Imaging Features of Hypertrophic Olivary Degeneration
Journal of the Belgian Society of Radiology, 2016 Hypertrophic olivary degeneration (HOD) is a unique form of transneuronal degeneration caused by a disruption of the dentato-rubro-olivary pathway, also known as the triangle of Guillain-Mollaret.

A 6-month trial of memantine for nystagmus and associated phenomena in oculopalatal tremor
Frontiers in Neurology, 2022 IntroductionOculopalatal tremor (OPT) is a late manifestation of a Guillain-Mollaret triangle lesion. Memantine has been shown to improve nystagmus in OPT, but its long-term efficacy and putative distinct effects on each plane of nystagmus and on ...
