

This includes memory, orientation and the ability to think and reason.

The progress of the disease is slow and gradual.

On average, patients live five to seven years after diagnosis, but some may live ten to 15 years.

EARLY SYMPTOMS:

  • Loss of short-term memory
  • Disorientation
  • Changes in behavior
  • Mood swings
  • Difficulties with money or phone calls

LATER SYMPTOMS:

  • Severe memory loss, forgetting close family members, familiar objects or places
  • Becoming anxious and frustrated at the inability to understand the world, leading to aggressive behavior
  • Eventually he loses the ability to walk
  • He may have problems eating
  • Most will eventually need 24-hour care

In the Alzheimer’s brain, abnormal levels of certain naturally occurring proteins clump together to form plaques that collect between neurons and interfere with cell function.

But catechins and resveratrol have been shown to be effective in reducing plaque formation in these neural cells. And they did it with little to no side effects.

Some other compounds tested, including curcumin from turmeric, the diabetes drug metformin and a compound called citicoline, also prevented plaque formation.

They tested the efficacy of 21 compounds in a 3D model of neural tissue made from a non-reactive silk sponge seeded with human skin cells that had been genetically reprogrammed into self-renewing neural stem cells.

dr. Dana Cairns, a research associate at Tufts School of Engineering and leader of the study, said: ‘We were lucky that some of them showed quite strong efficacy.

‘In the case of these compounds that passed the test, they had almost no visible deposits after about a week.’

The research team’s findings, which point to the anti-plaque properties of common compounds, have the potential to help millions and build on years of research into their therapeutic benefits.

Green tea and berries are rich in flavonoids that can reduce cell-damaging free radicals and calm inflammation in the brain and improve blood flow to the brain.

The Tufts researchers’ findings do not conclusively suggest that the neuroprotective properties of the 21 studied compounds will help halt the progression of dementia.

Some of the compounds studied, for example, are not easily absorbed into the body or bloodstream.

And some compounds could not penetrate the blood-brain barrier, the barrier between the brain’s blood vessels and the cells and other components that make up brain tissue.

The purpose of the blood-brain barrier is to protect against circulating toxins or pathogens that could cause brain infections.

Further research is needed on the adaptability of these compounds to better penetrate the bloodstream and the blood-brain barrier, according to Dr. Cairns.

But her team’s findings are significant because there is currently no cure for Alzheimer’s disease, and treatments to slow the disease’s progression are limited.

Alzheimer’s disease is not the only cause of dementia, which affects more than 7 million people in the US. Other causes include Parkinson’s disease and vascular dementia caused by conditions that block or reduce blood flow to different regions of the brain.
