High BDNF Tied to Lower Alzheimer’s Risk

Growth hormone for the brain. What a concept. Truth is, science has indeed identified a protein that does exactly that, and it’s called brain-derived neurotrophic hormone (BDNF). Knowing about BDNF is even more important now, as a new report clearly links higher levels of BDNF to remarkably reduced risk for Alzheimer’s disease.

In a recent issue of the Journal of the American Medical Association, researchers from Boston University measured baseline BDNF levels in a group of adults and followed them for up to ten years. They found that those individuals with the highest baseline BDNF levels developed dementia 50% less often compared to those with the lowest levels.

BDNF is a protein that plays a pivotal role in neuronal health. Your brain contains as many as 100 billion neurons and the health, vitality, and, perhaps most importantly, functionality of each one of your brain cells is intimately influenced by BDNF.

Early in life, BDNF regulates not only the growth of brain cells, but also their ability to make connections to other brain cells, a process fundamental to our ability to create a more powerful brain. But keep in mind that the process of growing new brain cells, neurogenesis, continues throughout your entire life! Think of it. As you are reading this report, your brain is actively producing new brain cells, and brain cells are always busy creating new connections with their neighbors in a process called neuroplasticity.

Both of these events, neurogenesis and neuroplasticity, are directly enhanced by BDNF, and who wouldn’t more brain cells that are more connected? No doubt you are now wondering what you can do to get hold of this magic elixir that builds a better brain. But while BDNF isn’t something you can buy at the pharmacy, the good news is that you can absolutely increase your body’s ability to create this powerful protein and pave the way for a healthier, more resilient brain.

I’ve discussed how the omega-3 oil DHA can enhance BDNF as well as how it can be enhanced with aerobic exercise in previous posts. You can get a lot more information beginning on page 126 in Grain Brain.

I’ve also written about how sunlight can turn on BDNF production. In this report from Dr. Marc Molendijk and colleagues at Leiden University in the Netherlands, a profound seasonal variation in blood level of BDNF was observed with increasing amounts of BDNF found in the blood during months with the most sunshine. Interestingly, they were able to correlate levels of BDNF with the diagnosis of depression as well with low BDNF levels highly related to this diagnosis. This information has important implications. Not only does it offer up yet another lifestyle modification to provide our bodies with more BDNF (sunlight exposure), it might well explain why individuals may become depressed during winter months and when living in places with little sunshine.

Despite the literally hundreds of millions of research going in to finding a way to treat Alzheimer’s, it looks like that prospect remains a long way off. So we should pay attention to research that shows how the disease could be prevented in the first place. Getting sunshine, exercise and taking DHA are proven methods to raise BDNF, and now we see the science that clearly correlates elevated levels of this powerfully important factor with reduced Alzheimer’s risk.

    I’m pretty sure the mushroom lions mane enhances bdnf.

    • Chooilin Lim

      Pls suggest how to use. I see the mushrooms in TCM shops. Thank you.

  • sher

    Thing is with the extreme long winter, and now cloudy spring, it is almost impossible to get sun

  • Anna

    Why can’t we help those with Alzheimers i.e. the same as we are taking care of
    ourselves – would that delay the ongoing dementia?

  • Barbara Hickman

    Coconut oil increases BDNF production. Read Bruce Fife’s (C.N, N. D) The Coconut Oil Miracle, Stop Alzheimer’s Now!, and Stop Autism Now!

  • Barbara Hickman

    Coconut oil is converted by the liver into ketones that feeds and heals the brain damage, reduces inflammation, and provides 39% more oxygen to the brain. Everyone needs to read Dr. Bruce Fife’s book The Coconut Oil Miracle. John Hopkins in MD is working with ketogenic diets for brain degenerative diseases.

    How much coconut oil does this Dr. suggest taking per day?

  • CallMeAnn

    But, will it reverse the condition? I tried giving my mother CO for this purpose, but without result. I find I can not give her the quantity I have read to be effective, due to her bowel loosening.

  • Barbara Hickman

    Initially 1-4 Tablespoons/day. Adapt up to 2 tablespoons 3-4 times a day.

  • Sally Smith

    Is saccarin a good substitute for sugar in coffee and tea?

    • David Perlmutter

      I advise Stevia.

  • Tamra Brown

    Wonder if LUX lights can help during the winter to boost BDNF?

  • Steve Ellis

    Is there a good, recommended Soft Gel for BDNF?
