Knowra Cerebellar ataxia Cerebellar ataxia Cerebellar ataxia is impaired coordination caused by damage or dysfunction of the cerebellum or its connections. It can disrupt balance, gait, speech, and precise movements.
Cerebellum : A brain structure that coordinates movement, balance, posture, and motor learning. Its dysfunction disrupts the timing and accuracy of coordinated movement.
Gait ataxia : Unsteady, poorly coordinated walking caused by impaired balance or movement control. A broad-based, irregular gait is a common manifestation of cerebellar dysfunction.
Spinocerebellar ataxia : A group of inherited disorders that progressively damage the cerebellum and related pathways. These genetic disorders are major causes of progressive cerebellar ataxia.
Sensory ataxia : Incoordination caused by loss of proprioceptive input from peripheral nerves or sensory pathways. It can resemble cerebellar ataxia but often worsens when visual guidance is removed.
Physical therapy : Rehabilitation using movement, exercise, and training to improve physical function. Balance and coordination training can support mobility despite persistent cerebellar impairment.
Dysmetria : A movement error in which a person overshoots or undershoots a target. It is a characteristic sign of impaired cerebellar control.
Ataxic dysarthria : A speech disorder marked by irregular timing, stress, and articulation. Cerebellar impairment can disrupt the coordination of speech muscles.
Friedreich ataxia : An inherited neurodegenerative disorder caused by reduced frataxin, often affecting coordination and the heart. It can cause ataxia through degeneration of sensory pathways and cerebellar connections.
Vestibular ataxia : Imbalance and unsteadiness caused by dysfunction of the vestibular system. Vertigo and vestibular signs distinguish this source of imbalance from cerebellar dysfunction.
Occupational therapy : Therapeutic support that helps people perform daily activities and adapt their environments. Task strategies and adaptations can reduce the practical effects of incoordination.
