Plain x-rays of the skull are recommended by some as a way to evaluate patients with only mild neurological dysfunction. However, most centers in the U.
Because it is difficult to transport an acutely-injured patient from the emergency room to a MRI scanner, the use of MRI is impractical. However, once a patient is stabilized, MRI may demonstrate the existence of lesions that were not detected on the CT scan. This information is generally more useful for determining prognosis than for influencing treatment. Many patients with moderate or severe head injuries head directly from the emergency room to the operating room.
In many cases, surgery is performed to remove a large hematoma or contusion that is significantly compressing the brain or raising the pressure within the skull. After surgery, these patients are under observation in the intensive care unit ICU.
Other head-injured patients may not head to the operating room immediately, instead are taken from the emergency room to the ICU. Since contusions or hematomas may enlarge over the first hours or days after head injury, immediate surgery is not recommended on these patients until several days after their injury.
Delayed hematomas may be discovered when a patient's neurological exam worsens or when their ICP increases. On other occasions, a routine follow-up CT scanto determine whether a small lesion has changed in size indicates that the hematoma or contusion has enlarged significantly.
In these cases, the safest approach is to remove the lesion before it enlarges and causes neurological damage. During surgery, the hair over the affected part of the head is usually shaved. After the scalp incision, the removed bone is extracted in a single piece or flap, then replaced after surgery unless contaminated.
The dura mater is carefully cut to reveal the underlying brain. After any hematoma or contusion is removed, the neurosurgeon ensures the area is not bleeding.
He or she then closes the dura, replaces the bone and closes the scalp. If the brain is very swollen, some neurosurgeons may decide not to replace the bone until the swelling decreases, which may take up to several weeks.
The neurosurgeon may elect to place an ICP monitor or other types of monitors if these were not already in place. The patient is returned to the ICU for observation and additional care. At present, medication administered to prevent nerve damage or promote nerve healing after TBI not available. The primary goal in the ICU is to prevent any secondary injury to the brain. The "primary insult" refers to the initial trauma to the brain, whereas the "secondary insult" is any subsequent development that may contribute to neurological injury.
For example, an injured brain is especially sensitive and vulnerable to decreases in blood pressure otherwise well tolerated. One way to avoid secondary insults is to attempt normal or slightly elevated blood pressure levels. Likewise, increases in ICP, decreases in blood oxygenation, increases in body temperature, increases in blood glucose and many other disturbances can potentially worsen neurological damage. The major role of ICU management is the prevention of secondary insults in head-injured patients.
Various monitoring devices may assist health care personnel in caring for the patient. Placement of an ICP monitor into the brain can help detect excessive swelling.
One commonly used type of ICP monitor is a ventriculostomy, a narrow, flexible, hollow catheter that is passed into the ventricles, or fluid spaces in the center of the brain, to monitor ICP and drain CSF if ICP increases. The Brain Injury Association of America reports that brain injuries are the leading cause of death and disability in children and teenagers.
Additional signs of TBI in children are:. Most people who sustain a concussion completely recover within a couple of weeks of their injury. A few, however, along with those who sustained a moderate or severe TBI, have to deal with a host of persistent symptoms indefinitely.
Of course, they vary in intensity from person to person. Some of them tend to appear immediately after an injury. Others sometimes develop later. Some symptoms might seem to come and go, triggered by certain environments or situations. The chart below contains some of the most common long-term effects of TBI and when they frequently appear following a TBI.
As you can see from these lists, TBI can cause physical symptoms and affect the nervous system in addition to cognitive function. There are a couple of symptoms on this list that appear to vary depending on whether a patient had an mTBI or a severe TBI. People who suffered a concussion often remember the injury, or the memory eventually returns. A range of mental health and emotional issues can affect those who have suffered a TBI. Anxiety and depression are common. Personality mood changes , mood swings, and difficulty controlling impulses can also be an issue.
The challenges associated with life after a TBI and the emotional and personality changes that sometimes go along with it can also contribute to relationship difficulties. The injury can cause roles in a partnership to change.
A study by Virginia Commonwealth University investigated divorce rates following TBI and identified some important potential factors in separation and divorce. Some of the findings were not definitive; however, they did find that older people and those who had been married longer before the injury were less likely to divorce.
Another condition related to TBI worth mentioning is that sometimes an event that causes a TBI can also cause post-traumatic stress disorder. It is possible to have both and need treatment for both.
Lingering brain injury symptoms can range from frustrating to incapacitating. To learn more about how we can help you recover, book a free consultation. What causes some people to experience traumatic brain injury effects years after their injury? The key to that answer is understanding a process called neurovascular coupling and what happens when it malfunctions. Neurovascular coupling is the communication system between brain cells neurons and blood vessels. Neurons are the cells that carry messages back and forth between the brain and the body.
Glucose and oxygen are the fuel the brain needs to operate, and they are carried through the blood vessels. When the body has a demand, the brain anticipates the need for the right amount of fuel at the right time to fulfill that demand. When the demand in an area increases, the brain calls for more fuel.
This causes the brain to direct more glucose and oxygen to that area. For example, as soon as you think you need to read something, your brain anticipates how much fuel it needs and where it needs it to allow you to complete this task of reading — even before you begin to read! The brain needs to be ready at the precise moment that you begin to read.
It sets this all up through neurovascular coupling. An injury to the brain sometimes damages neuronal connections. Inflammation and swelling in response to the injury can diminish the amount of blood traveling to or through those injured areas. This disrupts the established neurovascular coupling pathways without resulting in cell death. As a result, these brain regions are hypoactive underperforming. Sometimes, however, an area of the brain is overactive: It gets too much energy.
That is a hyperactive area of the brain. In either case, TBI symptoms are the consequence of this dysfunction. When people recover from a brain injury, those pathways will either return to normal or continue malfunctioning.
If they fail to revert to healthier signaling after the trauma of the acute injury subsides, the result is long-term dysfunction of neurovascular coupling and thus long-term symptoms of TBI. The good news is that dysfunctional neurovascular coupling is detectable and treatable with the right diagnostic tools and therapy. Of the approximately 2. A concussion is generally diagnosed by observing the injured person for typical symptoms and by evaluating their reactions and responses. In sports, a variety of protocols have been implemented to try to detect a possible concussion in athletes.
Some athletes are required to take a pre-season baseline test so that before- and after-injury health information can be compared if necessary. Some use the Balance Error Scoring System because balance problems after an injury are indicative of a concussion.
Others use standard guidelines such as the Concussion Recognition Tool 5 or one of the Sport Concussion Assessment Tools , which vary according to the age of the athlete. If symptoms or circumstances indicate the possibility of a moderate to severe TBI, a trip to the emergency room is necessary to look for life threatening bleeding, swelling, and fractures. Neuropsychological tests to gauge brain functioning are often used in conjunction with imaging in people who have suffered mild TBI.
Such tests involve performing specific cognitive tasks that help assess memory, concentration, information processing, executive functioning, reaction time, and problem solving. A total score of indicates a severe head injury; indicates moderate injury; and is classified as mild injury.
Baseline testing should begin as soon as a child begins a competitive sport. Brain function tests can be repeated at regular intervals every 1 to 2 years and also after a suspected concussion. The results may help health care providers identify any effects from an injury and allow them to make more informed decisions about whether a person is ready to return to their normal activities. Many factors, including the size, severity, and location of the brain injury, influence how a TBI is treated and how quickly a person might recover.
Although brain injury often occurs at the moment of head impact, much of the damage related to severe TBI develops from secondary injuries which happen days or weeks after the initial trauma. For this reason, people who receive immediate medical attention at a certified trauma center tend to have the best health outcomes. Some people with mild TBI such as concussion may not require treatment other than rest and over-the-counter pain relievers.
Children and teens who have a sports-related concussion should stop playing immediately and return to play only after being approved by a concussion injury specialist.
Preventing future concussions is critical. While most people recover fully from a first concussion within a few weeks, the rate of recovery from a second or third concussion is generally slower.
Even after symptoms resolve entirely, people should return to their daily activities gradually once they are given permission by a doctor. There is no clear timeline for a safe return to normal activities although there are guidelines such as those from the American Academy of Neurology and the American Medical Society for Sports Medicine to help determine when athletes can return to practice or competition. Further research is needed to better understand the effects of mild TBI on the brain and to determine when it is safe to resume normal activities.
People with a mild TBI should:Make an appointment for a follow-up visit with their healthcare provider to confirm the progress of their recovery. Surgery may be needed to for emergency medical care and to treat secondary damage, including:.
People with TBIs may need nutritional supplements to minimize the effects that vitamin, mineral, and other dietary deficiencies may cause over time. Some individuals may even require tube feeding to maintain the proper balance of nutrients. After the acute care period of in-hospital treatment, people with severe TBI are often transferred to a rehabilitation center where a multidisciplinary team of health care providers help with recovery. The rehabilitation team includes neurologists, nurses, psychologists, nutritionists, as well as physical, occupational, vocational, speech, and respiratory therapists.
Some therapy is provided through outpatient services. Cognitive rehabilitation therapy CRT is a strategy aimed at helping individuals regain their normal brain function through an individualized training program. Using this strategy, people may also learn compensatory strategies for coping with persistent deficiencies involving memory, problem solving, and the thinking skills to get things done. CRT programs tend to be highly individualized and their success varies. A Institute of Medicine report concluded that cognitive rehabilitation interventions need to be developed and assessed more thoroughly.
Genetics may play a role in how quickly and completely a person recovers from a TBI. They may have a drop in blood pressure, fainting, and other related issues. They often also experience many other symptoms related to dysautonomia:. Neurocardiogenic syncope is a loss of consciousness or near-fainting and dizziness caused by a sudden drop in blood flow to the brain.
Each episode is often accompanied by other symptoms such as nausea, fatigue, brain fog, and general discomfort. In other words, to get to the heart of the issue, it takes going beyond the diagnosis of POTS or syncope.
Treatment outcomes are better when we understand the underlying issue causing these symptoms. Not all cases of POTS or syncope are concussion related. We can also give patients strategies to improve and manage their dysautonomic symptoms over time.
Dysautonomia patients often see doctors who will treat one or two symptoms but not others. If they were aware of their head injury, their concussion management plan is simple: Stay at home and rest until the symptoms improve.
Each symptom, if treated at all, is treated as an isolated issue rather than as a related cluster of symptoms. At Cognitive FX, we use a multidisciplinary approach. If you fix one system but the others are still out of balance, it could pull the others more out of balance. We know that post-concussion patients suffer from poor neurovascular coupling the connection between neurons and the blood vessels that supply them with nutrients. Each patient receives an fNCI brain scan that we use to pinpoint the specific areas of the brain experiencing neurovascular decoupling.
The exact regimen is tailored to each person based on their medical history, symptoms, physical evaluations, and biomarkers identified in the fNCI scan. One aspect of the treatment program which engages the autonomic nervous system is a cycle of exercise, cognitive effort, and rest.
You will prepare your brain and nervous system with supervised exercise for instance, we have patients with dizziness and exercise intolerance use stationary bikes rather than a treadmill — for safety. This step is crucial because it increases cerebral blood flow and unleashes a cascade of neurochemicals that help your brain adapt and perform during the next phase.
It also forces your brain and ANS to work together to supply the brain with the blood it needs. The activate phase is when you complete most of your therapies. These are designed to force your brain and nervous system to adapt to increasingly difficult challenges. Finally, the recover phase gives you a chance to destimulate and engage your parasympathetic nervous system before repeating the cycle.
This helps your body relearn how to balance the sympathetic and parasympathetic branches of your nervous system while giving your brain a chance to recuperate before the next round of therapy.
