Understanding Concussion
A concussion is a type of mild traumatic brain injury (mTBI) caused by a bump, blow, or jolt to the head or body that causes the brain to move rapidly inside the skull. This sudden movement can cause the brain to bounce around or twist, creating chemical changes in the brain and sometimes stretching and damaging brain cells.
Concussions are common in contact sports such as football, hockey, and soccer, but they can also occur during everyday activities like falls, car accidents, and playground injuries. It’s important to note that concussions can occur even without a direct hit to the head; any force that causes the head and brain to move quickly back and forth can lead to a concussion.
Definition and Causes
A concussion is a complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces. Common causes of concussions include:
- Direct trauma to the head, such as from falling, getting hit, or being in an accident
- Rapid acceleration-deceleration of the head, such as in whiplash injuries or blast injuries
It’s crucial to understand that concussions can occur without loss of consciousness, and external signs of head trauma, such as bleeding, may be absent in many cases.

Sleep-Related Symptoms
Concussions can also disrupt an individual’s sleep patterns, leading to:
- Drowsiness or fatigue
- Sleeping more or less than usual
- Difficulty falling asleep or staying asleep
It’s important to note that concussion symptoms can vary from person to person and may not always be immediately apparent. Some symptoms may develop hours or even days after the initial injury. Children and teens may have difficulty articulating their symptoms and may simply say they don’t feel right.
If you suspect that someone has sustained a concussion, it’s essential to seek medical attention immediately. A healthcare professional can properly evaluate the individual and provide appropriate treatment recommendations. They may also recommend monitoring the person for any worsening or new symptoms.
In rare cases, a dangerous collection of blood (hematoma) can form on the brain after a concussion, which may require emergency medical intervention. Signs of a potentially life-threatening situation include:
- One pupil larger than the other
- Drowsiness or inability to wake up
- A headache that gets worse and does not go away
- Slurred speech, weakness, numbness, or decreased coordination
- Repeated vomiting or nausea, convulsions, or seizures
- Unusual behavior, increased confusion, restlessness, or agitation
- Loss of consciousness
By familiarizing yourself with the various symptoms of concussion and knowing when to seek medical help, you can play a crucial role in ensuring the safety and well-being of those around you.
Diagnosing Concussions
Diagnosing a concussion involves a comprehensive evaluation by a healthcare professional. This assessment includes a thorough medical evaluation, neurological examination, cognitive testing, and in some cases, imaging tests. The goal is to accurately identify the presence of a concussion and determine the severity of the injury.
The medical evaluation begins with a detailed review of the patient’s medical history and the circumstances surrounding the injury. The healthcare professional will inquire about the mechanism of injury, any loss of consciousness, and the presence of concussion symptoms such as headache, dizziness, confusion, and memory problems.
During the neurological examination, the healthcare professional assesses the patient’s vision, hearing, strength, sensation, balance, coordination, and reflexes. This examination helps identify any focal neurological deficits or signs of more severe brain injury.
Cognitive testing is an essential component of concussion diagnosis. It evaluates the patient’s memory, concentration, attention, and ability to process information. Commonly used tools include the Standardized Concussion Assessment Tool (SCAT) and the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). These tests provide objective measures of cognitive function and can help track recovery over time.
Imaging tests, such as computed tomography (CT) scans or magnetic resonance imaging (MRI), are not routinely used to diagnose concussions. However, they may be ordered if there are concerns about more severe brain injury, such as skull fractures or intracranial bleeding. Advanced imaging techniques, such as diffusion tensor imaging (DTI) and functional MRI (fMRI), are being researched to detect subtle changes in brain structure and function following a concussion.
It is important to note that concussion symptoms can evolve over time, and some individuals may not experience symptoms immediately after the injury. Therefore, a concussion diagnosis may require multiple evaluations and close monitoring of the patient’s symptoms and cognitive function.
In addition to the clinical assessment, healthcare professionals may also consider risk factors that can influence concussion recovery, such as a history of previous concussions, learning disabilities, and mental health conditions. This information helps guide individualized management and return-to-play decisions.
Accurate diagnosis of concussions is crucial for ensuring appropriate management and preventing premature return to activities that may exacerbate symptoms or increase the risk of further injury. Healthcare professionals trained in concussion evaluation and management, such as sports medicine physicians, neurologists, and neuropsychologists, play a vital role in the diagnostic process.
In summary, diagnosing a concussion involves a comprehensive evaluation that includes a medical evaluation, neurological examination, cognitive testing, and potentially imaging tests. This multifaceted approach helps identify the presence of a concussion, assess its severity, and guide appropriate management strategies to promote optimal recovery and prevent long-term consequences.
Treatment and Recovery
Treatment for concussion focuses on providing the brain with adequate time to heal while managing symptoms. The primary approach involves a period of rest followed by a gradual return to activities. Healthcare providers work with patients to develop individualized treatment plans based on the severity of the concussion and the specific symptoms experienced.
Rest and Gradual Return to Activities
Immediately after a concussion, it is crucial to allow the brain to rest and recover. This involves both physical and cognitive rest. Patients are advised to avoid activities that may exacerbate symptoms, such as physical exertion, reading, watching television, or using electronic devices. The duration of rest varies depending on the individual and the severity of the concussion.
As symptoms improve, patients can begin a gradual return to activities under the guidance of their healthcare provider. This process typically involves a step-wise approach, starting with light activities and progressively increasing the intensity and duration as tolerated. It is important to monitor symptoms during this process and adjust the activity level accordingly.
Pain Management
Headaches are a common symptom of concussion and can be managed with over-the-counter pain relievers such as acetaminophen. However, it is important to avoid medications like aspirin and ibuprofen, as they may increase the risk of bleeding. In some cases, prescription medications may be necessary to manage severe or persistent headaches.
