Changes During Normal Aging
Basic Facts
Aging is a process that requires adaptation to the changes associated wtih the increasing age. Care for the elderly involves, among others, the management of most common clinical conditions that affict the aged such as arthritis, hypertension, diabetes mellitus, urinary incontinence, heart disease, hearing loss, influenza, depression, falls and injuries.
Preventive strategies should be targeted at the major causes of death such as coronary heart disease, cancer, and stroke. Replacement therapy with estrogens and progesterone decreases the incidence of osteoporosis. Principal goal of health care to the elderly: Delaying morbidity and disability.
Physical Activity: Older adults should be counseled on physical exercise when there are no contraindications such as decompensated heart failure, severe aortic stenosis, serious cardiac arrhtymias etc.
Brain: atrophy of the brain tissue, senile plaques, neurofibrillary tangles, loss of memory
Respiratory System: Increase in FRC with aging, decrease in pulmonary diffusing capacity, decrease in arterial oxygen tension
Cardiovascular system: decrease in cardiac index, increase in myocardial stiffness, decrease in arterial compliance, increase in total peripheral vascular resistance
Renal System: glomerulosclerosis, impaired sodium handling
Sleep: Wakefulness After Sleep Onset, Increased number of arousals, insomnia
Which of the following is a common process associated with normal aging?
A.increase in cardiac fibrosis
B. increase in cardiac index
C. Decrease in total peripheral vascular resistance
D. Decrease in WASO (Wakefulness After Sleep Onset)
Answer: A
