Sleep Apnoea: Common, Underdiagnosed and Cognitively Significant

A substantial number of people with cognitive complaints have an untreated sleep disorder they do not know about.

What it is

Obstructive sleep apnoea involves repeated partial or complete airway collapse during sleep, causing oxygen desaturation and brief arousals that fragment sleep. Episodes can occur many times an hour without the person waking consciously. Risk factors include higher body weight, male sex, older age, large neck circumference, alcohol and certain anatomical features, though it occurs in people with none of these.

Why it is missed

The person is asleep and cannot observe it. Snoring is common and dismissed. Daytime sleepiness is attributed to overwork or age. People living alone have nobody to notice breathing pauses. It is not routinely screened for unless raised. Estimates of undiagnosed prevalence are substantial, and it is more common in people with cardiovascular and metabolic conditions.

Cognitive consequences and what to do

Untreated apnoea has been associated with impaired attention, executive function and memory, attributed to both sleep fragmentation and intermittent hypoxia. It is also associated with cardiovascular risk and daytime accident risk. Signs worth acting on: loud habitual snoring, witnessed breathing pauses, gasping or choking at night, waking unrefreshed despite adequate hours, morning headaches, nocturia and daytime sleepiness. Home sleep studies have made assessment much more accessible, and treatment improves daytime function substantially.

Key takeaways

  • Episodes fragment sleep many times an hour without conscious waking
  • People living alone have nobody to notice breathing pauses
  • Both fragmentation and intermittent hypoxia are implicated cognitively
  • Home sleep studies have made assessment considerably more accessible
