Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) can be difficult to distinguish from autoimmune nodopathy. In this podcast, Dr. Saima Chaudhry (1) is joined from the Netherlands by Dr. Ruth Huizinga (2) and Dr. Maarten Titulaer (3), to discuss their article, "Clinical relevance of distinguishing autoimmune nodopathies from CIDP: longitudinal assessment in a large cohort". They start with explaining what an autoimmune nodopathy really is, patient features to look out for, and the typical testing process for identifying CIDP.

The cause of a nutritional neuropathy may not always be obvious when first examining a patient. Restrictive diets with roots in religious practices or personal preferences will be less familiar to neurologists than issues involving bariatric surgery or diseases of malabsorption, and can present as being not overtly malnourished. A recent review in JNNP details links between B-vitamin deficiencies and peripheral neuropathy, and discusses historical trends in the occurrence of nutritional neuropathies. The review's last author, Dr. Alexander Rossor (1), joins host Dr. Saima Chaudhry (2) to talk through how to approach this diagnosis.

How often do movement disorder specialists agree when classifying tics? A recent study published in JNNP explores this question with a two-stage approach, seeking a diagnosis from experts first based on video evidence alone and then following the provision of additional clinical data. The study's last author, Dr. Christos Ganos (1), joins host Dr. Saima Chaudhry (2) to discuss the results.
