Understanding Concussions: Basics and Beyond

Concussions, often considered the mildest form of Traumatic Brain Injury (TBI), are a common concern in both sports and daily life. Despite being classified as “mild,” the effects of a concussion can be significant and require proper care and attention. At Revivo, our physiotherapy and neurology clinic in Toronto, we emphasize the importance of understanding concussions not just as isolated incidents but as injuries that can have lasting impacts on brain health. This post aims to deepen the understanding of concussions, exploring what they are, how they occur, and the importance of appropriate management for optimal recovery.

What is a Concussion?

A concussion is a type of brain injury that results from a blow to the head or a sudden, forceful movement that causes the brain to move within the skull. This movement can lead to changes in brain function, manifesting as a variety of physical, cognitive, and emotional symptoms. Concussions are unique in that they typically do not show visible signs of brain damage on standard imaging tests, making them particularly challenging to diagnose and manage.

Causes of Concussions

Concussions can occur in any situation where a forceful impact to the head or body occurs. Common causes include:

  • Sports injuries, particularly in contact sports like football, hockey, and soccer
  • Falls, especially among young children and older adults
  • Motor vehicle accidents
  • Physical assaults
  • Recreational activities such as cycling or skiing

Symptoms of Concussions

Symptoms of a concussion can vary widely from person to person and may include:

  • Headache or a feeling of pressure in the head
  • Dizziness or balance problems
  • Nausea or vomiting
  • Blurred or double vision
  • Sensitivity to light or noise
  • Confusion or feeling “foggy”
  • Difficulty concentrating or remembering
  • Changes in mood, behavior, or personality

It’s important to note that symptoms can appear immediately after the injury or may develop over several hours or days.

The Importance of Proper Management

Proper management of a concussion is critical to ensure a full recovery and to prevent further injury. The initial step after sustaining a potential concussion is to remove the individual from play or activity and seek medical evaluation. Rest, both physical and cognitive, is often recommended in the early stages to allow the brain to heal.

Gradual return to daily activities and sports should be carefully managed according to guidelines provided by healthcare professionals. Premature return to activities that pose a risk of head injury can lead to prolonged symptoms or increase the risk of sustaining another concussion.

Long-Term Implications

While most people recover from a concussion with appropriate care, some may experience persistent post-concussive symptoms or develop long-term complications such as post-concussion syndrome, increased susceptibility to future concussions, and in rare cases, chronic traumatic encephalopathy (CTE).

Prevention Strategies

Preventive measures include wearing appropriate protective gear during sports and recreational activities, ensuring safe play and work environments, and education on concussion awareness and proper techniques to avoid head injuries.


Understanding the basics and beyond of concussions is essential for everyone, from athletes and coaches to parents and individuals engaged in daily activities. At Revivo, we’re committed to providing expert care for those affected by concussions, offering comprehensive evaluation, treatment, and support for a safe and full recovery. By fostering awareness and promoting effective management strategies, we aim to minimize the impact of concussions and support the long-term brain health of our community members.
