Anoxic brain injury is not an injury triggered by a blow to the head. However, it is an injury that happens due to insufficient oxygen reaching the brain. Although the death of cells is a normal process in the human body, the simultaneous destruction of several numbers of cells can leave an individual with diminished brain function. Anoxic brain injury becomes fatal in the event the oxygen deprivation continues.
Causes of Anoxic brain injuries
Anoxic brain injury happens when anything deprives the brain of oxygen. The following are some general causes which include;
People have different brains, and therefore, the level of oxygen deprivation depends on the injury. Although the causes of anoxic brain injury hinder the transportation of oxygen to the brain, there are specific triggers that completely block the supply of oxygen to the brain.
Averagely, the brain can survive about four minutes without oxygen. Therefore, one needs to act immediately during stroke or when they experience an injury that cuts off oxygen to the brain.
Brain damage can begin after 30 seconds of oxygen deprivation. After two minutes, damage to the brain becomes almost inescapable. Prompt medical attention is required to help reduce the chanced of potential long-term harm.
Signs and symptoms
There are telltale symptoms that are evident immediately after the occurrence of anoxic brain injury. They include;
Anoxic brain injury can result in varying long-tern effects. These effects depend on the part of the brain affected. For example, if the injury affects the area that controls speech, the individual may experience difficulty in speaking or remembering words. There are several symptoms of anoxic injury. One person’s symptoms may be different from another person’s. Common sign to watch out for include;
The extent of Anoxic brain injury occurs in four categories. The classification provides insight to long-term prognosis of the brain injury;
Treatment and prognosis
Treatment often focuses on the identification of the cause of injury and prevention of possible recurrence immediately after an anoxic brain injury. For example, a stroke may be caused by a blood clot or any other cardiovascular-related issue that may be prevention by the use of blood thinners and a change in lifestyle. After this, the prognosis of the injury will depend on the degree of injury, access to health care, age, and adherence to a recovery program. Some of the ways that may be used to enhance the outcome of the treatment include;
