Vascular factors and multiple measures of early brain health: CARDIA brain MRI study.
<h4>Objective</h4>To identify early changes in brain structure and function that are associated with cardiovascular risk factors (CVRF).<h4>Design</h4>Cross-sectional brain Magnetic Resonance I (MRI) study.<h4>Setting</h4>Community based cohort in three U.S. sites...

Total intracranial volume is TBV plus cerebral spinal fluid (TICV). A Global Cognitive Function (GCF) score was derived from tests of speed, memory and executive function.<h4>Results</h4>Adjusting for TICV and demographic factors, current smoking was significantly associated with lower GM-CBF and TBV, and more AWM (all <0.05); SA with lower GM-CBF, WM-FA and TBV (p=0.01); increasing BMI with decreasing GM-CBF (p<0003); hypertension with lower GM-CBF, WM-FA, and TBV and higher AWM (all <0.05); and diabetes with lower TBV (p=0.007). The GCS was lower as TBV decreased, AWM increased, and WM-FA (all p<0.01).<h4>Conclusion</h4>In middle age adults, CVRF are associated with brain health, reflected in MRI measures of structure and perfusion, and cognitive functioning.
