Elderly Sleep Apnoea Living Alone: The Silent Driver of Dementia, Stroke & Falls
Obstructive sleep apnoea (OSA) affects an estimated 30–50% of Australians over 65 — rising to 70% in residential aged care. Most don't know they have it, because the partner who would notice has often passed away. Living alone, the loud snoring and breathing pauses go unwitnessed; the daytime fatigue is dismissed as “getting old.”
Untreated OSA in elderly people doubles stroke risk, doubles dementia risk, raises fall rates, drives heart failure, and worsens depression. CPAP therapy reverses most of this — but only 40–60% of older Australians stay compliant. This guide covers how to recognise OSA in someone living alone, the diagnostic pathway via Medicare, CPAP basics, and how daily wellness calls support compliance.
Sleep Apnoea Impact in Older Australians

Signs of OSA in Someone Living Alone
What They Notice Themselves
- • Waking unrefreshed despite full night sleep
- • Falling asleep watching TV or after meals
- • Morning headaches
- • Dry mouth in morning (mouth-breathing)
- • Nighttime urination 3+ times
- • Difficulty concentrating
- • Mood deterioration
Family/Caller May Notice
- • Falling asleep mid-conversation
- • Slurred or slow speech later in day
- • Reduced engagement on afternoon calls
- • Memory complaints from parent
- • Reports of car drowsiness (driving risk)
- • Leg swelling (right heart strain)
- • Recurrent falls
The STOP-BANG Quiz (a Quick Self-Check)
Ask: Snoring loudly? Tired during day? Observed breathing pauses? Treated for high Pressure? BMI >35? Age over 50? Neck size >40cm? Gender male? Three or more “yes” answers warrants a sleep study.
Diagnosis Pathway in Australia
GP appointment
STOP-BANG screen, Epworth Sleepiness Scale, exam (neck, BMI, BP). Bulk-billed.
Sleep study (polysomnography)
Home-based or in-lab. Bulk-billed under Medicare item 12203/12204 if criteria met. Measures apnoea/hypopnoea index (AHI).
Severity classification
AHI 5–15: mild OSA. AHI 15–30: moderate. AHI >30: severe. Treatment recommended for moderate or severe, plus mild with significant symptoms.
CPAP titration trial
2–4 week trial via sleep clinic or CPAP supplier. Mask fitting, pressure adjustment.
Equipment funding
DVA covers CPAP fully. Some private health includes it. Otherwise $1,500–$3,000 self-funded. Some state-based equipment schemes (Vic SWEP, NSW EnableNSW).
CPAP Compliance: Why Elderly Stop Using It
Common Reasons for Non-Compliance
- • Mask discomfort or pressure sores on face
- • Claustrophobia
- • Difficulty putting on mask with arthritis
- • Dry mouth, nasal congestion
- • Embarrassment with new partner/visitors
- • “I feel fine without it” once symptoms resolve
- • Forget if cognition declining
Solutions That Work
- • Try multiple mask styles (nasal vs full-face vs pillow)
- • Heated humidifier (most modern CPAPs include)
- • Slow ramp pressure increase
- • Daily check-in calls asking “Did you wear your CPAP?”
- • CPAP usage data review with sleep specialist
- • Family encouragement — even children adult kids reminding
- • Mandibular advancement splint as alternative
Daily Calls Track Sleep Apnoea Recovery
What Calls Track
- • Morning energy levels week to week
- • CPAP compliance with gentle prompts
- • New headaches, dizziness, falls
- • Daytime drowsiness
- • Cognitive engagement during call
- • Mood improvements as treatment works
