Final answer:
The correct option is (B). The false statement about delirium is that it is irreversible. Delirium is typically reversible and characterized by rapid development, attention disturbance, and increased prevalence with age.
Step-by-step explanation:
The statement that is false about delirium is: It is irreversible. Delirium is indeed an acute cognitive disorder that is typically reversible and is characterized by a disturbance in attention, along with other cognitive impairments. It often develops rapidly, over hours or a few days, and the prevalence rates of delirium do tend to rise with age, especially among those who are hospitalized or in long-term care facilities.
Common symptoms of delirium can include disruptive memory loss, confusion about time or place, difficulty with planning and executing tasks, poor judgment, and personality changes. However, these symptoms are often mistaken for dementia, which typically involves more progressive memory loss and cognitive decline and can include symptoms like slowed movements, rigid muscles, and speech changes. Unlike delirium, dementia usually develops slowly and is often irreversible once it has progressed to a certain stage.
