Correlation is far from demonstrating causation, especially in this case. People often “self medicate” – they tend to gravitate to leisure activities that they find rewarding. People that find mainstream TV shows painfully inane aren’t going to be spending their free time watching them.
But it is interesting about the standing desk, the war on sitting because of the mortality implications… but curling up on the couch for some TV gets a pass?
Using a special mix of small molecules, two groups of scientists in China have successfully turned human skin cells into neurons. They hope that their technique could one day help rejuvenate failing tissues in the brains of Alzheimers patients.
It’s interesting that a mice and human trial were done seemingly in parallel. It’s apparently cheap, easy, and minimal if any rejection risk. But we’re a ways from being able to leverage this into something useful.
Today we hear a great deal about Alzheimer’s disease, but relatively little about its discoverer. Its discoverer had little idea how famous his few case studies would become. Here’s how Alzheimer’s went from a medical anomaly to one of the most known and feared medical conditions in the world.
A surprising study contradicting all previous research found that being fat in middle age appears to cut the risk of developing dementia rather than increase it, the Lancet scientific journal has reported.
A study of two million people found that the underweight were far more likely to develop dementia, a growing problem among the elderly in the Western world.
Underweight people had a 34 percent higher risk of developing dementia than those of a normal weight, the study found, while the very obese had a 29 percent lower risk of becoming forgetful and confused and showing other signs of senility.
Obesity or dementia? Superficial outward beauty accompanied by the brain of a mouse, or a healthy mind that shall not know happiness due to the cruel world’s shallow condemnation of your size? Total satisfaction is as impossible as squeezing a slippery water balloon—whichever side you get a solid grasp on will only cause the opposite side to swell in grotesque proportion.
There is some belief that dementia may be caused by a lack of myelin (fatty substance) covering the meninges in the brain/CNS. I think it’s also true that children with a certain degenerative brain disease (can’t remember what it’s called) are told to eat a ketogenic diet (fatty foods, specifically olive oil) to slow the destruction of the myelin and therefore the meninges.
Internet brain games aren’t the only way to gauge what’s going on between your ears. A simple physical test may be able to tell you how healthy your brain is, according to a new study from Japan, published in the journal Stroke.
In the study, researchers had 1,387 healthy people stand on one leg with their eyes open for as long as possible, up to a minute. Then they performed MRI’s on the subjects, whose average age was 67, and had them complete four cognitive tests.
Interestingly, the length of time the people could balance predicted what the scientists saw on the brain scans: Those who were unable to stand flamingo-style for more than 20 seconds were more likely to have cerebral small vessel disease, a condition where tiny blood vessels deep in the brain are damaged. None of the study participants showed any symptoms.
Just another reason to be self-conscious in yoga class… But seriously consider the following:
Flunk the test? Ask your doctor if you should be concerned, and take a proactive approach to brain health. “People say, ‘What can I do to keep from getting Alzheimer’s? What can I do to prevent stroke? If it’s good for your heart, it’s good for your brain,” says Senelick. “Work on your risk factors: hypertension, diabetes, poor diet, lack of exercise, smoking.”
Are you a vegetarian or a vegan? Besides vitamin B12, depending upon what you eat and the supplements you take, you can find your diet somewhat low in zinc, long chain omega 3 fatty acids, and even some amino acids. One of these amino acids is called creatine, and the best source is meat.
Researchers who study cognition and athletic performance simply love giving vegetarians creatine supplements. This practice might seem curious until you look at the following facts…
Most people don’t understand about non-essential amino acids is that you don’t need them – your body can synthesize them. Just not efficiently. Unless you’re getting your non-essential aminos from your food or supplements – you’re probably non-essential amino acid deficient.
