Que a depressão afecta o sono (insónias) já se sabe. E se o contrário também for verdade?

Citando:
"But could things really be the other way around? Could poor sleep be making you depressed? Over the past decade or so it has become increasingly clear that disturbed sleep often comes before an episode of depression, not afterwards, helping to do away with the notion that sleep problems are secondary to other disorders."

"It was found that participants who had been sleep deprived for approximately 35 hours showed a greater amygdala response when presented with emotionally negative pictures when compared to those who had not been sleep deprived. Interestingly, links with parts of the brain that regulate the amygdala seemed weaker, too – meaning that the participants were perhaps less able to control their emotions. Such findings could help to explain how poor sleep may actually cause difficulties such as depression."
