Why do some people seem to suffer no consequences from a concussion while others have symptoms as severe as personality change? The new technique analyzes data from brain imaging studies, according to the study published in the journal Brain Imaging and Behavior today.
Earlier studies identified differences in patients with concussions and those without, but the new technique takes the additional step of parsing out the differences in patients who have concussions. The technology driving the analysis is called diffusion tensor imaging, a new form of MRI that the researchers also used recently to show the cumulative effects of frequent headers in soccer players. To analyze the data, the researchers developed a new software tool (called Enhanced Z-score Microstructural Assessment Pathology).
Through the use of OCT, visual field, and retinal photography, our doctors are able to monitor your eye health to detect conditions before they affect your vision. There are multiple causes of dry eye, and the use of artificial tears alone is only adequate for a small percentage of people.
Ocular Disease Management: The doctors at Artisan Optics diagnose and manage a wide range of eye diseases as well as the eye involvement of systemic diseases such as diabetes or hypertension. Acquired Brain Injury: Whether due to trauma, stroke, or neurological disease, brain injuries have a known effect on the visual system. Athlete Vision Assessment: During competition athletes are required to use their eyes at a much higher level than in day-to-day life.
Vision Therapy: Vision therapy is a program designed to treat binocular dysfunction and visual perceptual deficits. When someone is involved in a personal injury accident and suffers a concussion, often they will exhibit negative and persistent symptoms. Post-concussion syndrome is complex and not always are the symptoms the same from one personal injury victim to another.
For instance, headaches, dizziness, sensitivity to light and even nausea can be associated with PCS. It is important to remember that many if not all of these symptoms may not show up for weeks or even months after someone sustains a concussion or brain injury. What is also important is that if you have sustained a concussion, regardless whether any of the above discussed symptoms are present, that you get the medical care and attention you need.

Losing consciousness right after a bump on the head is a warning indication of a possible concussion even if it only lasts for a few seconds. The typical symptoms to watch out for include a dazed expression after the injury, vomiting, headache and prolonged crying. Other possible symptoms include blurred vision or headache while seizures can also occur but uncommon. Diminished level of energy, irritability or not playing as usual might indicate a possible concussion. The symptoms might not be evident in the initial few days after the injury, but becomes noticeable over time.
There is also an increase in temper tantrums or becoming impatient as well as crying more than usual.
A concussion is a mild form of closed head trauma, so an injury that results in a skull fracture or subdural hematoma (bleeding between the brain and skull) can't be accurately described as a concussion. In addition to lasting cognitive and emotional effects, concussion victims typically exhibit several immediate signs and symptoms that can help you diagnose such an injury.

A few common characteristics of concussions include nausea, loss of coordination or balance, confusion, delayed reaction time, slurred speech and memory loss. People commonly keep small alterations of consciousness to themselves, which can contribute to the underreporting of concussions. So far, we've mostly covered the physical effects of concussion, but concussions don't stop there -- they can also affect a person's ability to think, which can be especially debilitating. Concussions, while fairly hard to detect compared to other sports injuries, have direct protocol for diagnosis. A new type of brain scan helps explain why, and could help doctors and patients determine the likely outcomes of a concussion. Concussion victims have unique spatial patterns of brain abnormalities that change over time, researchers found, which could help predict which head injuries are likely to have long-lasting neurological consequences.
The researchers used it on 34 patients within two weeks of injury and again three and six months later.
They used it to observe whether brain tissue had maintained its integrity at a microstructural level. With early detection, we are able to initiate treatment sooner and preserve your vision and eye health. Our doctors will evaluate both the severity and cause of your dry eye before designing a treatment protocol that addresses the underlying cause of your symptoms. Binocular vision, or the ability to use the two eyes together in a coordinated manner, is just as important for vision functioning.
When this happens, the symptoms are signs of a disorder known as post-concussion syndrome (PCS) also referred to as post concussive syndrome.
At times the symptoms can last for weeks or even months and longer after the initial event or accident that caused the injury or concussion. Too many head injuries go unreported and untreated due to the belief that a concussion or mild traumatic brain injury only requires rest and no real medical care – nothing could be farther from the truth. Toddlers are quite inquisitive of their surroundings that they often endure falls and tumbles that result to undesirable head bumps. The child will also complain of a belly that “does not feel right” which might indicate nausea.
Changes in the sleeping pattern of the child such as sleeping more than usual or avoids taking naps are other signs to watch out for. There might be changes in the eating habits, lack of interest in favorite activities or toys and unusual sadness or grumpiness.
It is vital to note that head injuries should not be taken lightly and monitor for any symptoms of a possible concussion.
Otherwise, call a doctor right away to report anything more than a minor bump on the head and discuss if the child needs assessment and what to watch out for if the doctor advises monitoring at home.
In other words, if bleeding is present in a computer topographic (CT) scan, then another type of brain injury is present [source: Cuhna]. Although it isn't necessarily required for diagnosis, loss of consciousness is among the most common signs that a concussion has occurred. However, there are a few outward signs that a person typically displays after experiencing one. Examples of the kind of vision problems that concussions might cause include photophobia -- a strong aversion to bright lights -- as well as seeing stars or having double vision.
A victim may experience phonophobia -- an aversion to loud noises -- and ringing of the ears.

A concussion is a type of an athletic injury defined as “a type of traumatic brain injury caused by a bump, blow, or jolt to the head that disrupts the way the cells in the brain normally work” (Sarmiento 2010). DTI detects subtle damage to the brain by measuring the direction of diffusion of water in white matter. Diagnostic imaging is crucial when monitoring conditions such as diabetes within the eye, glaucoma, or macular degeneration. This approach allows us to improve your tear functioning rather than masking the problem with drops. Additionally, individuals with visual perceptual challenges, working memory and processing speed deficits, as well as those with acquired brain injury can be helped with vision therapy. Cognitive problems like difficulty concentrating, irritability, and memory issues are also associated with PCS.
Concussions are also considered as mild traumatic brain injuries which causes a disruption in the normal brain functioning. Slurred speech, unusual clumsiness, frequent falls and lack of coordination can also develop. Most mild brain injuries can't be detected by magnetic resonance imaging (MRI) or a computer topographic CT scan [sources: CINN, Yamamoto]. However, some alteration of consciousness must take place in order to accurately classify an injury as a concussion [Source: Lew].
Among these symptoms are vacant facial expressions, delayed reaction times, loss of focus or inability to pay attention. Concussions can also be psychologically disruptive, and victims may exhibit irritability, anxiety and depression. During this injury, the brain collides with the inner wall of the skull, causing bruising to in the affected brain cells. Each concussion patient also had a unique spatial pattern that evolved over the study period.
Thanks to recent research in the area of neuroplasticity, we know that people of all ages can benefit from vision therapy. And the symptoms can also be psychological in nature; depression, anxiety, fatigue, and judgement issues can be due to PCS. Even so, such procedures are often used to detect possible severe brain damage in patients who have experienced head trauma. Therefore, even if a victim adamantly denies having experienced a subtle change in consciousness, there are certain telltale signs that allow an experienced observer to detect when a concussion has occurred [source: Lew].
Symptoms of a concussion include headache, nausea, vomiting, balance problems, dizziness, etc. It is vital that you are familiar with the signs and symptoms of a concussion since toddlers could not put into words any symptoms that they might be experiencing. Later, we'll go into detail about the various tests you can administer someone that you suspect may have recently had a concussion. Post-traumatic or retrograde amnesia is not uncommon, and the centers of the brain that control planning, ability to follow instructions, verbal fluency and brain-eye coordination may all become discombobulated by concussion [source: Lew]. Because these symptoms do not include any noticeable outward changes in health, such as a swollen ankle, the diagnosis of a concussion is often missed.
