Diffusion Tensor Imaging in Obsessive-Compulsive Disorder
Yukiko Saito et al in Radiology 2008;246:536-542 have examined the examine microstructural white matter abnormalities in the corpus callosum (CC) of patients with obsessive-compulsive disorder (OCD). A significant reduction in FA was observed in the rostrum of the CC in patients with OCD compared with the rostral FA in the control subjects. (FA-Fractional anisotropy). Study results support the widely held view that the orbital prefrontal region is involved in the pathophysiology of OCD and indicate that the orbitofrontal circuit influences symptom severity in patients with OCD.

Anxiety disorder includes different subtypes such as panic disorder, obsessive-compulsive disorder (OCD), specific phobias, post traumatic stress disorder (PTSD), agoraphobia, social anxiety disorder, and generalized anxiety disorder. The subtypes are categorized depending upon the underlying causative factor. Even though the symptoms of the anxiety disorder subtypes differ slightly, they will certainly have a common characteristic symptom of fear and insecurity. Anxiety disorder manifests both mental as well as physical symptoms. http://www.xanax-effects.com/
