While North America remains the leader in delirium research spending, the Delirium Market region focus is shifting toward Japan and Western Europe. In 2026, Japan’s "Super-Aged" status means that over 30% of their hospital beds are occupied by patients at high risk for delirium. This has led to the world’s first national "Delirium Prevention Mandate."

In emerging markets like Brazil and India, the focus is on "Post-Surgical Delirium" in the growing middle-class elective surgery segment. As these regions expand their private hospital networks, the demand for standardized delirium screening software is skyrocketing. Navigating these regional dynamics requires vendors to offer scalable, low-cost digital screening tools that can be integrated into the diverse Electronic Medical Record (EMR) systems found across the globe.
