Several studies have reported raised levels of psychopathology based on self-rating scales in patients with spasmodic torticollis. Recent publications have also proposed that psychopathology, especially symptoms of depression, might be a reaction to dystonia or constitute a nonspecific reaction pattern. To determine the actual frequency of psychiatric disorders, we evaluated 44 patients with spasmodic torticollis (20 female, 24 male; mean age 43.6 years, SD 10.4) using the standard instrument for psychiatric diagnosis in the DSM-III-R (Structured Clinical Interview Schedule, SCID). The SCID permits retrospective diagnosis for most of the major psychiatric disorders, including the time before onset of dystonia. SCID criteria for at least one psychiatric disorder were fulfilled in 65.9% of patients, including both lifetime and current diagnosis. The most frequent diagnostic categories were panic disorder with or without agoraphobia (29.5%), major depressive disorder (25%), substance abuse (13.6%), and obsessive compulsive disorders (6.8%) were diagnosed less frequently. The patient-recalled onset of psychiatric symptoms preceded onset of torticollis symptoms in 43.2% of those investigated.

Anxiety disorders are common in Parkinson's disease (PD), but are not well characterized. This study determined the prevalence and clinical correlates of all DSM-IV-TR anxiety disorder diagnoses in a sample of 127 subjects with idiopathic PD who underwent comprehensive assessments administered by a psychiatrist and neurologist. A panel of six psychiatrists with expertise in geriatric psychiatry and/or movement disorders established by consensus all psychiatric diagnoses. Current and lifetime prevalence of at least one anxiety disorder diagnosis was 43% (n = 55) and 49% (n = 63), respectively. Anxiety disorder not otherwise specified, a DSM diagnosis used for anxiety disturbances not meeting criteria for defined subtypes, was the most common diagnosis (30% lifetime prevalence, n = 38). Compared with nonanxious subjects, panic disorder (n = 13) was associated with earlier age of PD onset [50.3 (12.2) vs. 61.0 (13.7) years, P < 0.01], higher rates of motor fluctuations [77% (10/13) vs. 39% (25/64), P = 0.01] and morning dystonia [38% (5/13) vs. 13% (8/62), P < 0.03]. This high prevalence of anxiety disorders, including disturbances often not meeting conventional diagnostic criteria, suggests that anxiety in PD is likely underdiagnosed and undertreated and refined characterization of anxiety disorders in PD is needed. In addition, certain anxiety subtypes may be clinically useful markers associated with disease impact in PD.
