As a carer, it’s important to know what sensory loss is, how to recognise and differentiate it from expected age-related changes, and how to make adjustments for older people living with, or developing, sensory loss.
This article provides advice on how you can support an older adult experiencing sensory loss (specifically, loss of hearing, vision, taste, smell and/or touch) in order to improve their safety, enjoyment, and quality of life. Keep in mind sensory loss can relate to a range of age-related physiological and psychological changes.
Changes to hearing, vision, taste, smell and touch impact the way a person experiences the world.
Sensory loss can impact:
Communication
Quality of life
Daily living
Enjoyment
Socialisation, engagement and interaction
Personal safety
Independence
Wellbeing.

Sensory loss in older adults is common. An American study found that 94% of older adults have one type of sensory loss; 38% have two; and 28% have three to five. These statistics are strongly associated with age, gender and race (University of Chicago Medical Center 2016).
In Australia, 93% of people over 55 years of age are experiencing a long-term vision disorder and 49% of people over 75 are experiencing a long-term hearing disorder (AIHW 2016).
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).
A person is legally blind if they can’t see at six metres what someone with normal vision can see at 60 metres, or if their field of vision is less than 20 degrees in diameter.
As a person ages their smell sensitivity reduces. A loss of smell implicates the ability to taste.
Causes include: side effects of smoking, nasal mucus, adaptation (olfactory cells become flooded).
(Better Health Channel 2014)
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.
(MedlinePlus 2020)
Dual sensory loss:
Dual sensory loss, also known as ‘deafblindness’, is the impairment of both hearing and sight.
About 100,000 Australians have deafblindness, two thirds of these being older adults over 75 years of age.

How to Care for and Communicate with Someone who has Hearing Loss
If a person in your care is over the age of 65, they should have their hearing tested every year (My Aged Care 2016).
As an individual:
Stand in front of them when you’re speaking to them and avoid speaking from another room
Say the person’s name before you start talking to them, giving them a chance to focus before you begin
Speak to the person with hearing difficulties rather than their interpreter (if they have one)
Speak slowly and carefully without over-emphasising or distorting your lip movements
Raise your voice if necessary but avoid shouting
Utilise body language and facial expression when you speak, providing context
Consider writing messages if reading is less of a challenge for the person
Certain phrases may be harder to hear, so try to come up with a different way of saying something if a person is having trouble understanding you
Keep in mind that facial hair, eating or chewing, and having your hands in front of your face will make it more difficult for the person to understand you
Reduce additional environmental noise
Ensure that hearing aids are functional and checked regularly
Reduce other distractions that may be present in the room.
Investigate whether visual alerts such as alarm clocks and front door alerts may benefit the person
Install assistive-listening devices to enable the person to contact people in an emergency.
(My Aged Care 2016)
How to Care for and Communicate with Someone who has Vision Loss
A person’s chance of developing a visual impairment rises significantly after the age of 40 (My Aged Care 2016).
State your name clearly as you arrive
Use a neutral voice when speaking
Use everyday language - don’t avoid words such as ‘look’ and ‘see’ in fear of causing offence
Continue to use body language as it can affect your tone of voice
If you are moving around a room or about to leave, make sure to let the person know
Help or instruct a resident when eating, for example, let them know where food is placed on their plate and what its temperature is
If you move something in a resident’s room, make sure to let them know
Be mindful of tripping hazards such as cords, wet floors, mops and buckets
Be aware that a half-open door is a hazard; keep doors either open or shut
If a person requests your assistance in walking, let them take your arm and guide them by walking slowly, while removing or describing obstacles in their path.

How to Care for Someone who has Oral Sense Loss
With age, a person’s taste buds decrease in number and shrink, and their sensitivity to smell and taste diminishes (MedlinePlus 2020).
This not only impairs the enjoyment of eating, but can also reduce the person's ability to sense certain dangers (e.g. being unable to smell smoke from a fire) (MedlinePlus 2020).
Review the person’s medicines to determine whether any medicines are affecting their smell and taste, and adjust if appropriate
Use different spices or flavours during food preparation
Implement safety devices (e.g. gas detectors).
(MedlinePlus 2020)
How to Care for Someone with Loss of Touch
The cause of a loss of touch as a person ages is likely the combination of a general loss of sensory acuity and comorbid conditions such as arthritis and cerebrovascular disease (Wickremaratchi & Llewelyn 2006).
A reduced sense of touch or feeling makes it difficult for older people to detect temperature, pain, vibration, pressure and/or texture. Talk to them about how you can make them more comfortable in the event of this sensory loss (Wickremaratchi & Llewelyn 2006; MedlinePlus 2020).
How to Care for and Communicate with Someone who has Deafblindness
Communication preferences for people living with deafblindness depend upon the extent to which the person’s vision and/or hearing are affected (Deafblind Information Australia 2019).
Consider the following modes of communication:
Lip reading
Auslan
Co-active signing: respectfully moulding a person’s hands to make signs
Tactile signing: placing your hand over the hand of the signer to feel or read the signs
Visual field signing: signing within the confined area of their vision
Braille
Printing on their palm
The use of communication devices.
(Deafblind Information Australia 2020)
Guiding:
Always respect the person’s guiding preferences
When guiding, stand beside the person on their preferred side. Stay half to a whole step ahead of them as you guide and indicate obstacles.
