Polyneuropathy, as the name suggests, is a nerve dysfunction encompassing many nerves throughout the body. Notably, though, it relates to peripheral nerves. There are many etiologies that can result in polyneuropathy. These include systemic disorders like cancer, diabetes, nutritional deficiencies, and autoimmune disorders, as well as environmental insults such as toxins, infections, and pharmacologic agents. The resulting deficits (e.g., related to movement or sensation) are dependent on the nerves involved. Often, the distal nerves (i.e., those in the feet or hands—a “stocking glove” distribution) are affected before those in the more proximal extremities or trunk. Physicians use a multimodal approach for diagnosis and treatment, including electromyography, nerve conduction studies, and laboratory tests. Treatment is often targeted at the underlying disorder, but physical therapy, drugs, and other measures may help if this is not successful.

Hard Topic
By Lucas F. on 16. July 2020 for Polyneuropathy

Hard topic, but the systematic approach is very helpful. He is a great at pointing out the relevant information about each of the topics. Everytime I see he is the teacher I know I'll not be losing my time.
