American Clinical Neurophysiology Society

What American Clinical Neurophysiology Society does

The American Clinical Neurophysiology Society (ACNS) is a 501(c)(3) non-profit professional medical society founded in 1946 and headquartered at 555 E. Wells St., Suite 1100, Milwaukee, Wisconsin. Its mission is to advance the science, practice, and profession of clinical neurophysiology for clinical neurophysiologists, neurologists, trainees, neurosurgeons, and neurodiagnostic technologists across North America and select international markets. The organization develops and maintains clinical standards — most notably the ACNS Standardized Critical Care EEG Terminology (2021 version), which has demonstrated inter-rater reliability — and publishes the Journal of Clinical Neurophysiology (Wolters Kluwer, 6 issues/year, impact factor 1.673) as its official peer-reviewed venue.

ACNS operates a platform-plus-modules architecture: the core is the journal, the Annual Meeting & Courses (February, intermediate-to-advanced content), the Principles of Clinical Neurophysiology Courses (September, basic-to-intermediate), and the ACCME-accredited ACNS Learning Portal; the modules include CNP Bootcamp (a seven-week intensive for trainees launched in 2024), the In-Service Exam, the Institutional Training Package for residency and fellowship programs, six research consortia (including CCEMRC with 27 North American centers, Stereo EEG, NIOM, CoCANoT, Multimodality, and PedQuest), Special Interest Groups with monthly virtual meet-ups, and the ACNS Connect community platform.

The society monetizes through five primary streams: annual membership dues (June–May cycle), meeting and course registration (single course $145–$165; day pass $255–$285; all-access pass $475–$550 for members), the Wolters Kluwer journal partnership, Institutional Training Packages sold through program directors, and tax-deductible charitable donations to the Strategic, Educational, Research, and International Funds (donor levels from Bronze at $50 to Founders Circle at $25,000+). Distribution is direct-to-member via acns.org and ams.acns.org. ACNS also acts as an advocacy body, having successfully collaborated with CMS to create Medicare physician specialty code F6 for epileptologists (effective July 1, 2024) and co-publishing the Guidelines for Qualifications of Neurodiagnostic Personnel with AANEM, ASNM, and ASET in 2024.

Broad incumbents

• American Academy of Neurology (AAN): The largest US neurology professional society, serving as the broad incumbent in the same professional-education and CME space as ACNS. AAN publishes Neurology, hosts a much larger Annual Meeting, and offers overlapping subspecialty programming in clinical neurophysiology and epilepsy, competing for the same members.
• American Neurological Association (ANA): A broader academic neurology society that overlaps with ACNS's academic neurologist members and competes for high-end neurology meeting attendance and journal submissions.
• Child Neurology Society: Professional society for child neurologists, overlapping with ACNS's pediatric clinical neurophysiology audience (PedQuest Consortium). Competes for pediatric neurophysiology programming and CME dollars.

Direct peers

• American Epilepsy Society (AES): The US professional society for epileptologists, with significant overlap in target members (epileptologists, neurophysiologists) and overlapping Annual Meeting programming. ACNS collaborated with AES on the CCEMRC infrastructure grant in 2008 and jointly advocated for the F6 specialty code, making AES both partner and direct peer for ACNS epileptologist members.
• International League Against Epilepsy (ILAE): Global professional organization addressing epilepsy that overlaps significantly with ACNS's epileptologist member base, provides parallel standards and education (including EEG terminology work), and competes for the attention of epileptologists internationally.
• American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM): Co-author of the 2023 Joint Position Statement on Qualifications of Neurodiagnostic Personnel with ACNS. AANEM serves an overlapping neuromuscular/electrodiagnostic physician base and competes for neurophysiology education share-of-attention.
• ASET – The Neurodiagnostic Society: The professional society for neurodiagnostic technologists, partnering with ACNS on the joint QNP guidelines. ASET serves the technologist side of the same EEG/neurophysiology practice, with overlapping CME, certification, and advocacy activities.
• American Society of Neurophysiological Monitoring (ASNM): Co-author of the 2023 Joint Position Statement with ACNS and AANEM. ASNM focuses on intraoperative neurophysiological monitoring and serves a subset of the same clinician base (neuromonitoring practitioners) that ACNS addresses through its NIOM Consortium.

Regional players

• European Society for Clinical Neurophysiology (ESCN): The European counterpart to ACNS, offering equivalent clinical neurophysiology education, congresses, and journal (Clinical Neurophysiology, published by Elsevier). Functions as the regional peer outside North America, with member overlap and parallel standard-setting activity.

Others

• International Federation of Clinical Neurophysiology (IFCN): The umbrella federation of national clinical neurophysiology societies, of which ACNS is effectively a US national member. Relevant as an adjacent enabling/coordinating body for international EEG standards and education initiatives.
