Emerging Deep Brain Stimulation Targets in the Cerebellum for Tremor.
Cerebellum
January 2025
Department of Neurology, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA, USA.
Deep brain stimulation (DBS) for essential tremor is remarkably effective, leading to over 80% reduction in standardized tremor ratings. However, for certain types of tremor, such as those accompanied by ataxia or dystonia, conventional DBS targets have shown poor efficacy. Various rationales for using cerebellar DBS stimulation to treat tremor have been advanced, but the varied approaches leave many questions unanswered: which anatomic target, stimulation settings, and indications seem most promising for this emerging approach.

However, clinical assessments of oculomotor function lack precision, limiting sensitivity for measuring progression and the ability to detect subtle early signs. Quantitative assessment of eye movements during everyday behaviors such as reading has potential to overcome these limitations and produce functionally relevant measures.

January 2025
Department of Rehabilitation, Maruki Memorial Medical and Social Welfare Center, Saitama, Japan.
Background: Evidence of the effectiveness of physiotherapy, including muscle strength training, coordination training, aerobic exercise, cycling regimen, balance training, gait training, and activity of daily living training, in patients with degenerative cerebellar ataxia (DCA) was insufficient for clinical decision making. We aimed to explore clinical outcomes and examine the parameters associated with physical impairment and activity in people with DCA based on preregistration (PROSPERO: CRD42024493883).
Methods: The PubMed, Cochrane Library, CHINAL, and PEDro databases were searched for relevant randomized controlled trials (RCTs).
Repeated transcranial magnetic stimulation on the bilateral cerebellum to improve symptoms of ataxia with multiple system atrophy: a prospective, randomized, sham-controlled pilot study.
Neurol Sci
January 2025
Department of Neurology, Baotou Central Hospital, Baotou, Inner Mongolia, China.
Objectives: Ataxia is a common symptom in patients with Cerebellar subtype of Multiple system atrophy (MSA-C), but effective treatments remain elusive. The present study aims to investigate whether repetitive transcranial magnetic stimulation (rTMS) over the bilateral cerebellum could relieve ataxia in patients with MSA-C.
Patients And Methods: This is a single-center, randomized and double-blind trial.
Associations between CAG repeat size, brain and spinal cord volume loss, and motor symptoms in spinocerebellar ataxia type 3: a cohort study.
Orphanet J Rare Dis
January 2025
Department of Neurology of First Affiliated Hospital, Fujian Medical University, Fuzhou, 350005, China.
Background: Spinocerebellar ataxia type 3 (SCA3) is a hereditary disease caused by abnormally expanded CAG repeats in the ATXN3 gene. The study aimed to identify potential biomarkers for assessing therapeutic efficacy by investigating the associations between expanded CAG repeat size, brain and spinal cord volume loss, and motor functions in patients with SCA3.
Methods: In this prospective, cross-observational study, we analyzed 3D T1-weighted MRIs from 92 patients with SCA3 and 42 healthy controls using voxel-based morphometry and region of interest approaches.
