Prevalence of anxiety disorders and anxiety subtypes in patients with Parkinson’s disease.

Department of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine, Baltimore, Maryland 21287, USA.

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. 2009 Movement Disorder Society.

Dizziness: anxiety, health care utilization and health behavior–results from a representative German community survey.

Clinic of Psychosomatic Medicine and Psychotherapy, Johannes Gutenberg-University Mainz, Germany.

BACKGROUND: Due to the lack of epidemiological data on the relation of dizziness and anxiety, we investigated the prevalence of dizziness and anxiety in a representative sample of the German population. We explored the consequences of comorbid anxiety for emotional distress, functional impairment, health care utilization, and health behavior in dizziness. METHODS: By the end of 2006, we surveyed a total of 1287 persons between 14 and 90 years of age in their homes by trained interviewers with standardized self-rating questionnaires on anxiety (Patient Health Questionnaire, Generalized Anxiety Disorder Scale, Mini-Social Phobia Inventory) and dizziness (Vertigo Symptom Scale). The sample was representative for the German population in terms of age, sex, and education. RESULTS: Symptoms of dizziness were reported by 15.8% of the participants. Of the participants with dizziness, 28.3% reported symptoms of at least one anxiety disorder (generalized anxiety, social phobia, panic). Persons with dizziness reported more somatic problems such as hypertension, migraine, diabetes, etc. Comorbid anxiety was associated with increased health care use and impairment. CONCLUSION: Dizziness is a highly prevalent symptom in the general population. A subgroup with comorbid anxiety is characterized by an increased subjective impairment and health care utilization due to their dizziness. Because treatment options for distinct neurotologic disorders are also known to reduce psychological symptoms, and in order to avoid unnecessary medical treatment, early neurologic and psychiatric/psychotherapeutic referral may be indicated.

Non-fearful panic disorder in gastroenterology.

Unità di Psicosomatica, IRCCS Ospedale De Bellis, Via della Resistenza, 70013 Castellana Grotte, Bari, Italy. porcellip@media.it

BACKGROUND: Nonfearful panic disorder (NFPD) is a panic condition masked under the appearance of somatic symptoms only, without the component of fear, and it represents a challenging diagnostic task. METHOD: This is the first case report of NFPD in a male patient with acute gastric pain and gastrointestinal disease (atrophic gastritis and H. pylori infection). RESULTS: The patient showed atypical panic symptoms and demoralization on the Diagnostic Criteria for Psychosomatic Research screening. He was successfully treated with anti-panic medication and cognitive-behavioral therapy. DISCUSSION: The case report shows that accurate psychosomatic assessment may help clinicians avoid diagnostic delay, prevent the administration of unnecessary medications, and give patients more appropriate treatment.

Pain interference impacts response to treatment for anxiety disorders.

Department of Psychiatry, University of Pittsburgh, Pittsburgh, Pennsylvania, USA. tehc@upmc.edu

BACKGROUND: Anxiety disorders and pain are commonly comorbid, though little is known about the effect of pain on the course and treatment of anxiety. METHODS: This is a secondary analysis of a randomized controlled trial for anxiety treatment in primary care. Participants with panic disorder (PD) and/or generalized anxiety disorder (GAD) (N=191; 81% female, mean age 44) were randomized to either their primary-care physician’s usual care or a 12-month course of telephone-based collaborative care. Anxiety severity, pain interference, health-related quality of life, health services use, and employment status were assessed at baseline, and at 2-, 4-, 8-, and 12-month follow-up. We defined response to anxiety treatment as a 40% or greater improvement from baseline on anxiety severity scales at 12-month follow-up. RESULTS: The 39% who reported high pain interference at baseline had more severe anxiety (mean SIGH-A score: 21.8 versus 18.0, P<.001), greater limitations in activities of daily living, and more work days missed in the previous month (5.8 versus 4.0 days, P=.01) than those with low pain interference. At 12-month follow-up, high pain interference was associated with a lower likelihood of responding to anxiety treatment (OR=.28; 95% CI=.12-.63) and higher health services use (26.1% with >/=1 hospitalization versus 12.0%, P<.001). CONCLUSIONS: Pain that interferes with daily activities is prevalent among primary care patients with PD/GAD and associated with more severe anxiety, worse daily functioning, higher health services use, and a lower likelihood of responding to treatment for PD/GAD.
