PY - 2016 T2 - Clinical Neurology and Neuroanatomy: A Localization-Based Approach AB - In most realms of neurologic disease, localization is the first step toward differential diagnosis. In assessing movement disorders, however, the first step is to accurately characterize the type of abnormal movement(s) present, each of which has its own differential diagnosis. Movement disorders are broadly classified as either hyperkinetic (increased movement: tremor, chorea, myoclonus, dystonia, tics) or hypokinetic (decreased movement: bradykinesia as is seen in parkinsonism) (Table 23–1).
