Hierarchical Dynamic Causal Modeling of Resting-State fMRI Reveals Longitudinal Changes in Effective Connectivity in the Motor System after Thalamotomy for Essential Tremor

Frontiers in Neurology, 2017
Thalamotomy at the ventralis intermedius nucleus for essential tremor is known to cause changes in motor circuitry, but how a focal lesion leads to progressive changes in connectivity is not clear. To understand the mechanisms by which thalamotomy exerts

Connectomic Basis for Tremor Control in Stereotactic Radiosurgical Thalamotomy

American Journal of Neuroradiology, 2023
Stereotactic radiosurgical targets with a distinct connectivity profile predict improvement in tremor after treatment. Such connectomic fingerprints show promise for developing patient-specific biomarkers to guide therapy with stereotactic radiosurgical ...

The Relevance of Intraoperative Clinical and Accelerometric Measurements for Thalamotomy Outcome

Journal of Clinical Medicine, 2023
Thalamotomy alleviates medication-refractory tremors in patients with movement disorders such as Parkinson’s Disease (PD), Essential tremor (ET), and Holmes tremor (HT). However, limited data are available on tremor intensity during different thalamotomy

Target identification for stereotactic thalamotomy using diffusion tractography. [PDF]

PLoS ONE, 2012
BACKGROUND: Stereotactic targets for thalamotomy are usually derived from population-based coordinates. Individual anatomy is used only to scale the coordinates based on the location of some internal guide points.

Magnetic resonance imaging–guided focused ultrasound thalamotomy for essential tremor: 5-year follow-up results

Journal of Neurosurgery, 2022
In Brief Researchers examined the 5-year clinical outcomes of patients with medically refractory essential tremor (ET) who had previously undergone MRI-guided focused ultrasound (MRgFUS) thalamotomy in a randomized, blinded, sham-controlled trial ...

The variation of functional connectivity and activity before and after thalamotomy surgery (review)

Frontiers in Human Neuroscience, 2023
Ablation surgeries are utilized to treat certain brain disorders. Recently, these surgeries have become more prevalent using techniques such as magnetic resonance guided focused ultrasound (MRgFUS) ablation and Gamma knife thalamotomy (GKT).

The Optimal Targeting for Focused Ultrasound Thalamotomy Differs between Dystonic and Essential Tremor: A 12‐Month Prospective Pilot Study

Movement Disorders Clinical Practice, 2023
Magnetic resonance‐guided focused ultrasound (MRgFUS) thalamotomy is increasingly used to treat drug‐resistant essential tremor (ET). Data on MRgFUS thalamotomy in dystonic tremor (DT) are anecdotal.

Focused ultrasound thalamotomy for tremor treatment impacts the cerebello-thalamo-cortical network

npj Parkinson's Disease, 2023
High-intensity Magnetic Resonance-guided Focused Ultrasound (MRgFUS) is a recent, non-invasive line of treatment for medication-resistant tremor. We used MRgFUS to produce small lesions in the thalamic ventral intermediate nucleus (VIM), an important ...
