Neurological complications in reversible cerebral vasoconstriction syndrome: what are the risk factors?


  • In patients with reversible cerebral vasoconstriction syndrome (RCVS), the absence of thunderclap headache (TCH) at onset was associated with a higher risk of neurological complications.

Why this matters

  • RCVS is a rare condition causing sudden, severe headaches as a result of multisegmental cerebral vasoconstriction. It typically presents with TCH.

  • Identification of risk factors for neurological complications, which can occur in up to 79% of patients, will aid in the clinical management of patients with RCVS.
