Bismuth subsalicylate preparations are over‐the‐counter products for gastrointestinal complaints. Bismuth toxicity causes delirium, psychosis, ataxia, myoclonus, and seizures and is reversible over several weeks or months, when bismuth intake is stopped. We report a 54‐year‐old man with a 6‐week history of progressive confusion and memory difficulty and a 2–3‐week history of involuntary movements and gait impairment. His encephalopathy was further characterized by marked multifocal myoclonic… Expand
Bismuth encephalopathy- a rare complication of long-standing use of bismuth subsalicylate
Although rare, bismuthEncephalopathy should be considered in patients presenting with subacute encephalopathy and myoclonus, even after a chronic exposure. Expand
Bismuth Toxicity: A Rare Cause of Neurologic Dysfunction
This case study highlights the fact that bismuth toxicity, while rare, should be considered in a patient with progressive neurological decline and reminds physicians of a severe consequence of a common, readily available medication. Expand

Delayed post-hypoxic leukoencephalopathy (DPHL) is a demyelinating syndrome characterized by acute onset of neuropsychiatric symptoms days to weeks following apparent recovery from coma after aExpand
Chapter 31 – Myoclonus
The diagnostic evaluation of myoclonus is complex and involves an extensive work-up including basic electrolytes, glucose, renal and hepatic function tests, paraneoplastic antibodies, drug and toxicology screens, thyroid antibody and function studies, neurophysiology testing, imaging, and tests for malabsorption disorders.

Site of Bismuth Absorption from Bismuth Subsalicylate
Poorly absorbed bismuth preparations may benefit a variety of chronic colonic conditions including ulcerative colitis. Bismuth-induced neurotoxicity is a potential complication of the chronic use ofExpand
Drug-Induced Myoclonus
Level II evidence is available to indicate that levodopa, cyclic antidepressants and bismuth salts can cause myoclonus, while there is less robust evidence to associate numerous other drugs with the induction of myOClonus. Expand

Is There a Role for Bismuth in Diarrhea Management?
The antisecretory, anti-inflammatory, and antibacterial properties of bismuth make it a suitable therapy for symptomatic treatment of diarrhea, and the limited range of adverse side effects makes it an appealing option for patients with numerous comorbidities. Expand

Permanent deterioration, affecting memory above all, tremor, marked insomnia, headache and disturbed gait are amongst the most durable complications, sometimes definitive, whilst in four cases osteo-arthropathy of the shoulders was associated with permanent invalidism. Expand
Epileptic phenomena in bismuth toxic encephalopathy.
A high cortical intracellular bismuth concentration induces a "cortical inhibition" which causes suppression of physiological electrical brain activity, the absence of EEG paroxysmal phenomena during myoclonic jerks, and explains the rarity of epileptic seizures. Expand
