In some cases a concussive injury can produce a mild brain injury. A concussion is a temporary injury. However, a concussive injury can lead to stretching and tearing of nerve fibers in the brain, producing longer-term effects. These injuries usually don’t show up in CAT scans and neurological examinations. In some cases, since the person never “lost consciousness” a full neurological exam never takes place.

The term HEAD INJURY refers to an injury to the BRAIN which is usually the result of an accident, or sometimes an assault. Often the injury results froma blow to the head such as may be suffered in an automobile accident, a fall or a gunshot wound. The injury may also occur as a result of lack of oxygen (such as in drowning), or as a result of lack of blood supply to the brain (such as following a cardiac arrest). See similar questions...

When a TBI occurs but the skull does not break, it is called a "closed head injury." This is the most common type of TBI. A concussion is a form of a closed head TBI. Brain injuries may also occur when an object penetrates the skull and enters the brain tissue. In addition to causing a direct injury to the brain, a skull fracture may also permit an infection to grow in the brain fluid, causing further damage to the brain. See similar questions...

A survivor's degree of consciousness is often used to determine the severity of his/her brain injury. Instruments such as the Glasgow Coma Scale (GCS) use the survivor's visual, motor, and verbal responsiveness to measure level of consciousness. A copy of the GCS can be found in our Glossary section. Scores of 8 or below are considered to represent a true coma (no eye opening, no response to simple commands, and unable to communicate) and to indicate a severe brain injury.

Yes, in contrast to the short time it takes to injure the brain, recovery is measured in weeks, months and even years. Recovery is most rapid shortly after the injury and slows down with the passage of time. Many people with severe head injuries end up with almost no noticeable problems, but others require constant care for the rest of their life. See similar questions...

The more severe head injuries are followed by a period of COMA lasting from seconds to a few months or more. People begin to wake up from coma when they can open their eyes, speak, or begin to obey commands. See similar questions...

In the most mild of cases, the brain still gets bruised in much the same way your leg might get bruised if you bump into a coffee table. However, the head and the brain is pretty resilient and it can usually handle that injury without much effort. Some times people can get a really tremendous blow on the head and it not have any external effect. Again, much depends of the location of the injury and the brain's ability to compensate.

open head brain injury is an occurrence where a foreign object penetrates the skull and punctures the brain, making it susceptible to infection. Open head brain injuries typically cause impairment to the functions that the injured part of the brain controls. See similar questions...

A closed head brain injury is an accident where there is trauma to the brain that does not result in a skull fracture. Closed head injuries are somewhat difficult to diagnose because there may be no physical signs of injury. Like other brain injuries, closed head injuries must be treated immediately.

A concussion is defined as "an immediate acceleration, deceleration, or stopping event causing temporary or permanent damage to the structures of the head." The vestibular system, and more specifically the labyrinthine structures within the inner ear, appear to be more susceptible to blunt head trauma than the skull or brain. Symptoms from both types of concussions can be similar; however, the treatment for each is significantly different. See similar questions...

A concussion results from a blow to the head which causes the brain to strike the skull. A concussion does not cause any structural damage to the brain, but can cause temporary loss of functioning. Headaches, memory loss and sleep disturbance may be some of the problems suffered after such an injury. See similar questions...

Anytime you connect something to your helmet you will lose some mobility. Mobility with Isaac® occurs in two stages. The first is the natural movement of the mechanical connections and the rollers on the belt. This is adequate for most racing — checking mirrors and flag stations — and is equal to, or better than, what you would get with other products that are tightened enough to perform as well as Isaac®.

Approximately 1.5 million people per year will sustain a head injury in the United States.  Of those, the majority are males.  The two highest age groups at risk are 0 to 4 years of age and 15 to 19 years of age.  Leading causes are falls, motor vehicle accidents, gun shot wounds, and assaults.

Mild head injury presents with no or brief loss of consciousness.  Initial testing may appear normal.  The individual may appear dazed or mildly confused.  Symptoms include headache, irritability, sleep disturbance, fatigue, pain, memory problems, and depression.  Symptoms may last days or months. See similar questions...

Moderate head injury refers to situations with a loss of consciousness ranging from a few minutes to a few hours.  Confusion may last for days or weeks.  Cognitive, physical, and behavioral impairments may last for months or be permanent. What is a Severe Head Injury?Severe head injury may be characterized by an extended period of unconsciousness (coma), lasting days to months. See similar questions...

Is there other treatment or medication? I was told that Tegretol is used to treat seizure disorder and CDI. Yes, there are other medications that work quite well in CDI. One is Tegretol. Another is chlorpropamide. Both can be taken by mouth and may have side effects but they are usually not serious. CDI may result in increased loss of water from skin or lungs (so called insensible loss) but it does not manifest as an appreciable increase in perspiration. See similar questions...

open head injury occurs when an external object (e.g., a bullet) penetrates the skull and damages brain tissue in its direct path. These types of injuries often cause predictable and specific impairments due to the localized nature of the damage. A closed head injury is caused by rapid deceleration or striking the head against another object. The type and severity of the resulting impairments are unpredictable because of the diffuse nature of secondary tissue damage. ^ return to top ^ See similar questions...
