Mild TBI/ Concussion: Introduction

Mild TBI is also known as concussion.

Mild TBI is a traumatic brain injury - an injury to the brain caused by an external physical force.

The signs and symptoms of a mild TBI are variable, non-specific and may be subtle - including such things as confusion, disorientation, memory impairment, balance disturbance or motor incoordination.

Recognising and diagnosing mild TBI is important for treatment and achieving the best outcomes.

Conversely not recognising and diagnosing mild TBI can be detrimental because subsequent actions may make the injury worse, e.g. continuing to play sport with a concussion.

The nature and degree of injury to the brain can vary significantly from one person to another. While most make a full recovery some do not.

Some people's symptoms subside within 48 hours. Other have symptoms persisting greater than a couple of weeks; and these require careful assessment and reassessment.

Some people's symptoms last months. The majority of people with post concussion syndrome recover completely in 3 to 6 months.

Some people do not fully recover and have life-time impairments.
