Synapsins are the proteins responsible for recruiting synaptic vesicles into the synaptic vesicle cluster. As one of the most abundant synaptic proteins, synapsins are well known to directly interact with the synaptic vesicles, but they can also interact with planar membranes, notably the synaptic membrane, at least indirectly by tethering vesicles to the active zone. [...]

We present an open, vendor-neutral BOLD SMS-EPI protocol tailored for multi-site fMRI studies, intended as a drop-in replacement for conventional vendor-specific acquisition and reconstruction pipelines. Built on Pulseq-an emerging standard for cross-platform MRI pulse sequence development-our protocol ensures identical SMS-EPI pulse sequences and image reconstruction across scanner vendors. [...]

Chronic traumatic encephalopathy (CTE) is a tauopathy linked to repetitive head impacts. Factors influencing brain regional susceptibility to tau deposition and spreading remain unclear.We used three datasets: [18F]flortaucipir positron emission tomography (PET) in 157 former professional American football players and 53 controls (DIAGNOSE CTE); cortical myelin water fractions (MWF) in 50 healthy individuals (Myelin Water Atlas); and white matter (WM) tract MWF and functional connectivity (FC) in 100 healthy individuals (Human Connectome Project). [...]

Dementia affects over 50 million individuals globally, predominantly due to Alzheimer's disease (AD). Effective early detection and intervention remain clinical challenges, as there is a lack of unified, portable solutions to assess multiple biomarkers.We evaluated Evoked Potential Tomography (EPT), an EEG-based method using a novel visual evoked potential protocol. [...]

The relevance of prior antithrombotic and thrombolytic treatment for decision-making regarding endovascular thrombectomy (EVT) for acute ischemic stroke due to large vessel occlusion with established large infarcts is uncertain. This study investigates associations of prior antithrombotic medication and thrombolysis with the efficacy and safety of EVT for acute ischemic stroke due to large vessel occlusion with established large infarct.TENSION (Efficacy and Safety of Thrombectomy in Stroke With Extended Lesion and Extended Time Window) was a prospective randomized open-label blinded-end point clinical trial. [...]

Cerebellar ataxias (CAs) encompass a wide spectrum of genetic and sporadic origins, of which a portion is driven by immune-mediated pathomechanisms. While some patients harbor known autoantibodies, assisting diagnosis and treatment, many remain seronegative. [...]

Microglia are the brain's resident immune cells, essential for homeostasis and implicated in common neurodegenerative diseases like Alzheimer's and Parkinson's disease (PD), where their early activation and sustained inflammatory mediator release contribute to neuronal loss. However, their role in rare disorders is unclear. [...]

Serum glial fibrillary acidic protein (sGFAP) is an astroglial biomarker preliminarily investigated in acute ischemic stroke (AIS). We aimed to investigate its temporal pattern and clinical value in two German AIS cohorts. [...]

Weight loss, partially caused by hypermetabolism, represents a well-documented and therapeutically relevant feature of the amyotrophic lateral sclerosis phenotype worldwide. In this study, we retrospectively analysed the association between thyroid function and clinical, prognostic and metabolic parameters in a cohort of patients with amyotrophic lateral sclerosis in an experienced centre in Germany (n = 1754). [...]

BACKGROUND: Life expectancy for individuals with Down syndrome (DS) has significantly increased, primarily due to medical advances. While DS is considered a genetically determined form of Alzheimer’s disease (DS-AD), with neuropathological markers evident by age 40, the onset of clinical dementia varies. [...]
