Associations of mind morphology and severity of insomnia, melancholy and anxiousness signs. Credit score: Nature Psychological Well being (2025). DOI: 10.1038/s44220-025-00412-8
Insomnia, melancholy, and anxiousness are the commonest psychological issues. Remedies are sometimes solely reasonably efficient, with many individuals experiencing returning signs. Because of this it’s essential to seek out new leads for therapies. Notably, these issues overlap lots, usually occurring collectively. Might there be a shared mind mechanism behind this phenomenon?
Siemon de Lange, Elleke Tissink, and Eus van Someren, along with their colleagues from the Vrije Universiteit Amsterdam, investigated mind scans of greater than 40,000 individuals from the UK Biobank. The analysis is printed within the journal Nature Psychological Well being.
Tissink says, “In our lab, we explore the similarities and differences between insomnia, anxiety, and depression. Everyone looks at this from a different perspective: some mainly look at genetics and in this study, we look at brain scans. What aspects are shared between the disorders, and what is unique to each one?”
Overlap and variations
“We investigated many different aspects, like the structure and connectivity of the brain tissue. In all three disorders, we observe a reduced surface area of the cerebral cortex, a smaller thalamic volume, and weaker connectivity between different brain regions.”
“As well as, some abnormalities are distinctive to every dysfunction. For instance, the severity of insomnia seems to be extra carefully associated to smaller volumes within the mind areas related to reward.
“The severity of depression, on the other hand, seems to be more strongly related to a thinner cerebral cortex in brain areas associated with language and emotion. Instead, anxiety is more severe with weaker amygdala reactivity and functional connectivity between regions where dopamine, glutamate, and histamine play a crucial role in communication.”

Comparable mind circuit
However what can we finally do with this info? Tissink continues, “The areas appear separate from one another, however whenever you map them out collectively, all of them become a part of the identical circuit (amygdala–hippocampus–medial prefrontal cortex circuit). So, though they’re distinct areas, all of them seem to signify totally different items of vulnerability throughout the identical puzzle.
“Quite a lot of analysis has been accomplished on the overlap between anxiousness and melancholy, however insomnia is usually forgotten. That is the primary time that now we have investigated all three issues on the identical time, on such a giant scale. The comorbidity is extraordinarily excessive: individuals could expertise these issues in several levels of their lives, or expertise them abruptly.
“There is a lot of discussion about the underlying mechanisms. The treatment of insomnia, for example, sometimes also improves depression—but why? By further investigating this question, we hope to find new leads for follow-up research, as well as better treatments.”
