Adolescents with internet addiction disorder showed decreased gray matter volume in several brain regions and altered white matter fractional anisotropy.

Plain English Summary

Summary written for general audiences

Researchers examined brain structure in 18 adolescents with internet addiction disorder using voxel-based morphometry and diffusion tensor imaging. Voxel-based morphometry showed reduced gray matter volume in the bilateral dorsolateral prefrontal cortex, supplementary motor area, orbitofrontal cortex, cerebellum, and left rostral anterior cingulate cortex. Diffusion tensor imaging revealed increased fractional anisotropy in the left posterior limb of the internal capsule and decreased fractional anisotropy in the right parahippocampal gyrus white matter.

Why This Matters

The study aimed to investigate microstructure abnormalities in adolescents with internet addiction disorder. The researchers provided evidence of multiple structural brain changes in adolescents with internet addiction disorder. The authors suggested that long-term internet addiction results in brain structural alterations that probably contribute to chronic dysfunction.

Our results suggested that long-term internet addiction would result in brain structural alterations, which probably contributed to chronic dysfunction in subjects with IAD. The current study may shed further light on the potential brain effects of IAD.

Quick Questions About This Study

Decreased gray matter volume was found in the bilateral dorsolateral prefrontal cortex, supplementary motor area, orbitofrontal cortex, cerebellum, and left rostral anterior cingulate cortex.
Enhanced fractional anisotropy was found in the left posterior limb of the internal capsule, while reduced fractional anisotropy was found in the right parahippocampal gyrus white matter.
Gray matter volumes in the dorsolateral prefrontal cortex, rostral anterior cingulate cortex, and supplementary motor area, and white matter fractional anisotropy changes in the posterior limb of the internal capsule correlated significantly with addiction duration.
The study included 18 adolescents with internet addiction disorder and used voxel-based morphometry and diffusion tensor imaging.
The researchers suggested that long-term internet addiction results in brain structural alterations that probably contribute to chronic dysfunction.
