Magnetic resonance imaging (MRI) is the gold standard imaging technique for diagnosis and monitoring of many neurological diseases. However, the application of conventional MRI in clinical routine is mainly limited to the visual detection of macroscopic tissue pathology since mixed tissue contrasts depending on hardware and protocol parameters hamper its application for the assessment of subtle or diffuse impairment of the structural tissue integrity. Multiparametric quantitative (q)MRI determines tissue parameters quantitatively, enabling the detection of microstructural processes related to tissue remodeling in aging and neurological diseases. In contrast to measuring tissue atrophy via structural imaging, multiparametric qMRI allows for investigating biologically distinct microstructural processes, which precede changes of the tissue volume. This facilitates a more comprehensive characterization of tissue alterations by revealing early impairment of the microstructural integrity and specific disease-related patterns. So far, qMRI techniques have been employed in a wide range of neurological diseases, including in particular conditions with inflammatory, cerebrovascular and neurodegenerative pathology. Numerous studies suggest that qMRI might add valuable information, including the detection of microstructural tissue damage in areas appearing normal on conventional MRI and unveiling the microstructural correlates of clinical manifestations. This review will give an overview of current qMRI techniques, the most relevant tissue parameters and potential applications in neurological diseases, such as early (differential) diagnosis, monitoring of disease progression, and evaluating effects of therapeutic interventions.

Intracranial calcifications (ICCs) are a characteristic neuropathological feature of several congenital viral infections, including Zika virus (ZIKV), cytomegalovirus (CMV), and lymphocytic choriomeningitis virus (LCMV). These lesions are linked to severe neurodevelopmental outcomes, such as microcephaly, epilepsy, and cognitive deficits, yet the mechanisms underlying their formation and resolution remain unclear. ICCs are thought to arise from an imbalance in osteogenic and osteolytic signaling in the developing brain.

Adenylosuccinate lyase deficiency (ADSLd) is a rare autosomal recessive purine metabolism disorder with several clinical manifestations. While toxic substrate accumulation is a known hallmark, no additional molecular mechanisms have been established. Here, we show that ADSLd is associated with mitochondrial dysfunction, including increased fragmentation, impaired respiration, and reduced ATP production.

It has become evident from decades of clinical trials that multimodal therapeutic approaches with focus on cell intrinsic and microenvironmental cues are needed to improve understanding and treat the rare, inoperable, and ultimately fatal diffuse intrinsic pontine glioma (DIPG), now categorized as a diffuse midline glioma. In this study we report the development and characterization of an in vitro system utilizing 3D Tumor Tissue Analogs (TTA), designed to replicate the intricate DIPG microenvironment. The innate ability of fluorescently labeled human brain endothelial cells, microglia, and patient-derived DIPG cell lines to self-assemble has been exploited to generate multicellular 3D TTAs that mimic tissue-like microstructures, enabling an in- depth exploration of the spatio-temporal dynamics between neoplastic and stromal cells.

Purpose: The purpose was to identify how the ICECAP-A and ICECAP-O have been used with adults who have neurological health conditions.
Methods: Following the Joanna Briggs Institute framework, a scoping review was conducted, searching five databases (Scopus, CINAHL, MEDLINE, Embase, and PsycINFO). Studies were included if participants were adults (age 18+ years) with neurological health conditions, and ICECAP-A or ICECAP-O were used in the study.

Background And Aims: Dynapenic abdominal obesity has been shown as a risk factor for adverse outcomes. There is no evidence on the longitudinal association of this condition with different courses of depressive symptoms. This study aimed to investigate the association of dynapenic abdominal obesity status with the risk of distinct trajectories of depressive symptoms.
