Major Neurocognitive Disorder is defined by significant cognitive decline in one or more domains and interference in daily living.

• A. Significant cognitive decline with interference in daily living
• B. Mild memory loss with full independence
• C. Not cognitive decline
• D. Only language impairment that does not affect daily living

Answer: (A)

The thing this item is testing is the threshold for Major Neurocognitive Disorder. To meet this diagnosis, there must be a substantial decline in one or more cognitive domains that is severe enough to interfere with independence in daily activities. In other words, the person not only shows noticeable cognitive problems but also cannot carry out everyday tasks (like managing finances, cooking, or safely handling personal care) without assistance.

This is what separates Major Neurocognitive Disorder from milder forms: milder forms involve cognitive change but do not disrupt daily independence. The other options describe scenarios with either no cognitive decline, no impact on daily living, or a domain-specific impairment (like language) that does not affect daily functioning, so they do not fit the criteria for major.
