COVID-19 is an emerging, rapidly evolving situation. We report here on a patient presenting progressive external ophthalmoplegia followed by pseudo-orthostatic tremor and parkinsonism. Tremor during standing usually has a low frequency (range, 4-6 Hz), similar to PD rest tremor frequency, and is improved by levodopa.
