Parkinsonism in alcohol withdrawal: A follow‐up study

Transient parkinsonism associated with alcohol intake and withdrawal has previously been described. We followed‐up three patients with acute alcohol withdrawal‐induced parkinsonism 9–11 years after their initial presentation. None showed any evidence of parkinsonism at follow‐up. This suggests that withdrawal‐induced parkinsonism is caused by a completely reversible abnormality in nigrostriatal dopamine transmission, which is unaccompanied by underlying nigral degeneration, as we had previously hypothesized.
