Methamphetamine Use Impairs Learning
UCI scientists have demonstrated in rats that methamphetamine use can impair their ability to learn. This result has been observed in humans but only a few times replicated in an animal model. The UCI finding adds to growing evidence that methamphetamine, in addition to causing brain damage in humans and animals, creates behavioral impairments in rats that may reflect the cognitive dysfunction observed in humans. It also could help scientists develop new treatments for people suffering from the side effects of methamphetamine.

Blood Test Holds Promise for Alzheimers Disease Diagnosis
UC Irvine scientists have found that gene expression patterns in white blood cells taken from patients with Alzheimers disease differ significantly from patterns in healthy people of the same age and sex. The difference was large enough, the researchers say, that it was possible by looking only at the blood samples to tell which ones belong to the Alzheimers patients. The finding could provide the basis for a simple and reliable blood test to diagnose Alzheimers disease.
