[Lithium distribution in organs after lithium poisoning]

Area of Science:

• Neuroscience
• Toxicology
• Pharmacology

Context:

• Lithium is a mood stabilizer used for bipolar disorder.
• Lithium intoxication can occur with therapeutic use or overdose.
• Co-existing conditions like influenza and diarrhea may affect lithium levels.

Purpose:

• To investigate lithium distribution in organs following fatal intoxication.
• To determine the extent of lithium accumulation in the brain and other tissues.
• To understand the pathological consequences of severe lithium poisoning.

Summary:

• Two cases of fatal lithium intoxication are presented in women with bipolar disorder.
• Despite medical treatment (NaCl infusions, hemodialysis), cerebral failure led to death.
• Significant lithium accumulation was observed in the brain, especially white matter, reaching toxic concentrations.

Impact:

• Highlights the potential neurotoxicity of lithium.
• Suggests that lipid-rich brain cells may preferentially accumulate lithium.
• Informs clinical management of lithium toxicity and patient monitoring.
