Summary

To explore reliable neuroimaging biomarkers for anxiety disorder and OCD,and whether there are shared imaging biomarkers between different subtypes of anxiety disorder and OCD, the investigators included30 drug-naive general anxiety disorder (GAD),30 drug-naïve panic disorder(PD),30 drug-naïve social anxiety disorder,30 drug-naive.obsessive-compulsive disorder patients and 30 healthy controls by using a combination of cross-section and longitudinal study designs, including a longitudinal study in patients with anxiety disorder and OCD with 4 weeks of selective serotonin reuptake inhibitor (SSRI) paroxetine treatment. The investigators will also evaluate the severity of symptom, social function, cognitive function and treatment response.

Detailed description

Previous studies suggest that there are brain anatomical and functional in patients with anxiety disorder and obsessive-compulsive disorder (OCD). However, it remains unclear whether these abnormalities can be used for the diagnosis of anxiety disorder、OCD and prediction of treatment effects. It is also unclear whether there are shared imaging biomarkers between different subtypes of anxiety disorder and OCD.And it still lacks reliable neuroimaging biomarkers in anxiety disorder and OCD. Based on the previous studies, this study aims to examine the whole-brain anatomical and functional abnormalities in 30 general anxiety disorder (GAD),30 panic disorder(PD),30 social anxiety disorder,30 obsessive-compulsive disorder patients and 30 healthy controls by using a combination of cross-section and longitudinal study designs, including a longitudinal study in patients with anxiety disorder and OCD with 4 weeks of selective serotonin reuptake inhibitor (SSRI) paroxetine treatment.First, neuroimaging biomarkers are definitively selected in subjects at different subtypes of anxiety disorder and OCD population for the purpose of diagnosis by using a cross-section design. After that, a longitudinal study is conducted in patients with anxiety disorder and OCD with 4 weeks of paroxetine treatment to validate that the selected neuroimaging biomarkers can be used to predict treatment response of medication. The definitively selected neuroimaging biomarkers are expected to be useful for the diagnosis of anxiety disorder and OCD, and prediction of treatment effects; and finally be helpful for understanding the pathophysiology of anxiety disorder and OCD.
