changes that occur because of age-related disease, as distinct from changes associated with normal healthy aging.
In contrast to the mild decline observed in normal aging, pathological aging such as Alzheimer's disease (AD) affects global cognitive function – impairing memory, language, thinking, and reasoning, and interferes substantially with daily living capacity.
“Aging pathology” means the study of these diseases that are typical of old age and in particular the study of the general phenomena that are their primary causes.
Coronary heart disease, stroke, many types of cancer, osteoporosis, Alzheimer's disease, Parkinson's disease (PD) and other neurodegenerative disorders are examples of such diseases commonly found in elderly people. Indeed, age-associated disease underlies much of the physiological deterioration of old age.
Psychological age is how old one feels, acts, and behaves, and is thus not necessarily equal to chronological age, which is age since birth [1]. A person can therefore have a psychological age that exceeds their chronological age if they are mature or at least feel older than they really are.
Three major psychosocial theories of aging—activity theory, disengagement theory, and continuity theory—are summarized and evaluated.
In broader terms, aging can be broken down into three distinct and often related categories: biological aging, psychological aging, and social aging.
Ageing is a physiological process which impairs vitality and ultimately leads to death. It is found in all differentiated multicellular organisms. Recent theories attribute ageing to an accumulation of errors as the capacity of mechanisms for their repair and compensation becomes limited.
: altered or caused by disease. pathological changes in the body. also : indicative of disease.
Psychological/Social Issues possible as the person ages:
Changes in physical appearance may be difficult. Changes in roles/tasks that people can manage can make them feel they have less to contribute. Managing leisure time- more “free time”. Depression relatively common.
modifications which take place due to age-based illness, as independent from modifications correlated with typical healthy aging. PATHOLOGICAL AGING: "You can expect some pathological aging when diagnosed with cancer and even more so when undergoing radiation and chemotherapy that may put you into menopause."
Just because an individual falls into one or more of the four ageotypes — metabolic, immune, hepatic and nephrotic — doesn't mean that they're not also aging along the other biological pathways, Snyder said.
Age-associated cognitive decline (AACD), which is also known as non-pathological cognitive aging—is an important human experience which differs in extent between individuals and also between different stages in the life cycle. Cognitive decline is among the most feared aspects of growing old.
The brain's capacity for memory, reasoning and comprehension skills (cognitive function) can start to deteriorate from age 45, finds research published on bmj.com today.
He is a pathological liar/gambler. She has a pathological fear of heights.
(pæθəlɒdʒɪkəl ) adjective. You describe a person or their behavior as pathological when they behave in an extreme and unacceptable way, and have very powerful feelings that they cannot control. He experiences chronic, almost pathological jealousy.
Pathology is the medical discipline that describes conditions typically observed during a disease state, whereas physiology is the biological discipline that describes processes or mechanisms operating within an organism.
That's because there are actually two types of aging. Intrinsic aging occurs naturally as we grow older and is largely a product of heredity. Extrinsic aging is based almost entirely on external factors.
Chronological age is measured in years; but biological age is assessed by a person's physical and mental functions. Your biological age – also known as your physiological age – is influenced by various factors. And while genetics plays a significant role, other factors include: Diet and nutrition.
An individual who experiences chronic stress is more likely to make unhealthy lifestyle choices, which causes additional health problems. In other words, stress accelerates aging, and aging causes stress—it's a vicious cycle. Stress also affects the body on a cellular level.
Exposure to light is a top cause of premature aging: Sun exposure causes many skin problems. Ultraviolet (UV) light and exposure to sunlight age your skin more quickly than it would age naturally. The result is called photoaging, and it's responsible for 90% of visible changes to your skin.
You might be surprised to know that your face is not actually the part of your body that ages the fastest. It is, in fact, your breasts. A study, published by the journal Genome Biology has found that breast tissue is the part of the body that's most sensitive to the affects of ageing.
