Physiologic changes during normal pregnancy and delivery.
The major adaptations of the maternal cardiovascular system that progress throughout gestation may unmask previously unrecognized heart disease and result in significant morbidity and mortality. Most of these changes are almost fully reversed in the weeks and months after delivery. Hemodynamic changes during pregnancy include increased blood volume, cardiac output (CO), and maternal heart rate;...
متن کاملMotor and cognitive changes in normal aging
In a recent study, Cid-Fernandez et al. (2014) tested attentional performance in 3 age groups: young (21–29 years old), middle-aged (51–64 years old), and older adults (65–84 years old). The task used in this study involved presenting both visual and auditory cues to the participants, and they were required to pay attention to the visual cues while ignoring the auditory cues (for task details, ...
متن کاملCellular and Molecular Changes during Normal Aging
This chapter provides developmental neurobiologists with an overview of cellular and molecular changes that occur in the nervous system during aging, describes the current state of understanding of how aging impacts developmental processes operative in the adult nervous system, and considers how developmental mechanisms may contribute to the pathogenesis of neurodegenerative disorders such as A...
متن کاملDendritic spine changes associated with normal aging.
Given the rapid rate of population aging and the increased incidence of cognitive decline and neurodegenerative diseases with advanced age, it is important to ascertain the determinants that result in cognitive impairment. It is also important to note that much of the aged population exhibit 'successful' cognitive aging, in which cognitive impairment is minimal. One main goal of normal aging st...
متن کاملRegional and global changes in cerebral diffusion with normal aging.
BACKGROUND AND PURPOSE We used quantitative diffusion MR imaging to investigate the microstructural changes that occur in white matter during normal aging in order to identify regional changes in anisotropy and to quantify global microstructural changes by use of whole-brain diffusion histograms. METHODS Full diffusion tensor MR imaging was performed in 20 healthy volunteers, 20 to 91 years o...
