The major difference that is useful in the diagnosis of major neurocognitive disorder or delirium is that the symptoms of major neurocognitive disorder develop slowly over time, usually over months or years, whereas the symptoms of delirium develop quickly, usually over hours or days. This difference in the onset of symptoms can help clinicians determine which disorder is more likely to be present, as well as guide appropriate treatment planning. Other factors may also be considered in the diagnosis, such as the underlying causes of the symptoms, the severity or nature of the symptoms, and other medical or psychiatric conditions that may be present. However, the difference in the rate of symptom development is one of the most clinically relevant factors in distinguishing between major neurocognitive disorder and delirium.
