A new study suggests that when your mind and body are in a deep sleep, your body may be more productive.
The findings could help doctors diagnose depression in patients.
Researchers at the University of Michigan and the University at Buffalo used functional magnetic resonance imaging (fMRI) to scan volunteers for the presence of two brain areas: the dorsolateral prefrontal cortex (DLPFC), which regulates mood and emotions, and the ventromedial prefrontal cortex, which governs impulse control.
The participants who had the most frequent “dizziness” had the highest activity in both brain areas.
In some studies, fMRI has shown that patients with depression often have trouble keeping their attention on tasks, and these studies have suggested that the brain is more sensitive to “drowsiness” than the rest of the brain.
The study was published online April 2 in the Journal of Neuroscience.
“We’re actually looking at the brain as a tool for monitoring your mood and your mood changes,” said the study’s lead author, Dr. Robert Schulman.
“This research suggests that you might be able to actually use the brain to monitor your mood.”
In the study, the researchers scanned the brains of 15 volunteers with depression and 14 with a healthy control group.
They found that the participants who slept most had the densest activity in the brain’s right diencephalon, the area that sits between the hippocampus and the frontal cortex.
The researchers say this finding might help doctors and researchers better understand what causes depression.
“You’re waking up to the fact that your brain is actually being more and more attentive to the things that it has to be more attentive on,” said Schulmans senior author and postdoctoral fellow Daniela Alvarado.
“I think this is a big thing to be able say about the brain in depression, because it might be the key to the cure.”
Alvarados said the researchers found that during deep sleep the drowsiness in the participants’ brains was not only a marker for depression, but it was also correlated with a reduced activity in other brain areas, such as the insula and the amygdala.
The insula, for example, is involved in a variety of emotions, including anger, fear, and pleasure.
The amygdala is involved with emotions like sadness and anxiety.
The results suggest that people with depression are more sensitive and sensitive to drowsying-induced drowsierness.
“What this research shows is that even when you have a little bit of drowsyness, it can be useful to have your attention on certain tasks or to get your attention to certain situations,” said Alvaradas.
“It could be a very useful tool for people in depression to help them manage that attention deficit disorder.”
What’s more, the study suggests people with severe depression who are not able to sleep can still benefit from treatment.
“That’s the way I see it,” said study co-author Dr. Daniel J. DeFries, an assistant professor of psychiatry at the Yale School of Medicine.
“A person is less likely to have depression if they’re getting more sleep than they are if they have depression.”
The research team is still analyzing the data to see if the brain activity of people with depressive disorders might be related to other psychiatric disorders.
Alvaros believes that the study provides a clue to what may be causing depression in people with the condition.
“Our findings indicate that people who have depression may be especially vulnerable to drowiness, because the drowist is more likely to be depressed than someone who’s not depressed,” she said.
“If you have depression, you might have a lower threshold for drowsies.”
AlVarados and DeFures believe that, like many other diseases, depression could be triggered by a variety issues.
For example, there could be an underlying genetic issue that affects how your brain works.
AlVaradas hopes the study will help people better understand the disease process.
“The idea that we can identify and target the brain and help people with this disorder to better manage their illness is really exciting,” said DeFresses co-director, Drs.
Anna Koehler and Michael E. Cramer.
“There’s so much more that we know about depression and depression disorders.
We can actually help people who are at risk of depression to manage their condition better.”
