Understanding Delirium: Primary Causes and Risk Factors

Introduction

Delirium is a complex syndrome characterized by acute confusion, fluctuations in mental status, and altered consciousness. It often develops rapidly and can have serious implications for patient care, especially in hospital settings. Understanding the primary causes and risk factors associated with delirium is vital for prevention and management.
