Hypertrophic degeneration of the inferior olivary nucleus impacts perception of gravity

Frontiers in Neurology, 2012
Interruption of the Guillain-Mollaret triangle interconnecting the red nucleus, the inferior olivary nucleus and the contralateral dentate nucleus is predicted to interfere with the dentate nucleus’ role in estimating direction of gravity.

Qualitative and quantitative detectability of hypertrophic olivary degeneration in T2, FLAIR, PD, and DTI: A prospective MRI study

Frontiers in Neurology, 2022
Purpose:Hypertrophic olivary degeneration (HOD) is a pathology of the inferior olivary nucleus (ION) that occurs after injuries to the Guillain-Mollaret triangle (GMT). Lacking a diagnostic gold standard, diagnosis is usually based on T2 or FLAIR imaging

Diffusion tensor imaging in orthostatic tremor: a tract‐based spatial statistics study

Annals of Clinical and Translational Neurology, Volume 6, Issue 11, Page 2212-2222, November 2019., 2019
Abstract Objective The pathogenesis of orthostatic tremor (OT) is unknown. We investigated OT‐related white matter changes and their correlations with scores from a neuropsychological testing battery. Methods Diffusion tensor imaging measures were compared between 14 OT patients and 14 age‐ and education‐matched healthy controls, using whole‐brain ...

Essential Palatal Tremor Managed by Cognitive Behavioral Therapy

Case Reports in Dentistry, Volume 2015, Issue 1, 2015., 2015
Background. Essential palatal tremor is a disorder of unknown etiology involving involuntary movement of the uvula and soft palate. Treatment attempts including drugs or surgery have been conducted to cease the rhythmical movement. Case Report. A 55‐year‐old female visited our department complaining of a sudden, noticeable, intermittent, and rhythmical

Feasibility of Endoscopic Treatment of Middle Ear Myoclonus: A Cadaveric Study

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
Stapedius and tensor tympani tenotomy is a relatively simple surgical procedure commonly performed to control pulsatile tinnitus due to middle ear myoclonus and for several other indications. We designed a cadaveric study to assess the feasibility of an entirely endoscopic approach to stapedius and tensor tympani tenotomy.

Multicenter Prospective Analysis of Hypertrophic Olivary Degeneration Following Infratentorial Stroke (HOD-IS): Evaluation of Disease Epidemiology, Clinical Presentation, and MR-Imaging Aspects

Frontiers in Neurology, 2021
Introduction: Ischemic and hemorrhagic strokes in the brainstem and cerebellum with injury to the functional loop of the Guillain-Mollaret triangle (GMT) can trigger a series of events that result in secondary trans-synaptic neurodegeneration of the ...

Treatment of Palatal Myoclonus with Botulinum Toxin Injection

Case Reports in Otolaryngology, Volume 2013, Issue 1, 2013., 2013
Palatal myoclonus is a rare cause of pulsatile tinnitus in patients presenting to the otolaryngology office. Rhythmic involuntary contractions of the palatal muscles produce the pulsatile tinnitus in these patients. Treatment of this benign but distressing condition with anxiolytics, anticonvulsants, and surgery has been largely unsuccessful.

Hypertrophic Olivary Degeneration and Holmes' Tremor Secondary to Bleeding of Cavernous Malformation in the Midbrain

Tremor and Other Hyperkinetic Movements, 2014
Background: Hypertrophic olivary degeneration (HOD) is a rare phenomenon, probably related to transsynaptic degeneration of the inferior olivary nucleus.

Hypertrophic olivary degeneration: A case report

Indian Journal of Radiology and Imaging, 2019
Hypertrophic olivary degeneration is a rare occurrence in which different pathological processes including enlargement and vacuolation of the neurons, demyelination of the white matter, and fibrillary gliosis of the inferior olivary nucleus take place ...

Brain Imaging Phenotypes Associated with Polygenic Risk for Essential Tremor

Movement Disorders, Volume 40, Issue 6, Page 1160-1171, June 2025.
Abstract Essential tremor (ET) is a common movement disorder with a strong genetic basis. Magnetic resonance imaging (MRI), particularly diffusion‐weighted MRI (dMRI) and T1 MRI, have been used to identify brain abnormalities of ET patients. However, the mechanisms by which genetic risk affects the brain to render individuals vulnerable to ET remain ...
