Acute Parkinsonism: From viruses to non-viruses etiologies

Movement disorder emergency can be caused by several factors. This term defines a bradykinetic-rigid syndrome that develops over days or weeks. The most common etiologies are infectious and through immune mechanisms (viral, autoimmune, paraneoplastic), drug-induced, toxic-induced, and psychiatric causes. Cerebrospinal fluid analysis, toxicology, normal blood tests and imaging play a significantly important role in the evaluation and diagnostic of acute parkinsonism. Acute parkinsonism should always be treated as a medical emergency, as some forms of these diseases can be cured, depending on the underlying etiology.
