CVS is a debilitating illness with frequent attacks of prolonged duration. There is a high association with anxiety/depression as well as headaches. Antimigraine medication, β-blockers and antiepileptic treatment may be successful at attenuating attacks; however, in this long-term study, the prognosis of patients not treated with these medications was also good. Overall, 61.9% of patients showed a gradual improvement in symptoms and 23.8% had complete resolution after a mean of 7 years.
