Article Synopsis
  • The study explored the link between neuropsychiatric symptoms (NPS) and frontotemporal atrophy (FTA) in older adults without dementia, specifically looking at those with mild cognitive impairment (MCI) and cognitively unimpaired (CU) individuals.
  • It was found that older adults with MCI and FTA had significantly higher odds of experiencing certain NPS such as elation, aberrant motor behavior, and apathy compared to those without FTA.
  • Conversely, the analysis indicated that CU individuals did not show significantly elevated odds of NPS with FTA, suggesting that the relationship between FTA and NPS may primarily affect those with cognitive impairments.

This narrative review explores the current landscape of blood biomarkers in Frontotemporal dementia (FTD). Neurofilament light chain (NfL) may be useful in the differentiation of behavioral variant FTD from primary psychiatric disorders (PPDs) or dementia with Lewy bodies (DLB). In prodromal FTD and presymptomatic mutation carriers (, , ), elevated NfL may herald pheno-conversion to full-blown dementia.

Article Synopsis
  • The study aimed to determine how motor signs in older adults with mild cognitive impairment (MCI) can predict the onset of dementia with Lewy bodies (DLB), especially focusing on differences between sexes.
  • Researchers analyzed data from individuals over 55 years old, assessing various motor signs like resting tremor and bradykinesia, and found that certain signs significantly increased the risk of developing DLB, particularly in women.
  • Results indicated that masked facies and resting tremor raised the risk of DLB considerably in women compared to men, while other motor signs like rigidity and hypophonia impacted the risk of different types of dementia, but not all motor features correlated with dementia risk.

While there is a link between homocysteine (Hcy), B12 and folic acid and neurodegeneration, especially in disorders like Parkinson's and Alzheimer's diseases, its role in Parkinson plus syndromes (PPS) has only been partially investigated. It appears that elevated Hcy, along with an imbalance of its essential vitamin cofactors, are both implicated in the development and progression of parkinsonian syndromes, which represent different disease pathologies, namely alpha-synucleinopathies and tauopathies. Attributing a potential pathogenetic role in hyperhomocysteinemia would be crucial in terms of improving the diagnostic and prognostic accuracy of these syndromes and also for providing a new target for possible therapeutic intervention.

Background: Management of intracerebral hemorrhage (ICH) is challenged by limited therapeutic options and a complex relationship between blood pressure (BP) dynamics, especially BP variability (BPV) and ICH outcome.

Methods: In an exploratory analysis of prospectively collected data on consecutive patients with nontraumatic ICH between 2015 and 2020, continuous BP accessed via an arterial line extracted from the Intellispace Critical Care and Anesthesia information system (Philips Healthcare) was analyzed over the first 72 h post admission. Arterial lines were used as part of standard clinical practice in the intensive care, ensuring high fidelity and real-time data essential for acute care settings.

Article Synopsis
  • - The study aimed to explore cognitive deficits during transient global amnesia (TGA) episodes, discovering that impairments extend beyond just episodic memory.
  • - Researchers reviewed 1302 articles, ultimately including 17 in their analysis, and found that TGA patients experience significant issues with spatiotemporal awareness, anterograde amnesia, and working memory during acute episodes.
  • - Although many cognitive functions remain normal, recovery typically starts with spatiotemporal orientation, followed by working and semantic memory retrieval, while episodic memory issues may last longer, with subtle memory deficits possible even after 24 hours.

Chronic migraine (CM) imposes significant personal, societal, and financial burdens, historically lacking specific prophylactic treatments. Monoclonal antibodies (mAbs) targeting calcitonin gene-related peptide (CGRP) represent a novel, mechanism-based, and migraine-specific prophylactic approach. Four mAbs, namely, erenumab, fremanezumab, galcanezumab, and eptinezumab, have been marketed, although head-to-head trials with standard anti-migraine treatments are absent.

Article Synopsis
  • The study investigates the relationship between body mass index (BMI) and Parkinson's disease (PD) using a method called Mendelian randomization to determine if higher genetically predicted BMI is linked to a lower incidence of PD.
  • Researchers analyzed genetic data from large groups of individuals, including over 800,000 for BMI and nearly 29,000 for PD, focusing on factors like age, disease duration, and gender to examine the associations.
  • Results indicated an inverse relationship between genetically predicted BMI and PD, particularly among younger participants and women, suggesting that lower BMI may be associated with a higher risk of developing Parkinson's disease.

Introduction: Circulating T follicular helper (cTfh) cells and circulating T peripheral helper (cTph) cells (which share common characteristics with the cTfh population) are implicated in the pathogenesis of immune-mediated and autoimmune diseases such as psoriasis (Ps). Their close interplay with the interleukin 17 (IL-17) axis and the ex vivo effect of IL-17-targeting biologic agents used to treat Ps on them are elusive. This study aimed to investigate the effect of biologics targeting IL-17 on cTfh and cTph cell subpopulations isolated from the blood of patients with Ps.
