Concussion symptoms and signs of a traumatic brain injury

What Are Concussion Symptoms and Signs of Traumatic Brain Injury (TBI)​?​

When most people think of concussions, they mostly think about headaches, dizziness, and pain associated with the impact. Note that these can vary widely from person to person, and they may not always appear immediately after the injury. Here is a list of common signs and symptoms:

Physical Symptoms:

  • Headache

    This is one of the most common symptoms.

  • Nausea and vomiting

    Especially in the initial hours after the injury.

  • Dizziness or balance problems

    This is one of the most common symptoms.

  • Blurred vision or other visual disturbances

    Such as seeing double or sensitivity to light.

  • Sensitivity to noise

    Sounds may seem louder or more bothersome.

  • Fatigue or drowsiness

    Feeling unusually tired.

  • Ringing in the ears

    (Tinnitus).

  • Loss of consciousness

    Though not always present.

Cognitive Symptoms:

  • Confusion or feeling "foggy"

    Difficulty thinking clearly.

  • Difficulty concentrating or focusing

    Trouble paying attention.

  • Memory problems

    Difficulty remembering events before or after the injury.

  • Feeling dazed or stunned

    Appearing confused or disoriented.

  • Slowed reaction time

    Difficulty responding quickly.

Emotional or Behavioral Symptoms:

  • Irritability or increased emotional sensitivity

    Feeling easily agitated or upset.

  • Anxiety or nervousness

    Feeling worried or uneasy.

  • Sadness or depression

    Feeling down or hopeless.

  • Changes in sleep patterns

    Difficulty falling asleep, sleeping too much, or having disturbed sleep.

We are here to tell you that there are MANY things to consider in addition to the head, spine, and the muscles controlling them. For example, most people never think about blood pressure, heart rate changes, or the importance of blood sugar stability and the proper essential fatty acid intake during the acute phase.

Concussion symptoms with a brain stem injury

Concussion Symptoms with a
Brain Stem Injury

The first thing that happens in concussion, is that neurons are stretched, twisted, and injured at the areas of contact, and deep within the brain. The biggest problem with injuries deep within the brain is that the brain stem is injured and it houses long tracts that connect different parts of the brain. As a result, the symptoms that can occur when the brain stem is injured in a concussion as listed below:

Concussion Symptoms with a
Cerebral Cortex Injury

When you have Cortical injury or the areas of the cerebral cortex are injured (Frontal Lobe, Parietal Lobe, Temporal Lobe, Basal Ganglia), you often experience the following symptoms:

Concussion symptoms with a cerebral cortex injury
Concussion symptoms with a cerebellum injury

Concussion Symptoms with a
Cerebellum Injury

Injury to the Cerebellum with a concussion is very a bad thing, but it is also a very common occurrence with concussions. The cerebellum is called “the little brain” because it actually has more neurons than the entire brain itself. The cerebellum is involved in every aspect of information that comes into and/or leaves the brain. It controls the following:

Diagnostic Testing

For Concussion / TBI Treatment

Diagnostic testing for concussion or TBI treatment

Our diagnostic testing helps to determine which parts of the brain are involved, and to what extent. Our physical examination helps determine how well your brain is being fueled, and how hard we can push you to rehab. If you have concerns about any of these areas of your brain, please be sure to contact us.

If you or someone you know is suffering from a concussion or traumatic brain injury (TBI) and you are located in Chandler, Gilbert, or the Phoenix area, contact us immediately to start your concussion or traumatic brain injury (TBI) treatment and begin your healing journey today.

Common Causes of Concussions & Traumatic Brain Injuries

The most common causes of a concussion or traumatic brain injury (TBI) include:

Falling is a leading cause of concussion or TBI

Falls

The leading cause of TBIs, especially in young children and older adults, often occurring at home, on stairs, or in slippery areas.

Car accidents are a common cause of concussions and TBIs

Motor Vehicle / Car Accidents

Car, motorcycle, bicycle, and pedestrian accidents frequently result in head injuries due to sudden impact or whiplash.

Sports injuries are a common cause of concussion or TBI

Sports Injuries

Contact sports like football, hockey, soccer, and boxing, as well as recreational activities like skiing or skateboarding, pose a high risk of concussions.

Workplace accidents can cause concussion symptoms or signs of a TBI

Workplace Accidents

Construction sites, warehouses, and industrial jobs often involve risks of falling objects, slips, or machinery-related head injuries.

Violence and assault can cause concussion symptoms or signs of a TBI

Violence and Assault

Physical altercations, domestic violence, and gunshot wounds can result in serious head trauma.

Explosions can cause concussion symptoms and traumatic brain injury

Explosions and Blasts

Common among military personnel, blast-related injuries can cause TBIs even without direct head impact.

Concussion symptoms can be caused by a blow to the head

Being Struck by an Object

Accidental hits to the head, whether from falling debris, collisions, or swinging objects, can lead to concussions.

Even mild head injuries should be taken seriously, as symptoms may not appear immediately but can have lasting effects.
