Detailed descriptions of the syndromes are therefore lacking. The neuroanatomical basis of restlessness may consist of abnormalities in the corticc-subcortical neuronal circuits, the complex regulation of which may explain why different causes often lead to a common end result.<\/jats:p>\n                  <jats:p>Conclusions: The terms used to describe restlessness and related disorders should be standardised, and the clinical manifestations investigated pedanti- cally. Human and animal studies should investigate the pathophysiology so that intervention can be based on the underlying mechanisms.<\/jats:p>","DOI":"10.3109\/00048679609076071","type":"journal-article","created":{"date-parts":[[2007,11,21]],"date-time":"2007-11-21T20:55:18Z","timestamp":1195678518000},"page":"38-53","source":"Crossref","is-referenced-by-count":23,"title":["Restlessness: The Anatomy of a Neuropsychiatric Symptom"],"prefix":"10.1177","volume":"30","author":[{"given":"Perminder","family":"Sachdev","sequence":"first","affiliation":[{"name":"Neuropsychiatric Institute, Prince Henry Hospital, PO Box 233, Matraville, New South Wales"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane","family":"Kruk","sequence":"additional","affiliation":[{"name":"Neuropsychiatric Institute, Prince Henry Hospital, PO Box 233, Matraville, New South Wales"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1996,2,1]]},"reference":[{"key":"bibr1-00048679609076071","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.80.329.277"},{"key":"bibr2-00048679609076071","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.138.1.1"},{"key":"bibr3-00048679609076071","first-page":"100","volume":"49","author":"Pohl R","year":"1988","journal-title":"Journal of Clinical Psychiatry"},{"key":"bibr4-00048679609076071","first-page":"704","volume":"17","author":"Haskovec L.","year":"1902","journal-title":"Archives Boh\u00e8mes M\u00e9dicine Clinique"},{"key":"bibr5-00048679609076071","volume-title":"The concise Oxford dictionary of current English","author":"Sykes JB.","year":"1994"},{"key":"bibr6-00048679609076071","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-6494.1986.tb00402.x"},{"key":"bibr7-00048679609076071","unstructured":"Hamilton M.
