    Area of Science:

    • Neuroscience
    • Psychopharmacology

    Background:

    • Sodium valproate is a widely used antiepileptic drug.
    • Understanding its cognitive side effects is crucial for patient management.

    Purpose of the Study:

    • To investigate the effects of sodium valproate on cognitive function and mood.
    • To compare these effects with placebo in healthy male volunteers.

    Main Methods:

    • A double-blind, placebo-controlled, cross-over study design was employed.
    • Ten healthy male volunteers received escalating doses of sodium valproate (up to 1 g/day) or placebo for two weeks each.
    • Psychological testing and mood assessments were conducted at baseline and after each treatment period.

    Main Results:

    • Sodium valproate administration resulted in statistically significant impairments in certain psychological test performances compared to placebo.
    • Mood alterations were also observed, though less pronounced than cognitive effects.

    Conclusions:

    • Sodium valproate may negatively impact cognitive functions in individuals, even those without epilepsy.
    • These findings warrant consideration of neurocognitive side effects in clinical practice and further research comparing with other anticonvulsants like phenytoin.
