RT Journal Article SR Electronic T1 Does this patient have Alzheimer disease? Diagnosing and treating dementia JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 762 OP 776 VO 70 IS 9 A1 Messinger-Rapport, Barbara J. YR 2003 UL http://www.ccjm.org/content/70/9/762.abstract AB Alzheimer disease follows a pattern of gradual cognitive, behavioral, and functional decline. Other causes of dementia have overlapping presentations, but with important differences. Most patients with mild to moderate dementia should be treated with cholinesterase inhibitors to temporarily stabilize symptoms and delay clinically important end points. Memantine, an N-methyl-D-aspartate antagonist, may soon be available to treat moderate to severe dementia.
