Summary
Lithium sulphate intake in healthy males impaired mood and cognitive performance, evidenced by increased errors and a lower flicker fusion threshold. Further research is needed to clarify observed electroencephalogram (EEG) changes.
Area of Science:
- Neuroscience
- Psychopharmacology
Background:
- Lithium is widely used for bipolar disorder treatment.
- Its effects on healthy individuals require further investigation.
Purpose of the Study:
- To evaluate the effects of lithium sulphate on cognitive performance, mood, and electroencephalogram (EEG) in healthy males.
Main Methods:
- Controlled double-blind trial with 24 healthy male volunteers.
- Treatment with lithium sulphate (24-36 mval/d) or placebo for one and two weeks.
- Assessment using quantitative pharmaco-EEG, psychological performance tests (e.g., pursuit rotor), and mood scales.
Main Results:
- Lithium sulphate intake led to increased mistake duration on the pursuit rotor test (MLS).
- A decreased flicker fusion threshold was observed in the lithium group compared to placebo.
- Impairment in mood was reported by participants receiving lithium.
- Observed EEG changes included decreased 7-9 cps and increased 20-50 cps activity.
Conclusions:
- Lithium sulphate administration affects cognitive functions and mood in healthy males.
- Observed EEG alterations warrant further investigation to understand their clinical significance.
