What is the prevalence of Acquired Brain Injury (ABI)?

Acquired Brain Injury (ABI) is a common, non-degenerative condition with an estimated global prevalence of over 69 million new cases of traumatic brain injury (TBI) occurring annually. Because ABI encompasses a broad spectrum of injuries—including both traumatic and non-traumatic causes—it is considered a widespread public health concern rather than a rare disease, though accurate tracking remains difficult due to significant underdiagnosis in mild cases.

How common is Acquired Brain Injury (ABI) globally?

While Acquired Brain Injury (ABI) is not classified as a rare disease, precise global prevalence statistics are challenging to capture. Research published in The Lancet Neurology estimates that approximately 69 million individuals worldwide sustain a traumatic brain injury each year. When including non-traumatic causes such as strokes, hypoxia, or infections, the total number of people living with the long-term effects of an Acquired Brain Injury (ABI) is significantly higher, though data varies by region and diagnostic reporting standards.

Are there demographic patterns in Acquired Brain Injury (ABI)?

Epidemiological data for Acquired Brain Injury (ABI) shows distinct trends regarding age and gender:

• Gender: Males are statistically more likely to sustain a traumatic Acquired Brain Injury (ABI) than females, particularly in younger age groups.


• Age: Incidence rates often peak in two groups: young adults (ages 15–24) due to accidents, and the elderly (ages 65+) due to increased risks of falls.


• Variations: Geographic prevalence is heavily influenced by local infrastructure, access to trauma care, and the prevalence of infectious diseases that can cause non-traumatic brain injury.

Why is it difficult to track the prevalence of Acquired Brain Injury (ABI)?

The primary challenge in mapping the true impact of Acquired Brain Injury (ABI) is the high rate of underdiagnosis. Many individuals experience "mild" injuries—such as concussions—that may not result in hospitalization or formal clinical documentation. At DiseaseMaps.org, 15 community members have shared their experiences with Acquired Brain Injury (ABI), providing a vital, real-world perspective that complements clinical data by highlighting the lingering, often invisible, challenges of living with this condition.
