Pathogenic mechanisms of autoantibodies in neurological autoimmune diseases.
Over recent decades, the significance of autoantibodies has been increasingly recognized in neurological diseases. Breakthroughs, such as the identification of pathogenic autoantibodies targeting aquaporin-4 in central nervous system demyelinating disorders and N-methyl-D-aspartate receptors in autoimmune encephalitis, have revolutionized both the discovery and mechanistic investigation of autoantibodies in neurological diseases.

Extracorporeal therapy procedures (plasma exchange and immunoadsorption) in chronic inflammatory demyelinating polyneuropathies (CIDP)- a database analysis.
Background and objectivesThere is limited study data on both therapeutic plasma exchange (PE) and immunoadsorption (IA) in chronic inflammatory demyelinating polyneuropathy (CIDP), mostly based on case series in patients in the early stages of the disease.The aim of this retrospective study was to compare the efficacy and tolerability of the two therapy procedures in a larger sample with a longer duration of disease and immunomodulatory pre-treatment.MethodsIn this retrospective study from 5 centers in Germany, register data on the efficacy, safety and tolerability of therapy with IA or PE in patients with CIDP were examined. Treatment response was assessed using neurological scores (INCAT and Hughes Score), duration of hospital stay, and subjective assessment by examiners and patients. [...]

Cognitive and mental health outcomes in long covid.
Roughly one in five adults who meet criteria for long covid present with objective or subjective cognitive dysfunction or elevated symptoms of depression or anxiety lasting ≥12 weeks from an acute covid illness. These neuropsychiatric sequelae have considerable functional consequences at the level of the individual, society, and the broader economy. [...]

Dementia risk estimation in persons at risk and the predictive turn in Alzheimer's disease-The PreTAD project: Study protocol with an ethical, clinical, linguistic, and legal approach.
Despite progress in the field of Alzheimer's disease (AD) dementia risk estimation, little is known about its impact at the individual and societal levels.Introducing the explorative tri-national PreTAD project (The Predictive Turn in Alzheimer's Disease: Ethical, Clinical, Linguistic and Legal Aspects), which aims to (1) learn about attitudes, needs, and perspectives on AD dementia risk estimation of the general population and cognitively unimpaired individuals with and without contact to memory clinics, (2) identify anticipated impacts of AD dementia risk estimation and (3) discuss the implications of the paradigm shift in medicine at individual and societal levels from an ethical, linguistic and legal perspective.Different approaches are used: (1) an assessment of a population without experience with dementia, (2) an assessment in memory clinics, and (3) an online survey of the general population. Participants include cognitively healthy adults (n=2760), first-degree relatives of dementia patients (n=150), and participants with existing (n=150) and newly diagnosed (n=90) subjective cognitive decline (SCD) from Germany, Switzerland, and Spain.As part of the PreTAD project, new questionnaires are developed that (1) collect attitudes, needs, and perspectives on AD dementia risk estimation and (2) assess anticipated impacts of dementia risk estimation using hypothetical blood-based biomarker dementia risk scenarios.The PreTAD study combines an interdisciplinary approach to develop a framework for predictive medicine in the preclinical stages of AD and supports improving communication of biomarker-based dementia risk estimation in clinical practice.

Regional effects of gantenerumab on neuroimaging biomarkers in the DIAN-TU-001 trial.
Monoclonal anti-amyloid therapies are now accessible, but how these treatments influence changes within the brain is still not clear. We investigated overall and regional change in amyloid removal, glucose metabolism, and atrophy in trial participants with dominantly inherited Alzheimer's disease (DIAD).In the DIAN-TU-001 trial, 92 carriers received gantenerumab or placebo and underwent serial neuroimaging assessments including [11C]-Pittsburgh compound-B (PiB) positron emission tomography (PET), [18F]-fluoro-2-deoxyglucose (FDG) PET, and magnetic resonance imaging (MRI).Gantenerumab significantly reduced PiB-PET uptake overall and in most regions and showed no changes in FDG-PET or MRI measures.

Educational attainment, electroencephalographic rhythms, cortical structure, and cognitive performance over 2 years in older adults with subjective memory complaints and brain amyloidosis.
We investigated whether older adults with subjective memory complaints (SMC) and amyloid-β accumulation may show clinical progression over 2 years, as measured by resting-state electroencephalographic (rsEEG), structural magnetic resonance imaging (sMRI), and cognitive variables, depending on educational attainment.We analyzed these markers in 84 SMC participants from INSIGHT-Pre-AD study, grouped by amyloid-β deposition (18F-florbetapir positron emission tomography) and educational attainment.In amyloid-negative individuals, higher educational attainment was linked to greater posterior rsEEG alpha activity, possibly reflecting neuroprotective effects. Conversely, amyloid-positive individuals with higher educational attainment showed reduced posterior rsEEG alpha rhythms and lower parietal cortical thickness, potentially indicating compensatory mechanisms counteracting early amyloidosis and neurodegeneration.

Circadian clock dysfunction in Parkinson's disease: mechanisms, consequences, and therapeutic strategy.
Parkinson's Disease (PD) is a prevalent neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the substantia nigra. This leads to hallmark motor features that include bradykinesia, resting tremor, rigidity, and postural instability, alongside with a range of non-motor symptoms including sleep disturbances, mood disorders, and cognitive decline.
