Most of us have had “senior moments” where we’ve run into a friend and momentarily forget their name. Or we search the house for eyeglasses that are perched on our head. Or we walk in circles trying to locate our car in the mall parking lot. Those forgetful moments are fairly typical of being a member of the 21st century with a headful of thoughts and responsibilities.

Putting the car keys in the refrigerator might be something you do if you’re distracted, but storing a dozen cans of pineapple in the dishwasher, or forgetting how to drive home are not normal memory slips. These types of forgetfulness could be a sign of cognitive impairment or a dementia. But the latest research is showing that if you treat early signs of mental decline, you can slow down and possibly reverse cognitive decline.

Ilene Naomi Rusk, Ph.D. is a neuropsychologist, functional brain health coach, and director of The Healthy Brain Program at the Brain and Behavior Clinic (2523 Broadway #200, Boulder, CO, 303-938-9244). Dr. Rusk acts like a detective to fully understand the root causes of a person’s psychological and brain health issues. Then she works with the patient and a functional medicine team with personalized diagnostics, and treatment or interventions, from brain training to nutrition guidance.

“It’s good for everyone to have baseline neuropsychological testing in mid-life even if you have no memory issues,” says Rusk. Most people think cognition is memory, but it’s much more than that. It’s memory, learning, attention and focus, visual and spatial skills, and how we absorb information, retain it and then share it. Cognition is also how we process things visually, auditorily, and spatially.”

There are different categories of cognitive health versus cognitive impairment that can clue me into whether or not someone is headed towards dementia, says Rusk.

“Subjective Cognitive Impairment (SCI) is when you notice a change in your cognition and think ‘I’m a little different than I used to be’, but other people can’t tell and it wouldn’t show up on a memory test.

“The next category is Mild Cognitive Impairment (MCI). This is when you notice changes in your thinking and people around you may or may not notice changes. With MCI you might also have some challenges on neuropsychological tests that show empirical changes. This is a staging system,” says Rusk. “With MCI there’s a great opportunity to intervene, and we want to intervene as early as possible because once you have Mild Cognitive Impairment it’s easier to slip into dementia,” she adds.

The best thing is to tell your doctor if you have concerns and then go to see someone to get properly assessed.

“I recommend that people go directly to a neuropsychologist or neurologist after they’ve spoken to their family physician to look for root causes. There are so many prevention strategies and a new functional medicine methodology to approach cognitive decline. Functional Medicine practitioners look at blood sugar control, blood pressure, gut health, latent, mold, infections, inflammatory markers, stress, sleep patterns, chronic loneliness, and trauma. These are all important things when looking at modifiable root causes of cognitive impairment,” says Rusk.

“We no longer think that Alzheimer’s is only a disease of the brain. That’s definitely an endpoint,” she says. “Everything from dental health to herpes is being looked at, and the amyloid theory of Alzheimer’s is even being questioned by some people. I see trauma healing and stress reduction as important interventions. Chronic stress affects so much in our physiology and unhealed trauma leaves physiologic imprints.

 It’s also important to know,” she adds, “that 70% of dementias are of the Alzheimer’s type and 30% of dementias fall into other categories such as Frontal Temporal Dementia, Parkinson’s, Lewy Bodies, etc. getting properly diagnosed is very important.

The brain pathology of Alzheimer’s often starts 20 years before there are clinical signs. “A person goes from no dementia to SCI, MCI, early stages of dementia, mild, moderate, and severe stages,” says Rusk. “My goal is prevention, and my favorite thing to do is talk to young people about brain health. If we can intervene early, the decline can be delayed and even sometimes prevented.”

Mushrooms may reduce risk of mild cognitive impairment by 50%

Mushrooms - morchella mushrooms, boletus mushrooms, oyster mushrooms, on white background.If  you eat golden, oyster, shiitake and/or white button mushrooms, as well as dried and canned mushrooms, you’re in luck! A team from the Department of Psychological Medicine and Department of Biochemistry at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS) has found that seniors who consume more than one and one-half cups of mushrooms weekly may reduce their odds of having mild cognitive impairment (MCI) by 50%. 

What is MCI?

Mild cognitive impairment causes cognitive changes that are serious enough to be noticed by people experiencing them or to other family and friends. The changes are not severe enough to interfere with daily activity. People with MCI that involves memory problems are more likely to develop Alzheimer’s disease or other dementias than people without MCI. Approximately 15-20 percent of people age 65 or older have MCI.

Mushrooms might be a key to reducing MCI

The correlation between eating mushrooms and reducing risk of MCI is surprising and encouraging, according to Assistant Professor Lei Feng, who is from the NUS Department of Psychological Medicine, and the lead author of this work.

The six-year study, which was conducted from 2011 to 2017, collected data from more than 600 Chinese seniors over the age of 60 living in Singapore. The research was carried out with support from the Life Sciences Institute and the Mind Science Centre at NUS, as well as the Singapore Ministry of Health’s National Medical Research Council. The results were published online in the Journal of Alzheimer’s Disease on 12 March 2019.

The researchers found that the compound called ergothioneine (ET), a unique antioxidant and anti-inflammatory which humans are unable to synthesize on their own, is the key to possibly reducing MCI. Ergothioneine is found in liver, kidney, black beans, kidney bean and oat bran. But the highest levels are found in bolete and oyster mushrooms.

Other compounds contained within mushrooms may also be advantageous for decreasing the risk of cognitive decline. Certain hericenones, erinacines, scabronines and dictyophorines may promote the synthesis of nerve growth factors. Bioactive compounds in mushrooms may also protect the brain from neurodegeneration by inhibiting production of beta amyloid and phosphorylated tau, and acetylcholinesterase, the culprits of Alzheimer’s disease.

How much do you need to eat?

In the study, a portion was defined as three quarters of a cup of cooked mushrooms with an average weight of around 150 grams. Two portions would be equivalent to approximately half a plate. While the portion sizes act as a guideline, it was shown that even one small portion of mushrooms a week may still be beneficial to reduce chances of MCI.

An article in Science Daily said this: According to Robert Beelman, professor emeritus of food science and director of the Penn State Center for Plant and Mushroom Products for Health, it’s preliminary, but you can see that countries that have more ergothioneine in their diets, countries like France and Italy, also have lower incidents of neurodegenerative diseases, while people in countries like the United States, which has low amounts of ergothioneine in the diet, have a higher probability of diseases like Parkinson’s Disease and Alzheimer’s,” said Beelman. “Now, whether that’s just a correlation or causative, we don’t know. But, it’s something to look into, especially because the difference between the countries with low rates of neurodegenerative diseases is about 3 milligrams per day, which is about five button mushrooms each day.”

 

Mushroom recipes

Cooking mushrooms does not seem to significantly affect the compounds. Roasted or baked mushrooms are simple to make and delicious, and go well with most foods as a side dish or topping.

Wash and slice musthrooms. Lightly oil shallow baking pan large enough to hold mushrooms in single layer. Add mushrooms and toss with 2 to 3 tablespoons oil. Add garlic; season with salt; roastfor 20 minutes stirring on occasion; mushrooms should be browned. Season with pepper.

For baked mushrooms with parmesan, thyme and lemon simply toss with olive oil, Paremesan cheese, garlic, thyme, lemon zest and lemon juice.

For more mushroom recipes google for mushroom risotto, mushroom gravy, cream of mushroom soup, creamy mushroom pasta, mushroom and barley soup.
