What is the prevalence of Traumatic brain injury (TBI)?

Traumatic brain injury (TBI) is a common global health concern, with an estimated 69 million individuals worldwide sustaining a TBI each year. While it is not classified as a rare disease, the long-term disability resulting from a Traumatic brain injury varies significantly, and many cases go unreported, making exact prevalence figures difficult to track.

Is Traumatic brain injury considered a rare disease?

No, Traumatic brain injury is not considered a rare or ultra-rare condition; it is a major public health challenge. According to a systematic review published in The Lancet Neurology, the global annual incidence is approximately 939 per 100,000 people. However, these figures likely underestimate the true burden of Traumatic brain injury, as many mild cases—often referred to as concussions—are never treated in clinical settings or recorded in national health databases.

Who is most affected by Traumatic brain injury?

Epidemiological data indicates that the risk of Traumatic brain injury is not distributed equally across the population. Key trends include:

• Gender: Males are generally more likely to sustain a Traumatic brain injury than females, often due to higher rates of occupational hazards and contact sports.


• Age: Incidence peaks occur in two groups: young children (often due to falls) and older adults (due to falls and comorbidities).


• Geography: Low- and middle-income countries often report higher rates of Traumatic brain injury related to traffic accidents compared to high-income nations.

Why is accurate data for Traumatic brain injury difficult to obtain?

Determining the precise number of people currently living with the long-term effects of Traumatic brain injury is challenging. Many individuals experience "invisible" symptoms like cognitive fatigue or mood changes that may not be formally diagnosed as related to a previous Traumatic brain injury. At DiseaseMaps.org, 23 people have joined our community to share their personal experiences, providing a crucial, real-world perspective that clinical statistics alone often fail to capture regarding the lived reality of recovery.

Next steps

• Consult a neurologist or physiatrist to develop a personalized neuro-rehabilitation plan.


• Connect with the Traumatic brain injury community on DiseaseMaps.org to share experiences and coping strategies.


• Monitor for long-term complications, such as changes in memory, sleep, or emotional regulation.
