Sleep Apnea and Cognitive Function in Subjects With Subjective or Mild Cognitive Impairment

This study is testing whether people with early memory concerns — either mild cognitive impairment or subjective cognitive complaints — also have undiagnosed obstructive sleep apnea. Participants wear a home sleep monitor to check for sleep apnea. It is an observational study, not a drug trial, meaning researchers are looking for a connection rather than testing a treatment. The goal is to understand whether sleep apnea is a contributing factor in early cognitive decline.

You may qualify if

  • Aged 18 years and above
  • Clinical diagnosis of mild cognitive impairment (MCI) based on Petersen's criteria. The criteria include the following: (1) memory problems, (2) objective memory disorder, (3) absence of other cognitive disorders or repercussions on daily life, (4) normal general cognitive function and (5) absence of dementia OR,
  • Diagnosis of subjective cognitive impairment, based on the subject's own complaint of cognitive impairment but with an unremarkable assessment of the Hong Kong version of Montreal Cognitive Assessment scores
  • Able to speak and read Chinese
  • Adequate visual and auditory to perform a cognitive test

You're excluded if

  • Diagnosed psychiatric illness with or without medication, e.g. major depressive disorder.
  • Other clear organic causes of cognitive impairment, e.g. old stroke, brain tumour, dementia with Lewy body, Parkinson's disease, normal pressure hydrocephalus, neurosyphilis, autoimmune encephalitis, substance abuse, history of alcohol abuse.
