Increased Amygdala Activations during the Emotional Experience of Death-Related Pictures in Complicated Grief: An fMRI Study
Open accessAbstract
Complicated grief (CG) is associated with alterations in various components of emotional processing. The main aim of this study was to identify brain activations in individuals diagnosed with CG while they were observing positive, negative, and death-related pictures. The participants included 19 individuals with CG and 19 healthy non-bereaved (NB) individuals. Functional magnetic resonance imaging (fMRI) scans were obtained during an emotional experience task. The perception of death-related pictures differed between the CG group and the NB group, with a greater activation in the former of the amygdala, putamen, hypothalamus, middle frontal gyrus, and anterior cingulate cortex. Amygdala and putamen activations were significantly correlated with Texas Revised Inventory of Grief scores in the CG group, suggesting that the higher level of grief in this group was associated with a greater activation in both brain areas while watching death-related pictures. A significant interaction between image type and group was observed in the amygdala, midbrain, periaqueductal gray, cerebellum, and hippocampus, largely driven by the greater activation of these areas in the CG group when watching death-related pictures and the lower activation when watching positive-valence pictures. In this study, individuals with CG showed significantly distinct brain activations in response to different emotional images.

Affected brain areas in prolonged grief disorder include the amygdala, the orbitofrontal cortex, the subgenual anterior cingulate cortex, the nucleus accumbens and the insula.
“Affected areas include the amygdala, the orbitofrontal cortex, the subgenual anterior cingulate cortex, the nucleus accumbens and the insula 96-101 .”
From Emerging experience with selected new categories in the <scp>ICD</scp>‐11: complex <scp>PTSD</scp>, prolonged grief disorder, gaming disorder, and compulsive sexual behaviour disorder (2022) · cites this paper as [100]
The Discussion reports greater amygdala activation in complicated grief, and the Introduction reports a prior finding of greater nucleus accumbens activation. The paper also discusses orbitofrontal and insula findings in grieving people, but does not identify the subgenual anterior cingulate cortex as affected; its cited anterior cingulate findings concern other subdivisions. The full list is therefore not supported by this source. (LLM, conf=0.86)

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.
