Overview

Movement disorders are common conditions. The clinical presentation of movement disorders is complex and often has variation from person to person. Therefore, finding the correct diagnosis may be challenging. A focused physical examination and history are imperative, and many times the only required resource to establish the diagnosis. Movement disorders may be divided into hyperkinetic and hypokinetic, and this can be evaluated by performing a finger or foot tapping. Among the hyperkinetic disorders, you may classify them as jerky and non-jerky, while hypokinetic may vary in velocity, but in the end, are classified as a whole. The most common hyperkinetic disorder is essential tremor, while the most common hypokinetic one is Parkinson's disease.

Life Threatening Causes

Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.
