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).

Rigid Hollow Microparticles for Enhanced Focused Ultrasound Treatment Under Optoacoustic Guidance

Advanced Science, EarlyView.
By combining focused ultrasound (FUS) and acoustically active hollow borosilicate microparticles (HBMPs), we demonstrate tunable control over interparticle dynamics and their localized thermal energy deposition. Modulation of acoustic frequency and particle concentration tailors the energy delivery, allowing adaptive, material‐based regulation of ...

Profiling functional networks identify activation of corticostriatal connectivity in ET patients after MRgFUS thalamotomy

NeuroImage: Clinical
Background: MR-guided focused ultrasound (MRgFUS) thalamotomy is a novel and effective treatment for medication-refractory tremor in essential tremor (ET), but how the brain responds to this deliberate lesion is not clear.

Probabilistic Lesion Mapping to Optimize Thalamotomy Targets for Focal Hand Dystonia

Annals of Neurology, EarlyView.
Objective Focal hand dystonia (FHD) severely impairs task‐specific motor control, yet the optimal surgical target for stereotactic intervention remains uncertain. This study aimed to identify the precise thalamic lesion site associated with symptomatic improvement and to clarify its network connectivity. Methods We retrospectively analyzed 164 patients

Making a Difference—Positive Effect of Unilateral VIM Gamma Knife Thalamotomy in the Therapy of Tremor in Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS)

Frontiers in Neurology, 2018
Fragile X Tremor Ataxia Syndrome (FXTAS) is a syndrome based on expansion of the repeats of CGG triplets. The symptoms include action tremor and cerebellar gait ataxia.

Ethnic and Gender Disparities in Access to Deep Brain Stimulation Surgery for Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Deep brain stimulation (DBS) is an established treatment for Parkinson's disease (PD) in appropriately selected patients. DBS may be underused in certain patient populations, especially women and racialized groups. Barriers and biases to receiving DBS that could account for underuse among these groups are not well studied in Canada.

Managing Dystonia in Partington Syndrome

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Bilateral focal hand dystonia is an almost pathognomonic sign of Partington syndrome, frequently accompanied by intellectual disability and oromotor dyspraxia. However, a few studies have focused on the treatment of this focal dystonia, making patient management uncertain.

Investigating Sleep Concerns in Cervical Dystonia

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Heterogenous, small cohorts, and co‐occurrence of pain and psychiatric burden complicate understanding of sleep in dystonia. Objective To investigate sleep concerns in cervical dystonia (CD). Methods Longitudinal data from CD‐PROBE on subjects who were toxin‐naïve, new to practice, or without injections for at least 16 weeks were ...

Ocular Motor Abnormalities in Functional Neurological Disorder: A Video‐Oculography Study

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Functional neurological disorders (FND) can include various sensory, motor or cognitive symptoms. Eye movement recordings, measured through video‐oculography, could serve as biomarkers for characterizing these dysfunctions in FND.
