Cerebellar ataxia, characterised by an impaired ability to maintain balance and stability even with open eyes during the Romberg test, is attributed to a lesion in the cerebellum. This neurodegenerative condition can manifest in varying degrees of severity and not only affects stability and coordination of movements but also affect speech articulation, writing, and control of eye movements. To further assess this condition, the index-nose test can be conducted. In this test, the patient extends their arm while standing and attempts to touch the tip of their nose with their index finger, where Ataxia will complicate this seemingly simple action. If there is suspicion of cerebellar ataxia, it is best to consult a neurological specialist to establish a definitive diagnosis and develop a comprehensive therapeutic and rehabilitation plan.
