Engagement in a variety of lifestyle activities, such as intellectual stimulation, social interaction, and physical exercise, is thought to be a key contributor to cognitive reserve, helping the brain compensate for age-related or pathological changes. An open question is whether restrictions on lifestyle activities, even if relatively brief, might have detrimental effects on cognition. [...]

Most patients with a rare movement disorder (MD) do not receive a molecular diagnosis, and the underlying genetic variants and mediating genes remain elusive. Here, we evaluate the diagnostic accuracy of conventional and next-generation sequencing-based genetic testing strategies in a cohort of 2,811 individuals with ataxia, spastic paraplegia and dystonia. [...]

Post-COVID-19 condition (PCC) manifests with prolonged, heterogeneous symptoms challenging both, diagnosis and therapeutic management. This three-year longitudinal study analyzed data from 93 adults (mean age of 48.9 ± 14.0, 60 female) after confirmed SARS-CoV-2 infection. [...]

Facial features hold information about a person's emotions, motor function, or genetic defects. Since most current mobile devices are capable of real-time face detection using cameras and depth sensors, real-time facial analysis can be utilized in several mobile use cases. [...]

Alzheimer's disease (AD) represents the most common cause of dementia and urgently requires sensitive biomarkers and effective therapies. Extracellular vesicles represent membranous nano-sized particles secreted from cells, which serve as intercellular messengers participating in central nervous system (CNS) homeostasis, but also are implicated in AD pathogenesis. [...]

In Alzheimer's disease (AD), a mismatch between neurological damage and cognitive functioning often is attributed to individual differences in cognitive reserve. Understanding the neural mechanisms of cognitive reserve, which may differ across individuals, could help to assess the therapeutic effectiveness of interventions in AD. [...]

DNA-protein coacervate microparticles can be formed via ionic complexation between DNA and a protein, facilitated by the presence of a nonionic polymer. Despite recent advances in understanding membraneless organelles (MLOs) in eukaryotic cells, their formation through liquid-liquid phase separation remains incompletely elucidated. [...]

LRRC8 channels are volume-regulated anion channels (VRACs) activated by cellular swelling, which mediate regulatory volume decrease in many cell types. Recently, it has been shown that these channels contribute to the release of glutamate from astrocytes. [...]

The aim of this study was to analyze changes in hospital incidence cases and disease severity of autoantibody-associated autoimmune encephalitis (AE) during the COVID-19 pandemic compared with the prepandemic period.A retrospective multicenter study analyzed data from 24 centers within the German Network for Research on Autoimmune Encephalitis (GENERATE). Patients with a new diagnosis of definite antibody-positive autoimmune encephalitis from 2017 to 2022 were included and divided into prepandemic (2017-2019) and pandemic (2020-2022) periods.Among 392 patients, 227 were diagnosed before and 165 during the pandemic (mean 9.5 vs 6.9 per site, p = 0.04). [...]

Legal and technical developments drive data sharing via federated infrastructures, especially in the field of human omics. This requires interoperability across technical, syntactic, organizational, and semantic layers. [...]
