Chronic traumatic brain injury associated with boxing

Area of Science:

• Neurology
• Sports Medicine
• Neuroscience

Background:

• Chronic traumatic brain injury (CTBI) affects approximately 20% of professional boxers.
• Risk factors include prolonged career, early retirement, high bout frequency, poor performance, and APOE genotype.
• Clinical presentation varies, encompassing motor, cognitive, and behavioral impairments, with severe cases termed dementia pugilistica.

Purpose of the Study:

• To review the epidemiology, clinical presentation, diagnosis, pathology, and treatment of CTBI in boxers.
• To highlight the similarities between CTBI and Alzheimer's disease.
• To emphasize the importance of prevention in managing CTBI.

Main Methods:

• Literature review of studies on CTBI in boxers.
• Analysis of clinical and pathological findings.
• Comparison of CTBI with other neurodegenerative diseases.

Main Results:

• CTBI is associated with cumulative head trauma in boxing.
• Pathological hallmarks of CTBI include neurofibrillary tangles and amyloid plaques, similar to Alzheimer's disease.
• Diagnosis requires identifying progressive neurological decline linked to head trauma, excluding other causes.

Conclusions:

• Prevention is the primary strategy for managing CTBI in boxers.
• Medications used for Alzheimer's disease and parkinsonism may offer symptomatic relief.
• CTBI represents a significant neurodegenerative risk in professional boxing.
