Which of the following is not a differential diagnosis of heatstroke?

The rationale for choosing this specific option is grounded in the presentation and underlying mechanisms of heatstroke compared to other conditions. Heatstroke typically occurs due to prolonged exposure to high temperatures, leading to hyperthermia and organ dysfunction. The differential diagnoses for heatstroke often include conditions that present with similar symptoms, particularly those associated with altered mental status and hyperthermia.

Cerebrovascular accidents, central nervous system (CNA) infections, and diabetic ketoacidosis can all result in altered mental status and may be associated with significant bodily stress, which can overlap in symptoms with heatstroke. For instance, a cerebrovascular accident may produce neurological symptoms similar to those seen in heatstroke due to impaired blood flow or swelling in the brain, while CNS infections can also cause fever and confusion in addition to other systemic effects.

In contrast, alcohol intoxication, while it does affect the central nervous system and can lead to altered mental status, does not typically produce hyperthermia at the same severity or pathophysiological level as heatstroke. While alcohol can precipitate changes in body temperature, it does not produce the life-threatening hyperthermia characteristic of heatstroke. Therefore, it is less likely to be considered a direct differential diagnosis for heatstroke when compared to the
