Selenium—a mineral found in many foods—could reverse the cognitive impact of stroke and boost learning and memory in aging brains, according to University of Queensland research.
Queensland Brain Institute (QBI) lead researcher Dr. Tara Walker said studies on the impact of exercise on the aging brain found levels of a protein key to transporting selenium in the blood were elevated by physical activity.
"We've known for the last 20 years that exercise can create new neurons in the brain, but we didn't really understand how," Dr. Walker said.
The research team investigated whether dietary selenium supplements could replicate the effects of exercise.
"Our models showed that selenium supplementation could increase neuron generation and improve cognition in elderly mice," Dr. Walker said.
"The levels of new neuron generation decrease rapidly in aged mice, as they do in humans.
"When selenium supplements were given to the mice, the production of neurons increased, reversing the cognitive deficits observed in aging."
Selenium is an essential trace mineral absorbed from soil and water and is found in foods such as grains, meat and nuts, with the highest levels found in Brazil nuts.
The scientists also tested whether selenium would have an impact on the cognitive decline sometimes experienced following stroke, which can affect people's memory and ability to learn.
"Young mice are really good at the learning and memory tasks, but after a stroke, they could no longer perform these tasks," Dr. Walker said.
"We found that learning and memory deficits of stroke affected mice returned to normal when they were given selenium supplements."
Dr. Walker said the results opened a new therapeutic avenue to boost cognitive function in people who were unable to exercise due to poor health or old age.

My geologist brother told me a few years ago to take daily selenium supplements. He said our soil is not as mineral-rich as it used to be so we can’t get it from food alone.
I have to give it to our cows to keep them healthy.
Seems to correspond to where the glaciers used to be. Was your land covered in ice 10,000 years ago? Probably low in selenium.
Be Careful with Brazil Nuts and Selenium Poisoning
"If you eat too many Brazil nuts, you may end up suffering from selenium poisoning. Brazil nuts are rich in selenium, and there is about 544 mg of selenium in 1 ounce of serving. Selenium is a micronutrient that is required by the body only in trace amounts. It is essential to the body for the production of selenoproteins which are enzymes that play a major role in the regulation of the immune system and the thyroid gland.
My mom the nurse tried to make sure a neighbor approaching dementia ate a Brazil nut every day.
The ability to give mice strokes for study may be useful for the eradication of rodents.
So how exactly do “young mice” suffer a stroke? Does it happen a lot or do the researchers cause it? 🤬
My doctor put me on it last year.
No! The only way to be healthy is to take experimental vaccines and pills made out of chemicals in a laboratory by big pharma! How dare you seek health from God’s natural remedies!
I’m trying to imagine the tiny CAT scan machines they must have to see if the mice have had a stroke.
It must be very scary for a mouse to be put in a CAT scan as well.
The guy nearly died before Dr. House realized that they don't call Brazil nuts Brazil nuts in wait for it BRAZIL!!!
The water from the spring by by my grandmother’s house was tested by my sister, a water expert. It contained selenium.
My mother and my grandmother could remember everything when they were in their 80 and 90’s and could still drive a car.
Probably had the vaxx and a couple of boosters. /s
Eat fish
I tried Selenium and quickly came down with high cholesterol.
