Memory 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 کاملAutobiographical memory and aging
Autobiographical memory, or memory for personal experiences, allows individuals to define themselves and construct a meaningful life story. Current research aims to review the definition and theories of autobiographies memory and how it usually changes or abnormally in older adults. Base on studies, as we grow older autobiographical memory drops off, also semantic memory changes a little or som...
متن کاملNeuroimaging 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 کاملNMDA receptor function, memory, and brain aging
An increasing level of N-methyl-D-aspartate (NMDA) receptor hypofunction within the brain is associated with memory and learning impairments, with psychosis, and ultimately with excitotoxic brain injury. As the brain ages, the NMDA receptor system becomes progressively hypofunctional, contributing to decreases in memory and learning performance. In those individuals destined to develop Alzheime...
