Aging01:26

Aging

54
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Preventive Healthcare Services01:30

Preventive Healthcare Services

1.0K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Levels of Health Promotion and Illness Prevention01:26

Levels of Health Promotion and Illness Prevention

12.6K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

2.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Cancer Prevention02:59

Cancer Prevention

6.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Alzheimer's Disease: Treatment01:22

Alzheimer's Disease: Treatment

195
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

    Area of Science:

    • Gerontology and geriatric medicine
    • Public health and preventative medicine

    Context:

    • Frailty syndrome is a common condition associated with aging.
    • It is not an unavoidable aspect of growing older, except possibly in the final stages of life.

    Purpose:

    • To review the current knowledge on primary and secondary prevention strategies for frailty.
    • To highlight the role of primary care in managing frailty.

    Summary:

    • Primary care interventions, including promoting physical activity and nutrition, can effectively prevent the transition from pre-frailty to frailty.
    • These interventions are crucial for maintaining healthspan and quality of life in older adults.

    Impact:

    • Provides evidence-based strategies for healthcare providers to implement frailty prevention programs.
    • Empowers individuals to take proactive steps towards healthier aging and mitigating frailty risks.
