RT Journal Article SR Electronic T1 Prevention of Alzheimer disease. Encouraging evidence. JF Canadian Family Physician JO Can Fam Physician FD The College of Family Physicians of Canada SP 200 OP 207 VO 52 IS 2 A1 Monica Zavaloni Scalco A1 Robert van Reekum YR 2006 UL http://www.cfp.ca/content/52/2/200.abstract AB OBJECTIVE To review the evidence regarding prevention of Alzheimer disease (AD) in order to highlight the role of family medicine. QUALITY OF EVIDENCE Most of the evidence relating to prevention of AD is derived from observational (cross-sectional, case-control, or longitudinal) studies. Evidence from randomized controlled trials (RCTs) is available only for blood pressure control and for hormone replacement therapy for menopausal women. MAIN MESSAGE Many preventive approaches to AD have been identified, but no RCTs support their efficacy. Evidence from RCTs supports the effectiveness of blood pressure control in reducing incidence of AD, but demonstrates that postmenopausal women's use of estrogen is ineffective in reducing it. Observational studies suggest that some preventive approaches, such as healthy lifestyle, ongoing education, regular physical activity, and cholesterol control, play a role in prevention of AD. These approaches can and should be used for every patient because they carry no significant risk. Currently, no effective pharmacologic interventions have been researched enough to support their use in prevention of AD. CONCLUSION Health professionals should educate patients, especially patients at higher risk of AD, about preventive strategies and potentially modifiable risk factors.
