Studying nearly 600 patients for 15 years, researchers found that using several standardized tests to develop a progression rate prediction was successful in forecasting the speed at which Alzheimer's eventually developed.

From Georgia - Regular exercise may reduce anxiety, according to a report publisehd in the Archives of Internal Medicine. Researchers conducted a meta-anaylsis of 40 clinical trials covering almost 3,000 patients, finding that regular exercise resulted in a 20% reduction in anxiety symptoms.

And finally, from San Diego- According to a report presented at the annual meeting of the American Association of the Advancement of Science, napping may refresh the mind and help it learn better. Researchers had nearly 40 healthy adults undergo one learning task at noon and then another one at 6 pm, randomizing half to a 90 minute nap at 2 pm and the other half to stay awake during the day. Results showed that people who napped learned significantly more in the later session than those who stayed awake.
