Deskripsi

Paroxysmal dysarthria and ataxia (PDA) is a rare syndrome characterized by brief, stereotyped episodes of slurred speech, clumsiness with extremities, or vertigo. It is usually observed in young patients suffering from multiple sclerosis with numerous lesions. PDA is challenging to identify in those presenting with atypical patterns. Here, a non-ataxic variant of PDA in an otherwise neurologically healthy elderly man is presented who had a single midbrain lesion. A broad diagnostic workup illustrates the challenges of identifying PDA. Teaching points emphasize the significance of the midbrain lesion and response to anti-epileptic medication.
