In the article, “Treatment of Alzheimer Disease” (June 15, 2011, page 1403), the first clinical recommendation in the Strength of Recommendation Taxonomy (SORT) table (page 1404) was not as complete or balanced as it should have been. The recommendation, “Acetylcholinesterase inhibitors should be considered first-line therapy for patients with mild to moderate Alzheimer disease,” should have mentioned the adverse effects associated with this drug class. The revised recommendation should read: “Acetylcholinesterase inhibitors are modestly effective in patients with mild to moderate Alzheimer disease, although limited by their adverse effects.” The article has been corrected online.
