People who report sleep apnea develop cognitive decline a decade earlier, study finds.
People with breathing problems during sleep – called sleep apnea – develop mild cognitive impairment (MCI) a decade earlier finds a new study published today (15 April 2015) in the journal Neurology.
The medical histories of 2,470 people aged 55 to 90 taking part in the Alzheimer’s Disease Neuroimaging Initiative (ADNI) study were reviewed for the development of MCI or Alzheimer’s disease. Participants were also asked to report whether they suffered from sleep apnea and whether or not they received treatment with a continuous positive airway pressure (CPAP) machine during the night.
On average, people with sleep apnea were diagnosed with MCI in their 70s, a decade earlier than people without sleep breathing problems. The relationship between having sleep apnea and the age of diagnosis of Alzheimer’s disease in the study was much less clear.
