Gabapentin has been accepted worldwide as a novel antiepileptic drug with a favourable tolerability profile. However, movement disorders have been reported previously as rare side-effects in individual patients. We report on two patients who developed isolated severe ataxia under low-dose gabapentin which resolved abruptly after discontinuation of the drug. This side-effect probably resembled a rare idiosyncratic adverse reaction. We propose the gabapentin-specific neuronal binding site which has a high density in the cerebellum as a possible mechanism of action and suggest that the initiation of gabapentin requires caution if pre-existing cerebellar function impairment is evident.
