Clinical Neurophysiology Book Pdf

[Bonny Battaglino]

Clinicalneurophysiology is a medical specialty that studies the central and peripheral nervous systems through the recording of bioelectrical activity, whether spontaneous or stimulated. It encompasses both research regarding the pathophysiology along with clinical methods used to diagnose diseases involving both central and peripheral nervous systems. Examinations in the clinical neurophysiology field are not limited to tests conducted in a laboratory. It is thought of as an extension of a neurologic consultation. Tests that are conducted are concerned with measuring the electrical functions of the brain, spinal cord, and nerves in the limbs and muscles. It can give the precise definition of site, the type and degree of the lesion, along with revealing the abnormalities that are in question. Due to these abilities, clinical neurophysiology is used to mainly help diagnose diseases rather than treat them.[citation needed]

In some countries it is a part of neurology or psychiatry, for example the United States[1] and Germany. In other countries it is an autonomous specialty, such as Spain, Portugal, Italy, the United Kingdom, Finland, Sweden and Norway.

Hospitals that have neurologists and neurosurgeons tend to house clinical neurophysiology departments. Usually these tend to be larger hospitals that are able to employ more specialized staff units. In hospitals that possess clinical neurophysiology facilities, the major diagnostic modalities employed include:

There are two healthcare professionals who typically perform neurophysiological investigations in the UK. These are medical staff trained in clinical neurophysiology, and clinical physiologists who undertake four years of practical training whilst undertaking an honours degree. Physiologists perform the majority of EEGs, evoked potentials and a portion of the nerve conduction studies. They are then clinically reported either by the physiology staff or the medical staff. Their professional organisations are the British Society for Clinical Neurophysiology and the Association of Neurophysiological Scientists

Electrodiagnostic medicine is a subset of clinical neurophysiology. Electrodiagnostic medicine focuses only on the peripheral nervous system and not the central nervous system. Whereas a clinical neurophysiologist is trained to perform all the following studies EEG, intraoperative monitoring, nerve conduction studies, EMG and evoked potentials,[3] and electrodiagnostic physician focuses mainly on nerve conduction studies, needle EMG, and evoked potentials. The American Board of Psychiatry and Neurology provides certification examination in clinical neurophysiology. The American Board of Electrodiagnostic Medicine provides certification in EDX medicines.[4] The American Board of Clinical Neurophysiology certifies in electroencephalography (EEG), Evoked Potentials (EP), Polysomnography (PSG), Epilepsy Monitoring, and Neurologic Intraoperative Monitoring (NIOM).[5] In the US physicians typically specialize in EEG or EDX medicine but not both.[citation needed]

Hospitals that have neurologists and neurosurgeons tend to house clinical neurophysiology departments. Usually these tend to be larger hospitals that are able to employ more specialized staff units.Clinical neurophysiologists are responsible for analyzing and writing reports on tests that take place within the department. They must also interpret the results that they receive and convey this information to the doctor that referred the patient to the particular neurophysiologist. Many tests involve carrying out an EMG to read the evoked potential recordings. Nerve conduction recordings are extremely common as well.

The ABPN, in concurrence with the ABMS, established a Committee on Certification of Added Qualifications in Clinical Neurophysiology in October 1990. This was done to officially establish the field of clinical neurophysiology as a definite area of subspecialization in neurology and psychiatry and to provide a means of identifying properly trained and experienced clinical neurophysiologists. The first examination was administered in 1992.

The actual mechanics of certification of qualified candidates have been delegated by the Board to the Committee, which operates under the supervision of and in accordance with the policies of the Board.

Applicants for certification in clinical neurophysiology must be certified by the Board in general neurology or neurology with special qualification in child neurology by December 31 of the year prior to the examination. All applicants other than those initially admitted during the practice pathway period (1992-1999) are required to submit documentation of successful completion of one year of Accreditation Council for Graduate Medical Education (ACGME) accredited fellowship training in clinical neurophysiology that did not begin before the time general residency training in neurology or neurology with special qualification in child neurology, including time spent in combined training programs, was completed. The exposure to clinical neurophysiology given to neurology or child neurology residents as part of their basic training curriculum does not count toward the one year of training. All licensing and training requirements must be met by July 31 of the year of the examination.

The required one year of specialized training in clinical neurophysiology may be completed on a part-time basis as long as it is not less than half time; credit is not given for periods of training lasting less than one year except under special circumstances that must be approved by the ABPN Credentials Committee. In such cases, it is the responsibility of the applicant to provide detailed documentation from the perspective training directors, including exact dates (month/day/year to month/day/year) outlining training content, duties, and responsibilities. Each case is considered on an individual basis and documentation must be submitted to the Board prior to the start of training for special consideration.

If clinical neurophysiology (CNP) training was used to credential for certification in epilepsy during the practice pathway, it cannot subsequently be used to credential for certification in clinical neurophysiology.

This one-year fellowship is designed to enhance the technical skills and clinical application of clinical neurophysiology (CNP). The fellow will work closely with the Neuromuscular and Epilepsy services. Under the guidance of these services, the fellow will become proficient at the performance and interpretation of nerve conduction studies, electromyography, electroencephalography, long-term video/EEG monitoring and evoked potentials. Experience is also available for intraoperative monitoring (IOM) and sleep disorders, but these modalities are not available as an area of concentration. Clinical experience is obtained in our outpatient Epilepsy and Neuromuscular specialty clinics, as well as inpatient services. Additionally, the fellow may obtain exposure to nerve and muscle pathology and experience in biopsy interpretation.

At completion of the program, fellows are eligible for the American Board of Psychiatry and Neurology (ABPN) Clinical Neurophysiology Boards. Fellows may also be eligible for the Electrodiagnostic Medicine boards through the American Board of Electrodiagnostic and Neuromuscular Medicine (AANEM) or selected boards through the American Clinical Neurophysiology Society (see ABCN website abcn.org for available options).

For those that are interested, the CNP Fellowship may be coupled with an Epilepsy Fellowship for a two-year experience. The second year provides additional time for more in-depth pursuits, both clinical (e.g. in surgical epilepsy) and research.

General CNP fellows spend approximately three months on the Emory epilepsy service, three months with the Emory Neuromuscular service and the remainder of their time on either epilepsy or neuromuscular services at Grady Memorial Hospital.

CNP fellows with special emphasis in Epilepsy spend approximately 10 months gaining experience in EEG/epilepsy at either Emory or Grady and two months in another domain of clinical neurophysiology, typically in EMG/neuromuscular.
