Study Notes
Senescence and Aging Process
- Biological processes leading to aging begin before birth.
- Aging encompasses the period from onset of old age to death.
- Rate and effects of aging differ among individuals, not strictly aligning with chronological age.
- Influencing factors include genetic makeup, lifestyle choices, health status, and cardiovascular fitness.
- Women generally have a longer lifespan than men.
- General reduction in bodily functions occurs, impacting particularly non-regenerative tissues: CNS, skeletal muscle, cardiac muscle, and kidneys.
Theories of Aging
- Theorized causes of aging include:
- Genetically programmed aging
- Apoptosis (programmed cell death)
- Wear and tear from accumulated waste (e.g., altered proteins, lipofuscin)
- Degenerative collagen changes and random errors during cell division
- Telomere shortening with each cell division, correlating with aging signs
- Latent viruses, such as those causing chicken pox, may reactivate as shingles in older age.
- Accumulation of free radicals and peroxides damages nucleic acids, potentially leading to cancers and other diseases.
- Hormonal changes generally maintain constant levels, except for estrogen and testosterone fluctuations.
Physical Changes and Health Implications
- Weight fluctuations are common with aging.
- Female reproductive system undergoes changes contributing to mood swings and fatigue.
- Dyspareunia occurs due to thinning vaginal mucosa and decreased glandular secretions, along with sleep disturbances linked to hot flashes.
Skin and Hair Changes
- Aging skin exhibits thinning, increased fragility, reduced dermal thickness, and diminished subcutaneous tissue.
- Decreased specialized structures (sweat glands, receptors) lead to dryness and wrinkling.
- Hair grays due to reduced melanocyte numbers, with visible thinning and follicle loss.
Cardiovascular Changes
- Aging leads to decreased size and number of cardiac muscle fibers, with increased fatty tissue and collagen.
- Heart valves thicken, and vascular changes may reduce oxygen supply, contributing to diminished cardiac reserve and potential heart failure.
- Pathologies include:
- Arteriosclerosis: Loss of elasticity and thickening of arteriolar walls causing tissue ischemia.
- Atherosclerosis: Hyperlipidemia promotes cholesterol accumulation, leading to angina, myocardial infarctions, and strokes.
Bone Health and Osteoporosis
- Osteoporosis results in calcium and bone mass loss, particularly in postmenopausal women, making fractures common in the spine, pelvis, and limbs.
- Risk reduction strategies include:
- Increased calcium and vitamin D intake.
- Walking and weight-bearing exercises.
- Physiotherapy, drugs like bisphosphonates, and individualized hormone therapy.
- Bone density testing recommended for women at age 50 or earlier.
Digestive and Urinary System Changes
- Muscle weakness and fatigue are prevalent, with constipation often leading to hemorrhoids.
- Overstimulation of vagus nerves in older adults can cause dysrhythmias and low blood pressure.
- Urinary changes include weakened sphincters leading to nocturia and incontinence.
Immune System and Overall Health
- Aging causes a decline in the immune system’s efficacy, with reduced production of T and B cells.
- Older adults may face increased infection risk due to diminished lymphocyte effectiveness.
- Skin breakdown can predispose individuals to infection.
- Multiple disorders are common, necessitating integrated treatment for interrelated health issues.
- Management of medications is vital; adjustments may be needed due to unpredictable absorption, distribution, and elimination in older adults.
- Polypharmacy is prevalent; medication reconciliation is essential for safety.
