Noninvasive measurement of the human brain's angioarchitecture is essential for understanding functional neuroimaging signals, diagnosing cerebrovascular diseases, and tracking neurodegeneration. Ultrahigh-field MRI now enables mesoscopic (<0.5 millimeters) imaging, revealing vascular details previously inaccessible in vivo. [...]

Socio-cognitive assessment in neurocognitive disorders (NCDs) is rare in clinical practice and no consensus exists as to a uniform operationalization of socio-cognitive measures for NCDs in memory clinics. The SIGNATURE initiative aims to optimize the use of socio-cognitive measures in memory clinics, defining expert recommendations. [...]

Hunger and satiety are influenced by both the amount and composition of dietary fat.This exploratory analysis examined the effects of meals enriched with different amounts of either canola oil (rich in unsaturated fatty acids) or coconut oil (rich in saturated fatty acids) on postprandial changes in subjective hunger and satiety ratings, related hormones, attention, and memory.Twenty-nine participants with an increased cardiometabolic disease risk (e.g., body mass index, 30.2 ± 2.6 kg/m2) received 4 isoenergetic (∼4200 kJ) test meals in a randomized order: high-fat meals (HFMs) (50 g) or low-fat meals (LFMs) (25 g) containing either canola or coconut oil. Hunger and satiety ratings, blood samples for ghrelin and peptide YY (PYY), and cognitive tests were conducted at fasting and over a 6-h postprandial period. [...]

VPS13A disease (chorea-acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease.We systematically assessed the neuromuscular involvement in six patients with VPS13A disease. [...]

Alzheimer's disease (AD) is one of the most prevalent causes of dementia, while concomitant diseases such as cerebral amyloid angiopathy (CAA) has a substantial impact on clinical trajectories and therapy, i.e. risk factor for imaging abnormalities under anti-amyloid antibodies. [...]

Mitochondria and the endoplasmic reticulum (ER) contain large areas that are in close proximity. Yet the mechanism of how these inter-organellar adhesions are formed remains elusive. [...]

Heterozygous missense mutations in MORC2 have been implicated in various clinical entities, ranging from early-onset neurodevelopmental disorders to late-onset neuropathies. The mechanism underlying the phenotypic heterogeneity and pleiotropic effects of MORC2 has remained elusive. [...]

Tau species lacking truncation of the N-terminal region, including plasma N-terminal tau fragment 1 (NT1), have been previously associated with cognitive decline, neurodegeneration, and tau pathology in late-onset sporadic Alzheimer's disease (AD).Here, we examined cross-sectional and longitudinal plasma NT1 as a possible predictor of cognitive, clinical, and core AD biomarker trajectories in autosomal dominant AD (ADAD).NT1 levels in ADAD mutation carriers (MC; n = 132) increased across the disease continuum, compared to non-carriers (NC; n = 75), becoming elevated about a decade prior to estimated symptom onset. Cross-sectional and longitudinal NT1 levels in MC were associated with clinical, cognitive, and biomarker changes. [...]

There is substantial heterogeneity in clinical presentation of genetic Frontotemporal Dementia (FTD), even within the same family. This suggests that additional heritability may exist and contribute to this variable presentation. [...]

Aggregation of amyloid beta (Aβ) and tau proteins is a hallmark of Alzheimer's disease (AD) and tauopathies. In AD, extracellular deposition of Aβ peptide precedes tau aggregation and the onset of neuroinflammatory processes. [...]
