Lithium neurotoxicity with electroencephalogram changes

Abstract

Lithium is a medication with a variety of medical usage for various diseases including bipolar mood disorder. As the therapeutic window of lithium is narrow, its usage is commonly associated with toxicity. Lithium toxicity affects multiple systems especially the central nervous system, leading to neuropsychiatric complications. Haemodialysis is an effective method for lithium removal especially in severe lithium toxicity such as neurotoxicity with electroencephalogram changes. We describe a case of lithium neurotoxicity with electroencephalographic abnormalities which was reversed following haemodialysis.
