Neuroimaging in aging: brain maintenance
Neuroimaging studies of the aging brain provide support that the strongest predictor of preserved memory and cognition in older age is brain maintenance, or relative lack of brain pathology. Evidence for brain maintenance comes from different levels of examination, but up to now relatively few studies have used a longitudinal design. Examining factors that promote brain maintenance in aging is ...
متن کاملMemory aging and brain maintenance
Episodic memory and working memory decline with advancing age. Nevertheless, large-scale population-based studies document well-preserved memory functioning in some older individuals. The influential ‘reserve’ notion holds that individual differences in brain characteristics or in the manner people process tasks allow some individuals to cope better than others with brain pathology and hence sh...
متن کاملNeuroimaging of Healthy Cognitive Aging
Cognitive aging research and theory has, until recently, been based upon behavioral measures of cognitive performance such as response time and accuracy. Results from behavioral methodologies have indicated a general age-related decline in cognitive functions such as speed of processing, attention, perception, working memory, and cued and free recall—and age invariance when assessing cognitive ...
متن کاملMemory Encoding and Dopamine in the Aging Brain: A Psychopharmacological Neuroimaging Study
Normal aging brings with it changes in dopaminergic and memory functions. However, little is known about how these 2 changes are related. In this study, we identify a link between dopamine, episodic memory networks, and aging, using pharmacological functional magnetic resonance imaging. Young and older adults received a D2-like agonist (Bromocriptine, 1.25 mg), a D2-like antagonist (Sulpiride, ...
متن کاملStructural Neuroimaging: Brain Atrophy
Neuroimaging in Alzheimer’s disease (AD) has moved beyond the stage where it was used purely to exclude other disease processes. Structural brain magnetic resonance imaging (MRI) is useful to assess hippocampal atrophy on coronal slices; clinicians can use a simple visual rating scale, which can help to confirm the diagnosis of AD. Another useful indication for neuroimaging is to assess the con...
