Exam 3 Lifespan pt 1

An age-related loss of muscle mass and strength

The ability to focus and maintain an image on the retina—declines most sharply between the ages of 40 and 59.

40

High-pitched

High blood pressure, high cholesterol, and cardiovascular disease increase considerably.

Characterized by hypertension, obesity, and insulin resistance, and often leads to the onset of diabetes and cardiovascular disease.

Lung tissue becomes less elastic ~ age 55, decreasing lung capacity.

Wakeful periods become more frequent in the forties, as do sleep-disordered breathing and restless legs syndrome.

The leading chronic disorder in middle age, followed by hypertension

the maximum number of years an individual can live

120-125

the number of years the average person born in a particular year will probably live

•Individuals 100 years and older.
•Increasing each year in developed countries.
Supercentenarian refers to those who live to be 110

those aged 65 to 84

those aged 85 or more

Loss of acuity even with corrective lenses, less transmission to light, greater susceptibility to glare, color discrimination ability decreases

Significant loss of visual acuity and color discrimination, decrease in size of perceived visual field. In late old age, significant risk for visual dysfunction via cataracts and glaucoma

Significant loss of hearing at high frequencies, some loss at middle frequencies. Losses can be helped by hearing aid. Greater susceptibility to masking what is heard by noise.

Significant loss at high and middle frequencies. Hearing aid more needed than young-old age

Visual decline in late adulthood is linked to cognitive decline, fewer social contacts, and less challenging social/leisure activities.

the thickening of eye's lens causes vision to become cloudy, opaque, and distorted.

damage to the optic nerve because of the pressure created by a buildup of fluid in the eye

deterioration of the retina's macula, which corresponds to focal center of the visual field.

Characteristic age-related hearing impairment involving selective difficulty hearing high-pitched tones. This condition is not curable.

Wax in the outer ear canal, which may be related to the increase of the earlobe in aging by several millimeters
