Rationale.Bacopa monnieri, popularly known as Brahmi, has been traditionally used in Ayurveda since ages for its memory enhancing properties. However, data on placebo-controlled trial ofBacopa monnierion intellectual sample is scarce. Hence this study was planned to evaluate the effect ofBacopa monnierion memory of medical students for six weeks.Objective. To evaluate the efficacy ofBacopa monnierion memory of medical students with six weeks’ administration.Method and Material. This was a randomized double blind placebo-controlled noncrossover, parallel trial. Sixty medical students of either gender from second year of medical school, third term, regular batch, were enrolled from Government Medical College, Nagpur, India. Baseline biochemical and memory tests were done. The participants were randomly divided in two groups to receive either 150 mg of standardized extract ofBacopa monnieri(Bacognize) or matching placebo twice daily for six weeks. All baseline investigations were repeated at the end of the trial. Students were followed up for 15 days after the intervention.Results. Statistically significant improvement was seen in the tests relating to the cognitive functions with use ofBacopa monnieri. Blood biochemistry also showed a significant increase in serum calcium levels (still within normal range).

And Performance

Abstract Objectives Curcumin (a flavonoid isolated from the spice turmeric) affects several processes involved in neurocognitive aging. We have previously reported that 4 weeks administration of a highly bioavailable curcumin extract (Longvida™) improved working memory and reduced fatigue and stress reactivity in older Australians. This follow-up study (ACTRN12616000484448) was aimed at determining if similar effects were evident following 12 weeks administration of the same extract. Methods A double-blind, placebo-controlled, parallel-groups trial was conducted. Eighty participants aged 50–80 years (mean = 68.1, SD 6.34) were randomised to receive administration of Longvida™ (400 mg daily containing 80 mg curcumin) or a matching placebo. Assessment took place at baseline then at 4 and 12 weeks. Outcomes included measures of cognitive performance focusing on memory processes relevant to hippocampal function. Participants also underwent neuroimaging and measures of mood, cardiovascular function and other blood biomarkers were collected. Results Compared with placebo, there were a number of improvements in the curcumin group. The curcumin group had significantly better working memory performance at 12 weeks, as measured by Serial Threes, Serial Sevens and performance on a virtual Morris Water Maze. Curcumin was also associated with better performance on a pattern separation task. Curcumin was also associated with significantly lower fatigue scores on the Profile of Mood States (POMS) at both 4 and 12 weeks, and of tension, anger, confusion and total mood disturbance at 4 weeks only. There were no group differences in biomarker levels. Conclusions These results confirm that Longvida™ improves aspects of mood and working memory in a healthy older cohort. The pattern of results is consistent with improvements in hippocampal function and may hold promise for alleviating cognitive decline in some populations.

Present Trial

Curcumin (a flavonoid isolated from turmeric) affects several processes involved in neurocognitive aging. We have previously reported that short term (4-weeks) administration of a highly bioavailable curcumin preparation (Longvida©) improved working memory and reduced fatigue and stress reactivity in a healthy older cohort. The present trial (ACTRN12616000484448) was a partial replication study, evaluating similar effects at 4 and 12-weeks Longvida© supplementation. A double-blind, placebo-controlled, parallel-groups trial was conducted. Eighty participants aged 50–80 years (mean = 68.1, SD = 6.34) were randomised to receive Longvida© (400 mg daily containing 80 mg curcumin) or a matching placebo. Assessment took place at baseline then following 4 and 12 weeks treatment. Outcome measures included cognitive performance, mood and biomarkers. Compared with placebo, curcumin was associated with several significant effects. These included better working memory performance at 12-weeks (Serial Threes, Serial Sevens and performance on a virtual Morris Water Maze), and lower fatigue scores on the Profile of Mood States (POMS) at both 4 and 12-weeks, and of tension, anger, confusion and total mood disturbance at 4-weeks only. The curcumin group had significantly elevated blood glucose. These results confirm that Longvida© improves aspects of mood and working memory in a healthy older cohort. The pattern of results is consistent with improvements in hippocampal function and may hold promise for alleviating cognitive decline in some populations.
