Diagnostic challenges in the older patient

<p>Abstract</p> <p>Older patients often present with a long, complex history and a clinical picture that frequently includes co-morbidities. It is essential that health professionals caring for older patients become familiar with common age-related changes, and the specific clinical factors that complicate the diagnostic process. A case-based approach is taken in this article to explore the diagnostic challenges in caring for older patients. Three areas of focus are used: a) polypharmacy, b) cognitive issues such as delirium, dementia and depression, and c) increased odds of pathologies and chronic illnesses.</p
