The Cumulative Effect of Multiple Brain Injuries

Simple CBI GraphicThe neurological damage from sport-related concussions (minor traumatic brain injuries) are well-recognized events resulting in permanent brain injury in thousands of athletes each year. Common symptoms from a concussion might include headaches, dizziness, and slowed cognition.  These are the direct result of cellular damage to the neurons of the brain.

While the overt symptoms from these concussions typically resolve within several days to weeks, increasing scientific evidence suggests many athletes have persistent brain damage beyond the point of clinical recovery after injury.  This form of brain damage is known as brain or neuronal microdamage because it is visible only under a microscope.  It is not seen on common MRI or CT scans.

In many athletes, the damage is not completely repaired although the symptoms may seem to improve. Some of the damage remains only to accumulate with the microdamage from the next injury. In this manner, a series of seemingly innocent traumas can have the same cumulative effect on brain function as a single major trauma.  It is now known as cumulative brain injury or CBI (See Cunningham 2013).

The inability to recover from injury is related to abnormal functioning of a specialized white blood cell within the brain called microglia. The following video gives an overview of what is going on in the brain when an individual does not recover from a traumatic or non-traumatic injury.

Multiple Causes of Brain Microdamage

In addition to typical traumatic brain injuries, CBI can occur from a variety of other insults such as sub-concussive brain injuries or non-traumatic brain injuries.  Sub-concussive brain injuries (SCBI) are caused by the repetitive but mild head trauma experienced by a catcher or a soccer player for example.

Non-traumatic brain injuries (NTBI) can also mimic the effects of a TBI and result from events such as intensely negative emotional events (i.e., broken heart syndrome), infections, imbalances of intestinal bacteria, linoleic acid toxicity, vaccination, and cancer treatment.  Non-traumatic brain injuries can add to the cumulative damage of physically-traumatic injuries.

Sports-related CBI is also affecting the general population and is partially responsible for the growing incidence of conditions such as attention deficit disorder, restless leg syndrome, obesity, chronic depression, migraine headaches, and PTSD, Alzheimer’s and Parkinson’s Disease, and ALS.


Types of Injury Chart

Injuries are not completely recovering as they did several decades ago and it is believed this has to do with an abnormal behavior of a form of central nervous system white blood cell known as microglia.

When functioning normally the microglia are responsible for orchestrating the repair process in the brain after an injury.

But in individuals who are unable to recover from brain injuries, the microglia are spinning out of control, adding further to the brain damage, and ultimately preventing other repair mechanisms such as stem cells from restoring brain function.

Amazingly, Dr. Nemechek has discovered how to reverse this damaging process.  The Autonomic Advantage ™ Brain Recovery Program is the first program that can reverse underlying autonomic brain injury and symptoms that so many individuals suffer from.
