Which of the following is NOT a common cause of Delirium?

Chronic hypertension is not commonly recognized as a direct cause of delirium. Delirium is typically characterized by an acute disturbance in attention and cognition, and its causes often include factors that lead to sudden changes in mental status. Infections, heavy metals, and acute vascular shock can all precipitate delirium through mechanisms such as metabolic imbalances, toxicity, or reduced cerebral perfusion.

Infections, like urinary tract infections or pneumonia, can lead to systemic inflammation and metabolic changes that trigger delirium. Heavy metal exposure, such as lead or mercury, can also result in toxicity that affects the brain and causes cognitive disturbances. Acute vascular shock refers to conditions such as sepsis or significant blood loss, which can reduce blood flow to the brain and lead to confusion or altered mental states.

On the other hand, while chronic hypertension can have long-term effects on brain health and might increase the risk of cognitive decline or vascular dementia, it does not typically result in the acute, fluctuating symptoms characteristic of delirium. This distinction is crucial in understanding the causes and appropriate management of delirium in clinical settings.
