3. Ronald Savage, an expert in traumatic brain injury Traumatic brain injury (TBI), traumatic injuries to the brain, also called intracranial injury, or simply head injury, occurs when a sudden trauma causes brain damage. TBI can result from a closed head injury or a penetrating head injury and is one of two subsets of acquired brain (TBI TBI 1. Thyroxine-binding index 2. Total body irradiation ), just as many children recorded in this databank sustained traumatic brain injury as fractures.
How many children suffer head trauma? A lot! Published estimates place the incidence of significant head trauma between 200 and 300 per 100,000 children and adolescents, or between 54,000 and 81,000 per year in the US. That number is probably even higher since symptoms of brain injury are similar to other categories in special education that are more familiar to school personnel. Many children with TBI are incorrectly classified by registries or databanks in special education as being learning disabled, developmentally disabled, emotionally disturbed or as having attention deficit hyperactivity disorder attention deficit hyperactivity disorder (ADHD), formerly called hyperkinesis or minimal brain dysfunction, a chronic, neurologically based syndrome characterized by any or all of three types of behavior: hyperactivity, distractibility, and impulsivity. .
The term "traumatic brain injury" refers to a specific type of disability that occurs after birth (usually, but not always, due to accident or abuse); in fact, it is sometimes referred to as "acquired brain injury A neurological condition, Acquired Brain Injury (ABI) is damage to the brain acquired after birth. It usually affects cognitive, physical, emotional, social or independent functioning and can result from traumatic brain injury (i.e. accidents, falls, assaults, etc. ," as opposed to something with a genetic or "unknown" cause.
The consequences of TBI depend heavily on the type of injury, on the part of the brain where the injury occurred and on the age of the child. At one time it was assumed that children would recover better and more quickly if the accident occurred in early childhood, in the belief that brain plasticity would aid in recovery. Now it is recognized that younger children, ages birth to five years, have a more difficult time recovering because their brains are injured during a period of rapid brain growth and maturation. Indeed, since older adolescents and young adults have simply had a longer time living and coping with daily events, they have more practical knowledge and experience to help compensate for an injury to the brain. This new knowledge makes the fact that the majority of brain injuries occur in children under the age of 10 even more cause for concern. Incidentally, twice as many boys as girls sustain a traumatic brain injury.
What are some of the common causes of TBI? The national registry on brain injury, mentioned above, reports that most pediatric TBI injuries result from motor vehicle collisions (27.1%) and falls (26.5%), like the one Jack, and so many others in classic nursery rhymes nursery rhymes, verses, generally brief and usually anonymous, for children. The best-known examples are in English and date mostly from the 17th cent. A popular type of rhyme is used in "counting-out" games, e.g., "Eenie, meenie, minie, mo. , took.

Do certain activities place a child at risk? Despite their propensity to recover skills more quickly, older children and youth are more likely to engage in sports, a widespread risk factor for head injury. In the old days, coaches and even parents were quick to dismiss head injuries as "bell ringers" or just as part of the game. Today we are well aware that playing sports can carry a risk of concussion, a mild form of brain injury. Football is not solely to blame, although it is certainly the main culprit. High risk is also associated with ice hockey ice hockey: see hockey, ice.

Their report draws on data from the Centers for Disease Control and Prevention Centers for Disease Control and Prevention (CDC), agency of the U.S. Public Health Service since 1973, with headquarters in Atlanta; it was established in 1946 as the Communicable Disease Center. estimating 300,000 sports-related concussions in the US each year.
Kelly and Savage provide explicit guidelines for determining whether to return an athlete, or a child, to the game. For example, according to their guidelines, after a grade 1 or mild concussion, an athlete can be returned to play only if he or she is symptom-flee at rest, or symptom-free with exertion within 15 minutes of the injury. In a grade 2 or moderate concussion, the individual should refrain from sports for at least a week. In a grade 3 concussion, which is the most severe, there is typically a loss of consciousness; thus, return to play should occur after a minimum one-month recovery. However, there are exceptions and caveats even to these guidelines, allowing more or less rest and recommendations for follow-up examination.
In an extensive review of neuropsychology's contribution to understanding brain injury during sports, Ruben Echemendia and Laura Julian propose that neuropsychological tests may be more useful than traditional neuroimaging techniques because they can detect subtle losses in an athlete's attention and concentration. Echemendia and Julian also note that these traditional neuroimaging techniques, such as computerized tomography (CT) and magnetic resonance imaging magnetic resonance imaging (MRI), noninvasive diagnostic technique that uses nuclear magnetic resonance to produce cross-sectional images of organs and other internal body structures.

Most parents (and educators and coaches for that matter) are not aware of post-concussion syndrome Post-Concussion Syndrome Definition
Post-concussion syndrome (PCS) is a common but controversial disorder that presents with variety of symptoms including—but not limited to—headache, dizziness, fatigue, and personality changes. , which refers to repeated concussions over an extended period of time. Obviously, the more frequent the concussions, the greater the likelihood that there will be neurological, cognitive and/or behavioral deficits in the child or young adult.
It is important that parents, teachers and other professionals who work with the child monitor his or her cognitive, behavioral and physical changes for six to eight weeks following an injury. Fortunately, with a first injury, no permanent negative effect is likely, and full recovery of the injured child is expected. But, because a child active in sports can have four or more different coaches during high school, parents must be responsible for being aware of their child's injury history and making sure each new coach is also kept apprised.

Researcher Jenny Sherrard and her colleagues in Australia recently published results of a large-scale study on injury risk in about 500 young people ages 4 to 18 years with an intellectual disability. The investigators used data collected across two time periods five years apart, which allowed them to calculate risk factors over time. Parents answered questionnaires about the child's development and behavior and about family functioning and economic status. The authors identified three risk factors highly associated with injury: having epilepsy, which increases the likelihood of falls; having clinically significant levels of behavioral or emotional problems; and having an overly sociable temperament (e.g., attempting more risky activities without a full understanding of the consequences). Clearly, acquiring a brain injury in addition to another disability constitutes a double-whammy for both the child affected and his parents.

Ground rent deeds and leases frequently contain a clause authorizing the landlord to reenter on the non-payment of rent, or the breach of some covenant, when the to school are all paramount in determining the long-range impact of TBI. Several recent studies by a team of researchers at Case Western Reserve University and Ohio State University Ohio State University, main campus at Columbus; land-grant and state supported; coeducational; chartered 1870, opened 1873 as Ohio Agricultural and Mechanical College, renamed 1878. There are also campuses at Lima, Mansfield, Marion, and Newark. (led by H. Gerry Taylor, Keith O. Yeates and colleagues) report on both short- and long-term outcomes for children with TBI. In all cases, children who have moderate or severe TBI and were from socially advantaged homes (whereby parents have higher incomes, more resources and, potentially, fewer family stressors related to the parents' health or work) had lower risk of depression and lower rates of other new psychiatric disorders following injury. These studies determined that "environmental advantages" are critical for predicting positive outcomes in children after injury.
Furthermore, siblings seem to adjust well to having a brother or sister with a serious TBI, as reported in a study by Mary McMahon and her colleagues. These researchers hypothesized that siblings of affected children might have more "acting out" or behavior problems, as well as more "acting in" problems, such as depression or poor self-concept. However, their studies found that there were no significant differences in these areas when, 3 to 18 months after the original injury, the siblings were compared to their classmates Classmates can refer to either:

Adj. 1. to know that rapidly developing technology can better detect brain abnormalities and pinpoint areas of functioning--such as social skills, the management of emotions, mathematical processing and reading--that might be negatively affected. At a more practical level, rehabilitation and education efforts have also advanced, and there is growing awareness of TBI among public school personnel. Promising interventions used successfully with children with learning or cognitive disabilities also seem to work with TBI. For example, "self-monitoring" techniques taught to children with TBI have proven effective for increasing on-task behavior, task accuracy and even improving social skills. If Humpty Dumpty had lived today, it is likely that the neurosurgeons, psychologists, rehabilitation specialists and special education teachers would be pretty successful in putting him back together again.
