Abstract

Heroin addiction has been associated with impaired neuronal connectivity and cognitive deficits. One mechanism that potentially explains these findings is alterations in white matter connectivity secondary to chronic opiate use. However, few studies have quantitavely examined white matter deficits in opiate addiction (OA). Here, we investigated white matter microstructure in OA using diffusion tensor imaging (DTI). We performed voxel‐wise analysis of fractional anisotropy (FA) in 24 participants with OA and 29 healthy controls. The OA group showed reduced FA in multiple pathways including the corpus callosum, thalamic radiation and inferior longitudinal fasciculus. This FA reduction was mainly the result of increased radial diffusivity (λ⊥), indicative of myelin pathology. Longer duration of OA was also associated with axonal diffusivity (λ 1), most robustly in superior longitudinal fasciculi and right frontal white matter suggesting axonal injury in long‐term users. Together, the findings indicate that chronic OA use has widespread and diverse effects on neuronal connectivity and function.

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.
