According to a new study, lack of sleep can promote atrophy (shrinkage) of the brain and cognitive decline. The brain is responsible for cognitive abilities; therefore, faster shrinkage of the brain is associated with decline in cognitive performance. The study was published on July 1 in the journal SLEEP by researchers at the Center for Cognitive Neuroscience, Neuroscience and Behavioral Disorders Program, Duke-NUS Graduate Medical School, Singapore.
The objective of the study was to examine the impact of sleep duration and quality to age-related changes in brain structure and cognitive performance among relatively healthy older adults. The study group comprised 66 relatively healthy adults aged 55 years or older (average age: 67 years) at the beginning of the study. The seniors underwent magnetic resonance imaging (MRI) and neuropsychological assessment every two years. Self-reported sleep duration was recorded and blood samples for high-sensitivity C-reactive protein were drawn. (C-reactive protein is a marker for systemic inflammation.). Continue reading.
