The study design of PIMIDES, a trial based on patient-individualized transcranial electric neurostimulation of epileptic foci, is reported. Inclusion criteria include a predominant epileptic focus and pharmacoresistance to two antiepileptic drug treatments. The study is prospective, unblinded, and serves to assess the safety of subgaleal implantation and transcranial stimulation.This paper aims to provide an overview of the use and assessment of qualitative research methods in the health sciences. Qualitative research can be defined as the study of the nature of phenomena and is especially appropriate for answering questions of why something is (not) observed, assessing complex multi-component interventions, and focussing on intervention improvement. The most common methods of data collection are document study, (non-) participant observations, semi-structured interviews and focus groups. For data analysis, field-notes and audio-recordings are transcribed into protocols and transcripts, and coded using qualitative data management software. Criteria such as checklists, reflexivity, sampling strategies, piloting, co-coding, member-checking and stakeholder involvement can be used to enhance and assess the quality of the research conducted. Using qualitative in addition to quantitative designs will equip us with better tools to address a greater range of research problems, and to fill in blind spots in current neurological research and practice.
Cerebral small vessel disease (CSVD) is a disorder of brain vasculature that causes various structural changes in the brain parenchyma, and is associated with various clinical symptoms such as cognitive impairment and gait disorders. Structural changes of brain arterioles cannot be visualized with routine imaging techniques in vivo. However, optical coherence tomography (OCT) is thought to be a "window to the brain". Thus, retinal vessel parameters may correlate with CSVD characteristic brain lesions and cerebrospinal fluid biomarkers (CSF) of the neuropathological processes in CSVD like endothelial damage, microglial activation and neuroaxonal damage.

We applied OCT-based assessment of retinal vessels, magnetic resonance imaging (MRI), and CSF biomarker analysis in a monocentric prospective cohort of 24 patients with sporadic CSVD related stroke and cognitive impairment. MRI lesions were defined according to the STandards for ReportIng Vascular changes on nEuroimaging (STRIVE). Biomarkers were assessed uFurther prospective studies should clarify whether retinal vessel parameters and CSF biomarkers may serve to monitor the natural course and treatment effects in clinical studies on CSVD.
In this exploratory study, WLR correlated with the volume of white matter hyperintensities, and markers of vascular integrity, microglial activation, and neuroaxonal damage in CSVD. Further prospective studies should clarify whether retinal vessel parameters and CSF biomarkers may serve to monitor the natural course and treatment effects in clinical studies on CSVD.
About 6.2 million adults in Germany cannot read and write properly despite attending school for several years. They are considered to be functional illiterates (FI). Since the ability to read and write is crucial for being employed and socially accepted, we developed a special literacy training to overcome these deficits.

In this study, we investigate training-related changes in intrinsic functional connectivity (iFC) at rest in a group of 20 FI and 20 adult normal readers using resting state functional magnetic resonance imaging (rsfMRI). click here We used independent component analysis (ICA) to define different networks.

Before training, the between group analysis showed increased iFC in FI in a left-fronto-parietal network (LFPN; anterior insula, medial frontal cortex, lateral and frontal parietal regions) and in the Basal Ganglia network (BGN thalamus, caudate, putamen, pallidum, amygdala, supplementary motor cortex and cingulate gyrus). link2 Furthermore, the Visual Network-1 (VN1; temporal occipital fusiform gyrul connectivity between and within neural networks important for literacy skills.Monoclonal antibodies against the calcitonin gene-related peptide (CGRP) receptor (Erenumab) or against CGRP (Eptinezumab, Fremanezumab, Galcanezumab) are new substances for the preventive treatment of migraine. They represent an extension of the therapeutic options, which already exist in migraine prevention. In randomized, placebo-controlled studies, the efficacy and good tolerability of these specific substances have been demonstrated in patients with episodic and chronic migraine. The following treatment recommendation presents a summary of the pivotal studies. Recommendations are provided for the targeted selection of patients as well as for the evaluation of therapeutic success and the duration of treatment. Finally, possible restrictions on the use of this new substance group are discussed. This guideline is an abridged and translated version of the guideline published by Diener H-C, May A et al., Prevention of migraine with monoclonal antibodies against CGRP or the CGRP receptor, Supplement to S1 Guideline Therapy of Migraine Attack and Prevention of Migraine, 2019, Deutsche Gesellschaft für Neurologie (eds.), Guidelines for Diagnostics and Therapy in Neurology. A complete version of this guideline can be found on the website of the Deutsche Gesellschaft für Neurologie (www.dgn.org/leitlinien) and the AWMF (Arbeitsgemeinschaft wissenschaftlicher Medizinischer Gesellschaften). This guideline has been approved by the German Neurological Society (DGN) and the German Migraine and Headache Society (GMHS) and was reviewed by the two societies.
Stroke and its long-term consequences pose major challenges for the lives of those affected and healthcare systems. Neurological rehabilitation therefore primarily attempts to improve function in order to increase independence in activities of daily living, and to enable social participation. There is only scarce data on dynamics of functional recovery after patients discharge from inpatient neurological rehabilitation. Even less is known about the patient's perspective on long-term recovery from stroke. The Interdisciplinary Platform for Rehabilitation Research and Innovative Care of Stroke Patients (IMPROVE) aims to address this knowledge gap by providing new insights into the dynamics and extent of functional recovery from stroke beyond inpatient rehabilitation treatment.

We provide the protocol for an observational, longitudinal, multicenter study conducted in an Universitary Stroke Center in cooperation with five Neurological Rehabilitation Centers in Northern Germany. Patients who suffered from ischcome will be analyzed using linear regression analysis.

The results of IMPROVE will inform about the long-term dynamics of functional stroke recovery after patients' discharge from inpatient rehabilitation and will provide insights into the association of clinical and demographic factors with recovery of function.

The protocol is registered at ClinicalTrials.gov (NCT04119479).

Removal of a tracheostomy tube in critically ill neurologic patients is a difficult issue, particularly due to the high incidence of oropharyngeal dysphagia. For an objective evaluation of decannulation readiness the "Standardized Endoscopic Swallowing Evaluation for Tracheostomy Decannulation in Critically Ill Neurologic Patients" (SESETD) - a stepwise evaluation of 'secretion management', 'spontaneous swallows' and 'laryngeal sensibility/cough' - has been introduced. With the recent study detailed data on inter-rater and test-retest reliability are presented.

To obtain inter-rater reliability levels both in a group of raters with at least 5 years of experience ('experts') and in a group of raters with no or only minor experience using the SESETD ('non-experts'), for each single item of the protocol and the sum score α-, respectively κ-levels were determined. The 'experts' assessed the same videos after a four-week interval to determine test-retest reliability. Ten videos from tracheostomized neurologica measure for clinical trials.
The SESETD demonstrates good to excellent agreement for each single item included as well as the sum score in experienced and unexperienced raters supporting its usefulness for implementation in daily clinical routine and as an outcome measure for clinical trials.
Cerebrospinal fluid (CSF) analysis is important for detecting inflammation of the nervous system and the meninges, bleeding in the area of the subarachnoid space that may not be visualized by imaging, and the spread of malignant diseases to the CSF space. In the diagnosis and differential diagnosis of neurodegenerative diseases, the importance of CSF analysis is increasing. Measuring the opening pressure of CSF in idiopathic intracranial hypertension and at spinal tap in normal pressure hydrocephalus constitute diagnostic examination procedures with therapeutic benefits.Recommendations (most important 3-5 recommendations on a glimpse) The indications and contraindications must be checked before lumbar puncture (LP) is performed, and sampling CSF requires the consent of the patient.Puncture with an atraumatic needle is associated with a lower incidence of postpuncture discomfort. The frequency of postpuncture syndrome correlates inversely with age and body mass index, and it is more common in women and patiecently prepared by the German Society for CSF analysis and clinical neurochemistry (DGLN) and published in German in accordance with the guidelines of the AWMF (https//www.awmf.org). link3 /uploads/tx_szleitlinien/030-141l_S1_Lumbalpunktion_und_Liquordiagnostik_2019-08.pdf).

Stroke is the leading cause of acquired disability in western societies. (Motor) cognitive deficits like apraxia significantly contribute to disability after stroke, harming activities of daily living and rehabilitation outcome. To date, efficient therapeutic options for apraxia remain sparse. Thus, randomized controlled trials (RCTs) are warranted.

Based on promising results of a pilot study, the on-going RAdiCS (
ehabilitating stroke-induced
praxia with
rect
urrent
timulation) study is a randomized controlled trial, which follows a double-blinded (investigator and patient), two-arm parallel interventional model. It is designed to include 110 apraxic patients (as diagnosed by the Cologne Apraxia Screening, KAS) in the subacute phase after a left hemisphere (LH) stroke. The University of Cologne initiated the trial, which is conducted in two German Neurorehabilitation Centers.The study aims to evaluate the effect of anodal (versus sham) transcranial direct current stimulation (tDCS) applied over the left posterior parietal cortex (PPC) with an intensity of 2 mA for 10 min on five consecutive days on apraxic deficits.
