In the human peripheral cells of patients with anxiety disorders and in animal models of anxiety disorders, genes such as GAD1, NR3C1, BDNF, MAOA, HECA, and FKBP5 are shown to be hypermethylated. As such, the mechanism of action of HDACi in anxiety disorders could, in part, be potentially explained by the demethylation of those genes.

The SIAS discriminates between social anxiety and general anxiety as it has low associations with trait anxiety (a level of stress associated with an individual personality) and general distress. [8] Beyond identifying those who experience social anxiety of some form, the scale can discriminate within the social anxiety class as well. [ 1 ]
A diverse range of topics are covered as they relate to anxiety disorders and is inclusive of disorders that were previously categorized as anxiety related disorders (obsessive-compulsive disorder, posttraumatic stress disorder) in addition to the new category of illness anxiety disorder.
A number of researchers have explored HADS data to establish the cut-off points for caseness of anxiety or depression. Bjelland et al (2002) [3] through a literature review of a large number of studies identified a cut-off point of 8/21 for anxiety or depression. For anxiety (HADS-A) this gave a specificity of 0.78 and a sensitivity of 0.9.
