1. Major NCD involves disorientation that develops suddenly, whereas mild NCD develops more slowly.
2. Major NCD involves impairment of abstract thinking and judgment, whereas mild NCD does not.
3. Major NCD criteria requires substantial cognitive decline from a previous level of performance, and mild NCD requires modest decline.

Rationale: The progression of the disorder is not a criterion for determining the severity of an NCD. Abstract thinking and judgment can be affected in both mild NCD and major NCD. Major NCD criteria requires substantial cognitive decline, and mild NCD requires modest decline. Both major and mild NCD classifications require decline from a previous level of performance in only one of the listed domains.
