Sleep apnoea after a stroke is a common sleep disorder that causes repeated pauses in breathing while you sleep. These interruptions reduce oxygen levels, disturb sleep and may slow stroke recovery. Many stroke survivors don't realise they have sleep apnoea because it happens while they are asleep. Learn the signs, causes, treatments and why recognising sleep apnoea is important for your recovery.

After your stroke...

You wake up feeling exhausted.

You sleep for hours...

But never feel refreshed.

Your partner says...

You snore loudly.

Or...

They've noticed you stop breathing during the night.

You begin wondering...

"Could something be happening while I sleep?"

For many stroke survivors...

The answer is yes.

The Good News

Sleep apnoea can often be diagnosed and treated.

Improving your sleep may increase your energy, support rehabilitation and improve your overall quality of life.

Many people notice a significant difference once their sleep apnoea is managed.

✦ ✦ ✦

What Is Sleep Apnoea?

Sleep apnoea is a condition where your breathing repeatedly stops and starts during sleep.

Each pause may last several seconds before your brain briefly wakes you enough to restart breathing.

Most people don't remember these awakenings.

However...

They prevent you from getting deep, restorative sleep.

✦ ✦ ✦

Can a Stroke Cause Sleep Apnoea?

Yes.

Sleep apnoea is common after a stroke.

Some people had undiagnosed sleep apnoea before their stroke.

Others develop it afterwards because the stroke affects the brain areas involved in controlling breathing or weakens the muscles that keep the airway open during sleep.

✦ ✦ ✦

Types of Sleep Apnoea

Obstructive Sleep Apnoea (OSA)

This is the most common type.

The muscles in the throat relax too much during sleep, temporarily blocking the airway.

✦ ✦ ✦

Central Sleep Apnoea (CSA)

This is less common.

The brain temporarily fails to send the normal signals telling the breathing muscles to work.

Some stroke survivors develop central sleep apnoea depending on the area of the brain affected.

✦ ✦ ✦

Symptoms

You may notice:

✓ Loud snoring.

✓ Waking up gasping for air.

✓ Morning headaches.

✓ Dry mouth on waking.

✓ Poor-quality sleep.

✓ Feeling extremely tired during the day.

✓ Difficulty concentrating.

✓ Memory problems.

✓ Irritability.

Often, a partner notices the pauses in breathing before the person affected does.

✦ ✦ ✦

Why Does Sleep Apnoea Matter After a Stroke?

Poor sleep affects your brain's ability to recover.

Sleep apnoea may:

✓ Reduce oxygen levels during sleep.

✓ Increase daytime fatigue.

✓ Reduce concentration.

✓ Slow rehabilitation.

✓ Affect memory.

✓ Worsen mood.

✓ Reduce quality of life.

Untreated sleep apnoea is also associated with an increased risk of future cardiovascular problems, including another stroke.

✦ ✦ ✦

How Is Sleep Apnoea Diagnosed?

If your doctor suspects sleep apnoea, they may recommend a sleep assessment.

This may involve:

✓ A home sleep study.

✓ An overnight sleep study in a specialist sleep centre.

These tests monitor:

✓ Breathing.

✓ Oxygen levels.

✓ Heart rate.

✓ Sleep patterns.

The results help determine whether sleep apnoea is present and how severe it is.

✦ ✦ ✦

Treatment Options

Treatment depends on the type and severity of your sleep apnoea.

✦ ✦ ✦

CPAP Therapy

The most common treatment for obstructive sleep apnoea is Continuous Positive Airway Pressure (CPAP).

A CPAP machine delivers gentle air pressure through a mask worn during sleep.

This helps keep your airway open and reduces breathing interruptions.

Many people notice improved energy and alertness once they become used to using CPAP.

✦ ✦ ✦

Lifestyle Changes

Your healthcare professional may recommend:

✓ Maintaining a healthy weight.

✓ Avoiding alcohol close to bedtime.

✓ Stopping smoking if you smoke.

✓ Sleeping on your side if appropriate.

These changes may help reduce symptoms in some people.

✦ ✦ ✦

Managing Other Medical Conditions

Treating nasal congestion, allergies or other health conditions may also improve breathing during sleep.

✦ ✦ ✦

Ongoing Stroke Rehabilitation

Improving your overall health through physiotherapy, exercise and healthy lifestyle habits supports both recovery and better sleep.

✦ ✦ ✦

Practical Tips

Don't Ignore Loud Snoring

Loud, regular snoring—especially if accompanied by pauses in breathing—should be discussed with your doctor.

✦ ✦ ✦

Take Daytime Sleepiness Seriously

Feeling constantly exhausted despite spending enough time in bed is not something you should simply accept.

✦ ✦ ✦

Use Your CPAP Machine Consistently

If you're prescribed CPAP, using it every night gives you the greatest benefit.

It may take time to adjust, but persistence often pays off.

✦ ✦ ✦

Maintain Good Sleep Habits

Keep a regular bedtime routine and create a quiet, comfortable sleeping environment.

Healthy sleep habits complement medical treatment.

✦ ✦ ✦

Attend Follow-Up Appointments

Sleep apnoea treatment sometimes needs adjustments.

Regular reviews help ensure your treatment is working effectively.

✦ ✦ ✦

Tips for Family and Carers

If you're supporting someone after a stroke:

✓ Watch for loud snoring or pauses in breathing.

✓ Encourage them to discuss symptoms with their doctor.

✓ Support consistent use of CPAP if prescribed.

✓ Encourage healthy sleep habits.

✓ Understand that daytime tiredness may have a medical cause.

Recognising sleep apnoea early can make a significant difference.

✦ ✦ ✦

When Should You Seek Medical Advice?

Arrange an appointment with your healthcare professional if:

✓ You snore loudly most nights.

✓ Someone notices you stop breathing during sleep.

✓ You regularly wake up gasping for air.

✓ You're excessively sleepy during the day.

✓ Poor sleep is affecting your recovery.

Seek urgent medical attention immediately if:

✓ You suddenly develop new weakness.

✓ You experience facial drooping.

✓ Your speech becomes slurred.

✓ You become confused.

These may be signs of another stroke.

My Perspective

Sleep isn't simply about feeling rested.

It's one of the times when your brain works hardest to repair itself.

If your breathing is interrupted dozens of times every night...

Your brain never gets the uninterrupted rest it needs.

Treating sleep apnoea isn't just about sleeping better.

It's about giving your recovery the best possible chance.
