Every year in
the USA, more than two million people sustain some form of traumatic
brain injury, with 1,000,000 being severe enough to be treated in
hospital emergency rooms.
Brain injury can be caused by an external physical force (also known
as traumatic brain injury, or TBI), resulting in:
* rapid acceleration or deceleration of the head;
* bleeding within or around the brain;
* lack of sufficient oxygen to the brain;
* toxic substances passing through the blood-brain barrier.
Any of these effects can result in an inadequate oxygen supply and
cause brain injury, resulting in temporary or permanent impairment
of cognitive, emotional and/or physical functioning.
The extent of damage from a traumatic brain injury (TBI) can vary
considerably, depending upon the severity of the injury and degree
of hypoxia (decrease in the oxygen supply to a tissue). Depending on
the extent of the brain damage, symptoms of TBI can be mild,
moderate or severe. Like the symptoms, the outcome of a brain injury
can be mild (complete recovery) to severe (permanent disability or
death).
HBOT can provide safe and efficient treatment to improve the
functional recovery of TBI survivors. With TBI, brain areas that are
injured are not receiving enough blood flow as a result of the
trauma. Tissue might get enough oxygen to survive but not enough to
be functional. Hyperbaric oxygen treatment can heal TBI patients by
regenerating, repairing and generating new blood vessels to the
injured parts of the brain. Recent research also indicates that
hyperbaric oxygen therapy (HBOT) can improve spatial learning and
memory in those with chronic traumatic brain injuries.
