Abstract

Background Elevated rate of aging-related biological and functional decline, termed "accelerated aging," is reported in patients with schizophrenia (SCZ) and major depressive disorder (MDD). We used diffusion tensor imaging derived fractional anisotropy (FA) as a biomarker of aging-related decline in white matter (WM) integrity to test the hypotheses of accelerated aging in SCZ and MDD. Methods The SCZ cohort comprised 58 SCZ patients and 60 controls (aged 20-60 years). The MDD cohort comprised 136 MDD patients and 351 controls (aged 20-79 years). The main outcome measures were the diagnosis-by-age interaction on whole-brain-averaged WM FA values and FA values from 12 major WM tracts. Results Diagnosis-by-age interaction for the whole-brain average FA was significant for the SCZ (p = .04) but not the MDD (p = .80) cohort. Diagnosis-by-age interaction was nominally significant (p<.05) for five WM tracts for SCZ and for none of the tracts in the MDD cohort. Tract-specific heterochronicity of the onset of age-related decline in SCZ demonstrated strong negative correlations with the age-of-peak myelination and the rates of age-related decline obtained from normative sample (r =-.61 and-.80, p<.05, respectively). No such trends existed for MDD cohort. Conclusions Cerebral WM showed accelerated aging in SCZ but not in MDD, suggesting some difference in the pathophysiology underlying their WM aging changes. Tract-specific heterochronicity of WM development modulated presentation of accelerated aging in SCZ: WM tracts that matured later in life appeared more sensitive to the pathophysiology of SCZ and demonstrated more susceptibility to disorder-related accelerated decline in FA values with age. This trend was not observed in MDD cohort.

  • The greater sensitivity of white matter to aging in schizophrenia may account for the greater prevalence of cingulum changes in those with well-established psychotic states.

    “may account for the greater prevalence of cingulum changes in those with well-established psychotic states.”

    From The cingulum bundle: Anatomy, function, and dysfunction (2018) · cites this paper as Kochunov et al., 2013

    The Results and Discussion report accelerated white-matter aging in schizophrenia and greater vulnerability in some tracts. They do not establish a greater prevalence of cingulum changes in people with well-established psychotic states, or test whether accelerated aging accounts for that prevalence. (LLM, conf=0.85)

  • White matter, including the cingulum, is especially sensitive to the effects of aging in schizophrenia.

    “Evidence that white matter, including the cingulum, is especially sensitive to the effects of aging in schizophrenia (Kochunov et al., 2013)”

    From The cingulum bundle: Anatomy, function, and dysfunction (2018) · cites this paper as Kochunov et al., 2013

    The Results (page unavailable) report accelerated age-related white-matter decline in schizophrenia, with numerically greater decline across all twelve tracts. They do not identify the cingulum as especially sensitive: the regional Results name five tracts with nominally significant age-by-diagnosis interactions, and the cingulum is not among them. (LLM, conf=0.83)

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.
