Proteins build up in the brain faster among people with sleep disorders

People who have sleep disorders may have an increased risk of developing dementia, studies show. Research teams from Wheaton College in the US explored the associations between sleep disordered breathing and hallmark Alzheimer’s proteins in the brain. In the first study, they looked at the accumulation of amyloid protein in the brains of 516 healthy older people who did not have memory problems. They found that people with self-reported sleep disordered breathing had higher levels of amyloid in the brain as measured by brain scans. Over time, they saw that amyloid accumulated at a faster rate in those with sleep disordered breathing compared with those without. The research team in the second study looked at 798 people with mild memory problems, known as mild cognitive impairment (MCI). Not everyone with MCI goes on to develop dementia, however a person with MCI is at an increased risk of developing Alzheimer’s or another form of dementia.   Excerpt from Health Insurance Daily, read the full article here.
