In the elderly, the response to stressful procedures like surgery can lead to some post-operative effects on mood and perception. These effects can hamper the recovery process.

A new study published in the September 2008 issue of the Canadian Medical Association Journal from Ontario’s Institute for Clinical Evaluative Sciences (ICES) found the use of stains – which include Crestor, Lipitor, Pravachol and Zocor was associated with 28% increase risk of post operative delirium among elderly patients.
