This study determined the prevalence and clinical correlates of all DSM\u2010IV\u2010TR 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,\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.01], higher rates of motor fluctuations [77% (10\/13) vs. 39% (25\/64),\n                    <jats:italic>P<\/jats:italic>\n                    = 0.01] and morning dystonia [38% (5\/13) vs. 13% (8\/62),\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 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. \u00a9 2009 Movement Disorder Society\n                  <\/jats:p>","DOI":"10.1002\/mds.22611","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T16:30:46Z","timestamp":1241713846000},"page":"1333-1338","source":"Crossref","is-referenced-by-count":240,"title":["Prevalence of anxiety disorders and anxiety subtypes in patients with Parkinson's disease"],"prefix":"10.1002","volume":"24","author":[{"given":"Gregory M.","family":"Pontone","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James R.","family":"Williams","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen E.","family":"Anderson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary","family":"Chase","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susanne A.","family":"Goldstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Grill","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elaina S.","family":"Hirsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Lehmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John T.","family":"Little","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell L.","family":"Margolis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter V.","family":"Rabins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Howard D.","family":"Weiss","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Marsh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,5,7]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2004.00781.x"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.147.2.217"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870080415"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.59.3.408"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.parkreldis.2007.06.011"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1176\/jnp.16.1.29"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0006-3223(93)90237-8"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.145.8.1020"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.64.12.1385"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(200007)15:4<669::AID-MDS1011>3.0.CO;2-5"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.22233"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.55.3.181"},{"key":"e_1_2_7_14_2","volume-title":"Structured clinical interview for DSM\u2010IV\u2010TR axis I disorders, research version, patient edition.
