Withdrawal symptoms from lithium. Four case reports and a questionnaire study

Area of Science:

• Psychopharmacology
• Neuroscience

Background:

• Lithium is a mood stabilizer used in treating bipolar disorder.
• Understanding lithium's effects and withdrawal phenomena is crucial for patient management.

Observation:

• Case reports suggested heightened anxiety, irritability, and emotional lability upon lithium cessation.
• A survey of 110 former lithium clinic patients confirmed these temporary withdrawal symptoms in 19% of respondents.

Findings:

• Lithium withdrawal is associated with transient mood disturbances, including anxiety and irritability.
• The study also corroborated anecdotal evidence that lithium can dampen emotional responsiveness.

Implications:

• Phased lithium withdrawal is advised, especially when assessing continued clinical benefit.
• These findings necessitate a re-evaluation of current models explaining lithium's mechanism of action.
