In this episode of Brain Injury Insider, host Michael Kaplen dispels some of the common myths surrounding brain injury and concussions.
In discussing brain injury with the public and with professionals, I frequently need to correct misinformation and myths that make understanding of the TBI more difficult.
Today, I would like to discuss and dispel some of these misconceptions.
For each myth, I am including a link in the text accompanying this video for authoritative discussion of these important concepts.
It has long been recognized by the Centers for Disease Control, The American Academy of Neurology, and other prestigious medical groups, that a concussion is a brain injury that can have life-long consequences. A concussion can result from a bump, jolt, or blow to the head. The signs and symptoms of a concussion are varied including physical, cognitive, emotional, and behavioral disturbances. The Centers of Disease Control’s website can provide detailed information: https://www.cdc.gov/traumaticbraininjury/get_the_facts.html
Although CT Scans and MRI scans are useful for determining brain bleeds, skull fractures and pressure within the skull and brain cavities, these scans are not sensitive enough to detect microscopic damage to nerve fibers within the brain resulting in tears, strains, bruising of nerve cells and chemical reactions that often take place following brain trauma. It is not unusual for the CT scan or MRI study to be normal in a patient with TBI.
The fact that a CT scan or MRI is negative does not rule out a traumatic brain injury.
Absence of proof is not proof of absence is a saying used by medical professionals when they discuss the limitations of these tests to rule out brain injury.

There is no need to lose consciousness to have sustained a concussion. A concussion can take place even without losing consciousness. Most concussions do not involve a loss of consciousness. The definition of a concussion includes being dazed or confused in the period immediately following the traumatic event. Some individuals may not remember all events immediately before or after the trauma.

You do not need to hit your head or have an object strike your head to sustain a brain injury.
You shake it, you break it is often said to describe the movement of the brain within the skull which can cause shearing, tearing, or stretching of nerve fibers. The inside of the skull contains many protrusions and sharp ridges which can cause damage to the soft and delicate brain fibers when the brain is thrust up against the interior of the skull.
Brain injury can also result from the rotational movement of the brain within the skull.

Brain injury of all types and severities can have long-term and even permanent consequences. Not everyone achieves a full recovery following a traumatic brain injury. The most recent and comprehensive studies have found symptoms of brain injury persist over a year following an injury.

Other comprehensive studies found an increased risk of developing
chronic cardiovascular, endocrine, neurological, and psychiatric disorders following brain trauma of any severity:

I will return in future episodes of The Brain Injury Insider to discuss and dispel other frequent myths about brain injury.
