However some data suggest that mild changes in orientation may be a normal part of aging. [52] [53] For example, Sweet and colleagues concluded that "older persons with normal, healthy memory may have mild orientation difficulties. In contrast, younger people with normal memory have virtually no orientation problems" [53] (p. 505). So although ...
Aging is associated with many changes in the central nervous system, such as mild atrophy of the cortex, which is considered non-pathological. Aging is also associated with many neurological and neurodegenerative diseases, such as amyotrophic lateral sclerosis , dementia , mild cognitive impairment , Parkinson's disease , and Creutzfeldt ...
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 ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
This phenomenon is known as the "paradox of ageing". This may be a result of social comparison; [146] for instance, the older people get, the more they may consider themselves in better health than their same-aged peers. [147] Elderly people often associate their functional and physical decline with the normal ageing process. [148] [149]
In 2007–2009, the most frequently occurring conditions among older people in the United States were uncontrolled hypertension (34%), arthritis (50%), and heart disease (32%). [52] Chronic mucus hypersecretion (CMH), defined as "coughing and bringing up sputum", is a common respiratory symptom in elderly people. [53]
An elderly couple exhibiting typical signs of physical aging At the sensory level, changes occur to vision, hearing, taste, touch, and smell. Two common sensory changes that begin in midlife include our ability to see close objects and our ability to hear high pitches.
Age-related changes are observed in fine structure of spindle nerve innervation in the form of axonal swelling and expanded/abnormal endplates. [6] When subject to a task of proprioception, the elderly show increased cocontraction of agonist-antagonist muscles, perhaps to increase gamma drive and spindle sensitivity. It is believed to be used ...
