Research shows Lion’s mane mushroom can combat dementia and cognitive decline


Currently, there are more than 55 million people who suffer from dementia worldwide, and nearly 10 million new cases of dementia are diagnosed each year. Cognitive decline has become such a pervasive issue in modern society; it has become normalized across the political spectrum. Some of today’s government officials show serious cognitive decline, and even the de facto President of the United States routinely stumbles around in a stupor, taking cues from handlers and mumbling incoherently at times.

Cognitive decline is a serious health issue worldwide, but in many cases, there are ways to reverse the damage, prevent the death of neurons and regenerate neuronal pathways. Lion’s mane mushroom is an important medicinal food that can promote the biosynthesis of nerve growth factor and effectively combat dementia.

Lion’s mane mushroom promotes the biosynthesis of nerve growth factor

A study published in Mycology finds that Lion’s mane mushroom (Hericium erinaceus) synthesizes two very important compounds for nerve growth – Hericenones and erinacines. These compounds are derived from the fruiting body and mycelium of the mushroom. Both compounds promote the biosynthesis of nerve growth factor (NGF) and therefore have value in the prevention and treatment of dementia.

Scientists have isolated two erinacine derivatives and two erinacine diterpenoids (Cyatha-3 and 12-diene with isomer) that promote NGF. Scientists have also demonstrated NGF-stimulating activity from three other compounds in Lion’s mane – Hericenones C, D and E. One of the compounds, 3-Hydroxyhericenone F, showed protective activity against endoplasmic reticulum stress-dependent Neuro2a cell death.

Two other species of the mushroom contained several compounds that promote nerve growth factor. Sarcodon scabrosus (A-F) and Sarcodon cyrneus (A-I, P, Q, J, R, K) all show promise for prevention and treatment of cognitive decline.

Interestingly, both the Hericenones and erinacines are low-molecular weight compounds that cross the blood-brain barrier with ease. The lion’s mane mushroom was designed at the molecular level to positively affect the brain and heal the nervous system, promoting peripheral nerve regeneration and advancing learning abilities into old age.

High blood sugar levels harden arteries, increasing risk of dementia

While there are ways to reverse cognitive decline through medicinal foods, the prevention of dementia should always be approached through a holistic perspective. When treating dementia, it’s equally important to eliminate the chemicals that are promoting cognitive decline. High blood sugar levels are known to harden the arteries, increasing the risk of blockages in the brain. Obstruction of blood flow to the brain can inhibit blood supply to the nerve cells, resulting in impaired brain function.

A study published in the Nutrition Journal found an association between regular consumption of sugary beverages and dementia risk. The study found that free sugars in beverages can increase dementia risk by upwards of 39 percent. The study included a dietary analysis from 186,622 participants from the UK Biobank cohort. The analysis spanned 206 types of food and 32 types of beverages consumed over the course of 10.6 years. The analysis found a correlation between fructose, glucose and sucrose (table sugar) and dementia risk. The free sugars in soda, fruit drinks and milk-based drinks were strongly related to dementia risk, while the sugars in tea and coffee showed minimal risk.

Herbal teas – including but not limited to: green tea, chamomile, lavender and lemon balm – are all wonderful alternatives to sugar-laden drinks. These beverages, when sweetened with plant-based stevia extract, also provide the body with antioxidants, polyphenols and theaflavins that fight free radicals and therefore protect the brain.

Dementia doesn’t have to plague the population and dumb down the people who are running our government and institutions. Advanced learning can continue into old age. Herbal teas can replace sugary beverages in the diet, thus protecting the brain. Medicinal foods like lion’s mane mushroom can heal damaged neurons while promoting new neuron growth.

Lion’s Mane Mushroom – Unparalleled Benefits for Your Brain and Nervous System


Lion’s Mane is nature’s gift to your nervous system! It’s the only mushroom possessing not one but TWO potent nerve growth factors, showing potential benefits for Parkinson’s and Alzheimer’s disease, mild cognitive impairment, multiple sclerosis, leg cramps, anxiety and more.

What if there were one natural treatment that could restore brain function, regrow damaged nerves and reverse the progression of multiple sclerosis? There may be! Lion’s mane mushroom has been used medicinally in Asia for centuries, but for some reason it’s one of the best-kept secrets in the West.

Besides being called “lion’s mane,” Hericium erinaceus, is known by several other names including bearded tooth mushroom, bearded hedgehog, bearded tooth fungus and others. In Japan, it’s known as yamabushitake, which means “mountain priest mushroom.” It has a variety of other names, depending on the country.

In Asia, it is said that lion’s mane gives you “nerves of steel and the memory of a lion,” and from what science is revealing, that’s apt prose. Thus far, evidence exists that lion’s mane mushroom confers the following health benefits:

  • Improved cognitive function

  • Nerve regeneration, remyelination, and increased Nerve Growth Factor (NGF)

  • Improved digestive function and relief from gastritis

  • Immunosupportive, anti-inflammatory, antioxidant

  • Anticoagulant; mild ACE inhibitor; improved lipid profile

The science about lion’s mane is in its infancy, but evidence already points to unparalleled therapeutic benefits for numerous diseases of the central and peripheral nervous system, summarized in the table below, and the list seems to be growing by the day.

Conditions That May Benefit from Lion’s Mane Mushroom

Dementia and mild cognitive impairment (MCI)

Parkinson’s disease

Peripheral neuropathy

Muscle cramps and spasms

Multiple sclerosis (MS)

Stroke recovery

Seizures and seizure-like post-stroke episodes

Anxiety andDepression

Mother Nature’s First “Smart Mushroom”

According to world renown fungi expert Paul Stamets, lion’s mane may be the first “smart mushroom,” providing support specifically for cognitive function, including memory, attention and creativity. It is reported that Buddhist monks have consumed Lion’s mane tea for centuries before meditation in order to enhance their powers of concentration.

This unique fungus contains a group of compounds that regenerate myelin along the axons, which opens the door to a world of neuroprotective benefits.

In one of the few human studies to date, older adults with mild cognitive impairment were given 250 mg powdered lion’s mane three times a day for 16 weeks and compared to another group receiving a placebo. The lion’s mane group scored significantly higher on the cognitive function scale compared with placebo, with no adverse effects. This study should prompt scientists to investigate the therapeutic efficacy of these fungi for dementia patients.

Lion’s Mane Mushroom – Unparalleled Benefits for Your Brain and Nervous System

Lion’s Mane Regenerates Nerves and Stimulates NGF

One of the reasons for his mushroom’s exceptional neuroprotective powers is its ability to stimulate synthesis of Nerve Growth Factor (NGF). NGF is a protein that plays a major role in the maintenance, survival and regeneration of neurons in both your central and peripheral nervous systems. Lion’s mane contains two unique types of compounds, hericenones and erinacines. The erinacines found inHericium erinaceus mycelium are among the most powerful NGF inducers in the natural world, able to cross your blood-brain barrier and stimulate production of new neurons within the brain itself.

With many neurological disorders, the brain is unable to manufacture NGF—in fact, this is thought to be one of the primary mechanisms underlying Alzheimer’s disease. Making matters worse, myelin sheaths and the blood-brain barrier prevent your body from accessing external sources of NGF, and this contributes to the progressive deterioration of brain neurons over time.

Lion’s mane is the only mushroom to demonstrate significant potential for nerve regeneration. In a groundbreaking 2014 study, an oral extract proved effective in promoting peripheral nerve regenerationafter surgically-induced crush-injuries in rats.

NGF also plays important roles in myelination, including protecting oligodendrocytes (myelin-producing cells) and the production of BDNF (Brain-Derived Neurotrophic Factor). In 2003, lion’s mane extract was found to stimulate nerve myelination, which was confirmed by a later study (2013). This finding has huge implications for helping individuals with multiple sclerosis, a disease characterized by progressive demyelination.

As an aside, there is actually another mushroom that may prove helpful with demyelination—Phellinus igniarius, otherwise known as willow bracket. One study found its extract suppressed demyelination as well as suppressing many of the immune cells active (or overactive) in multiple sclerosis.

Amyloid Plaques, Anxiety and Depression

Lion’s mane has also been shown to reduce beta-amyloid plaques. Beta-amyloid plaques are proteins that form in the fatty membranes that surround nerve cells, interfering with neurotransmission. These plaques are thought to play a role in neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

In a compelling animal study, mice were injected with neurotoxic peptides (to induce plaque formation), in order to assess the effects of lion’s mane on the type of amyloid plaque seen in Alzheimer’s sufferers. As the plaque developed, the mice lost their ability to memorize the maze, but when they were fed a diet containing lion’s mane mushroom, their performance in the maze significantly improved. In addition to regaining their former cognitive skills, they gained NEW cognitive skills—something akin to curiosity, as measured by greater time spent exploring novel objects compared to familiar ones. The reduction of beta amyloid plaques in the mushroom-fed mice was remarkable.

Lion’s mane also shows potential in the treatment of anxiety and depression. In a study involving menopausal women, the mushroom reduced depression and anxiety by some mechanism other than its NGF-enhancing properties. The effects were particularly strong in lowering anxiety, reducing feelings of “irritation” and enhancing concentration. So the Buddhist monks were right!

Benefits Beyond the Nervous System

As with many mushrooms, lion’s mane has a number of other therapeutic actions resulting from itsanti-inflammatory and immunosupportive properties, including the following:

  • Cancer: One animal study found an extract of lion’s mane inhibited the spread of colon cancercells to the lung by 66 to 69 percent; the mushroom has also been shown to induce apoptosis inleukemia cells and inhibits angiogenesis

  • Thrombosis: Hericenone B appears to “potently and specifically inhibit collagen-induced platelet aggregation”

  • Mild ACE Inhibitor: The exact molecule underlying this effect is not currently known, but it is thought to be a bioactive peptide

  • Lipids: Reported to reduce triglycerides and improve LDL and HDL levels (lion’s mane mycelium, specifically)

  • Fat Metabolism: Increases the expression of several genes involved in fat metabolism

  • Wound Healing: Topical application of the extract was found to accelerate wound healing

Lion’s mane mushroom has earned its right to be in your kitchen pantry and medicine cabinet. I’m sure we’ll be seeing many more studies illuminating its therapeutic potential in the near future.

Although the mushroom’s availability is limited to hardwood forests and a few gourmet food shops, kits are available that allow you to grow your own lion’s mane at home. Lion’s mane mushrooms are 20 percent protein and can be prepared using standard culinary techniques, just like any other edible mushroom. Mushroom Forager describes this oddball’s appearance as sort of like a “faceless hedgehog,” or a truffula tree out of The Lorax—so, they’re rather easy to spot. Does it taste like chicken? No, in this case lobster… or so they say, as I’ve not partaken myself.

According to Mushroom Forager:

“Lion’s mane has no look-alikes, edible or poisonous, and all forms are edible and delicious in the kitchen.”

You’ll will find lion’s mane in the forests of North America, Europe and Asia during the summer and fall, typically attached to dead or dying hardwood trees and logs, including maple, beech, oak, birch, walnut and sycamore. Lion’s mane is also widely available as a supplement and comes in powders and liquid extracts. Some serious allergic reactions have been reported, so please take ample precautions.
