Increased motor tone, variations in movement quantity and speed, and involuntary motor activity are examples of extrapyramidal symptoms. They consist of two categories of symptoms and associated conditions: hyperkinetic (like Parkinson's disease) and hypokinetic (like Huntington's disease). This article discusses the main extrapyramidal movement disorders, the neurology behind extrapyramidal disorders, the importance of extrapyramidal signals in the major mental illnesses, and how to elicit extrapyramidal signs.
