A study published in the journal PLOS ONE shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.

While space is full of radiation,…

Big trouble lies ahead if Alzheimer’s is proven to be a form of diabetes

THE human brain evolved to seek out foods high in fat and sugar. But a preference that started out as a survival mechanism has, in our age of plenty, become a self-destructive compulsion. It is well known that bad diets can trigger obesity and diabetes. There is growing evidence that they trigger Alzheimer’s disease too, and some researchers now see it as just another form of diabetes (see “Food for thought: Eat your way to dementia”). If correct, this has enormous, and grave, implications. The world already faces an epidemic of diabetes. The prospect of a parallel epidemic of Alzheimer’s is truly frightening, in terms of human suffering and monetary cost. This outcome will not be easily averted. Few people need to be told that too much high-fat, high-sugar food is a health hazard. And yet sales of fast food remain healthy (or should that be hefty?). Part of the reason is “future discounting”, another evolved feature of the human brain that makes us value short-term rewards over long-term risks.

Does it mean this stuff is a powerful anti aging drug?

A new study conducted by researchers at Children’s Hospital & Research Center Oakland shows that a century-old drug, methylene blue, may be able to slow or even cure Alzheimer’s and Parkinson’s disease.
Used at a very low concentration – about the equivalent of a few raindrops in four Olympic-sized swimming pools of water – the drug slows cellular aging and enhances mitochondrial function, potentially allowing those with the diseases to live longer, healthier lives.
Dr. Atamna’s research found that methylene blue can prevent or slow the decline of mitochondrial function, specifically an important enzyme called complex IV. Because mitochondria are the principal suppliers of energy to all animal and human cells, their healthy function is critical.
“The results are very encouraging,” said Dr. Atamna. “We’d eventually like to try to prevent the physical and cognitive decline associated with aging, with a focus on people with Alzheimer’s disease.
Also impressed is one of Dr. Atamna’s co-authors, Bruce Ames, PhD, a senior scientist at Children’s and world-renowned expert in nutrition and aging. “What we potentially have is a wonder drug.” said Dr. Ames. “To find that such a common and inexpensive drug can be used to increase and prolong the quality of life by treating such serious diseases is truly exciting.”
Dr. Atamna’s research is the first to show that low concentrations of the drug have the ability to slow cellular aging in cultured cells in the laboratory and in live mice. He believes methylene blue has the potential to become another commonplace low-cost treatment like aspirin, prescribed as a blood thinner for people with heart disorders.
