TY - CHAP M1 - Book, Section TI - Chapter 49. Systemic Illnesses that Cause Movement Disorders A1 - Colcher, Amy A1 - Hurtig, Howard I. A2 - Watts, Ray L. A2 - Standaert, David G. A2 - Obeso, Jose A. Y1 - 2012 N1 - T2 - Movement Disorders, 3e AB - Movement disorders often complicate systemic illnesses. They occur in conjunction with metabolic encephalopathy, infection, neoplasms, and disorders of the endocrine, immune, and hematological systems. Movement disorders associated with systemic illness run the gamut from an exaggerated physiological tremor to hemiballismus, and also include the akinetic-rigid syndromes. In some cases, the movement disorder is what causes the patient to consult a physician. The underlying disorder may or may not be known at the time the movement disorder becomes obvious. In some cases, the pathophysiology of the systemic disorder causing the movement disorder is known. In some cases, there is a structural lesion in the brain responsible for the neurological problem. In other cases, there is no clear explanation for the movement disorder in the context of the systemic disease.
