The German study suggests a compound found in turmeric could encourage the growth of nerve cells thought to be part of the brain’s repair kit. Scientists say this work, based in rats, may pave the way for future drugs for strokes and Alzheimer’s disease. But they say more trials are needed to see whether this applies to humans.
Researchers from the Institute of Neuroscience and Medicine in Julich, Germany, studied the effects of aromatic-turmerone – a compound found naturally in turmeric. Rats were injected with the compound and their brains were then scanned. Particular parts of the brain, known to be involved in nerve cell growth, were seen to be more active after the aromatic-turmerone infusion.
Scientists say the compound may encourage a proliferation of brain cells. In a separate part of the trial, researchers bathed rodent neural stem cells (NSCs) in different concentrations of aromatic-tumerone extract. NSCs have the ability to transform into any type of brain cell and scientists suggest they could have a role in repair after damage or disease.
