Is exercise actually good for the brain?
There are plenty of reasons to get off your duff and exercise—but is improving your brain one of them? The U.S. Centers for Disease Control and Prevention touts exercise as a way to “
boost brain health
,
” while the World Health Organization suggests that about 2 hours of moderate activity or 75 minutes of vigorous activity per week can
help improve thinking and memory skills
.
But new research reveals a more complex picture. One recent review of the literature suggests
the studies tying exercise to brain health may have important limitations
, including small sample sizes. Othe...

Establishing metrics and control laws for the learning process: ball and beam balancing.
This study provides an example of how mathematical analysis together with careful experimental observations can shed light onto the early stages of skill acquisition. Since the difficulty of this task depends on the length of the beam, ball and beam balancing tasks may be useful for the rehabilitation of children with dyspraxia and those recovering from a stroke.

The Director of the NIH Lays Out His Vision of the Future of Medical Science
Our world has never witnessed a time of greater promise for improving human health. Many of today’s health advances have stemmed from a long arc of discovery that begins with strong, steady support for basic science. In large part because of fundamental research funded by the National Institutes of Health (NIH), which traces its roots to 1887, Americans are living longer, healthier lives. Life expectancy for a baby born in the U.S. has risen from 47 years in 1900 to more than 78 years today. Among the advances that have helped to make this possible are a 70% decline in the U.S. death rate from cardiovascular disease ...

The glutathione cycle shapes synaptic glutamate activity Neuroscience
Glutamate is the most abundant excitatory neurotransmitter, present at the bulk of cortical synapses, and participating in many physiologic and pathologic processes ranging from learning and memory to stroke. The tripeptide, glutathione, is one-third glutamate and present at up to low millimolar intracellular concentrations in brain, mediating antioxidant defenses and...

The Four Questions You Should Ask Yourself About Brain Health
I don’t watch much TV, and when I do, I rarely pay attention to commercials. But a new ad caught my eye the other day: in it, a middle-aged accountant talks frankly about his passion for his work. Numbers, he says, just come naturally to him, and he feels like his brain is firing on all cylinders when he’s working at something he loves. Then, the CEO of AARP walks into the frame and announces a new website featuring quizzes, games, and other applications designed to promote the brain health of older Americans.
Having spent a good portion of my career working to make brain health as well-known a term as heart h...

Mapping Traumatic Brain Injuries
There's been an increasing amount of media attention to the topic of Traumatic Brain Injury (TBI) -bolstered in part by conversations surrounding the 2015 Hollywood blockbuster Concussion. The movie Concussion describes a particular phenomenon, Chronic Traumatic Encephalopathy or CTE, which occurs in the brain after repeated high impact blows to the head. The diagnosis of CTE requires examining brain tissue under a microscope after death, so it can't be diagnosed in living individuals. But in fact, there are many types of TBI, with concussion being the mildest (but most common) form. Today, brain mapping techniques are mak...

Reflections on the Future of Medicine
Recently, I traveled through China. I climbed mountains, hiked through forests, crossed deep valleys. I visited cities of every size. I floated across lakes and traveled beautiful shorelines churning with life. As a man of a certain age, I began to compare the permanence of the timeless landscape with the evanescence of my own existence. Yet, as a scientist, I knew these reflections were flawed.
Scientists are trained to think in terms of aeons, millenia, and lifetimes. Consider the paradox. Is it the solid mountain or fragile the forest that is permanent? Is it the massive shoreline cliffs or the teeming shore life that...

Carrie Fisher's Death Highlights The Reality Of Heart Disease In Women
Carrie Fisher died early Tuesday morning, four days after suffering a heart attack on a flight from London to Los Angeles. The actress and author, best known for her iconic role as Princess Leia in the “Star Wars” franchise, was 60 years old.
Experts say that Fisher’s death highlights an important reality about heart disease: It is the leading cause of death among men and women alike in the U.S.
While heart disease encompasses many different conditions, a heart attack occurs when coronary arteries become blocked and oxygenated blood can’t reach the heart. About 735,000 Americans have hea...

The robot suit providing hope of a walking cure
Clothing that can help people learn how to walk again after a stroke is the brainchild of a Harvard team reinventing the way we use robot technologyConor Walsh ’s laboratory at Harvard University is not your everyday research centre. There are no bench-top centrifuges, no fume cupboards for removing noxious gases, no beakers or crucibles, no racks of test tubes and only a handful laptop computers. Instead, the place is dominated by clothing.On one side of the lab stands a group of mannequins dressed in T-shirts and black running trousers. Behind them, there are racks of sweatshirts and running shoes. On another wall of s...

3 Major Health Problems That Disproportionately Affect Vets
Veterans are more likely to report very good or excellent health than their civilian counterparts, so they may not realize that they’re also at greater risk than civilians for some long-term health problems.
Of course, many veterans have acute physical health problems, like wounds and amputations, and trauma-based mental health issues like depression and PTSD. Indeed, mental health issues affect 30 percent of Vietnam veterans, 20 percent of Iraqi veterans and about 10 percent of Gulf War and Afghanistan veterans.
Less known are some of the ordinary, chronic conditions that disproportionately affect ser...

Janet Reno Proved Life Does Not End After A Parkinson's Disease Diagnosis
Janet Reno, the first woman to serve as U.S. attorney general, died Monday from complications related to Parkinson’s disease. She was 78 years old, and her remarkable life ― including a career that continued for years after her initial diagnosis ― reveals just how productive and purposeful life can be with the neurological condition.
The way people experience Parkinson’s disease can be vastly different, and there is no one way the progressive disease typically unfolds. In some people, symptoms can be mild for many years, while others will be hit with severe disability and cognitive impairment early. About o...
