Ataxia can be caused by various reasons such as:
- Damage to the central nervous system e.g. stroke or brain tumour.
- Vitamin B12 deficiency
- Exogenous substances such as ethanol. Some prescription drugs may result in ataxia as a side effect such as antiepileptic drugs
- Peripheral neuropathies may result in an isolated sensory ataxia.
- Arnold-Chiai malformations
- Hereditary ataxias
