Why are prescription drugs produce more severe side effects in the elderly?
Frontotemporal lobar degeneration
Ageism , also spelled agism, is stereotyping and/or discrimination against individuals or groups on the basis of their age. This may be casual or systematic. The term was coined in 1969 by Robert Neil Butler to describe discrimination against seniors, and patterned on sexism and racism.
The term ” ageism ” refers to two concepts: a socially constructed way of thinking about older persons based on negative attitudes and stereotypes about aging and a tendency to structure society based on an assumption that everyone is young, thereby failing to respond appropriately to the real needs of older persons.
Understanding the basic biology of neural stem cells and the molecular and cellular regulation mechanisms of neurogenesis in young and aged brain will allow us to modulate cell replacement processes in the adult brain for the maintenance of healthy brain tissues and for repair of disease states in the elderly.
Major and mild neurocognitive disorders can occur with Alzheimer’s disease, degeneration of the brain’s frontotemporal lobe, Lewy body disease, vascular disease, traumatic brain injury, HIV infection, prion diseases, Parkinson’s disease, Huntington’s disease, or another medical condition, or they can be caused by a
General changes that researchers think occur during brain aging include: Brain mass: Shrinkage in the frontal lobe and hippocampus, which are areas involved in higher cognitive function and encoding new memories, starts at around the age of 60 or 70 years.
Some examples of ageism include: losing a job because of your age. being refused interest-free credit, a new credit card, car insurance or travel insurance because of your age. receiving a lower quality of service in a shop or restaurant because of the organisation’s attitude to older people.
She said that the term ” elderly ” should be thrown out altogether – the preferred terminology is “seniors” or “older adults.” Even many active older Americans don’t consider themselves “seniors” at all.
You are protected from age discrimination This means that people cannot discriminate against you because of your age where you work or live, or when providing services. Some special programs and benefits, such as seniors’ discounts or youth employment programs, deal with genuine age-related needs.
The percentages reporting each type of ageism are presented in Table 1 . The most frequent type of ageism , reported by 58 percent, was Item 1: “I was told a joke that pokes fun at old people.”
Examples of Ageism in Health Care Physicians may dismiss a treatable pathology as a feature of old age. Staff members may share ageist jokes or may have implicit ageist thoughts and behaviors toward elderly patients without conscious awareness. Providers may also treat the natural effect of aging as a disease.
Demographic differences are associated with different levels of median income for units aged 65 or older . Income is highest for married couples, who have a median income more than 2½ times that of nonmarried persons.
In older age, there are again comparatively strong changes in personality. On average, individuals tend to increase in agreeableness and tend to decrease in conscientiousness in this period of life, but there are also considerable individual differences in developmental trajectories.
At what age does a person have the greatest number of neurons – before birth, during childhood, during adolescence, or during adulthood? The neuron number is greatest before birth.
With increasing age , dendrites shrink, their branches become less complex, and they lose dendritic spines, the tiny protuberances that receive chemical signals. Finally, the formation of new neurons — a process called neurogenesis — also declines with age .
