Need for combined therapy for a rare case of autoimmune autonomic ganglionopathy: A case report.

Background: Autoimmune autonomic ganglionopathy (AAG), formerly known as acute pandysautonomia, is a rare, acquired, antibody-mediated, potentially curable autonomic disorder that presents with diffuse autonomic failure. High levels of anti-ganglionic nicotinic acetylcholine receptor (gAChR) serum antibodies are detected in approximately 50% of AAG cases, confirming the diagnosis.

Case Summary: We present the case of a 68-year-old man who developed autonomic failure gradually over a 2-year period.

The predictive value of social cognition assessment for 1-year follow-up functional outcomes in behavioral variant frontotemporal dementia.

Background And Objectives: Behavioral variant frontotemporal dementia (bvFTD) is characterized by prominent socioemotional deficits that negatively impact daily living. This study aims to identify the strongest socioemotional predictors of functional status at 1-year follow-up and examine whether socioemotional assessment provides additional predictive value for functional outcomes beyond neuroimaging data in bvFTD.

Methods: A total of 78 bvFTD patients were assessed at baseline using a comprehensive social cognition battery and the Functional Activities Questionnaire (FAQ), and were reassessed 1 year later to examine longitudinal changes in their functional abilities.

Iatrogenic Dementia: Providing Insight into Transmissible Subtype of Alzheimer's Disease, Creutzfeldt-Jakob Disease and Cerebral Amyloid Angiopathy.

Within the phenotypic spectrum of Alzheimer's disease (AD), Creutzfeldt-Jakob disease (CJD) and cerebral amyloid angiopathy (CAA), dementia that is attributed to iatrogenic transmission has increasingly gained scientific attention recently. Newly recognized, this treatment-induced form of dementia may result from exposure to certain medical or surgical procedures. The present review aims to explore the distinct features of acquired dementia encompassing a history of potential exposure and relatively early age of onset, highlighting transmission potential with a rather prion-like pattern.

Comparative Genomics Uncovers the Evolutionary Dynamics of Detoxification and Insecticide Target Genes Across 11 Phlebotomine Sand Flies.

Sand flies infect more than 1 million people annually with Leishmania parasites and other bacterial and viral pathogens. Progress in understanding sand fly adaptations to xenobiotics has been hampered by the limited availability of genomic resources. To address this gap, we sequenced, assembled, and annotated the transcriptomes of 11 phlebotomine sand fly species.

CHADS-VASc Score as Predictor of New-Onset Atrial Fibrillation and Mortality in Critical COVID-19 Patients.

Background: Pre-existing and new-onset atrial fibrillation (NOAF) is a common arrhythmia in COVID-19 patients and is related to increased mortality. CHADS-VASc score was initially developed to evaluate thromboembolic risk in patients with AF. Moreover, it predicted adverse outcomes in other clinical conditions, including SARS-CoV-2 infection.

Tumefactive cerebral amyloid angiopathy - related inflammation.

Introduction: Cerebral amyloid angiopathy-related inflammation (CAA-ri) derives from inflammatory response to β-amyloid (Aβ) protein deposition within the cerebral blood vessel walls. We report a case that accentuates those clinical and imaging features that can contribute to raise suspicion for the condition and lead to early treatment initiation.

Case Presentation: A 72-year-old man was referred with one-month history of cognitive decline along with behavioral alterations.

Cerebellar syndrome: do not miss anti-Tr antibodies testing.

We report a case of a 19-year-old woman with a subacute onset of visual disturbance and gait instability in the last three months. The neurological examination revealed horizontal nystagmus in the lateral gaze with a change of phase. The patient also described double vision in various gaze positions, with no clear opthalmoparesis.

Apraxia Patterns for the Differentiation between Alzheimer's Disease and Frontotemporal Dementia Variants.

: Despite the increasing use of biomarkers, differentiation between Alzheimer's disease (AD), behavioral variant Frontotemporal Dementia (bvFTD), and Primary Progressive Aphasia (PPA) remains a challenge. Apraxia is a supportive feature for diagnosing AD but is underrepresented in other dementia types. Herein, we investigated the presence and characteristic profiles of limb, verbal, and non-verbal apraxia in three major dementia types.

Analysis of insecticide resistance and transcriptome assembly of resistance associated genes in the European grapevine moth, (Lepidoptera: Tortricidae).

The European grapevine moth (Denis & Shiffermüller 1776) is an economically important pest of the vine-growing areas worldwide. Chemical insecticides have been used for its control; however, its resistance status is largely unknown in many regions. We monitored the susceptibility of several populations from Greece and Turkey.

Screening for Executive Impairment in Patients with Frontotemporal Dementia: Evidence from the Greek Version of the Frontier Executive Screen.

Objectives: The aim of the present study was to adjust the frontier executive screen (FES) for the Greek population, to develop normative data, and to investigate its ability to discriminate patients diagnosed with frontotemporal dementia from healthy individuals.

Methods: The FES was administered to 142 community-dwelling healthy adults (age: M = 65.9, SD = 8.

Box Lesion Isolation of the Left Atrial Posterior Wall with Radiofrequency Ablation Restricted in Predetermined Lines for the Treatment of Persistent Atrial Fibrillation: The Prognostic Role of Acute Interventional Outcome and Trigger Identification.

The left atrial posterior wall (PW) is known to be a critical substrate for the initiation and perpetuation of atrial fibrillation (AF) and has been explored as a target for catheter ablation, particularly in persistent AF (PerAF). In this retrospective study, we investigate the clinical outcome of patients with PerAF who underwent PW isolation (PWI) restricted in predetermined lines in addition to pulmonary vein isolation (PVI). One hundred consecutive patients (64 ± 9.

Correlates of Functional Impairment in Patients with the Behavioral Variant of Frontotemporal Dementia: A PRISMA-Compliant Systematic Review.

The behavioral variant of frontotemporal dementia (bvFTD) has a devastating effect on multiple domains of daily living. The purpose of this PRISMA-compliant systematic review is to summarize the most important factors associated with functional impairment in this clinical group by critically analyzing the existing literature spanning the period from 2000 to 2023. To be included in the review, a study had to investigate any kind of correlates of functional status in bvFTD patients, using a previously validated instrument of functional assessment.

Detection and Prevention of Mild Cognitive Impairment and Dementia.

Mild cognitive impairment (MCI) is characterized by cognitive deficits alongside essentially preserved competence in activities of daily living [...

Secondary Central Nervous System Demyelinating Disorders in the Elderly: A Narrative Review.

Secondary demyelinating diseases comprise a wide spectrum group of pathological conditions and may either be attributed to a disorder primarily affecting the neurons or axons, followed by demyelination, or to an underlying condition leading to secondary damage of the myelin sheath. In the elderly, primary demyelinating diseases of the central nervous system (CNS), such as multiple sclerosis, are relatively uncommon. However, secondary causes of CNS demyelination may often occur and in this case, extensive diagnostic workup is usually needed.

Metabolic syndrome and cognitive deficits in the Greek cohort of Epirus Health Study.

Background: Metabolic syndrome is considered an important risk factor for cognitive decline and dementia. However, the evidence in middle-aged individuals is still conflicting. The aim of the study was to explore the association between metabolic syndrome and its individual components with cognitive function and to investigate possible interaction between sex, age and genetic predisposition for metabolic syndrome and Alzheimer's disease in a middle-aged Greek cohort.

Functional characterization of cytochrome P450s associated with pyrethroid resistance in the olive fruit fly Bactrocera oleae.

Resistance to pyrethroid insecticides has evolved in Bactrocera oleae populations in Greece, threatening the efficacy of control interventions based on this insecticide class. Here we report the collection of populations from Crete, with resistance levels reaching up to 132-folds, compared to susceptible laboratory strains and show that pyrethroid resistance is substantially suppressed by the PBO synergist, suggesting the involvement of detoxification enzymes. To identify specific candidate genes implicated in resistance, we performed comparative transcriptomic analysis, between the pyrethroid resistant populations from Crete and the susceptible laboratory strains, using both whole bodies and Malpighian tubules.

The cognitive and behavioral correlates of functional status in patients with frontotemporal dementia: A pilot study.

: Frontotemporal dementia (FTD) impinges significantly on cognition, behavior, and everyday functioning. Goal of the present study is the detailed description of behavioral disturbances and functional limitations, as well as the investigation of associations between cognition, behavior, and functional impairment among FTD patients. Given the importance of maintaining a satisfying functional status as long as possible, this study also aims to identify the cognitive correlates of compensatory strategy use in this clinical group.

The Experience of a Tertiary Reference Hospital in the Study of Rare Neurological Diseases.

Rare diseases (RDs) are life-threatening or chronically impairing conditions that affect about 6% of the world's population. RDs are often called 'orphan' diseases, since people suffering from them attract little support from national health systems. The aim of this study is to describe the clinical characteristics of, and the available laboratory examinations for, patients who were hospitalized in a tertiary referral center and finally received a diagnosis associated with a Rare Neurological Disease (RND).

EEG-Neurofeedback as a Potential Therapeutic Approach for Cognitive Deficits in Patients with Dementia, Multiple Sclerosis, Stroke and Traumatic Brain Injury.

Memory deficits are common in patients with dementia, such as Alzheimer's disease, but also in patients with other neurological and psychiatric disorders, such as brain injury, multiple sclerosis, ischemic stroke and schizophrenia. Memory loss affects patients' functionality and, by extension, their quality of life. Non-invasive brain training methods, such as EEG neurofeedback, are used to address cognitive deficits and behavioral changes in dementia and other neurological disorders by training patients to alter their brain activity via operant activity.

Emergence of artistic talent in logopenic variant of primary progressive aphasia: a case report.

The case report covers the investigation of a 59-year-old woman, with the diagnosis of logopenic variant of primary progressive aphasia (lvPPA), who presented de novo visual artistic talent after the onset of language deficits. Similar cases have been described in patients with semantic and non-fluent/agrammatic variants of primary progressive aphasia. However, this is the first related case with lvPPA reported in the literature.
