Unraveling Concussion Symptoms: The 2023 Consensus Statement

Dr. Lowell Greib MSc ND CISSN

Concussions are a prevalent and often underestimated form of traumatic brain injury that can have lasting effects on an individual’s cognitive and physical well-being. In an effort to standardize the diagnosis and management of concussions, the medical community released the 2023 Consensus Statement, which provides updated guidelines on identifying and treating this common injury. In this article, we’ll delve into the symptoms of concussion as outlined in the 2023 Consensus Statement, offering insights into the latest understanding of this complex condition.

Before we explore the symptoms, let’s briefly recap what a concussion is. A concussion is a type of mild traumatic brain injury that occurs when a blow, jolt, or impact to the head causes the brain to move rapidly within the skull. This movement can lead to stretching and damage to nerve fibers, which can affect how your brain functions both chemically and structurally.

Recognizing the Symptoms:

**Physical Symptoms**

  • Headache: Persistent or worsening headaches are a common symptom of concussion and can range from mild to severe.
  • Nausea and Vomiting: Individuals may experience a sense of nausea or vomiting, often related to the disruption in normal brain function.
  • Dizziness and Balance Issues: Problems with balance, coordination, and dizziness are frequently reported post-concussion.

**Cognitive Symptoms**

  • Confusion: A state of mental fog or confusion may follow a concussion, making it challenging for individuals to concentrate or think clearly.
  • Memory Issues: Short-term memory problems are common, and individuals may struggle to recall events that occurred before or after the injury.
  • Slowed Reaction Time: A noticeable delay in responding to stimuli can be an indicator of a concussion.

**Emotional and Behavioural Symptoms**

  • Mood Swings: Concussions can affect an individual’s emotional state, leading to mood swings, irritability, or increased emotional sensitivity.
  • Depression and Anxiety: Some individuals may experience symptoms of depression or anxiety in the aftermath of a concussion.
  • Sleep Disturbances: Changes in sleep patterns, such as insomnia or excessive sleepiness, may occur.

**Sensory Symptoms:**

  • Sensitivity to Light and Noise: Concussion can heighten sensitivity to light and noise, causing discomfort for the affected individual.
  • Blurred Vision: Vision problems, including blurred or double vision, may be present post-concussion.

**Delayed Symptoms:**

  • Post-Concussion Syndrome: In some cases, symptoms may persist beyond the expected recovery period, leading to a condition known as post-concussion syndrome. This may involve persistent headaches, dizziness, and cognitive difficulties.

Seeking Medical Attention:

It is crucial to emphasize that anyone suspected of having a concussion should seek medical attention promptly. The 2023 Consensus Statement underscores the importance of individualized assessment and management plans, as each concussion is unique and may require different approaches to recovery. A faster evaluation allows for individualized care early in recovery.

The 2023 Consensus Statement represents a significant step forward in the understanding and management of concussions. Recognizing and addressing the symptoms promptly is essential for a successful recovery and to minimize potential long-term consequences. If you or someone you know experiences a head injury and displays any of the aforementioned symptoms, consult with a healthcare professional for a thorough evaluation and appropriate guidance on the road to recovery.
