Main page Questions categories Philosophy and history Common philosophy Philosophy in education Philosophy and sociology Philosophy edu Students info Common articles Best philosophy topics Table of contents:. Concussion is diagnosed by determining what actually happened to the individual's brain function at the time of the injury. The examination of the athlete at the time of the injury or detailed accounts of the signs and symptoms at the time of the injury are much more valuable in formulating a diagnosis of concussion.
In the sport setting, eyewitness reports or videotape evidence of the injury are often available and helpful in the neurologic assessment of the athlete. Whereas psychological unconsciousness refers to a kose of unawareness or repressed ideas, 5 neurologic unconsciousness is paralytic coma. What do lose consciousness mean for a the neurologic unconscious state, responses to the external world are primitive or reflexic and may be absent altogether. After severe traumatic brain injury, emergence from a coma into vegetative state does not change the fact that the individual is still unconscious, even though the eyes may be open. Only in the somewhat higher level xonsciousness function known as the minimally conscious state do we see the beginning lise neurologic consciousness and higher-level behaviors indicating an awareness of the external world.
Early in the establishment of this scale and the associated Glasgow Outcome Scale GOS10 it became clear that deeper levels of coma as measured by lower scores on the GCS typically carry a worse prognosis and poorer outcome on the GOS in adults 11 and children. From decades of animal experiments and human experience with traumatic brain injury, we know that concussion commonly occurs without LOC. Unconsciousness lasting longer than 30 minutes is thought to indicate a more serious form of brain injury than concussion.
Pathophysiology of Loss of Consciousness
The mildest form was that of transient confusion without LOC or amnesia. The second grade included confusion plus PTA without unconsciousness. Within each of these grades, shearing strains on brain tissue produced lesions that were detected near the cortical surface in milder cases, while deeper lesions within the brain were associated with more severe biomechanical forces. What do lose consciousness mean for a forces that affect head movement cause mechanical stress within the brain tissue, producing a sudden electric discharge or depolarization of nerve cells throughout the brain.
This electric depolarization leads to an outpouring of neurotransmitters in the brain, and a cascade of neurochemical changes results in excitatory and damaging effects on the nerve cells. The subsequent metabolic rearrangement can be measured by sophisticated functional neuroimaging techniques such as positron emission tomography PET scanning. High-powered electron microscopes have been used to analyze changes in brain tissue after mild traumatic forces have been applied. Neurochemical 28 and structural changes, 2930 followed by the delayed effects of diffuse axonal injury, 27 are known to occur with mild traumatic brain injury.
Even so, it is not clear whether the mildest form of concussion, such as that producing transient confusion without amnesia, leads to these anatomical changes. Studies of cerebral glucose metabolism in human traumatic brain injury have failed to show a relationship between LOC and metabolic perturbations how many cheek italysi follow the injury. Glucose metabolism of patients who had sustained concussion on what date should kiss girl are fully alert at the time of PET scanning is not significantly different than those who are comatose at the time of the testing. Neuropsychological testing is our most sensitive measure of cognitive dysfunction after concussion, and it is the most useful method of determining readiness to return what do lose consciousness mean for a play.
Studies using neuropsychological tests after concussion have failed to show any difference between those who lost consciousness and those who did not. The most powerful way of using these instruments is to obtain preinjury testing on each athlete, so that postinjury scores can be compared against individual baseline performance. Some amateur sports teams are using this technique, and such tests have become standard parts of concussion evaluation protocols for some college football programs 34 and the National Hockey League.
What causes loss of consciousness?
I have been involved in coordinating the neuropsychological what do lose consciousness mean for a program for the Chicago Bears for the last 7 years. However, if cognitive functions are not evaluated within minutes of the injury, the distinction between grades of concussion is lost. Sideline mental status testing can be valid and useful in documenting the effects of concussion. We recently reported that neurocognitive deficits can be detected immediately after even mild concussions in football players with the Standardized Assessment of Concussion SAC. Only the mildest form of concussion was associated with rapid recovery of cognitive functions by retesting at 15 minutes after the injury. The group with PTA improved somewhat but did not regain the baseline level of performance. The LOC group demonstrated virtually no improvement in cognitive functions by 15 minutes postinjury. The findings of https://agshowsnsw.org.au/blog/does-usps-deliver-on-sunday/lumity-kiss-on-cheek.php study are most consistent with the grading scale published by the Colorado Medical Society.
Any athlete rendered unconscious grade 3 for even a few seconds must not be allowed to return to that practice or game and must undergo neurologic examination by a physician. In fact, only those without amnesia whose symptoms clear within 15 minutes are allowed to return to play that day. LOC lasting several minutes should be viewed as a potential neurosurgical emergency requiring urgent medical evaluation. A brief LOC is followed by 1 week off. Longer periods of LOC extend the time of recovery by an additional week or more. Two grade 3 concussions in the same season result in 1 month off. Other contributory factors, such as persistent headache, head pain from associated soft tissue injury, neck pain, and sleep disturbance adversely affect mental functions and can prolong recovery time.
The athlete's physician may determine that a longer recovery time is required. More than one member of a panel of sports medicine what do lose consciousness mean for a 31 reported routinely returning players to the same practice or game in which they had been rendered unconscious. Such a practice is unsupported by neuroscience or expert consensus and puts the athlete in danger of permanent and possibly catastrophic neurologic harm. It is rewarding to have the opportunity to present this information to the readership of the Journal of Athletic Training because the athletic trainer is the health care professional most likely to witness a concussion during a sport event and is most often in a position to initiate the evaluation and management of the injured player.
A growing body of scientific knowledge supports the notion that concussion should be considered a serious medical condition that can have a long-lasting and even catastrophic outcome if misunderstood and mismanaged.
Wellness A-Z
I have reviewed the evidence regarding the role of LOC in the diagnosis and management of sport concussion. The evidence generally supports the contention that concussion with LOC represents a worse form of brain injury than concussion without LOC but that rates what do lose consciousness mean for a loe vary from individual to individual. Detailed neurologic evaluation, neuroimaging, neuropsychological assessment, and honest reporting of symptoms by the athlete each have very important roles in the safe management of concussion. All return-to-play guidelines published in recent times emphasize the need for monitoring an athlete with mental status testing of some kind and insisting that he or she be symptom free for some prescribed period of time before returning to activity. Neuropsychological evaluation of the athlete who had been rendered unconscious should be done whenever possible before clearance to return llse play. Again, these guidelines are based on the consensus click specialists selected for their expertise in the diagnosis and management of sport concussion.
Recent evidence in medical science seems to support the observation that we have been underestimating the amount of time it takes to recover from concussion. The careful clinician errs on the side of caution in making return-to-play decisions after concussion in sports. National Center for Biotechnology InformationU. Journal List J Athl Train v.
