High-Impact Sports Linked to 4-15-Fold Increased MND/ALS Risk

The potential link between head trauma and long-term neurodegeneration is a subject of increasing clinical relevance. While the etiologies of conditions like amyotrophic lateral sclerosis (ALS) are multifactorial, evidence has suggested that environmental factors, including traumatic brain injury and repetitive head impacts, may contribute to their development [1, 2, 3]. Previous studies have specifically explored the association between participation in contact sports, such as American football and rugby, and an elevated risk of neurodegenerative diseases like ALS and chronic traumatic encephalopathy [4, 5]. This evolving body of research underscores the clinical need to identify specific exposures that may affect long-term neurological health in athletes [6, 7]. A recent comprehensive review now synthesizes the current epidemiological landscape, offering clinicians a clearer picture of the data linking sport-related trauma to motor neurone disease [8].
