Brissau Reflex, SYNDROMES. Brissau reflex - contraction of the m. tens. fasc. latae when the sole is stroked. The reflex is normal, and the reflex arc corresponds to the V lumbar and I-II sacral segments. - Brissau-Marie syndrome (Marie), hemispasmus glosso-labialis, is observed in hysteria: the mouth and tongue are pulled to the same side, and the jaw may also be displaced in that direction; sometimes the m. orbicularis orbitae also participates in the spasm. This symptom complex is also characteristic of organic hemiplegia. For differential diagnosis, it is significant that in organic hemiplegia, the mouth is pulled to the healthy side, while the tongue is pulled to the paralyzed side; in the Brissau-Marie symptom complex, both the mouth and tongue are pulled to the same side. - Brissau-Sicard syndrome, see Alternating syndromes.
