Turmeric-Based Drug Effective On Alzheimer Flies

Curcumin, a substance extracted from turmeric, prolongs life and enhances activity of fruit flies with a nervous disorder similar to Alzheimers, according to new research. The study conducted at Linköping University, indicates that it is the initial stages of fibril formation and fragments of the amyloid fibrils that are most toxic to neurons.

However, the scientists saw no decrease of amyloid in the brain or eyes. Curcumin did not dissolve the amyloid plaque; on the contrary it accelerated the formation of fibres by reducing the amount of their precursor forms, known as oligomers.

"The results confirm our belief that it is the oligomers that are most harmful to the nerve cells," says Professor Per Hammarstrom, who led the study.
