What is defined as a serious disturbance in mental abilities resulting in confused thinking?

Delirium is characterized by a rapid onset of confusion and disorientation, often impacting a person's cognitive functions such as attention, memory, and perception. This state can result from various factors, including medical conditions, medications, or substance withdrawal. The hallmark of delirium is the fluctuation in consciousness and the presence of disturbed thoughts, making it distinct from other mental health disorders like depression, schizophrenia, or bipolar disorder, which involve more chronic patterns of mood or thought disturbances. Recognizing delirium is crucial, especially in a jail setting, because it can indicate underlying medical issues requiring immediate attention or intervention.
