Poor sleep may affect specific area of brain causing negative emotions

New York: According to the information given by a study where researchers have studied that improper sleep may affect a particular area of the brain which is known to be involved in causing negative emotional responses.




This happens especially with the people who are suffering from depression and anxiety leading in the restriction of their ability to think positively and give positive emotional responses.




The study said that this area of the brain, the dorsal anterior cingulated cortex, may have to work harder to modify negative emotional responses in people with poor sleep who have depression or anxiety.




Assistant Professor at University of Illinois at Chicago College of Medicine in the US, Heide Klumpp went on to say: “Our research indicates sleep might play an important role in the ability to regulate negative emotions in people who suffer from anxiety or depression.”




The research team used functional MRI to measure the activity in different regions of the brain as participants were challenged with an emotion-regulation task.




The 78 participants in the study were between ages 18 and 65 and had been diagnosed with an anxiety disorder, a major depressive disorder, or both.




Participants were shown disturbing images of violence — from war or accidents — and were asked to simply look at the images and not to try to control their reaction or to “reappraise” what they saw in a more positive light.




An example of reappraisal would be to see an image of a woman with a badly bruised face and imagine her as an actress in makeup for a role, rather than as a survivor of violence, Klumpp said.

“Reappraisal is something that requires significant mental energy,” she said.




“In people with depression or anxiety, reappraisal can be even more difficult, because these disorders are characterized by chronic negativity or negative rumination, which makes seeing the good in things difficult,” Klumpp added.

The researchers found this to be true in those with lower levels of sleep efficiency.
