aging changes in hearing, hearing aids, tongue, sense of sight, aged eye anatomy, aging changes, in the senses, perceptual changes related to growing older, way senses, taste, smell, touch, vision, hearing, able, to give information, the world changes, senses, become less acute, have trouble distinguishing details, sensory changes, tremendous impact on lifestyle, have problems, communication, enjoyment of activities, social interactions, sensory changes, contribute to a sense of isolation, the senses receive information of some type, environment, light, sound vibrations, converted to a nerve impulse, carried, brain, where it is interpreted into a meaningful sensation, everyone, a certain minimum amount, stimulation, a sensation is perceived, minimum level, the threshold, aging increases this threshold, sensory input needed to be aware, the sensation becomes greater, in the body part related, sensation account, the other sensation changes, hearing, vision changes, the most dramatic, all senses, aging, the aging changes, in the senses, compensated, equipment glasses, hearing aids, by minor changes in lifestyle, hearing, ears have two jobs, one is hearing, is maintaining balance, hearing occurs after vibrations cross the eardrum, inner ear, changed into nerve impulses, carried, brain by the auditory nerve, balance, equilibrium, controlled, portion, the inner ear, fluid, small hairs, in the semicircular canal, labyrinth, stimulate the nerve that helps the brain maintain balance, ear structures deteriorate, eardrum often thickens, inner ear bones, structures, becomes increasingly difficult to maintain balance, hearing, decline slightly, that of high-frequency sounds, been exposed to a lot of noise, younger, age-related hearing loss, presbycusis, sharpness, acuity, hearing, decline slightly beginning, age 50, in the auditory nerve, brain, slightly decreased ability to process, translate sounds into meaningful information, impacted ear wax is another cause of trouble hearing, more common, increasing age, impacted ear wax removed in doctor's office, hearing loss is inevitable, estimated that 30% of all people over 65 have significant hearing impairment, conductive hearing loss occurs, sound has problems getting, the external, middle ear, surgery, a hearing aid helpful, type of hearing loss, depending on the specific cause, sensorineural hearing loss involves damage, inner ear, auditory nerve, brain, type of hearing loss, not respond to treatment, persistent, abnormal ear noise, tinnitus, another fairly common hearing problem, older adults, vision, vision occurs, light is processed by eye, interpreted by brain, light passes, the transparent eye surface, cornea, pupil, opening, eye interior, becomes larger, smaller to regulate the amount, light that enters eye, colored portion, iris, muscle that controls the pupil size, inside of eye is filled, a gel-like fluid, flexible, transparent lens that focuses light on retina, the eye, retina converts light energy into a nerve impulse that, carried, brain, interpreted, age-related eye changes, 30s, aging eyes produce less tears, dry eyes, quite uncomfortable, find relief by using eyedrops, artificial tears solutions, the eye structures change, aging, cornea becomes less sensitive, injuries, not be noticed, by the time turn 60, pupils decrease to, one-third, the size they were, were 20, pupil, react more slowly in response to darkness, bright light, lens becomes yellowed, less flexible, slightly cloudy, fat pads supporting the eye decrease, eye sinks back, socket, eye muscles, become less able to fully rotate the eye, sharpness of vision, visual acuity, gradually decline, glasses, contact lenses, help correct age-related vision changes, eventually need bifocals, everyone older than 55 needs glasses at least part, the time, change is not universal, 15% to 20% of older people have bad enough vision to impair driving ability, 5%, become unable to read, most common problem is difficulty focusing the eyes, a condition, presbyopia, less able to tolerate glare, find, more trouble adapting to darkness, bright light, many older people find that although vision is good enough to drive, must give up night driving, glare, brightness, darkness, significant difficulty, night driving the first sign of a cataract, a clouding, the eye lens, indoor glare, glare, a shiny floor, sunlit room, make it difficult to get around inside, people of all ages, harder to distinguish blues, greens than it, distinguish reds, yellows, becomes more pronounced, aging, age increases, using warm contrasting colors, yellow, orange, red, improve ability to tell where things, makes it easier to perform daily activities, many older people find that keeping a red light on in darkened rooms, hallway, bathroom, makes it easier, than using a "regular" night light, red light produces less glare than a regular incandescent bulb, aging, fluid inside eye, change, small particles, create "floaters" in vision, annoying, floaters oftentimes, not indicate a dangerous condition, not reduce vision, suddenly develop floaters, experience a rapid increase, in the number of them, should definitely have eyes checked by a professional, eyes, examined, not be able to move eye in all directions, upward gaze limited, objects, visual field, gets smaller, reduced peripheral vision is common, limit social interaction, older people, not communicate, people sitting next to them, they cannot see them well, perhaps at, food, drinks spilled, driving, become dangerous, common eye disorders, in the elderly, not normal, cataracts, glaucoma, senile macular degeneration, diabetic, hypertensive retinopathy, taste and smell, senses of taste, smell interact closely, helping appreciate food, most taste really comes from odors, sense of smell begins at nerve receptors high, in the membranes, the nose, have approximately 9,000 taste buds, taste buds, primarily responsible, sensing sweet, salty, sour, bitter tastes, smell, to a lesser extent, taste, play a role in both safety, enjoyment, we detect certain dangers, spoiled food, noxious gases, smoke, taste, smell, a delicious meal, pleasant aroma, improve social interaction, enjoyment of life, number of taste buds decreases beginning at, age 40 to 50 in women, at 50 to 60 in men, each remaining taste bud also begins to atrophy, lose mass, sensitivity, four taste sensations, decrease, after age 60, taste sensation is lost, salty, sweet tastes, lost, bitter, sour tastes lasting slightly longer, additionally, mouth produces less saliva, dry mouth, make swallowing more difficult, makes digestion slightly less efficient, increase dental problems, sense of smell, diminish, after age 70, related to loss of nerve endings, in the nose, studies, the cause of decreased sense of taste, smell, aging have conflicting results, studies have indicated that normal aging by produces very little change in taste, smell, changes related to diseases, smoking, environmental exposures over a lifetime, regardless, decreased taste, smell, lessen interest, enjoyment in eating, become less aware of personal hygiene, the sense of smell is decreased, enjoyment of environment diminished, in the way food is prepared, change, in the spices used, people, an increased risk of asphyxia, they cannot detect the odor of natural gas, stove, furnace, appliance, a visual gas detector that changes appearance, natural gas is present helpful, touch, vibration, and pain, sense of touch also includes awareness of vibrations, pain, skin, muscles, tendons, joints, internal organs have receptors that detect touch, temperature, pain, brain interprets the type, touch sensation, interprets the sensation, pleasant, comfortably warm, unpleasant, very hot, neutral, aware, touching something, medications, brain surgery, in the brain, confusion, nerve damage from trauma, chronic diseases diabetes, change this interpretation, changing awareness, the sensation, recognize a painful sensation, does not bother you, the receptors give the brain information, the position, condition of internal organs, though you, not be consciously aware of this information, helps to identify changes, pain of appendicitis, many studies have shown, aging, have reduced, changed sensations of pain, vibration, cold, heat, pressure, touch, hard to tell whether these changes, related to aging, disorders that occur more often, in the elderly, the normal changes of aging, decreased blood flow, touch receptors, brain, spinal cord, minor dietary deficiencies, decreased thiamine levels, a cause of changes, regardless, experience changes, in the touch-related sensations, they age, find it harder, to tell the difference, cool, cold, decreased temperature sensitivity increases the risk of injuries frostbite, hypothermia, burns, reduced ability to detect vibration, touch, pressure increases the risk of injuries, pressure ulcers, after age 50, have reduced sensitivity to pain, develop problems, walking, reduced ability to perceive where body is in relation, floor, fine touch, decrease, develop an increased sensitivity to light touch, thinner skin, people older than 70, to increase safety, make allowances, changes in touch-related sensations, limit the maximum water temperature in house, an adjustment on the water heater, to reduce the risk of burns, look, thermometer to decide how to dress rather than waiting, feel overheated, chilled, inspect skin, feet, injuries, find an injury, treat it, don't assume that just, an area is not painful, injury is not significant, related topics, aging changes in organs, tissues, cells, aging changes in skin, aging changes, in the bones muscles, joints, aging changes, in the face, aging changes, in the nervous system.
