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]
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 ...
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]
Oxidative stress is the most controllable risk factor and is the best understood. The online Merriam-Webster Medical Dictionary defines oxidative stress as, "physiological stress on the body that is caused by the cumulative damage done by free radicals inadequately neutralized by antioxidants and that is held to be associated with 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]
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.
Hutchinson-Gilford progeroid syndrome (HGPS) is an extremely rare autosomal dominant genetic disorder in which symptoms resembling aspects of aging are manifested at an early age. [8] Its occurrence is usually the result of a sporadic germline mutation ; although HGPS is genetically dominant, people rarely live long enough to have children ...
Ageing is associated with increased risk of cancer, Alzheimer's disease, diabetes, cardiovascular disease, increased mental health risks, and many more. [5] [6] Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes. [7]
