Reversible cerebral vasoconstriction syndrome: a clinical and therapeutic challenge

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headache and intracranial segmental vasoconstriction with or without signs of neurological deficit with a variable course that requires extensive study to prevent complications. The evidence shows RCVS is characterized by being multi-etiological; both the cause and the specific symptoms must be treated to reduce the chance of complications and recurrence. The timely identification of the RCVS and its etiology is the cornerstone of success in managing the disease. New data must be generated to have more efficient resources for the approach to this disease.
