Background and aims. The present study aimed to assess the frequency of spasticity in a single-centre cohort of stroke patients in a one-year follow-up, its predictors, and its impact on the activities of daily living (ADL) and health-related quality of life (HRQoL). Material and methods. A group of 121 consecutive patients with hemiparesis (aged 73 ± 11 years) was selected for further observation, out of 381 Stroke Department patients during one year. At three follow-up assessments three, six and 12 months after stroke, muscle tone and muscle weakness were rated using Modified Ashworth Scale (MAS) and Medical Research Council (MRC); Activities of Daily Living (ADL) and Health Related Quality of Life (HRQoL) were evaluated using the Barthel Index (BI), Modified Rankin Scale (mRS) and an SF-36 questionnaire. Results. Fifty five of 121 (45%) patients after three months had developed spasticity (MAS ≥ 1), and in 19 of the 121 (15%) this spasticity was severe. After one year, 33/94 (35%) patients showed spasticity, and in 19/94 (20%) it was severe. Baseline muscle weakness (MRC), stroke severity as measured by the National Institutes of Health Stroke Scale (NIHSS), and greater disability (BI), were the most significant predictors of persistent post-stroke spasticity. Patients with spasticity had worse HRQoL in terms of their physical functioning, role limitations, physical pain, and vitality. Conclusion. Spasticity, which affects a significant proportion of stroke survivors, was present in 35% of our patients at 12 months after stroke. It has a major impact on both ADL and HRQoL. Severe disability and muscle weakness are the most important predictors of persistent post-stroke spasticity. Background and aims.

Mutations in NADH dehydrogenase (ND) subunits of complex I lead to mitochondrial encephalomyopathies associated with various phenotypes. This report aims to present the patient’s clinical symptomatology in the context of a very rare 13042G>A de novo mutation and with an emphasis on changing phenotypic expression and pronounced, long-standing response to levetiracetam.

Our aim was to analyze the phenotypic-genetic correlations in a patient diagnosed with early onset corticobasal syndrome with progressive non-fluent aphasia (CBS-PNFA), characterized by predominant apraxia of speech, accompanied by prominent right-sided upper-limb limb-kinetic apraxia, alien limb phenomenon, synkinesis, myoclonus, mild cortical sensory loss, and right-sided hemispatial neglect. Whole-exome sequencing (WES) identified rare single heterozygous variants in ATP7B (c.3207C>A), SORL1 (c.352G>A), SETX (c.2385_2387delAAA), and FOXP1 (c.1762G>A) genes. The functional analysis revealed that the deletion in the SETX gene changed the splicing pattern, which was accompanied by lower SETX mRNA levels in the patient’s fibroblasts, suggesting loss-of-function as the underlying mechanism. In addition, the patient’s fibroblasts demonstrated altered mitochondrial architecture with decreased connectivity, compared to the control individuals. This is the first association of the CBS-PNFA phenotype with the most common ATP7B pathogenic variant p.H1069Q, previously linked to Wilson’s disease, and early onset Parkinson’s disease. This study expands the complex clinical spectrum related to variants in well-known disease genes, such as ATP7B, SORL1, SETX, and FOXP1, corroborating the hypothesis of oligogenic inheritance. To date, the FOXP1 gene has been linked exclusively to neurodevelopmental speech disorders, while our study highlights its possible relevance for adult-onset progressive apraxia of speech, which guarantees further study.

Background. As deep brain stimulation (DBS) and radiation therapy (RT) have become established treatments for movement disorders and malignancies respectively, patients being treated with both simultaneously are becoming more frequent. Objectives. Literature regarding the safety of RT in patients with implanted DBS is scarce, and there are no clear guidelines on how to manage them. Methods. We present a follow-up of two Parkinson’s Disease (PD) patients with DBS undergoing RT in the context of previous literature. Results. No adverse events nor malfunctioning of the DBS system were observed. This was in line with previous reports.
Conclusions. Since there are no clear safety guidelines for RT in DBS patients, it is important to document experience in this field. A combined approach involving multidisciplinary discussions between neurosurgeons, radiotherapists, clinical oncologists and neurologists is recommended. Background.

Axial truncal dystonia can present as either flexion or extension, often with a tendency toward lateral movement. Flexion dystonia is more common and may represent a clinical spectrum associated with parkinsonism. In contrast, extensor trunk dystonia is less frequent and exhibits a diverse range of causes. In this paper, we reviewed the literature on axial extensor trunk dystonia. We identified 11 studies involving 49 patients, of which only 10 had idiopathic trunk dystonia. Treatment with botulinum neurotoxin A (BoNT/A) emerged as the most effective therapy; however, many studies did not provide detailed descriptions of the treatment (4/11) and follow-up periods were not specified or short term (up to one–two years). We present four new, well-documented patients with the idiopathic form of extensor trunk dystonia who were treated with BoNT/A with moderate to significant effect according to Global Clinical Impression scale (GCI) and Burke-Fahn-Marsden (BFM) dystonia scale. These cases include long-term follow-up for three patients, all without any adverse events. While the diagnostic process and treatment can be challenging, we recommend using BoNT/A with adjusted doses tailored to the appropriate muscle groups as a first-line treatment.
