Benefits of Green Tea for Alzheimer’s

A common beverage may be able to protect you from Alzheimer’s disease and boost brain health. Several studies show that green tea has the potential to protect brain cells, improve memory and delay Alzheimer’s. The affordable and accessible drink has shown promise in research in recent years.

Benefits of Green Tea for Alzheimer's

Green Tea Protects Brain Cells

Studies show that green tea could prevent Alzheimer’s by protecting the brain from the formation of beta-amyloid plaques that are thought to cause the disease. A flavonoid in green tea called EGCG (epigallocatechin-3-gallate) can bind to beta-amyloid proteins to prevent formations, and ultimately, prevent Alzheimer’s disease.

While research has shown the effects of green tea on beta-amyloids, one of the most notable studies used MRI technology to actually view its effect. Participants in the study were given either a green tea or a placebo beverage, and their brain activity was then monitored using an MRI machine. Those who received the green tea drink had a notable increase in brain activity, and researchers also found a “dose-response” in the participants, meaning brain activity increased as more green tea was consumed.

Green Tea Can Improve Your Memory

A new study published in Psychopharmacology in March 2014 found that green tea can actually help improve cognitive function and may be useful in treating patients who have Alzheimer’s or dementia. In the study, half of the participants were given a drink that  had green tea extract and the other half were given the same drink with no extract.

Again, using MRI technology, researchers observed that the participants who drank the green tea extract showed increased brain activity in the areas of the brain that are responsible for memory function.

Due to the success of these studies, researchers plan to do more to test the potential of green tea in treating cognitive impairments like dementia and Alzheimer’s.

The Future of Green Tea As An Alzheimer’s Treatment

While studies of the effects of green tea on brain health look promising, there is a lot of work to be done before it can actually be used as a treatment method for Alzheimer’s patients.

For starters, the disease’s main fighting ingredient found in green tea, ECGC, isn’t available for patenting by pharmaceutical companies which will limit investment for clinical trials. Also, more research needs to be done to determine the direct link between brain health and ECGC to rule out any other ingredients that may have had an effect on cognition, such as caffeine.

    A lot of public money is going into Alzheimer research. Is it right that potential cures should be limited to what can and cannot be patented?

  • Glad it can’t be patented because most of the time they find taking just one part of something that is beneficial never has the same impact as using the real thing. Just keep drinking the tea, exercising, drinking water, and eating healthy omega 3 fats!

    I agree, just because a pharmaceutical company cannot patent the ingredient to make tons of money, doesn’t mean the research shouldn’t be done !! Very sad indeed.

    I recently experienced a significant improvement in memory, energy, and ability to sort things out. Since I’m close to 70 years old, it was like a new lease on life. Curious, I began to analyze what was new in my life’s habits or diet, when I realized that the one new thing was a daily cup of green tea. The effect is quite amazing. I intend to increase consumption to 2 or 3 cups a day.

    The “duh” response is give them green tea! And this is why despite the fact my beloved father has Alzheimers I refuse to give to the Alzheimers Association. I do my research online and make sure he gets the things I find. He is IMPROVING. Why they won’t simply suggest these patients drink green tea is unforgiveable.!

      Kathy, I also am using a well-rounded and non-prescription protocol for my mother. I would like to confer with you. Perhaps we can help each other. Look for me on FB, please.

        I give my grandma virgin coconut oil turmeric coco nectar and ginger and they all help in making her feel calm. She is able to sleep longer and she doesn’t have as many tantrums. Her memory has also improved a lot.

    I’m ‘young’ at 56 years old. My mother has advanced dementia. Because of it, I confess I obsess a little when I forget things that may be normal at my age. I’m an avid reader, and often don’t remember names of characters. Currently I’m reading a novel with a LOT of characters and realized I remember the names of all of them. Why? What has changed? Well, I typically drink black or early grey in the morning. I bought my husband a huge box of green tea from Costco since he started drinking it and decided to drink it when I had run out of my earl grey. So when I noticed the memory improvement, I googled ‘green tea and memory’ since that was the only change I could think of and was surprised at what I found. I guess I’ll keep drinking the green tea whether it’s the reason for memory improvement or not….

    I’ve been a medical coder since 2004 and stopped drinking coffee in 2014 for it’s anti inflammatory effects. When the US switched from ICD-9 to ICD-10 codes I found my ability to recall the old codes was surprisingly acute. I never gave much thought to the relationship of memory to green tea but it now makes sense. I’ve since retired but my memory is still sharp.
