Abstract
Psychiatric disorders are highly prevalent in patients with dystonia and have a profound effect on quality of life. Patients with dystonia frequently meet criteria for anxiety disorders, especially social phobia, and major depressive disorder. Deficits in emotional processing have also been demonstrated in some dystonia populations. Onset of psychiatric disturbances in patients with dystonia often precedes onset of motor symptoms suggesting that the pathophysiology of dystonia itself contributes to the genesis of psychiatric disturbances. This article examines the hypothesis that mood and anxiety disorders are intrinsic to the neurobiology of dystonia, citing the available literature, which is derived mostly from research on focal isolated dystonias. Limitations of studies are identified and the role of emotional reactivity, especially in the context of pain secondary to dystonia, is recognized. Available evidence underscores the need to develop dystonia assessment tools that incorporate psychiatric measures. Such tools would allow for a better understanding of the full spectrum of dystonia presentations and facilitate research on the treatment of dystonia as well as the treatment of psychiatric illnesses in the context of dystonia.
