Final answer:
Delirium is characterized by a rapid onset of symptoms, while major neurocognitive disorder, such as Alzheimer's Disease, has a gradual onset with symptoms worsening over time.
Step-by-step explanation:
The student is asking about the onset characteristics of delirium and major neurocognitive disorder. Delirium has a rapid onset, characterized by disruptive memory loss, confusion about time or place, difficulty with planning and executing tasks, poor judgment, and/or personality changes. In contrast, major neurocognitive disorder, such as Alzheimer's Disease (AD), has a gradual onset. AD is a progressive neurodegenerative disease where brain damage becomes more extensive over time, leading to symptoms such as slowed movements, balance and posture problems, and cognitive disruption like dementia.
Neurological deficits can be caused by infection, trauma, strokes, or congenital disorders. Injuries can result in symptoms like an inability to move or feel on one side of the body, speech difficulties, and confusion. The mental status exam helps differentiate between acute and chronic conditions, looking at the extent and type of neurological damage.
In summary, for the provided options, the appropriate answers are: Delirium has a rapid onset, and major neurocognitive disorder has a gradual onset.
