Screening for dementia in primary care: a summary of the evidence for the U.S. Preventive Services Task Force.

BACKGROUND: Dementia is a large and growing problem but is often not diagnosed in its earlier stages. Screening and earlier treatment could reduce the burden of suffering of this syndrome. PURPOSE: To review the evidence of benefits and harms of screening for and earlier treatment of dementia. DATA SOURCES: MEDLINE, PsycINFO, EMBASE, the Cochrane Library, experts, and bibliographies of reviews. STUDY SELECTION: The authors developed eight key questions representing a logical chain between screening and improved health outcomes, along with eligibility criteria for admissible evidence for each question. Admissible evidence was obtained by searching the data sources. DATA EXTRACTION: Two reviewers abstracted relevant information using standardized abstraction forms and graded article quality according to U.S. Preventive Services Task Force criteria. DATA SYNTHESIS: No randomized, controlled trial of screening for dementia has been completed. Brief screening tools can detect some persons with early dementia (positive predictive value < or =50%). Six to 12 months of treatment with cholinesterase inhibitors modestly slows the decline of cognitive and global clinical change scores in some patients with mild to moderate Alzheimer disease. Function is minimally affected, and fewer than 20% of patients stop taking cholinesterase inhibitors because of side effects. Only limited evidence indicates that any other pharmacologic or nonpharmacologic intervention slows decline in persons with early dementia. Although intensive multicomponent caregiver interventions may delay nursing home placement of patients who have caregivers, the relevance of this finding for persons who do not yet have caregivers is uncertain. Other potential benefits and harms of screening have not been studied. CONCLUSIONS: Screening tests can detect undiagnosed dementia. In persons with mild to moderate clinically detected Alzheimer disease, cholinesterase inhibitors are somewhat effective in slowing cognitive decline. The effect of cholinesterase inhibitors or other treatments on persons with dementia detected by screening is uncertain.

Screening for type 2 diabetes mellitus in adults: recommendations and rationale.

This statement summarizes the current U.S. Preventive Services Task Force (USPSTF) recommendations on screening for type 2 diabetes in adults and updates the 1996 recommendations on this topic. The complete USPSTF recommendation and rationale statement on this topic, which includes a brief review of the supporting evidence, is available through the USPSTF Web site ( http://www.preventiveservices.ahrq.gov ) and the National Guideline Clearinghouse ( http://www.guideline.gov ) and in print through the Agency for Healthcare Research and Quality (AHRQ) Publications Clearinghouse (call 800-358-9295 or e-mail mailto:ahrqpubs@ahrq.gov ). The complete information on which this statement is based, including evidence tables and references, is available in the accompanying article in this issue and in the summary of the evidence and systematic evidence review on this topic on the Web sites already mentioned. The summary of the evidence is also available in print through the AHRQ Publications Clearinghouse.

Postmenopausal hormone replacement therapy for primary prevention of chronic conditions: recommendations and rationale.

This statement summarizes the U.S. Preventive Services Task Force (USPSTF) recommendations for use of hormone replacement therapy for the primary prevention of chronic conditions in postmenopausal women and updates the 1996 USPSTF recommendations on this topic. The complete information on which this statement is based, including evidence tables and references, is available through the USPSTF Web site (http://www.preventiveservices.ahrq.gov) and through the National Guideline Clearinghouse (http://www.guideline.gov) The USPSTF reviewed the evidence on the use of postmenopausal hormone replacement therapy and the following outcomes: cardiovascular disease, including CHD and stroke; osteoporosis and fractures; thromboembolism; dementia and cognitive function; breast, colon, ovarian, and endometrial cancer; and cholecystitis. The USPSTF also reviewed evidence of the effects of hormone replacement therapy on phytoestrogens and osteoporosis and cardiovascular disease. The use of hormone replacement therapy for relieving active symptoms of menopause, such as hot flashes, urogenital symptoms, and mood and sleep disturbances, among others, is outside the scope of these USPSTF recommendations, and literature on this topic was not reviewed. Sources for estimates of benefits and harms cited in this Recommendation statement are described in the summary of the evidence available from the Agency for Healthcare Research and Quality.
