Common Neurological Alterations of the
Dentato-Rubro-Olivary Pathway (Guillain Mollaret Triangle) in Different Pathological Fields : From Palatal
Myoclonus to Sudden Unexplained Fetal and Infant Death - A Possible Interpretation / A.M. Lavezzi, G. Farronato, M.A. Mauri, F. Santoro, L. Matturri. - In: EUROPEAN NEUROLOGICAL JOURNAL. - ISSN 2041-8000. - 3:1(2011 Jul), pp. 8-14.
Abstract:
We discussed the anatomy and the developmental alterations of a neuronal circuit, already implied in the pathogenesis of the
palatal myoclonus, and connecting the dentate nucleus in the cerebellum with the red nucleus and the inferior olivary nucleus in the
brainstem, in the context of our findings obtained in a wide set of sudden intrauterine unexplained death (SIUD) and sudden infant death
syndrome (SIDS). We observed high incidence of developmental alterations (hypoplasia, hyperplasia, and high c-fos neuronal
immunopositivity) of the three nuclei in both SIDS and SIUD, frequently associated to serotonergic abnormalities and to maternal smoking
in pregnancy. We underlined the likeness of these neurological abnormalities with the neuropathologic picture marking the palatal
myoclonus. We concluded that the network connecting the dentate, the red, and the inferior olivary nuclei is involved in the pathogenesis
of a wide spectrum of manifestations, which, even if quite different, can be ascribed to a defective muscular contraction, frequently triggered
from hypoxic conditions. Wrong contraction of eye, face, and throat muscles can lead to palatal myoclonus; wrong contracture of the
upper airway muscles can be involved in the pathogenetic mechanism of the sudden fetal death and sudden infant death in the first months
of life.
