Normal aging is associated with a decline in various memory abilities in many cognitive tasks; the phenomenon is known as age-related memory impairment (AMI) or age-associated memory impairment (AAMI). The ability to encode new memories of events or facts and working memory shows decline in both cross-sectional and longitudinal studies. [8]
Researchers describe a way by which the aging of select immune system T cells can be prevented or is slowed down, with relevance to life extension and making vaccines more durable. [207] [208] The discovery of "super neurons" in the entorhinal cortex of people over age 80 who show exceptional episodic memory is reported. [209] [210]
Episodic memory (remembering specific events) declines gradually from middle age, while semantic memory (general knowledge and facts) increases into early old age and then declines thereafter. [9] Older adults can exhibit reduced activity in specific brain regions during cognitive tasks, particularly in medial temporal areas related to memory ...

The development of memory is a lifelong process that continues through adulthood. Development etymologically refers to a progressive unfolding. Memory development tends to focus on periods of infancy, toddlers, children, and adolescents, yet the developmental progression of memory in adults and older adults is also circumscribed under the umbrella of memory development.
Gerontology (/ ˌ dʒ ɛr ən ˈ t ɒ l ə dʒ i / JERR-ən-TOL-ə-jee) is the study of the social, cultural, psychological, cognitive, and biological aspects of aging.The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek γέρων (gérōn), meaning "old man", and -λογία (), meaning "study of".
However, memory loss is qualitatively different in normal aging from the kind of memory loss associated with a diagnosis of Alzheimer's (Budson & Price, 2005). Research has revealed that individuals' performance on memory tasks that rely on frontal regions declines with age.
These results are important to demonstrate that aging is not accompanied by a decline in episodic memory due to a reliance on semantic memory as previously thought. [31] The remember-know distinction was integral in achieving these results as well as understanding the ways in which autobiographical memory works and the prevalence of the ...
