Altered Mental Status (AMS) refers to a change in a person's awareness, cognition, or behavior. This condition can manifest as confusion, disorientation, or decreased responsiveness. AMS can result from various factors, including medical conditions, substance use, or infections. Common causes of AMS include stroke, seizures, hypoxia, and medications. It is essential to identify the underlying cause to provide appropriate treatment. Healthcare professionals often assess AMS through physical examinations and diagnostic tests to determine the best course of action for the affected individual.
