Study Notes

Session Objectives

Define key terms related to disease processes.
Explain the effects of aging on different body systems.
Identify various disorders in each body system.
Discuss the pathophysiology behind these disorders.

Key Terminologies

Aetiology: Refers to the underlying cause of a disease.
Pathogenesis: The process through which a disease develops.
Complications: Unfavorable outcomes of diseases or treatments.
Prognosis: Expected outcome based on medical expertise.
Pathophysiology: Changes in body function due to disease.
Disorder: Abnormality indicating incomplete health.

Important Concepts in Pathophysiology

Changes can be short-term or result in long-term conditions impacting health for years.
Functional changes may vary from minor to significant clinical symptoms.
Understanding structural changes is essential as they often accompany functional changes.

Aging Effects on Body Systems

Integumentary System

Thinning of skin layers and reduced elasticity lead to wrinkles and increased fragility.
Increased susceptibility to skin conditions such as eczema, fungal infections, and shingles.

Cardiovascular System

Decrease in heart efficiency and muscle strength.
Structural alterations include stiffening of arteries and loss of pacemaker cells.
Conditions like hypertension, hypotension, and congestive heart failure are common.

Respiratory System

Reduced lung function and efficiency, affecting gas exchange.
Increased weakness in respiratory muscles and hardening of airways.
Common disorders include asthma, COPD, pneumonia, and influenza.

Nervous System

Diminished brain size and reduced synaptic connections.
Altered sleep patterns and cognitive decline may lead to conditions like dementia and Parkinson's disease.

Musculoskeletal System

Decreased bone density leading to brittle bones and stiffness in joints.
Slower reflexes and increased difficulty with balance and movement.
Conditions such as osteoporosis and osteoarthritis are prevalent.

Gastrointestinal System

Changes in oral musculature may affect swallowing and digestion efficiency.
Reduced appetite related to oral health and decreased taste sensitivity.
Common issues include constipation, gastritis, and diverticulitis.

Endocrine System

Altered hormone production resulting in decreased metabolic function.
Conditions like diabetes mellitus and thyroid issues become more common.

Urinary System

Weakened pelvic floor muscles lead to regulation issues with incontinence.
Declining bladder capacity and filtration rate increase the likelihood of urinary tract infections.

Reproductive System

In men, prostate enlargement and reduced testosterone levels impact sexual function.
In women, menopause leads to atrophy and hormonal changes affecting libido.

Special Senses

Altered sensory functions can significantly affect daily living.
Common vision impairments: cataracts, glaucoma, diabetic retinopathy, and macular degeneration.
Hearing impairment is frequent, impacting balance and orientation.

Societal Impact of Aging

Sudden or gradual sensory loss may lead to disorientation and behavioral changes.
Increased compensation through other senses may occur in response to impairments.
