We reported an incidence of 8.2 per 100 000 per year in people above the age of 65 in 2002.<\/jats:p>\n                  <jats:p>Aim: Since recent studies have demonstrated a higher incidence, we repeated our study to estimate the current incidence of CSDH amongst people above the age of 65 in North Wales.<\/jats:p>\n                  <jats:p>Design: We used radiological reports to identify patients with CSDH over a 1-year period.<\/jats:p>\n                  <jats:p>Methods: We collected data on demographics, clinical presentations, indications for brain imaging, drug history and 30-day outcome from the case notes and electronic records.<\/jats:p>\n                  <jats:p>Results: The population of North Wales was 687\u2009937 of which 138\u2009325 (20%) were above 65. There were 66 cases of CSDH giving an incidence of 48 per 100 000 per year. Mean age was 81 and there were 32 males and 34 females. Falls and confusion were the commonest indications to request a CT scan (90%). Other indications were drowsiness (9%) and focal neurological deficit (4%). 17 were on antiplatelets and 20 were on warfarin. Ten underwent surgical intervention. At 30 days 28 were discharged, 22 were still in hospital and 16 died.<\/jats:p>\n                  <jats:p>Conclusion: The incidence of CSDH is much higher than previously reported. Reasons include a low threshold for imaging patients with recurrent falls and confusion, increasing use of anti-thrombotics and ageing population. In many older patients CSDH is a marker of underlying co-morbidities rather than a primary event.<\/jats:p>","DOI":"10.1093\/qjmed\/hcw231","type":"journal-article","created":{"date-parts":[[2017,1,9]],"date-time":"2017-01-09T20:50:20Z","timestamp":1483995020000},"page":"375-378","source":"Crossref","is-referenced-by-count":37,"title":["Increasing incidence of chronic subdural haematoma in the elderly"],"prefix":"10.1093","volume":"110","author":[{"given":"V.","family":"Adhiyaman","sequence":"first","affiliation":[{"name":"From the 1Glan Clwyd Hospital, Rhyl, LL18 5UJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Chattopadhyay","sequence":"additional","affiliation":[{"name":"From the 1Glan Clwyd Hospital, Rhyl, LL18 5UJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Irshad","sequence":"additional","affiliation":[{"name":"From the 1Glan Clwyd Hospital, Rhyl, LL18 5UJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Curran","sequence":"additional","affiliation":[{"name":"2Wrexham Maelor Hospital, Wrexham, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Abraham","sequence":"additional","affiliation":[{"name":"2Wrexham Maelor Hospital, Wrexham, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2017,2,14]]},"reference":[{"key":"2026071307102836000_hcw231-B1","first-page":"290","article-title":"Chronic subdural haematoma in the elderly\u2014a North Wales experience","volume":"95","author":"Asghar","year":"2002","journal-title":"J R Soc Med"},{"key":"2026071307102836000_hcw231-B2","doi-asserted-by":"crossref","first-page":"1209","DOI":"10.3171\/2014.9.JNS141550","article-title":"Actual and projected incidence rates for chronic subdural hematomas in United States Veterans Administration and civilian populations","volume":"123","author":"Balser","year":"2015","journal-title":"J Neurosurg"},{"key":"2026071307102836000_hcw231-B3"},{"key":"2026071307102836000_hcw231-B4","doi-asserted-by":"crossref","first-page":"207","DOI":"10.2176\/nmc.32.207","article-title":"Chronic subdural hematoma in elderly people: present status on Awaji Island and epidemiological prospect","volume":"32","author":"Kudo","year":"1992","journal-title":"Neurol Med Chir"},{"key":"2026071307102836000_hcw231-B5","doi-asserted-by":"crossref","first-page":"1731","DOI":"10.3109\/02699052.2012.698364","article-title":"Cerebral atrophy is associated with development of chronic subdural haematoma","volume":"26","author":"Yang","year":"2012","journal-title":"Brain Inj"},{"key":"2026071307102836000_hcw231-B6","doi-asserted-by":"crossref","first-page":"637","DOI":"10.3171\/jns.1981.54.5.0637","article-title":"Chronic subdural hematomas: a review","volume":"54","author":"Markwalder","year":"1981","journal-title":"J Neurosurg"},{"key":"2026071307102836000_hcw231-B7","doi-asserted-by":"crossref","first-page":"544","DOI":"10.1016\/j.ijsu.2013.05.007","article-title":"Bilateral chronic subdural hematoma: what is the clinical significance?","volume":"11","author":"Huang","year":"2013","journal-title":"Int J Surg"},{"key":"2026071307102836000_hcw231-B8","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1016\/j.clineuro.2004.09.015","article-title":"Chronic subdural haematoma: surgical treatment and outcome in 1000 cases","volume":"107","author":"Gelabert-Gonz\u00e1lez","year":"2005","journal-title":"Clin Neurol Neurosurg"},{"key":"2026071307102836000_hcw231-B9","doi-asserted-by":"crossref","first-page":"612","DOI":"10.1016\/j.amjmed.2005.02.022","article-title":"Incidence of intracranial hemorrhage in patients with atrial fibrillation who are prone to fall","volume":"118","author":"Gage","year":"2005","journal-title":"Am J Med"},{"key":"2026071307102836000_hcw231-B10","doi-asserted-by":"crossref","first-page":"2369","DOI":"10.1093\/eurheartj\/ehq278","article-title":"Guidelines for the management of atrial fibrillation: the Task Force for the Management of Atrial Fibrillation of the European Society of Cardiology (ESC)","volume":"31","author":"Camm","year":"2010","journal-title":"Eur Heart J"},{"key":"2026071307102836000_hcw231-B11","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1136\/pmj.78.916.71","article-title":"Chronic subdural haematoma in the elderly","volume":"78","author":"Adhiyaman","year":"2002","journal-title":"Postgrad Med J"},{"key":"2026071307102836000_hcw231-B12","doi-asserted-by":"crossref","first-page":"138","DOI":"10.1111\/j.1532-5415.1995.tb06378.x","article-title":"Do surgical brain lesions present as isolated dementia?
