Anoxic Brain Injury Treatment Rehabilitation, Anoxia Mind Damage (updated june 2009)

Anoxic brain injury occurs in when there is a lack of oxygen to the brain. Brain cell neurons will start to die off when the brain has gone without oxygen for over four minutes. Oxygen is extremely important for maintaining the functioning of your neurons.

For many people, this type of brain injury cannot currently be helped a great deal. However, new therapies are constantly being developed so this may not remain the case forever. New neurotechnologies may be used in the future to help repair brain damage. Japanese researchers have now used stem cells to synthesize brain tissue. This might allow injured patients to have their damaged or missing neurons replaced. Eventually tissue engineering may allow the replacement of brain tissue in practically any brain area. Trials are already beginning to test stem cells for stroke patients. So clinical trials to test stem cells for other brain injuries might not be that far behind. Brain surgery may become easy and safer by the use of more sophisticated robotic neurosurgeons.

There are also many brain stimulation therapies that could also be used to alter the brain's plasticity. Many of these techniques could be utilized for a variety of head injuries. Transcranial magnetic stimulation, for instance, has recently been used to awaken a coma patient. These are very powerful brain manipulation tools that can do all sorts of interesting and unique things. Ultrasonic neuromodulation may be another possible technique to non-invasively stimulate the growth of neurons in certain key brain regions. Transcranial direct current stimulation and deep brain stimulation are two other ways that could find increasing use in the future. These methods can selectively increase or decrease the activity of neurons in discrete brain regions. Many disorders are associated with maladjusted neuronal functioning.

Other scientists are developing new computer simulations of the brain. These computer simulations will likely be able to accelerate the development of new pharmaceutical drugs and manipulation techniques for disorders. It would allow researchers to test out therapies ahead of time before utilizing them on a real person's brain. A lot of the more ambitions simulations may actually be less than 10 years away from coming about. So they could definitely go a long way in helping scientists improve brain injuries.

Researchers have also been making new and improved brain-computer interfaces that may help people who are currently paralyzed. A brain-computer interface is able to take brain waves recordings from a person's mind. Those readings can then be translated into the movement or workings of an external device/object. This would enable a person who is "locked in" to be able to move a robotic arm, for example, solely by the manipulation of their own thought processes. Brain scanning technology is also getting better and can help those with brain damage in several ways. Brain imaging has been used to help doctors communicate with people who have undergone severe brain damage. MRI scans are becoming much higher in their resolution of detail can assess injuries much better.

Hyperbaric oxygen therapy can be used for a positive effect and helps somewhat for certain patients. A person may need to have some sort of brain injury rehabilitation depending on how bad their conditions is. Certain patients suffering from anoxic brain injury may need to be taken care of for 24 hours a day. A person may need to have a brain MRI or have other neuropsychological testing to diagnose the damage to their brain.

There are several different kinds of anoxia. One type is toxic anoxia. Toxic anoxia is actually caused by a variety of different blood toxins that reduce the amount of oxygen in the blood. Another is anemic anoxia which happens when the blood isn't able to carry enough oxygen. Finally there is anoxic anoxia which happens when no oxygen is being supplied to a person's brain. Any of these things can have many devastating consequences for a person even potentially leading to a loss of consciousness. Hypoxic brain injury is only a partial lack of oxygen to the brain.

The symptoms of anoxic brain injury can be quite varied and depend on how long a person is deprived of oxygen. Symptoms may include cognitive problems and a lack of coordination. The brain really requires both glucose and oxygen in order to function normally. Having a total lack of oxygen to a person's brain damages the brain cells in the cortex. When a person undergoes cardio-pulmonary arrest, a loss of consciousness may often occur in 10-15 seconds. Due to this, a person may have irreversible damage of the mind happening within 5 minutes. There is also hypoxic brain injury which refers to only a partial lack of oxygen. No two people have the same damage from anoxic brain injury and it depends on what region of the mind is affected. Better therapies for the mind are continually being developed as the field of neurotechnology progresses. They will likely help many people regain lost functioning in the future.

Hypoxic-Anoxic injury is also known as HAI. Oxygen is extremely important molecule that the body uses. The mind consumes approximately a fifth of all the body's oxygen supply. When there is a deprivation of the oxygen molecule then a resulting cascade of problems emerge. There can be a disruption in the activity of various neurotransmitters. Neurotransmitters are chemicals that enable signals to move across the synapse. Types of neurotransmitters include dopamine, norepinephrine and serotonin. Alteration of these neurotransmitters can have a substantial impact on a person's mood and psychiatric functioning. These chemicals activate specific receptor proteins in the post-synaptic neuron thus altering their firing pattern. Hypoxia can result in severe changes to these chemical brain messengers. The impact on human psychology and consciousness can be enormous.

The most common cause of hypoxia is the result of hypoxic-ischemic injury which is also named HII (stagnant anoxia). HII is the result of an event in the body that prevents enough oxygen from reaching the mind. A major cause of HII is actually cardiac arrest, but it can also be due to having a cardiac arrhythmia or a stroke.
