Wandering Mind Behind Insomnia?
(Ivanhoe Newswire) – Researchers at the University of California, San Diego have discovered a new brain imaging study that may help explain why people with insomnia often complain that they struggle to concentrate during the day even when objective evidence of a cognitive problem is lacking.
The research team studied 25 people with primary insomnia and 25 good sleepers. The study subjects underwent a functional magnetic resonance imaging scan while performing a working memory task. The MRI scans revealed that people with insomnia could not modulate activity in brain regions typically used to perform the task. The study also revealed that as the task got harder, participants with insomnia could not dial down the "default mode" regions of the brain that are normally only active when our minds are wandering; proving that when people have insomnia, not only do they have problems sleeping, but they also have problems being efficient during the day.
