Which symptom distinguishes major neurocognitive disorders from mild ones?

A. Slight disorientation in familiar places is more indicative of mild neurocognitive disorder. Individuals may occasionally get lost or confused but can generally navigate familiar environments with minimal assistance. This symptom alone does not signify a major impairment in independence. B. Occasional forgetfulness is common in normal aging or mild neurocognitive disorder. Examples include misplacing items or forgetting appointments occasionally. These lapses are not severe enough to interfere with essential daily activities, distinguishing them from major neurocognitive disorder. C. Difficulty with single tasks may appear in mild neurocognitive disorder when concentration, attention, or executive function is slightly impaired. While concerning, this symptom typically does not prevent the individual from completing everyday activities independently. D. Significant memory retrieval issues are a hallmark of major neurocognitive disorder. Clients may experience frequent inability to recall important personal events, difficulty recognizing familiar people or places, and substantial challenges performing routine or complex daily tasks independently. These impairments interfere with work, self-care, and social functioning, which is the key criterion that differentiates major from mild neurocognitive disorders.
