Sleep linked to Parkinson's dementia

Researchers at Washington University School of Medicine in St. Louis have modeled Parkinson’s disease dementia in flies. Using genetically altered flies, researchers showed that loss of a single night’s sleep caused long-lasting disruption in the flies’ cognitive abilities. By feeding the flies high doses of the spice curcumin, a derivative of tumeric, this disruption in cognition could be blocked. Their results are reported in the journal Sleep and summarized here.
