What leads to graying of hair? - Fewer melanocytes
What happens to skin with aging? - Skin atrophies
Less collagen (Less elasticity)
Skin drier (Xerosis)
Skin is slower to heal
Decreased in skin's sensory ability
Bright purple-colored patches with well-demarcated edges
Located on the dorm of forearms and hands
Lesions eventually resolve over several weeks - Senile Purpura
Tan to brown colored macule on the dorm of hands from sun damage - Lentigines
Stasis dermatitis - affects lower legs and ankles secondary to chronic edema
What is precancerous lesion of squamous cell carcinoma? - Actinic Keratosis
Loss of elasticity of the lens - Presbyopia
Presbyopia symptoms - Close vision is affected
Arcus senilis - Opaque grayish-to-white ring at the periphery of the cornea
Not associated with visual changes
Caused by deposition of cholesterol and fat
Cataracts - Cloudiness and opacity of the lens of the eyes
, Cataracts symptoms - Decreased night vision
Sensitivity to glare of car lights
Hazy vision
Red reflex disappears
Test for cataracts - Red reflex
Loss of central visual fields - Macular Degeneration
Macular Degeneration screening - Amsler grid
What frequency is lost first in aging? - High-frequency
Presbycusis - sensorineural hearing loss related to aging
What happened to the forced vital capacity with age? - Decreases
What happens to residual volume in lungs with age? - Increases due to decrease in lung and chest
wall compliance
Which type of immunity is more affected by aging? - Cellular immunity more than humoral immunity
- Cellular involves T-lymphocytes, macrophages, and the cytokines
- Humoral associated with B-lymphocytes and antibody
S4 in the elderly - Can be considered normal and not associated with heart disease symptoms
Increase in numbers of floaters or specks on the visual field
Flashes of light
Sensation that a curtain is covering part of the visual field - Retinal Detachment
