Answer is yes ,it can diagnose before they rupture. AVM can produce head ache ,seizures and at time with weakness, visual symptoms etc . Some times found often a brain scan for another brain issue

Thank you doctor

Usually diagnosed after rupture and hemorrhage. Accidentally it can be diagnosed while treating or diagnosing another disease
