Sleep Apnoea in the Elderly: Signs That Family Members Should Recognise

When your mother is sleeping increasingly poorly, snoring loudly, and waking up confused in the morning, it's easy to attribute these changes to "normal ageing." But what if these signs are masking a treatable condition that is seriously affecting her health? Sleep apnoea in elderly people is far more common than families realise, yet it often goes unrecognised or is mistaken for dementia or depression.

For families caring for an elderly parent or grandparent, recognising the signs of sleep apnoea can make the difference between an improved quality of life and a series of avoidable complications. This condition not only disrupts restful sleep, but also increases the risk of cardiovascular disease, stroke, and even accelerated cognitive decline. The good news? Once identified and properly managed, sleep apnoea can be controlled, and your loved one may regain their energy and mental clarity.

In the following sections, we will explore what sleep apnoea is, why elderly people are more vulnerable, what signs to look out for, and — most importantly — how you can offer practical help as a family member.

What sleep apnoea is and why elderly people are more at risk

Sleep apnoea is a disorder characterised by repeated pauses in breathing during sleep, with each pause typically lasting anywhere from a few seconds to a minute. These episodes are called apnoeas and can occur dozens or even hundreds of times in a single night, without the person being aware of them. The most common type in elderly people is obstructive sleep apnoea, caused by excessive relaxation of the throat muscles, which partially or completely blocks the airways.

As we age, several factors increase vulnerability to this condition. The tissues in the throat become looser, muscle tone decreases, and anatomical changes can narrow the airways. However, the risk factors go beyond the natural ageing process alone.

Age-specific risk factors

• Obesity and weight gain — excess fatty tissue around the neck increases pressure on the airways
• Cardiovascular disease — hypertension, heart failure, and arrhythmias are both risk factors for and consequences of untreated sleep apnoea
• Frequent use of sleeping tablets and sedatives — many elderly people rely on sleep aids, which relax the muscles excessively and worsen the obstruction
• Diabetes and metabolic syndrome — metabolic conditions are closely linked to sleep apnoea in a bidirectional relationship
• Hormonal changes — particularly in women after the menopause, when declining oestrogen levels increase the risk

Recent studies show that approximately one quarter to one third of adults over the age of 65 have some form of sleep apnoea, with many cases going undiagnosed. This makes the condition a significant public health issue with a direct impact on the quality of life of our elderly loved ones.

Signs that family members can observe

Recognising the signs of sleep apnoea in an elderly person can be difficult, particularly since the person themselves is unaware of most of the nocturnal episodes. This is where the family's role becomes crucial — your observations may be the first clues that lead to a diagnosis.

Night-time signs and symptoms

If you share a room or sleep close to your loved one, or if you have had the opportunity to observe them sleeping, watch out for:

• Loud and irregular snoring — not ordinary, steady snoring, but snoring interrupted by suspicious periods of silence
• Pauses in breathing — moments when breathing stops completely, followed by a gasp or a sudden awakening
• Gasping or choking — the person appears to be struggling for air while asleep
• Frequent movement and restless sleep — repeated changes of position, multiple awakenings
• Excessive night sweats — although these can have many causes, they are common in sleep apnoea

Daytime signs and symptoms

During the day, observe whether the elderly person shows any of the following:

• Excessive daytime sleepiness — dozing off during meals, in front of the television, or even mid-conversation
• Prolonged morning confusion — difficulty orientating themselves after waking, with confusion lasting longer than a brief period of grogginess
• Morning headaches — persistent headaches in the first hours of the morning that ease as the day goes on
• Mood changes — increased irritability, anxiety, or signs of depression
• Difficulties with concentration and memory — frequent forgetfulness, inability to focus on simple tasks
• Reduced energy — lack of motivation, chronic fatigue that does not improve with rest

It is important to understand that not all of these symptoms will necessarily appear at the same time, and they can vary in intensity. Any combination of them warrants attention, particularly if it represents a change from the person's usual behaviour.

Why sleep apnoea is often confused with dementia or depression

One of the most concerning aspects of sleep apnoea in elderly people is the significant overlap in symptoms with other conditions common at this age, particularly dementia and depression. This confusion can delay the correct diagnosis by months or even years, during which time untreated sleep apnoea continues to affect the brain and cardiovascular system.

Overlaps with dementia

Both sleep apnoea and dementia can present with:

• Difficulties with memory and concentration
• Confusion, particularly in the morning or evening
• Changes in personality and behaviour
• Reduced ability to carry out complex tasks

Recent research suggests that untreated sleep apnoea may even accelerate cognitive decline and increase the risk of dementia, by reducing the amount of oxygen reaching the brain during the night. The good news is that, unlike dementia, cognitive symptoms caused by sleep apnoea can be reversible once the condition is appropriately treated.

Similarities with depression

Depression in elderly people often manifests as fatigue, social withdrawal, loss of interest, and sleep disturbances — precisely the same symptoms that untreated sleep apnoea can produce. Chronic lack of restorative sleep leads to mood changes that closely mimic depression.

Distinguishing between these conditions requires professional medical assessment. Doctors can often identify sleep apnoea by asking specific questions about sleep quality and the observations of a bed partner or housemate, before arriving at a diagnosis of dementia or prescribing antidepressants that could actually worsen the apnoea.

When to seek medical advice without delay

Given how often sleep apnoea is overlooked or confused with other conditions, it is essential to understand when your observations justify seeking urgent medical attention.

Warning signs that require immediate attention

• Breathing pauses that are very frequent or prolonged — if you notice that breathing stops many times per hour, or for periods that concern you
• Daytime sleepiness that poses a safety risk — the risk of falls increases significantly, and if the person still drives, the risk of accidents is considerable
• New or worsening cardiovascular symptoms — difficult-to-control blood pressure, arrhythmias, or chest pain
• Sudden or accelerated cognitive decline — a rapid deterioration in memory or the ability to manage daily functioning
• Marked personality changes — unusual behaviour, aggression, or severe anxiety

Preparing for the appointment

To make the most of the medical visit, prepare in advance:

1. A sleep diary kept over several weeks (we will go into more detail on this below)
2. A complete list of current medications, including supplements
3. Notes on the behavioural changes you have observed and when they began
4. Specific questions for the doctor about the next steps

Do not hesitate to consult your GP even if you are not entirely certain. It is far better to check and find it is a false alarm than to allow a treatable condition to progress without treatment.

What diagnosis involves and general management options

Once the suspicion of sleep apnoea has been raised, the doctor will initiate an assessment process that may involve several stages. It is important to understand what to expect, so that you can support your loved one through the process.

The diagnostic process

The diagnosis of sleep apnoea is based primarily on polysomnography, a comprehensive sleep study. This can be carried out in two ways:

• Laboratory polysomnography — the patient spends a night at a specialist sleep centre, where brain waves, oxygen levels, heart rate, breathing, and body movements are all monitored
• Home sleep tests — for more straightforward cases, or where travel is difficult, simpler portable devices may be used, although these provide more limited information

The GP may refer the patient to a sleep medicine specialist or a respiratory physician for a full assessment. Depending on the severity of the case and any associated medical conditions, cardiology or ENT consultations may also be required.

General management approaches

It is important to stress that I will not be offering treatment advice — every case requires an individualised medical assessment and a personalised plan. That said, it is helpful to be aware of the general options available, which the doctor will discuss:

• Lifestyle changes — adjustments to weight, sleeping position, and avoidance of alcohol and sedatives
• Specialist medical devices — equipment that keeps the airways open during sleep
• Dental appliances — devices that reposition the jaw and tongue
• Surgical intervention — in selected cases where specific anatomical causes are present
• Treatment of associated conditions — management of cardiovascular disease, diabetes, or other medical conditions

The treatment plan will be tailored to the patient's age, general state of health, severity of the apnoea, and personal preferences. Close collaboration with the medical team and adherence to recommendations are essential for success.

How family members can offer practical help

The family's role does not end once a diagnosis has been made — on the contrary, your support becomes crucial in the long-term management of sleep apnoea. Here are some concrete ways in which you can help:

Adjusting sleeping position

The position in which the elderly person sleeps can significantly influence the severity of the apnoea. Many people experience more severe apnoea when sleeping on their back, as gravity pulls the tongue and soft tissues towards the back of the throat.

• Encourage sleeping on the side, using supportive pillows to maintain the position
• A specially shaped wedge pillow or slightly raising the head of the bed may help
• Avoid pillows that are too high, as these can bend the neck and worsen the obstruction

Sleep hygiene — creating a suitable environment

Good quality sleep starts with healthy habits and an appropriate environment:

• A regular schedule — going to bed and waking up at the same times, even at weekends
• A comfortable bedroom — a cool temperature (around 18–20 degrees), darkness, and quiet
• Avoiding heavy meals in the evening — the last substantial meal should be eaten at least 3 hours before bedtime
• Limiting fluids before sleep — to reduce night-time awakenings
• Avoiding alcohol and caffeine — particularly in the second half of the day
• A relaxing evening routine — light reading, soothing music, and avoiding screens

Managing medications

Discuss all of the medications your loved one is taking with their doctor. Certain sleeping tablets, sedatives, or muscle relaxants can worsen sleep apnoea. Never stop any medication without the doctor's agreement, but do raise this concern at the appointment.

Monitoring sleep and communicating with the doctor

Your systematic observations are valuable tools for the medical team. A well-kept diary can speed up the diagnosis and help to assess the effectiveness of treatment.

How to keep a sleep diary

Over a period of at least two weeks, record the following each day:

1. Bedtime and wake-up time
2. Estimated number of night-time awakenings (if you observed them)
3. Episodes of snoring or breathing pauses — describe how frequent and pronounced they were
4. Morning state — confusion, headache, how rested the person felt
5. Episodes of daytime sleepiness — when they occurred and how long they lasted
6. Preferred sleeping position
7. Medications taken — including any sleeping tablets or alcohol consumed

What information to share with the doctor

When speaking with the doctor, be prepared to describe:

• The changes you have observed and when they began
• The impact on daily life — activities that have been given up, relationships affected
• The response to any interventions already tried
• Any other new symptoms that might seem unrelated
• The full family medical history, if available

Do not downplay symptoms to avoid "bothering" the doctor, and do not exaggerate — describe faithfully what you observe. This balance helps to achieve an accurate diagnosis and an appropriate treatment plan.

Frequently asked questions

Does sleep apnoea go away on its own in elderly people?

No, sleep apnoea does not resolve spontaneously and generally worsens over time if left untreated. Even mild forms warrant medical attention, as they can progress and contribute to other health problems. With appropriate treatment, however, symptoms can be effectively managed.

Is it normal for elderly people to snore loudly?

Although snoring becomes more common with age due to changes in the throat tissues, it should not be considered "normal" — particularly when accompanied by pauses in breathing. Loud, irregular snoring is a warning signal that warrants investigation, not dismissal as part of the ageing process.

How long does it take for symptoms to improve after starting treatment?

Many patients notice improvements in daytime sleepiness and energy levels within the first few weeks of treatment. Cognitive and mood improvements may take longer, sometimes months. Each person responds differently, and the doctor will monitor progress and adjust the treatment as needed.

Can sleep apnoea really cause heart problems?

Yes, untreated sleep apnoea significantly increases the risk of high blood pressure, coronary heart disease, heart failure, and arrhythmias. Repeated pauses in breathing place the heart and blood vessels under constant stress. This is why treating sleep apnoea is important not only for sleep quality, but also for cardiovascular health.

Do I need to stop caring for my parent at home if they have sleep apnoea?

In most cases, no. Sleep apnoea can be effectively managed at home once it has been diagnosed and a treatment plan has been established. That said, family monitoring becomes more important, and ongoing collaboration with the medical team is essential. In severe cases or where multiple conditions are present, discuss with the doctor what level of care is required.

Are commercially available sleep monitoring devices reliable for diagnosis?

Apps and commercial wearables can be useful for tracking sleep quality in general, but they do not replace professional medical diagnosis. Polysomnography remains the gold standard for diagnosing sleep apnoea. You may use these devices to support your observations, but not to confirm or rule out a diagnosis on your own.

If you recognise the signs of sleep apnoea in your loved one, the most important thing you can do is act — book a medical appointment and start keeping a diary of your observations. Sleep apnoea is a treatable condition, and diagnosing and managing it can significantly improve quality of life and prevent serious complications. Do not put snoring, fatigue, or confusion down to "old age" — these may be signs of a problem that has a solution.
