Pituitary dysfunction due to sports injuries

Area of Science:

• Neurology
• Endocrinology
• Sports Medicine

Background:

• Traumatic brain injury (TBI) from sports can impair pituitary gland function.
• Even mild TBIs may lead to pituitary dysfunction, with symptoms mimicking general TBI effects.
• Pituitary hormone deficiencies can emerge or change over time, necessitating ongoing monitoring.

Purpose of the Study:

• To highlight the occurrence and clinical significance of pituitary dysfunction post-sports TBI.
• To discuss the challenges in managing growth hormone (GH) deficiency in athletes, including treatment efficacy and doping concerns.
• To identify the need for further research into sports-related pituitary dysfunction.

Main Methods:

• This study is a review of existing literature on TBI and pituitary function.
• It synthesizes information on clinical presentations, diagnostic considerations, and therapeutic controversies.
• It emphasizes the lack of large-scale, systematic studies in this field.

Main Results:

• Growth hormone (GH) deficiency is the most common pituitary issue after sports injuries.
• The efficacy of GH replacement therapy in athletes with post-TBI deficiency is debated.
• There is no consensus on monitoring these athletes due to potential GH doping.

Conclusions:

• Hypopituitarism must be considered in both acute and recovery phases after sports-related TBI.
• Further large-scale studies are essential for understanding epidemiology, pathophysiology, screening, and prevention.
• Addressing GH deficiency management and monitoring requires a clear strategy.
