Subcortical volume changes seen in obsessive-compulsive disorder

23 Sep 2016
A world-wide meta-analysis showed that paediatric and adult obsessive-compulsive disorder (OCD) have different patterns of subcortical abnormalities.

Previous OCD studies produced inconsistent brain imaging findings due to small sample size and clinical heterogeneity. In the present study, the investigators conducted a meta- and mega-analyses of data from OCD centers worldwide.

The study analyzed T1 images from 1,830 OCD patients and 1,759 control subjects. Coordinated and standardized processing was used for profiling subcortical brain volume changes between the two groups.

A meta-analysis was conducted on the mean left and right hemosphere measurements of each subcortical structure. Pooled volumetric measurements were used for mega-analysis.

Results of the meta-analysis showed significantly smaller hippocampal volumes and larger pallidum volumes among adult OCD patients. Both findings were more pronounced in medicated patients. Significantly larger thalamic volumes were seen in unmedicated paediatric patients. Sample characteristics did not mediate the findings. Similar findings were obtained in the mega-analysis.

These findings also suggest the importance of possible neurodevelopmental alterations in OCD based on significant subcortical abnormalities in adult and paediatric OCD.
