Introduction: Intraventricular hemorrhage (IVH) in the neonatal period has been associated to developmental impairment or delay in preterm born children and adolescents. To our knowledge there is no study in literature which describes the effects of neonatal IVH in preterm subjects on different specific cognitive functions in adolescent samples. AIM. To explore general as well as specific cognitive performance in preterm adolescents with neonatal IVH, through a comprehensive neuropsychological assessment.
Subjects And Methods: Sixteen preterm born adolescents with IVH in the newborn period and thirty matched controls were recruited for neuropsychological testing. The intelligence quotient, learning, memory, visuospatial and visuoperceptive abilities, and frontal functions were evaluated.
Results: Significant differences were observed for full and performance intelligence quotient, as well as for several specific cognitive functions. After controlling for full intelligence quotient, and compared with preterm adolescents without IVH, differences remained significant for verbal learning and verbal memory. Subjects with IVH grades III-IV scored significantly lower than those with IVH grades I-II in verbal learning, everyday memory and visuoconstructive and visuospatial abilities.
Conclusions: The present study suggests that long-term difficulties are evident for general cognitive performance as well as for specific cognitive abilities in preterm subjects with IVH in the newborn period. These data could explain the academic problems shown by these individuals and may suggest concrete intervention programs to minimize the effects of such deficits.

Many diseases and disorders of the nervous system suffer from a lack of adequate therapeutics to halt or slow disease progression, and to this day, no cure exists for any of the fatal neurodegenerative diseases. In part this is due to the incredible diversity of cell types that comprise the brain, knowledge gaps in understanding basic mechanisms of disease, as well as a lack of reliable strategies for delivering new therapeutic modalities to affected areas. With the advent of single cell genomics, it is now possible to interrogate the molecular characteristics of diverse cell populations and their alterations in diseased states.

Background And Objectives: Primary care is often the first point of contact for patients with cognitive complaints, making initial cognitive screening an essential step to avoid delays in diagnosing Alzheimer's disease (AD) at an early stage. We developed MemScreen, a self-administered smartphone application that assesses overall cognition and verbal memory, and evaluated its ability to detect mild cognitive impairment (MCI) in both general and clinical populations.
Methods: We conducted two validation cohort studies: (1) UK-based Whitehall II cohort study (13th wave, 2018-2022) involving a general population (MCI defined by poor performance on a global cognitive score), and (2) five French memory clinics involving patients without dementia (amnestic MCI defined by the Free and Cued Selective Reminding Test).

As an important member of the Siglec family, SIGLEC-15 plays an important role in osteoclast differentiation, bone remodeling, and tumor immune evasion. In the tumor microenvironment, SIGLEC-15 functions independently of the B7-H1/PD-1 pathway. In this study, the SIGLEC-15 fusion protein (SIGLEC-15-Fc) was successfully expressed and purified using a eukaryotic expression system.

To investigate the diagnostic value of the MTA score according to age, cerebral small vessel disease and in times of automated volumetry. Retrospective analysis of patients with subjective cognitive decline (SCD), amnestic mild cognitive impairment (aMCI), Alzheimer's disease (AD) and mixed dementia (MD) who presented to our outpatient dementia clinic between February 2018 and October 2020. Patients underwent cranial magnetic resonance imaging (MRI) including specific MRI sequences needed for automated volumetry.

Background: Cross-sectional studies have reported neurocognitive performance deficits in obsessive-compulsive disorder (OCD), particularly on tasks assessing response inhibition and proactive control over stimulus-driven behaviors (task control). However, it is not clear whether these deficits represent trait-like markers of OCD or are state-dependent.
Methods: This study examined performance on two neurocognitive tasks in OCD patients (N = 26) before and after cognitive behavioral therapy (CBT) and matched healthy controls (HCs, N = 19).
