Abstract

Background Brain mechanisms of chronic insomnia, a highly prevalent condition, have barely been investigated. We demonstrate here a decrease in orbitofrontal gray matter (GM) volume that strongly correlates with the severity of complaints.Methods In a case-control study, optimized voxel-based morphometry was used to compare the regional brain volumes of 24 medication-free chronic primary insomnia patients (age range 52-74 years, 17 women), carefully selected to exclude psychiatric comorbidity, with those of 13 matched control subjects without sleep problems (age range 50-76 years, 9 women). Additionally, the correlation of regional volumes with insomnia severity was investigated.Results Patients had a smaller volume of GM in the left orbitofrontal cortex, strongly correlating (r = -.71) with the subjective severity of insomnia. Furthermore, reduced GM volume was found in the anterior and posterior precuneus. Patients did not show increased GM volume in any area. No group differences were found for white matter volume.Conclusions This is the first voxel-based morphometry study showing structural brain correlates of insomnia and their relation with insomnia severity. Functional roles of the affected areas in decision-making and stimulus processing might better guide future research into the poorly understood condition of insomnia.

  • The severity of sleep complaints in insomnia patients correlated with structural abnormalities in the part of the orbitofrontal cortex that is essential for the evaluation of comfort.

    “Interestingly, these observations were recently supported by our finding [5] that the severity of their sleep complaints correlated with structural abnormalities in the part of the orbitofrontal cortex that is essential for the evaluation of comfort [27, 73].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
