Long-term outcomes after reversible cerebral vasoconstriction syndrome:

BackgroundLong-term outcomes of reversible cerebral vasoconstriction syndrome (RCVS) have not been systematically investigated.MethodsThe following validated questionnaires were mailed to patients recruited from the RCVS registries of two academic hospitals: headache screening form, Headache Impact Test, Migraine Disability Assessment Test, Barthel Index (BI), EuroQoL (EQ-5D-5L) and Patient Health Questionnaire (PHQ-9).ResultsOf the 191 patients in the registries, 109 could be contacted and 45 responded.
