Current controversies in neurology subspecialty education: Insight from clinical neurophysiology.

Neurology subspecialty training and certification are in the midst of rapid transformation, with steady expansion in subspecialty fellowship and certification options and increased requirements over the past 15 years. This includes new epilepsy, neuromuscular medicine, and sleep medicine certification and training via the American Board of Psychiatry and Neurology (ABPN) and Accreditation Council for Graduate Medical Education (ACGME) and >200 new fellowship programs in 8 subspecialties accredited by the United Council for Neurologic Subspecialties (UCNS) since 2006.1 In response, the American Academy of Neurology (AAN) has published a position statement with a proposed unified fellowship timeline.2 This period has also seen the advent of Maintenance of Certification (MOC) for ABPN specialties and subsequent changes in the MOC process. In this context of rapid change and controversy in subspecialty education and certification, the article by Juul et al.3 on the recent history and current status of clinical neurophysiology (CNP) is particularly timely.
