Elderly rodents typically die of cancer or kidney disease, but not of cardiovascular disease. In humans, the relative incidence of cancer increases exponentially with age for most cancers, but levels off or may even decline by age 60–75 [ 3 ] (although colon / rectal cancer continues to increase).
A number of expert groups have proposed an increase in dietary protein recommendations for older age groups to 1.0–1.2 g/kg body weight per day. [48] [49] Ensuring adequate nutrition in older adults is of interest in the prevention of sarcopenia and frailty, since it is a simple, low-cost treatment approach without major side effects. [50]
Recurring infections by latent herpes viruses can exhaust the immune system of elderly persons. [12] Consistent, repeated stimulation by such pathogens leads to preferential differentiation of the T-cell memory phenotype, and a 2020 review reported that CD8+ T-cell precursors, specific for the most rare and less frequently present antigens shed ...
Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. [3]
Inflammation is a general marker of tissue damage in any disease, and may be either secondary to tissue damage in Alzheimer's disease or a marker of an immunological response. [114] There is increasing evidence of a strong interaction between the neurons and the immunological mechanisms in the brain.
Geriatrics, or geriatric medicine, [1] is a medical specialty focused on providing care for the unique health needs of the elderly. [2] The term geriatrics originates from the Greek γέρων geron meaning "old man", and ιατρός iatros meaning "healer".
Risk Factors. Risk factors for hip pain make you more likely to experience it. Some (but not all) overlap with the causes of hip pain, such as different types of arthritis and injuries.
Many older adults notice a decline in their attentional abilities. [54] Attention is a broad construct that refers to "the cognitive ability that allows us to deal with the inherent processing limitations of the human brain by selecting information for further processing". [ 55 ]
