Bismuth Toxicity as a Cause of Parkinsonism

Melissa Stockton-Brown

Parkinsonism” or a “Parkinsonian appearance” describes a cluster of neurologic signs and symptoms related to movement, such as rigidity, tremor, and abnormal gait. The list of causes is wide, the most common and memorable of which are neurodegenerative disorders (such as parkinson’s disease, corticobasal degeneration, multisystem atrophy, and lewy body dementia). There are however iatrogenic causes (such as the use of antipsychotic medication) and, more rarely, toxic encephalopathy. Here we discuss bismuth salicylate, as found in over-the-counter medications, as a cause of parkinsonism in a patient with chronic, unmanaged gastrointestinal symptoms.
