Lithium, Dementia Risk, and Renal Function: A Clinical Reappraisal
In this video, Dr Jonathan Meyer reviews evidence linking lithium and dementia risk, highlighting lithium’s unique neuroprotective effects in bipolar disorder.
Drawing on prospective comparative data, the discussion examines how long-term lithium exposure is associated with reduced dementia risk compared with valproate, with benefits accruing over time rather than immediately.
The video also addresses concerns about renal safety, reframing lithium neuroprotection within a modern physiological framework that emphasises glomerular filtration rate, systemic comorbidities, and confounding bias when attributing chronic kidney disease to lithium alone.

KEY TAKEAWAYS
- Bipolar disorder is associated with a substantially increased risk of dementia
- Long-term lithium exposure is linked to a significant reduction in future dementia risk
- Neuroprotective effects of lithium accrue over time rather than immediately
- Valproate and other anticonvulsants do not show similar dementia risk reduction
- Renal risk should be interpreted using GFR and comorbidity context rather than serum creatinine alone
