Sensory loss in older adults is common. Underlying factors of sensory loss in older adults include nerve degeneration, environmental insults, genetic susceptibility, or a combination of these (University of Chicago Medical Center 2016).
As you age, the way your senses (hearing, vision, taste, smell, touch) give you information about the world changes. Your senses become less sharp, and this can make it harder for you to notice details. Sensory information is converted into nerve signals that are carried to the brain.
Causes of sight loss injury or infection. genetic or age-related such as AMD (Age Related Macular Degeneration) Cataracts. Diabetic Retinopathy.
Taste impairment was the most prevalent sensory deficit, with 74% of respondents having an impaired sense of taste (26% fair/48% poor) (Table 1). Also prevalent was touch impairment, estimated to be fair in 38% of older adults and poor in 32%.
Older people can expect some decline in their five senses. While the sense of smell, taste and touch all change with age, often the most noticeable changes affect our vision and hearing. As senses change, older people may find it more difficult to socialize and participate in activities.
Loss of touch As a person ages, reduced or changed sensations result. This may be an effect of decreased blood flow to the nerve endings or to the spinal cord or brain. It can be affected by brain surgery or nerve damage from chronic disease such as diabetes.
In addition, several prospective studies have found that hearing and visual impairments in older adults independently increase the risk of cognitive impairment and dementia. Causal effects have been hypothesized due to sensory loss, precipitating social isolation, depression, and reduced physical activity.
For some people, they may also have dual sensory impairment, which is a combination of both hearing and sight loss, whilst those on the autism spectrum often have difficulty processing everyday sensory information. The largest cause of sensory impairment is considered to be the ageing process.
Have extreme sensitivity to light and visual stimulation. Find common sounds to be painful. Be sensitive to certain textures of food or clothing. Not be able to extreme heat or cold.
Certain sounds, sights, smells, textures, and tastes can create a feeling of “sensory overload.” Bright or flickering lights, loud noises, certain textures of food, and scratchy clothing are just some of the triggers that can make kids feel overwhelmed and upset.
They may already find it harder to communicate. Not being able to hear what is going on around them or hear other people speak can add to their confusion. Dementia and hearing loss can also make people feel socially isolated, so having both conditions at once can be very difficult for someone.
Mobility is reduced in people with sensory impairments and those with arthritis. The joint impact of these conditions may be underappreciated. This study examines the associations between impairments in vision, hearing, and balance and functional ability in adults with versus without arthritis.
When you first walk through the door, the delicious smell of garlic and tomatoes is almost overwhelming. You sit down to wait for a table, and after a few minutes, the scents begin to dissipate until you barely notice them. This is an example of sensory adaptation.
Which of the following sensory changes are normal with aging? Night vision becomes impaired as physiological changes in the eye occur. Older adults lose the ability to distinguish high-pitched noises and consonants. Senses of smell and taste are also decreased with aging.
Inside the inner ear is the vestibular system, where we perceive balance. This system connects to the brain, which gives us a message when we are about to fall and directs the body to take corrective action. But with age, cells in the vestibular system die off, affecting our ability to correct our position.
