Description
Delirium is a common and serious problem among acutely unwell persons. Although linked to higher rates of mortality, institutionalization and dementia, it remains under diagnosed. Careful consideration of its phenomenology is warranted to improve detection and therefore mitigate some of its clinical impact. The publication of the fifth edition of the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM- 5) provides an opportunity to examine the constructs underlying delirium as a clinical entity [1]. We are reporting a case of delirium in a 20 years old female that was precipitated by a secondary polycythaemia caused by a congenital cardiac left to right shunt resulting in a pulmonary hypertension. Our med pub mesh literature search did not yield a previously reported similar case.
