Stressed out? You may be at a higher risk for Alzheimer’s disease. You’re probably wondering to yourself how that is possible. Highly intelligent people who use their brains all of the time, like scientists, CEOs, and presidents, deal with stress on a day to day basis. The truth is that lack of higher education or brain activity is not the only major cause of dementia.
If keeping your brain active is a good way to prevent cognitive decline, then why did people such as Ronald Reagan and Norman Rockwell develop Alzheimer’s disease? The answer is stress. Recent studies have shown that people who deal with high levels of stress in their career or their family life are more likely to develop dementia. Stress cannot be said to directly cause dementia, but it is a trigger for the degenerative process in the brain.
An Argentine research team examined 118 patients with Alzheimer’s disease and 81 healthy individuals whose age, gender, and educational level were comparable to the Alzheimer’s patients. Both groups were questioned about the amount of stress that they had faced in the past three years. The researchers reported that 72% of the Alzheimer’s patients admitted to coping with severe emotional stress or grief, such as the death of a loved one or financial problems. This was nearly three times as many as the control group.
A man or a woman could be of above-average intelligence, well-educated in medicine and psychology, and understand that every statistical measurement of personality and temperament can be distributed across a bell-curve in a large enough population. He or she could comprehend the determining power of genetics, the impact of cultural influence on belief systems, and how neuroplasticity molds our mental processing to respond to environmental stimuli.
A clever, sophisticated professional could understand all of this, yet still believe that somehow, all members of the opposite sex are manipulative and irrational. Not some, all 3.5 billion of them. Why?
Perhaps throughout his or her life, this person has made irrational decisions to socialize with very irrational and emotional people of the opposite sex, and through these experiences has thus formed a gender bias. Research shows we tend to mostly place people into categories of gender, race, and age. This task is so pervasive that scientists have deemed it our “primitive” categorization.
Once we’ve made up our mind about a group, or even someone in particular (consciously or not), it’s often hard to change our opinion. When beliefs are formed, confirmation biases kick in and begin to look for information that supports our views, and selectively ignore everything which doesn’t. Maybe someone had decided that you were shy and uptight when you first met. You were more reticent than usual because you had only gotten 3 hours of sleep the night before. Now that acquaintance may not notice all the times you’re friendly and outgoing, but instead seems to pounce on all the times you’re a little quiet.
Are carbohydrates holding us back from our true potential? Exploring the possibilities of a ketogenic diet.
It is hard to avoid carbohydrates in the world we live in today, where since the industrial age 100-200 years ago, factories have been able to produce large quantities of sugar and white flour to feed the masses. Really though, foods high in carbohydrates (such as pasta, bread, rice, and potatoes) have only been available to us since the rise of agriculture, approximately 5-10,000 years ago. Prior to that, humans assumed a hunter-gatherer lifestyle where our diets consisted primarily of animal products and low starch vegetables, basically whatever we could find in nature without growing ourselves.
What if you were able to erase all of your painful memories by simply taking a pill? While this might sound like something out of a sci-fi film, a recent study conducted by a group of researchers at MIT suggests that it may be possible in the future.
The researchers say that they’ve identified a gene known as Tet1 that appears to be important in the process of “memory extinction.” Memory extinction is the natural process of older memories being overridden by newer experiences. In this process, conditioned responses to stimuli can change: what once elicited a fearful response doesn’t always need to if the danger has ceased.
In the study, researchers compared normal mice to mice without the Tet1 gene. The researchers conditioned all of the mice to fear a particular cage where they received a mild shock. Once the memory was formed, the researchers then put the mice in the cage but did not shock them. After a while, mice with the Tet1 gene lost their fear of the cage as new memories replaced the old ones. However, mice lacking the Tet1 gene remained fearful.
It’s almost time for the dreaded fall midterms. Somehow, midterms manage to be even more stressful than finals. Maybe it’s because of the time of year they fall, which is easily the most beautiful time to be living in Boston. You just want to spend time outside walking on the esplanade, looking at the beautiful red and orange leaves on the trees that line the river and watching the rowing teams pass you by. Well, it may actually be beneficial to take some time out of your studying to take a stroll along the river, or to just sit on a bench for a little while. In fact, take some time to picnic this fall with some brain food, because studies show that it will enhance your studying experience.
Some of these brain foods include foods that you’d expect. These are the foods that your mom has been forcing down your throat, whether you like them or not, for as long as you can remember. But take a step back and think about why. Berries, for example, provide neurological benefits. They have a ton of antioxidants which will protect you from bacteria that make you sick when you’re stressed. Berries mediate signaling pathways that are involved in cell survival, and they increase the neuroplasticity, neurotransmission and calcium buffering properties of the brain, all related to aging, and in turn, memory and behavioral changes.
If you’ve ever seen someone with a baby, chances are you’ve heard them say something along the lines of “You’re so cute; I could just eat you up!”
Well a recent article published in Frontiers in Psychology by a research team at the Technische Universität of Dresden, Germany shows there may be a link between an infant’s smell and a female’s response, depending on the status of the female. Scientists have studied the connection between olfactory signals and the bond between a mother and her infant in several non-human mammal species. However, up until now, the research performed on mother-infant bonding in humans has only ever explored the visual and auditory senses.
What they did:
A total of 30 women were tested. Fifteen of the women had given birth for the first time three to six weeks prior to the experiment (primiparous). The other 15 women had never given birth (nulliparous). To obtain the sample odors, 18 infants each wore a T-shirt for two nights postpartum. The shirts were then placed in plastic bags and frozen to keep the odor unaltered. During the experiment, each woman was exposed to both “odorless” air and the odors of two different infants; primiparous women were never exposed to their own baby’s odor. The women were asked to rate the odor on intensity, familiarity, and pleasantness, though none of the participants were aware of what the odor stimulus was. As the women processed the different odors, an fMRI machine scanned their brain.
In the last century, treatment of social and learning disabilities has drastically changed. Through the Individuals with Disabilities Education Act, every student who qualifies for special education is entitled to a free and appropriate public education, delivered through an individualized education plan. An ‘IEP’ is designed through the collaboration of parents, teachers, and special education specialists. The largest category of learning disability is the specific learning disability, of which dyslexia is a typical example.
The amount of care put into special education has drastically changed the lives of many individuals, however, special education excludes those who have a learning disability due to economic situations. This reflects a longstanding social and educational belief that learning disabilities are innate, the result of genetic predisposition and not due to upbringing. The prevailing paradigm did not believe that upbringing could have a significant effect on the development on the brain.
To little surprise, neuroscience is showing otherwise.
We have always known that acute incidents can have a significant effect on brain development and function (such as in the effects of repeated physical trauma on function), but recent research is suggesting that external factors during development, including many associated with poverty, can have significant, long-term effects. These factors include higher levels of environmental toxins, lower nutritional levels, and increased levels of parental neglect. Recent research suggests that external factors, including poverty, can have significant internal effects on the brain, including brain development and function. Poverty affects the development of the brain in multiple ways, including through poverty-associated factors such as higher environmental toxins, lower nutritional levels, and higher levels of parental neglect. However, the research of Gary Evans and Michelle Schamberg of Cornell University indicates that solely the added stress of low socioeconomic status is responsible for these effects.

What do you want? What do you need? Food? Water? Shelter? Sure, sure, yes maybe, but what do you want? Dream bigger, you’re thinking too realistically! Stop limiting yourself, open up! Close your eyes, relax, paint the picture how you see it. Don’t tell me, just visualize it, taste it, feel it! C’mon man, it’s in there somewhere! Yes Yes, exactly bottle up all those ‘it’s not gonna happen’ or ‘yeah right’ moments you experienced and strangle the life out of them! You want the Arancio Argos Lamborghini Aventador LP 700-4 with the matte wheels to match, okay. You liked that bachelor pad in Phuket didn’t you? The one with the wrap around balcony, snug love seat, black leather couch, gourmet kitchen, his/her bathrooms…yeah that’s the one. But how? That’s impossible right? How do you expect to reward yourself with such prodigal riches at such a young age? Who are you trying to follow? Me: Floyd “Money” Mayweather, Adrien Broner, Scott Disick, Lavish P! Because we’re all rich peasants! If you can’t afford to roll with the crew baby, then you’re merely a campesino (shout out to to the Spanish readers). We get everything we want! There ain’t no morality in this [bleep]! We might as well call ourselves the seven deadly sins! We take pride in our beliefs, feed off of your envy, consume more than we require, lust in the beauty of those we surround ourselves with, avoid physical labor, laugh at your anger, and most importantly: ignore the realm of the spiritual because its not worth a dime! Now, I love me some greed in the morning, especially served with a bowl of lucky charms. But is the idea of greed more innate than we think it is? Are the moral perceptions of greed and neuroscience more intertwined than we think? Shall we…
Researchers from the U.S. Department of Energy’s Brookhaven National Laboratory and Thomas Jefferson National Accelerator Facility, Oak Ridge National Laboratory, Johns Hopkins Medical School, the University of Maryland, and Weizmann Institute’s Neurobiology Department have all developed new and improved brain scanning techniques. These new methods allow scientists to monitor brain activity in fully-awake, moving animals.
At Brookhaven, researchers combined light-activated proteins that stimulate specific brain cells, a technique known as optogenetics, with positron emission tomography (PET) to observe the effects of stimulation throughout the entire brain. Their paper in the Journal of Neuroscience describes this method, which will allow researchers to map exactly which neurological pathways are activated or deactivated downstream by stimulation in specific brain areas. Hopefully, following these pathways will enable researchers to correlate the brain activity with observed behaviors or certain symptoms of disease.
The Pasteurian Revolution of the 1800′s heralded in a new paradigm of disease. Previously unexplained health phenomena could now be shown to be derived from “germs” – microorganisms invisible to the naked eye. The term “germ” quickly took on a negative connotation and until recently the microbial world has been seen primarily as a breeding ground for invisible enemies to human health. Its pretty incredible actually, the distaste the word “bacteria” instills in us, when really, it simply refers to a domain of prokaryotes. So, is the entire microbial world bent on our demise? I think the answer to this question can be summed up in one simple statistic:
Inside of you there are 1013 human cells and 1014 bacteria cells.
In other words, for every one cell of you there are ten that are not you…Wait, what? The first question this recent discovery may fuel is a stumbled WHAT? But lets digress for a moment and ask, why?
