Some unusual sports-related neurologic conditions.

PURPOSE OF REVIEW: This article reviews some of the unusual sports-related neurologic disorders within the new and rapidly growing field of sports neurology that neurologists may encounter.

RECENT FINDINGS: Surfer's myelopathy is a potentially tragic disorder predominantly affecting novice surfers, leaving many who are affected by this condition with permanent paralysis. Neck-tongue syndrome is a rare primary headache disorder that can occur in athletes and nonathletes, and consists of paroxysmal neck and occipital pain and transient ipsilateral tongue numbness, triggered by sudden rotation of the neck. Athletes are also at risk for cervical arterial dissections, with golfers especially prone to vertebral rather than carotid dissections. Finally, "the yips" likely represents a form of occupational dystonia described in golfers.

SUMMARY: The syndromes described in this article range from relatively minor syndromes that cause discomfort or abnormal movement to potentially devastating cerebrovascular or myelopathic syndromes. Although the disorders described in this article are not common, they can affect individuals involved in sports at all levels, from the novice to the elite athlete, and may present to any neurologist. Neurologists should be aware of the potential for these syndromes to occur as a consequence of athletic activities in order to provide the most appropriate diagnosis, management, and counseling.
