Complaints about memory loss are very common in women in the menopausal transition period. The effectiveness of estrogen replacement therapy in cognitive improvement is controversial. Partial positive results were obtained in some studies with regard to memory improvement, so far no standard treatment considered effective in these cases. Effective pharmacological approaches to the treatment of memory loss associated with menopause are an unmet medical need. Cogmax® is a multivitamin and mineral supplement that contains numerous key elements for cognitive function, and may be a safe therapeutic option in these cases.

The multicenter, non-comparative (single-arm) phase IV clinical trial will be conducted with 80 female participants aged 45 to 60 years and menopausal memory loss complaint.

After 3 months of using multivitamin and mineral supplement, memory and attention will be reevaluated through specific questionnaire and the Stroop Test Victoria version.
