What is the essential feature of Delirium according to the DSM-5?

Impaired ability to transfer information from short- to long-term memory
A disturbance in attention and awareness
A disturbance in psychomotor behavior
Disorientation

The correct answer is: A disturbance in attention and awareness

The essential feature of Delirium, as defined by the DSM-5, is a disturbance in attention and awareness. This is pivotal because Delirium is characterized by a sudden onset and fluctuating course, leading to a reduced ability to focus, sustain, or shift attention. Additionally, individuals with Delirium may experience confusion about their surroundings, which reinforces the connection between impaired attention and disordered awareness. While other features such as disorientation, disturbances in psychomotor behavior, or memory impairments may accompany Delirium, they are not in themselves the defining characteristic. The hallmark of Delirium is primarily the significant change in cognitive function, with attention impairment being the most consistent and critical symptom that differentiates it from other cognitive disorders. Understanding this central aspect aids in recognizing, diagnosing, and appropriately treating individuals affected by Delirium.
