After analyzing the results, they found that those who had curcumin saw “significant improvements in their memory and attention abilities,” compared to those who had not had it, the report said. In fact, those who had the curcumin performed 28 percent better on the memory tests after 18 months.
While they are unsure why curcumin has this effect, they think "it may be due to its ability to reduce brain inflammation, which has been linked to both Alzheimer's disease and major depression," co-author Gary Small, said in a statement. "These results suggest that taking this relatively safe form of curcumin could provide meaningful cognitive benefits over the years."
Analysts also discovered that those who had curcumin reported being in a better mood. That's why scientists want to further their investigations to find out if the chemical can help people with mild depression.
They also want to administer a larger study for people with varying ages and genetic makeup.
