[Electrologic syndromes of alteration of elicited blink reflex in multiple sclerosis. Study of a group of 33 patients (author's transl)].
The study of the blink reflex, performed in a group of 33 patients with multiple sclerosis show, as Kimura (1970) and Namerow (1973) had established, the high frequency of its alterations in this disease (almost half of the cases). The alterations of blink reflex don't depend on duration of illness; if it is true that the alterations of blink reflex are more often observed in patients with clinical symptoms of involvement of brain-stem (and particularly of pons), in some cases, only the alteration of the blink reflex suggests a brain-stem's lesion and helps to establish the diagnosis. The diversity of sites of lesions induced by multiple sclerosis in the brain-stem explains the diversity of blink reflex alteration's syndromes since they correspond to the (almost) totality of the semiology of blink reflex.
