Ataxia Dubai | Neurological Disorders Dubai UAE

ATAXIA:

Ataxia is incoordination of the muscles during a voluntary movement or that sustain a

voluntary posture. Disturbance of coordination is caused by a dysfunction in the cerebellum or

its connections.Damage to the cerebellar hemisphere causes a tendency to veer

in the direction of the affected hemisphere with dystaxia and hypotonia of the ipsilateral limb.

Abnormality of the cerebellar vermis results in head bobbing (titubation), gait and truncal ataxia

and nystagmus. Involvement of the sensory pathways in the spinal cord and peripheral nerve

results in a wide based gait and inability to maintain a standing posture with the eyes closed

(Romberg’s sign). Based on duration and progression, ataxias can be classified into acute and

chronic ataxias.
