Blink reflex as a complementary test to MRI in early detection of brainstem infarctions: comparison of blink reflex abnormalities in anterior versus posterior circulation strokes

ABSTRACT

Background: early detection of vertebro-basilar insufficiency is of paramount importance. Brain MRI was the only method of diagnosis for many years, but in addition to high cost and delay in report, it may not detect all brain stem lesions. In this study Blink reflex [BR] was evaluated as a complementary test to MRI
