Today in our society we see more attention drawn to concussions and the aftermath of the injury. Most recently Hollywood put out a new movie, Concussion, starring Will Smith. The movie follows the story of a doctor who is researching the effects of repeated concussions in football players. Now, not all of us are out on the field wearing shoulder pads and helmets.

The reality of the situation is that concussions are not only common in contact sports. According to a NPR poll conducted, almost 1 in 4 Americans claim they have had a concussion at one point in time. Luckily over 75% of these Americans sought medical attention.

Smaller hits to the head can be categorized as sub-concussive hits. These smaller hits build up over time; what starts out as a small bump every now and then, overtime, may result in a full-blown concussion. According to Dr. Harry Kerasidis, it all depends on the health of your brain.

To clarify, every time you hit your head does not mean you will be diagnosed as concussed. After hitting your head in small doses overtime, one more minuscule hit to the head may result in a concussion due to the fact that you had hit your head in smaller doses overtime.

Concussions have the tendency to be sneaky and have various symptoms. What you may think is just a relentless headache, may actually be a concussion. Other symptoms include a loss of consciousness, nausea and/or vomiting, sensitivity to light and sound, cloudy thinking and problems with memory. Unfortunately, it is common for these symptoms to go unnoticed for minutes, hours, and sometimes even days. These delayed symptoms push back the aid that medical attention can provide.

Before diving into treatment of concussions, it is important to point out what happens to the brain when a concussion occurs. The brain floats in cerebral spinal fluid inside the skull. The fluid acts as a buffer between the organ and the skull itself.

A concussion is when the brain rapidly moves within the skull and the cerebral spinal fluid cannot protect the brain from hitting the inner skull. When a blow to the head occurs, the brain accelerates and quickly hits one side of the skull. In the deceleration process, the brain hits the opposite side of the skull before settling back into place.

Another potential reaction of the brain to a traumatic blow is known as a rotational concussion. During this, the brain moves from one side to the other in a rapid movement. More often than not this results in shearing and straining of brain tissues. Either situation can cause long term neurological issues.

Treatment of concussions typically follows one major guideline; the injured person needs to rest. Simply laying down on the couch will not suffice. It is advised that the concussed person physically and mentally rest to allow the brain to fully rest. Avoiding stimulating situations such as classrooms, reading, and watching television is advised. Physical activity is frowned upon. Easing back into everyday activities is advised. Going back to life all at once can cause overstimulation, and symptoms may reappear.

The progression of recovery from a concussion depends on the severity of the injury itself. When not properly treated long term effect may ensue in the individual, if all seems fine, the next head injury they sustain may be that much worse. It is best to seek and obtain medical attention regardless of the severity of the concussion.

The most common victims of concussions are young, active individuals. Most of these young folks are concussed due to participation in a contact sport. As previously stated, Hollywood produced the film Concussion, stemming from football players.

Today, concussions are gaining notoriety because many professional athletes are speaking out on the matter. Is the attention surrounding concussions too much? In the same poll conducted by NPR, 11 percent of people said the attention concussions receive is exaggerated, 80 percent thought it was appropriate, and the remaining 7 percent simply did know.

Scientists Discover A New Method To Fight Alzheimer’s, Dementia

Worldwide, about seven percent of people over 65 suffer from Alzheimer's or some form of dementia, a percentage that rises to 40 percent above the age of 85.

Eliminating dead-but-toxic cells occurring naturally in the brains of mice designed to mimic Alzheimer’s slowed neuron damage and memory loss associated with the disease, according to a study published Wednesday that could open a new front in the fight against dementia.The accumulation in the body of “zombie cells” that can no longer divide but still cause harm to other healthy cells, a process called senescence, is common to all mammals.

Scientists have long known that these dead-beat cells gather in regions of the brain linked to old age diseases ranging from osteoarthritis and atherosclerosis to Parkinson’s and dementia.

Prior research had also shown that the elimination of senescent cells in ageing mice extended their healthy lifespan.

But the new results, published in Nature, are the first to demonstrate a cause-and-effect link with a specific disease, Alzheimer’s, the scientists said.

But any treatments that might emerge from the research are many years down the road, they cautioned.

In experiments, a team led by Tyler Bussian of the Mayo Clinic in Rochester, Minnesota used mice genetically modified to produce the destructive, cobweb-like tangles of tau protein that form in the neurons of Alzheimer’s patients.

The mice were also programmed to allow for the elimination of “zombie” cells in the same region.

“When senescent cells were removed, we found that the diseased animals retained the ability to form memories, and eliminated signs of inflammation,” said senior author Darren Baker, also from the Mayo Clinic.

The mice likewise failed to develop Alzheimer’s signature protein “tangles”, and retained normal brain mass.

Keeping zombies at bay

A closer look revealed that the “zombies” belonged to a class of cells in the brain and spinal cord, called glia, that provide crucial support and insulation to neurons.

“Preventing the build-up of senescent glia can block the cognitive decline and neuro-degeneration normally experienced by these mice,” Jay Penney and Li-Huei Tsai, both from MIT, wrote in a comment, also in Nature.

Bussian and his team duplicated the results with pharmaceuticals, suggesting that drugs could one day slow or block the emergence of Alzheimer’s by keeping these zombie cells at bay.

“There hasn’t been a new dementia drug in 15 years, so it’s exciting to see the results of this promising study in mice,” said James Pickett, head of research at Alzheimer’s Society in London.

For Lawrence Rajendran, deputy director of the Dementia Research Institute at King’s College London, the findings “open up new vistas for both diagnosis and therapy for neurodegenerative diseases, including Alzheimer’s.”

Up to now, dementia research has been mostly focused on the diseased neurons rather than their neighboring cells.

“It is increasingly becoming clear that other brains cells play a defining role,” Rajendran added.

Several barriers remain before the breakthrough can be translated into a “safe, effective treatment in people,” Pickett and other said.

The elderly often have lots of harmless brain cells that look like the dangerous senescent cells a drug would target, so the molecule would have to be good at telling the two apart.
