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 supporting an older person experiencing sensory loss (specifically, loss of hearing, vision, taste, smell, and/or touch) to improve their safety, enjoyment and quality of life.
Sensory Loss Under the Strengthened Aged Care Quality Standards
Changes to hearing, vision, taste, smell and touch impact how 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 people 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 65 years of age are experiencing a long-term vision disorder (AIHW 2021), and 50% of people aged 60-70 have some kind of hearing loss - this increases to 80% after 80 years of age (DoHaAC 2024).
Underlying factors of sensory loss in older people 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 6 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 and adaptation (olfactory cells becoming flooded).

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.

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 people 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 2024).
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 expressions 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 if a person is having trouble understanding you, try devising a different way of saying something.
Remember 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 help in an emergency.

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 2024).
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’ because you fear offending the person.
Continue to use body language, as it can affect your tone of voice.
If you are moving around a room or are about to leave, make sure to let the person know.
Help or instruct a person when eating, for example, let them know where food is placed on their plate and its temperature.
If you move something in a person'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 then 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 2022).
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 2022).
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 2022)
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 (Wickremaratchi & Llewelyn 2006; MedlinePlus 2022).
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 2021).
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
