Is the weather a trigger for reversible cerebral vasoconstriction syndrome?

Takeaway

  • Reversible cerebral vasoconstriction syndrome (RCVS) is triggered by low temperature, low rainfall and high barometric pressure in a Taiwanese population.

Why this matters

  • RCVS carries risk for life-threatening complications – new findings shed light on an important triggering factor ­– weather – which could aid in predicting RCVS patterns.
