Abstract:

Statins have been reported to reduce the risk and be of benefit in the treatment of Alzheimer's disease (AD). Individuals enrolling in the randomized controlled trial testing two anti-inflammatory agents for primary prevention of AD (Alzheimer's Disease Anti-inflammatory Prevention Trial; ADAPT) were allowed the elective use of statins. Our objective was to assess whether statin use is associated with reduced risk of incident AD among ADAPT participants. In primary ADAPT study , participants were assessed annually for cholesterol levels and cognitive status. If impairment in cognition was noted, a dementia evaluation was performed. Onset of mild cognitive impairment (MCI) or AD was taken as the date of this evaluation. Time-to-onset was analyzed in six-month intervals following enrollment. Without knowledge of primary treatment assignment in ADAPT, participants were grouped by their self-reported use of lipid-lowering agents (LLA). In the current ancillary ADAPT study we found that elective statin use was associated with significantly reduced risk of incident AD after adjustment for age, gender, education and Apolipoprotein E (ApoE) genotype. The findings were similar when comparing all LLA use (statin and non-statin LLA) to non-LLA use. Cholesterol levels were lower among statin users compared with non-LLA users, but the MMSE scores were equivalent. The data suggest that statin therapy may be of benefit in reducing the risk of AD.

More about this publication?

• Current Alzheimer Research publishes peer-reviewed frontier review and research articles on all areas of Alzheimer's disease. This multidisciplinary journal will help in understanding the neurobiology, genetics, pathogenesis, and treatment strategies of Alzheimer's disease. The journal publishes objective reviews written by experts and leaders actively engaged in research using cellular, molecular, and animal models. The journal also covers original articles on recent research in fast emerging areas of molecular diagnostics, brain imaging, drug development and discovery, and clinical aspects of Alzheimer's disease. Manuscripts are encouraged that relate to the synergistic mechanism of Alzheimer's disease with other dementia and neurodegenerative disorders. Book reviews, meeting reports and letters-to-the-editor are also published. The journal is essential reading for researchers, educators and physicians with interest in age-related dementia and Alzheimer's disease. Current Alzheimer Research provides a comprehensive 'bird's-eye view' of the current state of Alzheimer's research for neuroscientists, clinicians, health science planners, granting, caregivers and families of this devastating disease.
