Curcumin: A Spice Against Alzheimer's

Author: Melania Tesio

Curcumin, a polyphenol derived from the South Asian spice turmeric, protects nerve cells from death. This compound may, thus, be beneficial in patients suffering from Alzheimer’s, a neurodegenerative disease. The delivery of curcumin to the brain, however, is challenging as this polyphenol does not cross the blood–brain barrier, a protective barrier surrounding the central nervous system.

To overcome this problem, Kailash Chand Gupta, CSIR – Indian Institute of Toxicology Research, Lucknow, India, and co-workers encapsulated curcumin inside biodegradable poly(lactic-co-glycolitic acid) nanoparticles (Cur-PLGA-NPs). Once administered to rats, the new nanoparticles easily crossed the blood–brain barrier, thereby accumulating in the rats’ brains. In addition, thanks to their ability to release curcumin in a slow and sustained manner, Cur-PLGA-NPs stimulated the generation of new neurons, ultimately improving cognitive functions and memory in a rat model of Alzheimer’s disease.
