A traumatic brain injury (TBI) is defined as a blow or jolt to the head, or a penetrating head injury that disrupts the normal function of the brain. TBI can result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue. Symptoms of a TBI can be mild, moderate or severe, depending on the extent of damage to the brain. Mild cases (mild traumatic brain injury, or mTBI) may result in a brief change in mental state or consciousness, while severe cases may result in extended periods of unconsciousness, coma or even death. The 4th International Conference on Concussion in Sport held in Zurich, Switzerland in 2012 defined concussion, a subset of mTBI, as the following: Concussion is the historical term representing low velocity injuries that cause brain ‘shaking’ resulting in clinical symptoms and that are not necessarily related to a pathological injury. Concussion is a subset of TBI and will be the term used in this document. It was also noted that the term commotio cerebri is often used in European and other countries. Minor revisions were made to the definition of concussion, which is defined as follows: Concussion is a brain injury and is defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces. Several common features that incorporate clinical, pathologic and biomechanical injury constructs that may be utilised in defining the nature of a concussive head injury include: 1. Concussion may be caused either by a direct blow to the head, face, neck or elsewhere on the body with an "impulsive" force transmitted to the head. 2. Concussion typically results in the rapid onset of short-lived impairment of neurological function that resolves spontaneously. However, in some cases, symptoms and signs may evolve over a number of minutes to hours. 3. Concussion may result in neuropathological changes, but the acute clinical symptoms largely reflect a functional disturbance rather than a structural injury and, as such, no abnormality is seen on standard structural neuroimaging studies. 4. Concussion results in a graded set of clinical symptoms that may or may not involve loss of consciousness. Resolution of the clinical and cognitive symptoms typically follows a sequential course. However, it is important to note that in some cases symptoms may be prolonged. To view peer reviewed literature related to sports concussions, the Sports Concussion Library can be found here. Incidence The U.S. Consumer Product Safety Commission (CPSC) tracks product-related injuries through its National Electronic Injury Surveillance System (NEISS). According to CPSC data, there were an estimated 446,788 sports-related head injuries treated at U.S. hospital emergency rooms in 2009. This number represents an increase of nearly 95,000 sports-related injuries from the prior year. All of the 20 sports noted below posted increases in the number of injuries treated in 2009, except for trampolines, which posted 52 fewer injuries in 2009. Sports that exhibited substantial increases from 2008 to 2009 included water sports (11,239 to 28,716*), cycling (70,802 to 85,389), baseball and softball (26,964 to 38,394) and basketball (27,583 to 34,692). *Four categories were tabulated by the AANS in the current analysis that were not reflected in the 2008 injury data analysis, but together, these account for only 1,397 injuries. The actual incidence of head injuries may potentially be much higher for two primary reasons. 1). In the 2009 report, the CPSC excluded estimates for product categories that yielded 1,200 injuries or less, those that had very small sample counts and those that were limited to a small geographic area of the country; 2). Many less severe head injuries are treated at physician's offices or immediate care centers, or are self-treated. Included in these statistics are not only the sports/recreational activities, but the equipment and apparel used in these activities. For example, swimming-related injuries include the activity as well as diving boards, equipment, flotation devices, pools and water slides. The following 20 sports/recreational activities represent the categories contributing to the highest number of estimated head injuries treated in U.S. hospital emergency rooms in 2009.

Dehydration is a condition that occurs when the loss of body fluids, mostly water, exceeds the amount that is taken in. With dehydration, more water is moving out of our cells and bodies than what we take in through drinking. We lose water every day in the form of water vapor in the breath we exhale and in our excreted sweat, urine, and stool. Along with the water, small amounts of salts are also lost.

An atrioventricular septal defect (AVSD) is a heart defect in which there are holes between the chambers of the right and left sides of the heart, and the valves that control the flow of blood between these chambers may not be formed correctly

The long-standing answer has been that sneezing is a reflex. When irritants — such as germs, dust, pollen, animal dander, or pollutants, just to name just a few — infiltrate the nose lining, the brain sends out a signal to get rid of it. That triggers a deep breath, which gets held in the lungs.

Red blood cells, which form one of the major constituents of blood, are characterized by the absence of nuclei, hence they are unable to undergo cellular division or generate new erythrocytes from old ones. This eventually leads to cell disintegration, which typically occurs 4 months after the fully developed red blood cells have been in circulation within the bloodstream. During the degeneration of the red blood cells, some components of the hemoglobin are excreted from the body while other parts are conserved.

If it gets more severe and causes symptoms, your low hemoglobin count may indicate you have anemia. A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women.

Weight loss is the most effective nonpharmacologic measure to decrease blood pressure in overweight individuals. Weight loss with other nonpharmacologic measures can prevent or delay the onset of hypertension and reduce the overall risk of cardiovascular events in such patients. In some patients with established hypertension, lifestyle changes alone may control their blood pressure.

Parathyroid cancer is a rare disease in which malignant (cancer) cells form in the tissues of a parathyroid gland. The parathyroid glands are four pea-sized organs found in the neck near the thyroid gland. The parathyroid glands make parathyroid hormone (PTH or parathormone). PTH helps the body use and store calcium to keep the calcium in the blood at normal levels.

The heart's conductions system controls the generation and propagation of electric signals or action potentials causing the hearts muscles to contract and the heart to pump blood.

Angina, stroke and other vascular conditions are often caused by atherosclerosis ('arteriosclerosis') and treated by stenting, where doctors open up a blocked artery in the heart by inserting a sliver of metal into the artery to keep it open. However, there are allegations that far too many stents are being put in when medications and lifestyle changes could do the job just as well if not better.

Pericardiocentesis is the aspiration of fluid from the pericardial space that surrounds the heart. This procedure can be life saving in patients with cardiac tamponade, even when it complicates acute type A aortic dissection and when cardiothoracic surgery is not available. [1] Cardiac tamponade is a time sensitive, life-threatening condition that requires prompt diagnosis and management. Historically, the diagnosis of cardiac tamponade has been based on clinical findings. Claude Beck, a cardiovascular surgeon, described 2 triads of clinical findings that he found associated with acute and chronic cardiac tamponade. The first of these triads consisted of hypotension, an increased venous pressure, and a quiet heart. It has come to be recognized as Beck's triad, a collection of findings most commonly produced by acute intrapericardial hemorrhage. Subsequent studies have shown that these classic findings are observed in only a minority of patients with cardiac tamponade. [2] The detection of pericardial fluid has been facilitated by the development and continued improvement of echocardiography. [3] Cardiac ultrasound is now accepted as the criterion standard imaging modality for the assessment of pericardial effusions and the dynamic findings consistent with cardiac tamponade. With echocardiography, the location of the effusion can be identified, the size can be estimated (small, medium, or large), and the hemodynamic effects can be examined by assessing for abnormal septal motion, right atrial or right ventricular inversion, and decreased respiratory variation of the diameter of the inferior vena cava

http://stop-ear-ringing.info-pro.co ------ Ringing In Ears Dizziness, Can You Get Rid Of Tinnitus, Non Stop Ringing In Ear, Reduce Tinnitus Do you suddenly get up in the middle of the night hearing strange noises? Yes it can definitely be frightening, more so when you cannot find the source. Now consider for a moment that these sounds are coming from within you. Most people would be stunned to know that. Many of us do not even know that our internal organs can make sounds. Let us try to see whether you actually heard these noises or not, and if you did, where did they come from. Now before anything, let us get this straight - yes, you actually heard those noises. No, they are not a result of a creative mind that imagined things in slumber. But having said that, it is also true that there is indeed no source of the sounds you heard. So what is it? Confused? This is a classic case of tinnitus. What is tinnitus? What you experienced last night (or did you just get up from sleep and switch on the computer) is a classic case of tinnitus. This is a medical condition wherein a person hears all kinds of strange clicking, ringing, buzzing, whistling or hissing sounds within the ear. What's so worrisome about this condition for a lot of people is that, there's actually no physical source of these sounds. What makes it even worse is that, no one else seems to hear them. Frankly, these people cannot be really blamed. Naturally, if you cannot see where the sound is coming from, and if you keep hearing it, you are bound to get worried. In tinnitus, the sounds a person hears are actually perceptions. Since there's no actual source, they are often referred to as "phantom noises". Will it help you if you knew that about 8% of all people in the US suffer from tinnitus? Perhaps not, but at least now you know that you are not alone who hears these strange noises.

How To Increase Memory Power, How To Improve Memory Retention, How To Boost Memory Power.--- http://brain-revitalizer.info-pro.co ---- Brain Exercises, When people think of exercising it often involves physical exertion to strengthen muscles. The human brain is also an important "muscle" in the body and with the right brain training and brain exercises you can help keep your mind fit, alert and ready to handle the rigors of a typical working day. Often brain exercises come in the form of games that help train the brain improve memory, strategize and think in advance. Some common forms of brain exercise include chess, memory games and mathematical problem solving. Another way to exercise the brain is through brainwave entrainment. Isochronic tones are computer generated tones that are pulsed at specific frequencies to achieve desired effects such as productivity or relaxation. Although brainwave entrainment is not a new practice -- binaural beats have been used in brain training since the mid-1800's -- the use of computer generated isochronic tones has become more popular lately and are also proving to be more effective in helping people improve their memory and intelligence. Unfortunately when most people stop formal schooling, either by achieving a degree or choosing to drop out, the study habits and brain training that was part of their daily schedule also ends. The memorization and critical thinking that helped get us through school shouldn't have to stop just because a specific goal has been reached. In fact, if you don't keep up with brain exercises your mind will become lazy and won't function in the as sharply as it used to. The fact is, most people will never learn what it REALLY feels like to have their brains operating at a high capacity. They'll haphazardly try a few things, wonder why nothing is working, then go back to their mundane existence. But YOU can be different! You can use Genius Brain Power to empower your brain so that you come alive with more energy, learn quicker, think more creatively, focus on your work like never before and drastically reduce stress with amazingly deep states of relaxation and meditation. click here: http://brain-revitalizer.info-pro.co
