COFFEE CAUSES CANCER!!!   Wait, not so fast. You might have seen that CA Judge Elihu Berle has ruled that coffee shops, convenience stores and others selling coffee must publicly post in each location that it contains a carcinogen named acrylamide. Background Here’s the Cliff Notes version of a complex story. In 1986, CA passed Prop 65, which required retailers and others to post a list of any toxic materials that someone might be exposed to while in their store. The list must be easily visible. Since a lot of stuff is toxic in large quantities-e.g-aspirin- or a lot of common household products are toxic if consumed – e.g.- Clorox- the list of dangerous products that could be in a clothing store or coffee shop quickly became enormous. (Probably defeated the original purpose of Prop 65, but that’s a different discussion). What’s “acrylamide”? You probably consume some every day. Any time a starch is cooked at over 250 degrees, acrylamide is produced. French fries. ...

This brain builder is so good that we are quoting the title as published in a prestigious scientific journal : “Playing Super Mario 64 increases hippocampal grey matter in older adults.” It seems that some researchers from Montreal and St. John’s Newfoundland have nothing better to do than play video games. Well, not exactly. Gregory L. West, PhD and Benjamin Rich Zendel PhD, put together a research team to see if the brains of older adults would benefit from playing video games and, if so, exactly how. The team from the Faculty of Medicine at Memorial University of Newfoundland and from the Centre de Researche en Neurologie et Cognition at the University of Montreal, recruited 33 adults from ages 55 to 75. They used the standard test method with a control group and subject groups. The control group continued their normal activities. A second group took self-directed piano lessons (as we’ve covered before, research shows notable brain growth from learning to play a musical in...

While you sleep, your glymphatic system shampoos your brain. It gives it a good cleaning and eliminates any toxins or bad stuff that has managed to slip in. Of course, your brain is performing an endless number of other functions as well. But the cleaning function is different in that it only is performed while you sleep. And if you don’t sleep enough, well, you’re trying to do your waking tasks with a clogged-up, messy, dirty brain. It is possible- although speculative at this point- that there may be a link between inadequate sleep and Alzheimer’s disease. Enough’ s Enough How much sleep do you need? We came across a newsletter from the Cleveland Clinic with some information on appropriate amounts of sleep that referenced guidelines from a variety of sources including National Sleep Foundation, American Academy of Pediatrics and the American Academy of Sleep Medicine. Obviously, infants and babies sleep most of the time, furthermore, they need to. Toddlers (ages 1-3) need 12...

A good night’s sleep may help you manage fear and risks better. A study just posted in Journal of Neuroscience describes the importance of a good night’s sleep to controlling strong emotions, especially fear. Previous studies in this area attempted to discover what happens in the brain after a frightful experience.  These prior studies, for example, show how Post-Traumatic Stress Disorder (PTSD) affects sleep. A team at the Rutgers University Center for Molecular and Behavioral Neuroscience, led by Itamar Lerner, has taken a different approach. They wanted to see if there is a relationship between adequate sleep and prevention or management of the brain’s reaction to subsequent stressful events. Research Team Lerner is a Postdoctoral Fellow in sleep research. Along with fellow researchers Neha Sinha-also doing Postdoctoral research-in her case in brain imaging, Shira Lupkin and Alan Tsai, they used new technology that allows mobile tracking of sleep habits over a per...

If you do it right, puzzles and games might just save your brain. There are millions of players of strategy games, memory games, word games and puzzles. They want to know that working crosswords, solving sudoku, playing bridge, mahjong or chess will help preserve mental acuity. Some are counting on it. Cognitive Reserve Cognitive reserve is the term developed after researchers found instances of examination of the brains of individuals that showed signs of dementia or Alzheimer’s disease, but, while alive, the individual had exhibited no signs of dementia.  We want to build cognitive reserve, and there is evidence that puzzles can do that. One key-and positive- study from 2011 found that solving crossword puzzles delayed onset of memory loss by 2.5 years, and may have had much longer beneficial impact. NIH Research The National Institute of Health and the National Institute of Nursing Research funded a study on brain-training and cognition. That study is related-ad...
