Geriatric medicine refers to the medical practices and interventions aimed at ensuring quality of life for elderly people along with the prevention and treatment of diseases and conditions that people are prone to as they age. One of the most significant issues in geriatrics is the prevention and treatment of delirium. Promoting interventions that are designed to maintain the physical and cognitive functioning of aged adults, maximizing patients’ independence, etc. are some of the ways to manage delirium. Aging may cause changes in the effectiveness of drugs and their side effects. Pharmacological constitution and regimen is another important consideration in geriatric medicine. The elderly are particularly prone to polypharmacy. This happens when a patient suffers from multiple disorders and takes over-the-counter drugs and herbal medications. An important area of study is the efficacy of inappropriate medications and dangerous drug interactions.
