Anoxic Brain Injuries
An anoxic brain injury occurs when there is a lack of oxygen going to the brain. When this oxygen deprivation occurs, brain cells can start to die within five minutes. Causes of anoxic brain injury can be blood clots, shock, heart problems, diseases, anemia and even lack of air at high altitudes. Coma, seizure and total loss of brain function can occur after several minutes. While rehabilitation can help some people with anoxic brain injury, many individuals with anoxic brain injury sustain persistent psychological and neurological problems.

    Anoxic brain injuries can be prevented by taking measures that reduce your risk of having the injuries or illnesses that can lead to oxygen deprivation. Carbon monoxide poisoning may be prevented by placing carbon monoxide detectors in your home. Chewing food slowly can help prevent choking. Drowning may be prevented by learning the basics of swimming and pool safety. Avoiding sources of high-voltage electricity can prevent electrocution. And eating healthfully and getting regular exercise can reduce your risk of cardiovascular disease.

    If you are recovering from an anoxic brain injury, you may be experiencing many cognitive, physical, and emotional symptoms. To manage these symptoms, it helps to have a team of rehabilitation professionals. Physical therapy, speech therapy, and occupational therapy may all play a part in your recovery and the management of your symptoms. Talking with a counselor can help you deal with any frustrations you may be having. Although the recovery process can be unpredictable, try to be patient. Improvements can be gradual and may occur over a period of months or years.

    Anyone with symptoms of an anoxic brain injury needs to be seen by a doctor immediately. The underlying cause of the injury - such as cardiac arrest, for example - needs to be treated right away. Appropriate life-support systems - like mechanical ventilation - must be administered as soon as possible to help stabilize the body. The longer a person is deprived of oxygen, the worse the prognosis is for a successful recovery.

    If you're caring for someone who has had an anoxic brain injury, keep in mind that the injury may cause emotional problems - like depression and irritability - as well as cognitive and physical ones. Recovery can be a slow, gradual, and often frustrating process. It can also be very unpredictable. Try to offer as much encouragement as possible. Support from loved ones and friends can go a long toward stimulating motivation and progress.

    An anoxic brain injury usually starts with a loss of consciousness. The person may then enter a state known as "wakeful unresponsiveness." In this state, they do not respond to any external stimuli, but they are not comatose either. If the person regains consciousness again, they can experience a whole host of cognitive and physical symptoms. Cognitive symptoms may include short-term memory loss, visual disturbances, decision-making problems, confusion, concentration problems, and linguistic difficulties. The physical symptoms they may experience include weakness in the limbs, coordination problems, abnormal movements, and difficulties performing sequential tasks. Other symptoms may include hallucinations, mood disorders, irritability, and agitation.

    An anoxic brain injury can be classified into one of four categories based on what caused the oxygen deprivation. The most common is stagnant anoxia, which occurs when an internal condition blocks an adequate supply of oxygen-rich blood from entering the brain. If the anoxic brain injury is caused by an insufficient supply of oxygen in the air, it's classified as anoxic anoxia. When the anoxic brain injury is caused by toxins or metabolites interfering with the ability to process oxygen normally, it's called toxic anoxia. Anemic anoxia occurs when there are not adequate levels of blood or hemoglobin to carry oxygen to your brain.

    Your doctor can diagnose an anoxic brain injury by assessing your medical history and performing a physical examination. Tests will be run to determine the cause of your anoxic brain injury. These may include an echocardiogram and an electrocardiogram to look for heart problems. An electroencephalogram, evoked potentials, and MRI can be used to check brain activity and look for brain injury. Your doctor may also order blood work to look for blood gases and to check your blood sugar level.

    There is no cure for an anoxic brain injury. Initially, the condition that caused the anoxic brain injury - like cardiac arrest, for example - can be treated. Any necessary life-support systems, such as mechanical ventilation, are also put into place. While these measures won't cure the anoxic brain injury, they can help to stabilize the body. Some research indicates that barbiturates - which reduce activity in the brain - may be beneficial during the first few days after the injury.

    Although recovery from an anoxic brain injury can be unpredictable, some factors can increase your likelihood for a more successful outcome. The less time you were unconscious and the less time you were deprived of oxygen, the better the outcome. In addition, being young can help. Research indicates that people under 25 years old have a higher likelihood of a successful recovery.

    Recovery from an anoxic brain injury can be unpredictable. It may take months to recover, or it may take years. It is also important to keep in mind that recovery may incomplete, with the person not fully regaining their pre-injury degree of functioning.
