Which of the following scenarios best describes a mild neurocognitive disorder?

Rationale: A. This scenario reflects major neurocognitive disorder (dementia), where cognitive deficits are severe enough to significantly impair independence in daily functioning. It is beyond the mild stage. B. Mild neurocognitive disorder is characterized by modest cognitive decline that is noticeable but does not significantly interfere with independence in daily activities. Patients may require some support with complex or unfamiliar tasks, but basic self-care and routine activities are preserved. This scenario accurately depicts mild neurocognitive disorder. C. Cognitive changes secondary to depression (pseudodementia) are not classified as neurocognitive disorder because the cognitive deficits improve with treatment of the underlying mood disorder. D. Acute confusion represents delirium, a temporary and reversible cognitive impairment caused by an identifiable medical or pharmacologic trigger. It is not considered a neurocognitive disorder.
