Coordination Disorders
Introduction
Coordination disorders often result from malfunction of the cerebellum, the part of the brain that coordinates voluntary movements and controls balance. The cerebellum malfunctions, causing loss of coordination. Often, people cannot control their arms and legs, making them take wide, unsteady steps when they walk. Doctors base the diagnosis on symptoms, family history, magnetic resonance imaging of the brain, and often genetic testing. The cause is corrected if possible, and if it cannot be, treatment focuses on relieving symptoms. (See also Overview of Movement Disorders .) The cerebellum is the part of the brain most involved in coordinating sequences of movements. It also controls balance and posture. Anything that damages the cerebellum can lead to loss of coordination (ataxia). However, Many other disorders can also cause loss of coordination.
