Fifteen healthy participants received anodal, cathodal, and sham tDCS (15 min × 2 mA intensity) over the right cerebellar hemisphere during a TP task. We recorded reaction times (RTs) to a target during the task in two contextual conditions of temporal anticipation: rhythmic (i.e., interstimulus intervals (ISIs) were constant) and single-interval condition (i.e., the estimation of the timing of the target was based on the prior exposure of the train of stimuli). Two ISIs durations were explored: 600 ms (short trials) and 900 ms (long trials). Cathodal tDCS improved the performance during the TP task (shorter RTs) specifically in the rhythmic condition only for the short trials and in the single-interval condition only for the long trials. Our results suggest that the inhibition of cerebellar activity induced a different improvement in the TP ability according to the temporal features of the context. In the rhythmic context, the cerebellum could integrate the temporal estimation with the anticipatory motor responses critically for the short target interval.

Serum concentrations of S100β were measured by enzyme-linked immunosorbent assay in 39 SCA2 subjects and 36 age- and gender-matched controls. Clinical scores of ataxia, non-ataxia symptoms, cognitive dysfunction, and some blood cell count-derived inflammatory indices were assessed. The SCA2 individuals manifested S100β levels similar to the control group, at low nanomolar concentrations. However, the S100β levels were directly associated with a better performance of cognitive evaluation within the SCA2 cohort. Moreover, the S100β levels were inversely correlated with most peripheral inflammatory indices. Indeed, the neutrophil-to-lymphocyte ratio significantly mediated the effect of serum S100β on cognitive performance, even after controlling for the ataxia severity in the causal mediation analysis.

The retrospective study included the patients with AA treated in the institute from 2015 to 2021. The inclusion criteria were children aged 1-18 years, evolution time of ataxia within 72 h, and diagnosis made by a physician. The exclusion criteria were anamnestic data about ataxia without confirmation by any physician, chronic/persistent ataxia, and psychogenic or postictal ataxia. Clinical presentation was divided into two categories: (1) isolated cerebellar signs (CS): ataxic gait, dysmetria, dysdiadochokinesia, intention tremor, dysarthria, and nystagmus; (2) CS-plus symptoms which included CS associated with any of other symptoms such as encephalopathy (GCS < 15), awareness disturbances, vomiting, headache, a new onset limb or facial paresis, torticollis, hypotonia, and opsoclonus. The outcome was assessed at the end of hospitalization and was defined as complete or incomplete recovery. The study included 76 children, with a mean age of 5.7 years (IQR 2.1-8.3). The most frequent causes of AA were immune-mediated/infective cerebellar ataxia in 27 (35.5%), and intoxication in 24 (31.6%) cases, followed by vestibular ataxia, opsoclonus-myoclonus-ataxia syndrome, and intracranial expansive process. Forty-two (56%) cases experienced isolated CS, and 35 (46%) cases had CS-plus. Complete recovery was experienced by 62 (81.6%) patients. Analysis of some risk factors (sex, age, presence of previous infection, \"cerebellar plus symptoms,\" and structural abnormalities/neuroimaging abnormalities) and their relation to outcome was performed. Analysis showed that presence of additional symptoms to ataxia, so called \"cerebellar plus symptoms\" (p = 0.002) and structural abnormalities (p < 0.001), had statistically higher frequency of poor outcome. Statistical significance remained in the univariate analysis. Significant data was included in multivariate logistic regression analysis which also showed that presence of \"cerebellar plus symptoms\" (p = 0.021) and structural abnormalities (p = 0.002) is related to a poor outcome.

This study aims to conduct a comprehensive systematic review and meta-analysis in order to assess the efficacy of various NIBS methods for the treatment of HA. A thorough review of the literature was conducted, encompassing both English and Chinese articles, across eight electrical databases. The focus was on original articles investigating the therapeutic effectiveness of non-invasive brain stimulation for hereditary ataxia, with a publication date prior to March 2023. Subsequently, a meta-analysis was performed specifically on randomized controlled trials (RCTs) that fulfilled the eligibility criteria, taking into account the various modalities of non-invasive brain stimulation. A meta-analysis was conducted, comprising five RCTs, which utilized the Scale for the Assessment and Rating of Ataxia (SARA) as the outcome measure to evaluate the effects of transcranial magnetic stimulation (TMS). The findings revealed a statistically significant mean decrease of 1.77 in the total SARA score following repetitive TMS (rTMS) (p=0.006). Subgroup analysis based on frequency demonstrated a mean decrease of 1.61 in the total SARA score after high-frequency rTMS (p=0.05), while no improvement effects were observed after low-frequency rTMS (p=0.48). Another meta-analysis was performed on three studies, utilizing ICARS scores, to assess the impact of rTMS. The results indicated that there were no statistically significant differences in pooled ICARS scores between the rTMS group and the sham group (MD=0.51, 95%CI: -5.38 to 6.39; p=0.87).

The dependent variable of this cross-sectional study was the self-selected speed and the factors (independent variables) were age, sex, balance, balance confidence, knee flexion and extension cocontraction indexes, lower limb coordination, passive range of motion of ankle dorsiflexion, knee and hip extension, and global spasticity. Multiple regression models were used to assess the relationships between walking speed and each factor individually. Six factors were significantly associated with walking speed and thus included in regression models.

The factors that most influence self-selected walking speed are balance and lower limb coordination. In order of importance, the other factors that also significantly influence self-selected walking speed are ankle dorsiflexion range of motion, lower limb spasticity, knee extension range of motion, and confidence in balance.
