          Body mass index in midlife and late-life as a risk factor for dementia: a meta-analysis of prospective studies.

          The relationship between body mass index (BMI) (in midlife and late-life) and dementia was investigated in meta-analyses of 16 articles reporting on 15 prospective studies. Follow-ups ranged from 3.2 to 36.0 years. Meta-analyses were conducted on samples including 25 624 participants evaluated for Alzheimer's disease (AD), 15 435 participants evaluated for vascular dementia (VaD) and 30 470 followed for any type of dementia (Any Dementia). Low BMI in midlife was associated with 1.96 [95% confidence interval (CI): 1.32, 2.92] times the risk of developing AD. The pooled relative risks for AD, VaD and Any Dementia for overweight BMI in midlife compared with normal BMI were 1.35 (95% CI:1.19, 1.54), 1.33 (95% CI: 1.02, 1.75) and 1.26 (95% CI: 1.10, 1.44), respectively. The pooled relative risks of AD and Any Dementia for obese BMI in midlife compared to normal BMI were 2.04 (95% CI: 1.59, 2.62) and 1.64 (95% CI: 1.34, 2.00), respectively. Continuous BMI in late-life was not associated with dementia. Small numbers of studies included in pooled analyses reduce generalizability of findings, and emphasize the need for publication of additional findings. We conclude that underweight, overweight and obesity in midlife increase dementia risk. Further research evaluating late-life BMI and dementia is required. © 2011 The Authors. obesity reviews © 2011 International Association for the Study of Obesity.

            15-year longitudinal study of blood pressure and dementia.

            Vascular causes of dementia may be more common than supposed. Vascular factors may also have a role in late-onset Alzheimer's disease, but the role of hypertension in the development of dementia is unclear. As part of the Longitudinal Population Study of 70-year-olds in Göteborg, Sweden, we analysed the relation between blood pressure and the development of dementia in the age intervals 70-75, 75-79, and 79-85 years in those non-demented at age 70 (n = 382). The sample was followed up for 15 years and examined repeatedly with a comprehensive investigation, including a psychiatric and physical examination. a Participants who developed dementia at age 79-85 had higher systolic blood pressure at age 70 (mean 178 vs 164 mm Hg, p = 0.034) and higher diastolic blood pressure at ages 70 (101 vs 92, p = 0.004) and 75 (97 vs 90, p = 0.022) than those who did not develop dementia. For subtypes of dementia, higher diastolic blood pressure was recorded at age 70 (101, p = 0.019) for those developing Alzheimer's disease and at age 75 (101, p = 0.015) for those developing vascular dementia than for those who did not develop dementia. Participants with white-matter lesions on computed tomography at age 85 had higher blood pressure at age 70 than those without such lesions. Blood pressure declined in the years before dementia onset and was then similar to or lower than that in non-demented individuals. Previously increased blood pressure may increase the risk for dementia by inducing small-vessel disease and white-matter lesions. To what extent the decline in blood pressure before dementia onset is a consequence or a cause of the brain disease remains to be elucidated.

              Working Memory and Executive Function Decline across Normal Aging, Mild Cognitive Impairment, and Alzheimer's Disease

              Alzheimer's disease (AD) is a progressive neurodegenerative disease marked by deficits in episodic memory, working memory (WM), and executive function. Examples of executive dysfunction in AD include poor selective and divided attention, failed inhibition of interfering stimuli, and poor manipulation skills. Although episodic deficits during disease progression have been widely studied and are the benchmark of a probable AD diagnosis, more recent research has investigated WM and executive function decline during mild cognitive impairment (MCI), also referred to as the preclinical stage of AD. MCI is a critical period during which cognitive restructuring and neuroplasticity such as compensation still occur; therefore, cognitive therapies could have a beneficial effect on decreasing the likelihood of AD progression during MCI. Monitoring performance on working memory and executive function tasks to track cognitive function may signal progression from normal cognition to MCI to AD. The present review tracks WM decline through normal aging, MCI, and AD to highlight the behavioral and neurological differences that distinguish these three stages in an effort to guide future research on MCI diagnosis, cognitive therapy, and AD prevention.
