Coffee drinkers may have another reason to pour that extra cup. When aged mice bred to develop symptoms of Alzheimer's disease were given caffeine – the equivalent of five cups of coffee a day – their memory impairment was reversed, report University of South Florida researchers at the Florida Alzheimer's Disease Research Center.

Mild memory impairment may be associated with central auditory processing dysfunction, or difficulty hearing in complex situations with competing noise, such as hearing a single conversation amid several other conversations, according to a report in the July issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.

A mind-altering mutation in mice results in an enhanced long-term memory, researchers report in the April 6, 2007 issue of the journal Cell, published by Cell Press. These findings point to a potential target for the development of a drug to treat memory loss, according to the researchers.
