    Area of Science:

    • Pharmacology
    • Neuroscience
    • Nephrology

    Background:

    • Current lithium treatment monitoring is empirical, focusing on compliance and toxicity.
    • Standard lithium dosing (once or thrice daily) results in pulsatile blood concentrations, limiting therapeutic efficacy.
    • Routine measurements fail to capture 24-hour concentration variability, hindering optimal use.

    Purpose of the Study:

    • To investigate the effects of rapid lithium administration on physiological and cognitive functions.
    • To explore a novel approach for quickly controlling manic episodes.
    • To gain a deeper understanding of lithium's mechanisms of action and its impact on cerebral functioning.

    Main Methods:

    • A pilot study involving rapid intravenous administration of lithium.
    • Monitoring plasma lithium concentrations over a few hours.
    • Assessing changes in kidney function and neuropsychological test performance.

    Main Results:

    • Plasma lithium concentration rapidly increased from 0 to 2 mmol/l within hours.
    • Observed significant changes in kidney function post-administration.
    • Detected prompt alterations in neuropsychological test results.

    Conclusions:

    • Rapid lithium dosing can induce rapid changes in physiological and neuropsychological parameters.
    • This approach suggests potential for swift control of mania.
    • Opens new avenues for studying lithium's mechanism of action and cerebral effects.
