Brain areas badociated with short-term memory, self-emotion, and negative emotions are related to depression that may cause patients to linger on bad thoughts and to experience bad feelings sleep quality, suggests a study. % of people with depression report significant levels of sleep disturbances, such as difficulty in falling asleep and a short sleep – also known as insomnia.
People suffering from insomnia also run an increased risk of depression and anxiety.
"The understanding we develop here is consistent with the areas of the brain involved in short-term memory, the self, and the negative emotion is strongly related to depression, and this leads to an increase in ruminant thoughts which are at least part of the mechanism that impairs the quality of sleep, "said Jianfeng Feng, of the University of Warwick in Britain.
For the study, published in the journal JAMA Psychiatry, the team examined the neural mechanisms underlying the relationship between depression and sleep quality in approximately 10,000 people
found a strong link between the dorsolateral prefrontal cortex – badociated with short-term memory – the self-badociated precuneus. – and the lateral orbitofrontal cortex – badociated with a negative emotion – in people suffering from depression.
The increase in functional connectivity between these brain regions provides a neural basis for the relationship between depression and poor sleep quality
a neural basis for understanding how depression is related to poor quality sleep, and this has implications for treating depression and improving sleep quality because of brain areas identified "
