Research in people with relapsing remitting multiple sclerosis (PwRRMS) is increasingly focusing on non-motor symptoms like cognitive impairment, fatigue and depression. Due to the high negative impact on quality of life and high socioeconomic costs based on these symptoms, more specific research to improve non-motor symptoms is needed. [...]

PV+ FSBCs are critical for modulating hippocampal oscillations, which are essential for memory and behavior. Our research uses biophysical modeling to propose a cellular, dendritic dependent mechanism: these interneurons can dynamically switch their firing patterns by engaging different dendritic integration modes. [...]

Diagnosing Alzheimer's disease (AD) in adults with Down syndrome (DS), a population with a high genetically determined risk of AD, remains challenging. In this large observational study including n = 2329 samples from the Down Alzheimer Barcelona Neuroimaging Initiative (DABNI) and euploid controls from the Sant Pau Initiative on Neurodegeneration (SPIN) with and without symptomatic AD, we investigate if the strong diagnostic performance of plasma p-tau217 observed in sporadic AD extends to the DS population. [...]

Our understanding of the immune response in tuberculosis (TB) remains incomplete. This applies in particular to extrapulmonary TB (EPTB), a highly heterogeneous disease affecting up to 30% of patients in certain regions. [...]

Thalamic afferents form glutamatergic synapses with striatal medium spiny neurons (MSNs). These projections are involved in complex learning processes and have primarily been studied in rostral striatum. [...]

7 Tesla (T) magnetic resonance imaging (MRI) provides more accurate image resolution than 3 T MRI due to its higher field strength. This could lead to a significant improvement in diagnostics, especially in small anatomical regions like the substructures of the hippocampus and amygdala. [...]

Aging is accompanied by immunoscenescence and chronic low-grade inflammation (inflammaging), contributing to age-related diseases. Physical exercise is a potent modulator of immune function and systemic inflammation, yet the effects of acute exercise intensity on immune activation, cytokine dynamics, and extracellular vesicle release in older adults remain incompletely characterized, particularly in a sex-specific context. [...]

INTRODUCTION:This survey investigated perspectives of research and clinical professionals on optimal content and features of measurement of self-perceived cognitive functioning.METHODS:Respondents were professionals working with older adults with self-reported cognitive concerns. The survey addressed views on harmonization and preferences for items, response formatting, practical features, and instrument validation. [...]

The recent development of brain charts for the human lifespan offers an ideal modelling framework for pathologies such as genetic frontotemporal lobar degeneration (FTLD) which likely involve both neurodevelopmental and neurodegenerative processes over a lifetime. We have therefore combined this new methodological approach with MRI data from asymptomatic and symptomatic subjects, carrying C9orf72, MAPT or GRN mutations from the Genetic FTD Initiative (GENFI) and the ARTFL-LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) study.
