Brief summary

In this randomised, double-blind, placebo-controlled study, 80 adults with mild cognitive impairment will be randomly assigned to receive capsules containing either an Oroxylum indicum extract (1000 mg a day) or placebo for 12 weeks. A computer-based assessment and several validated clinician-administered and self-report measures (to be completed at various time points throughout the study) will be administered to assess change in cognitive performance and quality of life. We will also examine changes in blood concentrations of brain-derived neurotrophic factor (BDNF).

Interventions

Condition 1: Placebo capsules (1 capsule taken orally, twice daily after food at breakfast and dinner times for 12 weeks) Condition 2: Oroxylum indicum extract (Sabroxy) (1 capsule taken orally, twice daily after food at breakfast and dinner times, delivering 1000mg a day, for 12 weeks) Adherence to capsule intake will be monitored through capsule return and count.
