Complex movement disorders in ataxia with oculomotor apraxia type 1. Segment one shows an ataxic gait pattern with generalized dystonia (affecting predominantly the trunk and cervical region), myoclonic jerks and choreoathetotic movements in her hands. Segment two shows oculomotor apraxia with hypometric saccades and cervical dystonia with choreoathetotic movements in her hands. Segment three shows cervical, upper and lower limb dystonic postures with choreoathetotic movements in her upper-limbs and dysmetria in the finger-to-nose maneuver.
