Permanent neurological sequelae despite haemodialysis for lithium intoxication
British Medical Journal
|December 30, 1972
Summary
Prolonged lithium toxicity can cause permanent neurological damage, even after treatment. Hemodialysis is the preferred treatment for lithium toxicity, though peritoneal dialysis is an alternative when hemodialysis is unavailable.
Area of Science:
- Nephrology
- Neuroscience
- Toxicology
Background:
- Lithium is a common treatment for bipolar disorder.
- Lithium toxicity can occur with therapeutic use or overdose.
- Neurological complications are a known risk of lithium toxicity.
Purpose of the Study:
- To report cases of lithium toxicity.
- To evaluate the effectiveness of dialysis in treating lithium toxicity.
- To highlight the long-term consequences of prolonged lithium exposure.
Main Methods:
- Case report of three patients with lithium toxicity.
- Analysis of lithium levels during dialysis.
- Comparison of hemodialysis and peritoneal dialysis for lithium removal.
Main Results:
- Two patients with prolonged exposure survived but had permanent basal ganglia and cerebellar damage.
- Hemodialysis effectively lowered lithium levels.
- Peritoneal dialysis also lowered lithium levels, but at a slower rate than hemodialysis.
Conclusions:
- Prolonged lithium toxicity can lead to irreversible neurological deficits.
- Hemodialysis is the treatment of choice for lithium toxicity.
- Peritoneal dialysis is a viable alternative when hemodialysis is not accessible.
