What Is a Concussion?


A concussion is a mild traumatic brain injury caused by a direct or indirect hit to your head or body.

Your brain sits inside your skull surrounded by fluid. When your head takes a hit — as often happens in contact sports — your brain shifts or shakes around inside the skull.

The impact damages your brain cells, causing chemical and cellular changes in the brain.

Concussion Baseline Scans and Protocol


Regenerative Complete has partnered with Emotion to be a Concussion Assessment Center in Knoxville, TN. Utilizing WAVi Scan technology, we can provide a non subjective concussion test with results interpreted by a Neurologist. The WAVi Scan produces a detailed report that allows Regenerative Complete to start the diagnosis process and treatment protocols to get you back to health.


Concussion causes and risk factors


The most common cause of a concussion is a hard, direct hit to the head in contact sports. It can also happen from an indirect hit that causes your head to jerk, like when you get whiplash.

Sports that increase an athlete's risk of head trauma include:

  • Football

  • Hockey

  • Soccer


Younger athletes and females tend to take longer to get better from concussions.

Concussion side effects and complications


Side effects of a concussion cause changes in how the brain functions, such as reduced reaction time. This can increase your chance of getting another concussion if you return to play before seeking treatment.

Repeated concussions can cause problems such as lasting cognitive issues.

No athlete should return to the game until all symptoms are gone and a doctor has cleared him or her to play.

Fast facts on concussions

  • Usually, concussions are caused by a jolt or blow to the head.

  • Some research shows that the effects of a concussion on cognitive ability can still be measured 30 years later.

  • Initial symptoms might include dizziness, slurred speech, and amnesia



Signs of concussion may not be noticeable straight away.


Immediate signs


Signs of a concussion that can be noticed immediately include:

  • loss of consciousness

  • confusion

  • headache

  • slurred speech

  • dizziness

  • ringing in the ears

  • nausea

  • vomiting

  • amnesia

  • tiredness


Non-immediate symptoms


The following symptoms may not be noticeable for several hours or even days:

  • amnesia

  • depression

  • disturbed sleep

  • sensitivity to sounds

  • irritability

  • lack of concentration or focus

  • moodiness

  • sensitivity to light


Serious symptoms that need immediate attention


The following signs and symptoms of concussion may be linked to a more serious injury, and immediate medical help should be sought:

  • prolonged headache

  • prolonged dizziness

  • dilated of different-sized pupils

  • prolonged nausea and vomiting

  • consistent memory loss

  • ringing in the ears

  • loss of sense of smell or taste

In children


Concussion signs and symptoms are most difficult to detect in very young children because they cannot explain how they feel. Signs may include:

  • lethargy and listlessness

  • irritability

  • changing sleeping patterns

  • altered appetite

  • walking or standing unsteadily, or any signs of balance and dizziness problems


Serious signs in children

The following signs usually mean the child needs immediate medical attention:

  • loss of consciousness

  • after attempting to stem the bleeding, a cut continues to bleed

  • any change in the way the child walks

  • bleeding from the ears or nose

  • blurred vision

  • confusion

  • continuous crying

  • seizure

  • discharge from the ears or nose

  • dizziness

  • loss of appetite

  • prolonged headache

  • prolonged irritability

  • prolonged listlessness, fatigue, and lethargy

  • repeated or forceful vomiting

  • slurred speech

  • worsening headache




If an individual has experienced a severe jolt or blow to the head that has left them dazed, confused, or wobbly, they have concussion.

Determining the severity of the concussion is more difficult because the signs may not be evident. Amnesia and confusion on the field after injury may be as important, if not more important, in making a return-to-play decision. Our Practitioner will ask the patient details about the trauma. It may be necessary to question the people who accompanied the patient.


A neurological examination will also be done, which will include evaluating the following factors:

  • balance

  • concentration

  • coordination

  • hearing

  • memory

  • reflexes
