  • Compounds in tea and fruit cut back platelets that have been linked to Alzheimer’s illness
  • Alzheimer’s is the commonest reason for dementia
  • The findings apply to greater than 6 million Americans residing with Alzheimer’s illness

Research shows that green tea prevents dementia.

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

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

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

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

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

It is characterised by an absence of communication between neurons within the mind, leading to lack of operate and cell loss of life.

Catechins are compounds in green tea that have antioxidant-like results that assist forestall cell injury and cut 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 often 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 reason for loss of life, and greater than 1 million Britons are affected.


Brain cells die, the features they supply are misplaced.

This contains reminiscence, orientation, and the power to suppose and motive.

The development of the illness is sluggish and gradual.

On common, sufferers reside 5 to 7 years after prognosis, with some residing so long as ten to fifteen years.


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


  • Severe reminiscence loss, forgetting shut relations, acquainted issues or locations
  • Anxiety and frustration as a result of incapacity to know the world, resulting in aggressive habits
  • Eventually he loses the power to stroll
  • Eating issues might happen
  • Most will ultimately 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 operate.

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

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

They examined the efficacy of 21 compounds in a 3D neural tissue mannequin fabricated 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 had been lucky that a few of them confirmed very robust efficacy.

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

The analysis staff’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 cut back cell-damaging free radicals, cut back irritation within the mind, and enhance blood circulation to the mind.

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

For instance, among the compounds studied aren’t 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 function 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 circulation and permeability of the blood-brain barrier.

But his staff’s findings are necessary as a result of there may be at the moment no treatment for Alzheimer’s illness, and therapies to sluggish the development of the illness are restricted.

Alzheimer’s illness just isn’t the one reason for dementia, which impacts greater than 7 million individuals within the United States. Other causes embody Parkinson’s illness and vascular dementia, which is brought on by circumstances that block or cut back blood circulation to totally different areas of the mind.
