Sleep apnea signs
Key points
- Sleep apnea is very common in older adults with dementia, but it is often missed because symptoms overlap with dementia itself.
- The classic signs are loud snoring, gasping, choking, or pauses in breathing during sleep—ask a bed partner or record audio.
- Daytime sleepiness, worsening confusion, and new agitation can all be signs of untreated sleep apnea.
- A sleep study (in-lab or home) is the only way to diagnose sleep apnea. Do not rely on guesswork.
- CPAP is the gold standard treatment and can be used successfully by many people with dementia, with patience and support.
- Treating sleep apnea can improve cognition, reduce agitation, and improve quality of life for both the person with dementia and the caregiver.

Step-by-step
Observe and document nighttime signs for at least a week: sit quietly for 15–20 minutes after your loved one falls asleep, listening for loud snoring, snorting, gasping, or breathing pauses of 10 seconds or more, and record a short audio or video on your phone. Ask anyone sleeping nearby what they hear.
Track daytime red flags for a week: unusual sleepiness, dozing off while reading, watching TV, or during conversations, and any new or worsening confusion, irritability, or late-afternoon 'sundowning'—write down specific examples with dates.
Review all current medications with a pharmacist or doctor—sedatives (like benzodiazepines), muscle relaxants, opioids, and alcohol can relax the airway and worsen apnea. Never stop or change a medication on your own; ask specifically whether any could be making the breathing problem worse.
Schedule a visit with the primary care provider.
What not to do
Do not stop, change, or adjust any medication without consulting the prescriber.
Do not assume snoring is harmless—it can signal sleep apnea, which may worsen confusion and dementia symptoms.
Practical tools
Smartphone audio/video recorder
Use your phone to record short clips of breathing during sleep; play them for the doctor to help diagnose sleep apnea.
Discuss with your clinician
Ask the doctor: ‘Could my loved one’s medications (especially sedatives, opioids, or muscle relaxants) be making sleep apnea worse? Should any be adjusted?’
Ask: ‘Is a home sleep test appropriate, or does my loved one need an in-lab study? What are the pros and cons for someone with dementia?’
If CPAP is recommended, ask: ‘What settings should we start with? How do we clean the mask and tubing? What do we do if my loved one refuses to wear it?’
Ask: ‘Are there any alternative treatments like oral appliances or positional therapy that might work for my loved one?’
If your loved one has heart disease or has had a stroke, ask: ‘Could this be central sleep apnea? How is that diagnosed and treated differently?’
Ask: ‘How often should we follow up? What signs should I watch for that indicate the treatment is not working?’
