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]
Progeroid syndromes (PS) are a group of rare genetic disorders that mimic physiological aging, making affected individuals appear to be older than they are. [1] [2] The term progeroid syndrome does not necessarily imply progeria (Hutchinson–Gilford progeria syndrome), which is a specific type of progeroid syndrome.
Progerin may also play a role in normal human aging, since its production is activated in typical senescent cells. [18] Unlike other "accelerated aging diseases", such as Werner syndrome, Cockayne syndrome, or xeroderma pigmentosum, progeria may not be directly caused by defective DNA repair. These diseases each cause changes in a few specific ...
Roughly 20% of persons greater than 60 years of age have a neurological disorder, with episodic disorders being the most common, followed by extrapyramidal movement disorders and nerve disorders. [15] Diseases commonly associated with old age include Multiple system atrophy [16] Parkinson's disease [17] Alzheimer's disease [18] Stroke. [19]
The subarachnoidal lymphatic-like membrane, whose discovery was reported around 2023, likely plays a role in cerebrospinal fluid functions and, as both a protective barrier and a host of immune cells that monitor the brain for infection and inflammation, appears to be substantially involved in major brain diseases and brain aging.
Depression is one of the most common disorders that is present in old age and is usually comorbid with other physical and psychiatric conditions, perhaps due to the stress induced by these conditions. [93] In older adults, depression presents as impairments already associated with age such as memory and psychomotor speed. [94]
An aging-associated disease (commonly termed age-related disease, ARD) is a disease that is most often seen with increasing frequency with increasing senescence. They are essentially complications of senescence, distinguished from the aging process itself because all adult animals age ( with rare exceptions ) but not all adult animals ...
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".
