Alzheimers Dement

December 2024

Instituto de Investigaciones Científicas y Servicios de Alta Tecnología (INDICASAT AIP), Centro de Neurociencias, Panamá, Panamá, Panama.

Background: By 2025, an estimated three-quarters of the global population aged 60 and older will live in Latin American and Caribbean countries (LAC), leading to a rise in age-related conditions. The main goal of the Panama Aging Research Initiative - Health Disparities (PARI-HD) research program is to create a platform for multidisciplinary clinical studies that focus on mental health and its diseases such as age-related cognitive decline. This platform would generate a large amount of clinical, neuropsychological, lifestyle, genetic and biomarker data following standardized research protocols.

Alzheimers Dement

December 2024

Cognitive Neuroscience Centre, University of San Andres, Victoria, Buenos Aires, Argentina.

Background: Dementia impacts the way individuals perceive and describe everyday events. Alzheimer's disease (AD) notably affects processing of entities manifested by nouns, while behavioral variant frontotemporal dementia (bvFTD) often presents a detached, third-person perspective. Yet, the potential of natural language processing tools (NLP) to detect these variations in spontaneous speech remains explored.

Alzheimers Dement

December 2024

Sorbonne University, GRC n°21, Alzheimer Precision Medicine (APM), AP-HP, Pitié-Salpêtrière Hospital, Boulevard de L'hôpital, F-75013, Paris, France.

Background: Neuropsychiatric symptoms (NPS), including depression and circadian rhythm disruptions, are early non-cognitive markers along the Alzheimer's Disease (AD) continuum. These pathological states are thought to resemble AD pathogenesis, both of which are characterized by a marked decline in adult hippocampal neurogenesis.

Method: 96 elderly participants divided into three groups based on the global depression scale, neuropsychiatric inventory, clinical dementia rating, and mini-mental status examination.

Alzheimers Dement

December 2024

Centro de Investigación Biomédica en Red sobre Enfermedades Neurodegenerativas, Instituto de Salud Carlos III, Madrid, Spain.

Background: Co-morbid Alzheimer's disease (AD) pathology is a major risk factor for cognitive impairment (CI) in PD, but whether and how AD co-pathology affects the clinical phenotype of PD-CI is incompletely understood. Recently validated plasma biomarkers for AD pathology, such as ptau217, hold great promise to revolutionize the diagnosis of neurodegenerative diseases. Here, we used plasma ptau217 to detect AD co-pathology in a well-characterized cohort of PD patients with CI and examine its associations with APOE4 genotype, cognitive profile, and cerebral hypometabolism on FDG-PET.

Patients with dementia with Lewy bodies display a signature alteration of their cognitive connectome.

Sci Rep

January 2025

Division of Clinical Geriatrics, Centre for Alzheimer Research, Department of Neurobiology, Care Sciences, and Society, Karolinska Institutet, Stockholm, Sweden.

Cognition plays a central role in the diagnosis and characterization of dementia with Lewy bodies (DLB). However, the complex associations among cognitive deficits in different domains in DLB are largely unknown. To characterize these associations, we investigated and compared the cognitive connectome of DLB patients, healthy controls (HC), and Alzheimer's disease patients (AD).

Introduction: Since mechanical thrombectomy has allowed ischemic stroke thrombi retrieval, its exhaustive study has involved a better knowledge of physiopathological processes implied in its formation.

Development: Thrombotic pathways involved in the different vascular beds shared common mechanisms conditioning difficulties in the identification of specific patterns associated with stroke etiology. Other factors as clot formation time, associated inflammatory status or activation of additional immune and coagulation pathways [Neutrophil extracellular traps (NETs) delivery, platelet aggregation, endothelial activation and VonWillebrand Factor release] have been described as determinants in thrombus characteristics.

Late Bone Marrow Mononuclear Cell Transplantation in Rats with Sciatic Nerve Crush: Analysis of a Potential Therapeutic Time Window.

Int J Mol Sci

November 2024

Cátedra de Química Biológica Patológica, Departamento de Química Biológica, Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, Buenos Aires C1113AAD, Argentina.

After peripheral nerve injury, axon and myelin regeneration are key events for optimal clinical improvements. We have previously shown that early bone marrow mononuclear cell (BMMC) transplantation exerts beneficial effects on myelin regeneration. In the present study, we analyze whether there is a temporal window in which BMMCs migrate more efficiently to damaged nerves while still retaining their positive effects.

Cortical hypometabolism in Parkinson's disease is linked to cholinergic basal forebrain atrophy.

Mol Psychiatry

December 2024

Unidad de Trastornos del Movimiento, Servicio de Neurología y Neurofisiología Clínica, Instituto de Biomedicina de Sevilla, Hospital Universitario Virgen del Rocío/Universidad de Sevilla/CSIC/CIBERNED, Sevilla, Spain.

Cortical hypometabolism on FDG-PET is a well-established neuroimaging biomarker of cognitive impairment in Parkinson's disease (PD), but its pathophysiologic origins are incompletely understood. Cholinergic basal forebrain (cBF) degeneration is a prominent pathological feature of PD-related cognitive impairment and may contribute to cortical hypometabolism through cholinergic denervation of cortical projection areas. Here, we investigated in-vivo associations between subregional cBF volumes on 3T-MRI, cortical hypometabolism on [F]FDG-PET, and cognitive deficits in a cohort of 95 PD participants with varying degrees of cognitive impairment.

Medicina Familiar y Comunitaria, Centro de Salud Los Comuneros, Burgos, España.

Childhood and adolescent abuse (MTIA) is a serious and complex global public health problem with potentially devastating effects on the physical and mental health and well-being of people throughout their lives. This is a health issue that, although it was not recognized until a few decades ago, has very serious consequences on the lives of these future adult children and their families. By adopting various forms and modalities (violence, abuse, neglect and others), it is highly prevalent and has serious repercussions on personal development and both mental and physical morbidity.
