  • Compounds in tea and fruit scale back platelets that have been linked to Alzheimer’s illness
  • Alzheimer’s is the most typical explanation for dementia
  • The findings apply to greater than 6 million Americans dwelling with Alzheimer’s illness

Research shows that green tea prevents dementia.

Chemicals present in an natural drink known as catechins have been proven to scale back platelets in a laboratory study, which have been linked to Alzheimer’s illness.

The complement resveratrol – present in blueberries, grapes and crimson wine – had an analogous impact on human mind cells.

Catechins and resveratrol have anti-inflammatory properties, which explains their capacity to clear plaque.

Tufts University researchers revealed their findings within the journal Free Radical Biology and Medicine.

Alzheimer’s illness is the most typical type of dementia, affecting greater than six million Americans.

It is characterised by a scarcity of communication between neurons within the mind, leading to lack of perform and cell demise.

Catechins are compounds in green tea that have antioxidant-like results that assist forestall cell injury and scale back irritation within the mind. Tufts researchers checked out these and 20 different compounds for his or her anti-Alzheimer’s properties, together with resveratrol, which is usually present in blueberries and grapes.

What is Alzheimer’s?

Alzheimer’s illness is a progressive, degenerative mind illness by which the buildup of irregular proteins causes nerve cells to die.

This disrupts the channels that carry messages and causes the mind to shrink.

More than 5 million individuals within the US are affected by the illness, which is a number one explanation for demise, and greater than 1 million Britons are affected.


Brain cells die, the capabilities they supply are misplaced.

This contains reminiscence, orientation, and the flexibility to assume and cause.

The development of the illness is sluggish and gradual.

On common, sufferers stay 5 to 7 years after analysis, with some dwelling so long as ten to fifteen years.


  • Short-term reminiscence loss
  • disorientation
  • Behavioral modifications
  • temper modifications
  • Problems with cash or telephone calls


  • Severe reminiscence loss, forgetting shut members of the family, acquainted issues or locations
  • Anxiety and frustration resulting from incapacity to grasp the world, resulting in aggressive conduct
  • Eventually he loses the flexibility to stroll
  • Eating issues might happen
  • Most will finally want 24-hour care

In the mind with Alzheimer’s illness, irregular ranges of sure naturally occurring proteins clump collectively and accumulate between neurons, disrupting cell perform.

However, catechins and resveratrol have confirmed efficient in decreasing plaque formation in these neuron cells. And they did it with little or no unwanted side effects.

Some different compounds examined, together with curcumin in turmeric, the antidiabetic drug Metformin, and a compound known as citicoline additionally prevented plaque formation.

They examined the efficacy of 21 compounds in a 3D neural tissue mannequin made from non-reactive silk sponge seeded with human pores and skin cells that had been reworked into self-renewing neuron cells by genetic reprogramming.

Dr. Dana Cairns, a researcher on the Tufts School of Engineering and chief of the study, mentioned: “We have been lucky that a few of them confirmed very sturdy efficacy.

“In these compounds that have been screened, they did not present any spots after a few week.”

The analysis workforce’s findings demonstrating the anti-plaque properties of generally discovered compounds profit thousands and thousands of individuals and have a few years of analysis into their therapeutic advantages.

Green tea and berries are wealthy in flavonoids, which scale back cell-damaging free radicals, scale back irritation within the mind, and enhance blood move to the mind.

The Tufts researchers’ findings don’t definitively recommend that the neuroprotective properties of the 21 compounds studied might assist halt the development of dementia.

For instance, among the compounds studied will not be simply absorbed by the physique or blood.

And some compounds didn’t cross the blood-brain barrier, the barrier between the mind’s blood vessels and the cells and different parts that make up mind tissue.

The goal of the blood-brain barrier is to protect the mind from toxins or pathogens that trigger an infection.

According to Dr. Cairns, there’s a have to study the difference of those compounds to enhance blood move and permeability of the blood-brain barrier.

But his workforce’s findings are essential as a result of there may be at the moment no remedy for Alzheimer’s illness, and remedies to sluggish the development of the illness are restricted.

Alzheimer’s illness isn’t the one explanation for dementia, which impacts greater than 7 million individuals within the United States. Other causes embrace Parkinson’s illness and vascular dementia, which is attributable to situations that block or scale back blood move to completely different areas of the mind.
