From Blood Pressure To Physical Disability: The Role Of Cognition, Merrill F. Elias, Gregory A. Dore, Adam Davey, Michael A. Robbins, Penelope K. Elias Apr 2010

From Blood Pressure To Physical Disability: The Role Of Cognition, Merrill F. Elias, Gregory A. Dore, Adam Davey, Michael A. Robbins, Penelope K. Elias

Maine-Syracuse Longitudinal Papers

We examined the hypothesis that lowered cognitive performance plays a role in the relation between elevated blood pressure and physical disability in performing basic physical tasks. A community-based sample (N = 1025) free from stroke and dementia (mean age: 61.1 years; SD: 13.0 years; 59.8% women) was used. Using path analysis, systolic and diastolic blood pressures (predictor variable) measured over multiple longitudinal examinations were averaged and related to multiple measures of cognition (intermediate variable) and physical ability (PA; outcome variable) measured at wave 6 of the Maine-Syracuse Study. PA was indexed by time required to execute standing, walking, and turning …

Arterial Pulse Wave Velocity And Cognition With Advancing Age, Merrill F. Elias, Michael A. Robbins, Marc M. Budge, Walter P. Abhayaratna, Gregory A. Dore, Penelope K. Elias

Maine-Syracuse Longitudinal Papers

We hypothesized that carotid-femoral pulse wave velocity (PWV), a marker of arterial stiffness, interacts with age such that the magnitude of associations between PWV and cognitive performance are greater with increasing age and that this interaction is observed despite adjustments for demographic variables, mean arterial pressure, and cardiovascular risk factors. PWV was estimated using applanation tonometry in 409 dementia- and stroke-free participants of the Maine-Syracuse Longitudinal Study (24 to 92 years of age; 62.3% women). Using linear regression analyses in a cross-sectional design, associations between PWV and age and the interaction of PWV and age were examined in relation to …

Maine-Syracuse Longitudinal Papers

Background. Non-dialysis-dependent chronic kidney dis- ease (CKD) is related to cognitive impairment. Previous studies have not explored the extent of impairment across multiple cognitive domains. We examined the range of specific cognitive abilities affected by CKD and whether the associations of CKD with cognition were eliminated by statistical control for cardiovascular disease correlates of CKD. Methods. We performed a community-based cross-sectional study with 923 individuals free from dementia and end-stage renal disease. Two groups were defined based on estimated glomerular filtration rate (eGFR): eGFR/min/1.73 m2 versus eGFR≥60 mL/min/1.73 m2. Out- come measures were scores from multiple clinical tests of specific …


Homocysteine, Folate, And Vitamins B6 And B12 Blood Levels In Relation To Cognitive Performance: The Maine-Syracuse Study, Merrill F. Elias, Michael A. Robbins, Marc M. Budge, Penelope K. Elias, Suzanne L. Brennan, Carole Johnston, Zsuzsanna Nagy, Christopher J. Bates Jan 2006

Maine-Syracuse Longitudinal Papers

Objective: Our objective was to examine associations among plasma homocysteine concentrations (tHcy), the tHcy-cofactors (folate, vitamins B6 and B12), and multiple domains of cognitive performance, with statistical adjustment for possible confounds, including cardiovascular disease risk factors (CVD-RF) and cardiovascular disease (CVD). Methods: Subjects were 812 partici- pants (58% women) of the Maine-Syracuse study who were free of dementia and stroke. Employing a cross-sectional design and multiple regression analyses, fasting concentrations of tHcy and its vitamin cofactors (folate, B6, and B12) were related to multiple domains of cognitive performance. Results: With adjustment for age, education, gender, ethnicity, and the …
