Electrodiagnostic Assessment of Motor Neuron Disease
Motor neuron diseases involve degeneration of motor neurons in the brain (upper motor neurons), brain stem, and spinal cord (lower motor neurons). Symptoms vary depending on the degree of upper and lower neuron involvement, but progressive painless weakness is the predominant complaint. Motor neuron disease includes numerous specific disorders, including amyotrophic lateral sclerosis, spinal muscular atrophy, spinal bulbar muscular atrophy, and other inherited and acquired conditions. Abnormalities on nerve conduction studies, repetitive nerve stimulation, needle electromyography, and other electrodiagnostic techniques hel...

Electrodiagnosis of Common Mononeuropathies
This article addresses common mononeuropathies seen in the electrodiagnostic laboratory. The most common mononeuropathies —median neuropathy at the wrist (carpal tunnel syndrome), ulnar neuropathy at the elbow, and fibular (peroneal) neuropathy at the fibular head—are reviewed. The causes, clinical presentations, approached to the electrodiagnostic studies (including nerve conduction studies and needle electromyogr aphy), and the typical findings are discussed.

Electrodiagnostic Assessment of Plexopathies
Disorders of the brachial and lumbosacral plexus are complex and may occur as a consequence of trauma, compression, inflammatory disorders, malignant infiltration, or delayed effects of radiation therapy. An understanding of plexus anatomy and surrounding structures will allow the electromyographer to facilitate an efficient and comprehensive assessment of the plexus. A careful and thorough electrodiagnostic assessment allows for localization within the plexus and may provide important information about underlying pathology and prognosis.

Electromyography Case Examples
This article reviews five real cases with common reasons for referral to the neurophysiology laboratory with discussion of the approach to testing, interpretation of the result s, and practical decision-making points relevant to each case. The goal is to provide rationale for why specific studies were selected and how each was helpful in deriving the final diagnosis. (Source: Neurologic Clinics)

Electrodiagnostic Assessment of Polyneuropathy
This article focuses on principles of nerve conduction studies and needle electromyography applied to the electrodiagnosis of polyneuropathy. The components of the electrodiagnostic evaluation of polyneuropathy and the electrophysiological characteristics of axonal and demyelinating neuropathies and nodo-paranodopathies are reviewed.

Epilepsy
can now be diagnosed even in the presence of one unprovoked seizure or if the diagnosis of an epilepsy syndrome can be made. Epilepsy syndromes represent a specific set of seizure types and electroencephalographic and imaging features that tend to have age-dependent features, triggers, and prognosis. Epilepsy syndromes are the third and final level of epilepsy diagnosis, after classification of seizure and epilepsy types. Some epilepsy syndromes are self-limiting and pharmacoresponsive and others are pharmacoresistant and associated with poor developmental outcomes (epileptic and developmental encephalopathy). Features an...

The Finances of Neurology in a Major Children's Hospital
Child neurology programs can be net margin generators for children's hospitals. The relative value unit (RVU) expectations for child neurologists are heavily influenced by proceduralists (neurophysiologists, Botox injectors, and so forth) and means in most RVU data sets are not realistic expectations for Evaluation and Management coding, outpatient neurologists. Yet each neurologist has a net revenue/expense ratio of 1.97 for a hospital neurology enterprise, so each of the neurologists generates nearly twice their salary for the hospital. Downstream revenue is even more impressive. Each neurologist generates about $2,000,0...

Neurology in a Pandemic
The adaption of online or virtual technologies to deliver care, to meet professionally, and to interview has transformed child neurology. Although these technologies were brought to bear out of necessity, it is hoped that in a postpandemic world, these useful tools will continue to benefit the field. Here we discuss the tools and their future. (Source: Neurologic Clinics)

Novel Treatments and Clinical Research in Child Neurology
The molecular understanding of the pathogenic mechanisms responsible for neurologic diseases of children has led to a remarkable period of research that addresses the root causes of diseases. The promise of this research has been realized with cures and treatments that correct underlying deficiencies. The breakneck rate at which new research is being proposed promises to usher in a transformation of child neurology from a diagnostic and supportive field into an interventional one. Training child neurology residents in clinical research and therapeutic intervention is increasingly important to assure the ongoing ability to ...

Genetics in Epilepsy
This article provides an overview of the major classes of genes associated with epilepsy phenotypes divided into functional categories along with the recommended work-up and therapeutic considerations. Gene discovery in epilepsy supports counseling and anticipatory guidance but also opens the door for precision medicine guiding therapy with a focus on those with disease-modifying effects.
