The role of endothelial dysfunction in the age-related poor prognosis of stroke patients undergoing endovascular treatment.

Background: Age is a well-established predictor of poor prognosis in patients with ischemic stroke (IS) undergoing endovascular treatment (EVT). The endothelium plays a central role in the pathophysiology of IS, and its function can be evaluated using various methods. This study aims to investigate the relationship between endothelial dysfunction, age, and clinical outcomes in IS patients treated with EVT METHODS: Patients with IS treated with EVT were included in the study.

CSF Biomarker-Based Cognitive Trajectories in Parkinson's Disease-Subjective Cognitive Decline.

Objective: Cognitive complaints without objective cognitive impairment in Parkinson's Disease, termed Parkinson's Disease-Subjective Cognitive Decline (PD-SCD), have been associated with cognitive decline. However, its progression is heterogeneous, highlighting the need for improved identification of patients at greater risk for deterioration. This cohort study aims to investigate associations between CSF biomarkers and cognitive decline in PD-SCD.

Approaches for treating neuropsychiatric symptoms in Parkinson's disease: a narrative review.

Neuropsychiatric symptoms in Parkinson's disease (PD) are highly prevalent and profoundly disabling, often emerging even before the onset of motor symptoms. As the disease progresses, these symptoms usually become increasingly impairing and are now recognized as having the greatest impact on quality of life not only for patients but also for caregivers. In recent years, there have been significant advances in the diagnosis and management of neuropsychiatric symptoms.

Genotype-Phenotype Relations for the Dystonia-Parkinsonism Genes , , , , and : MDSGene Systematic Review.

The Movement Disorders Society recommends the DYT/PARK prefix for genes where dystonia and parkinsonism are prominent in approximately half or more of patients. This systematic review explores the genotype-phenotype correlations of , , , , and -recently classified as DYT and historically linked to dystonia-parkinsonism. We searched PubMed and the Human Gene Mutation Database using standardized terms, including English-language, peer-reviewed publications up to February 2024.

Heterogeneity of cognitive progression and clinical predictors in Parkinson's disease-subjective cognitive decline.

Background: Parkinson’s Disease (PD)-associated subjective cognitive decline (PDSCD) is defined as cognitive complaints without objective cognitive impairment. Based on most studies, it is associated with a greater risk of cognitive decline and may represent a prodromal stage of cognitive impairment.

Methods: The main objectives are to identify cognitive progression patterns and clinical predictors of worse cognitive decline within a large PD-SCD cohort with a 4-year followup.

Understanding Endothelial Dysfunction and Its Role in Ischemic Stroke After the Outbreak of Recanalization Therapies.

Despite recent advances in treatment options, stroke remains a highly prevalent and devastating condition with significant socioeconomic impact. Recanalization therapies, including intravenous thrombolysis and endovascular treatments, have revolutionized stroke management and prognosis, providing a promising framework for exploring new therapeutic strategies. Endothelial dysfunction plays a critical role in the pathophysiology, progression, and prognosis of stroke.

Cognitive disorders in advanced Parkinson's disease: challenges in the diagnosis of delirium.

Parkinson's disease (PD) is a neurodegenerative condition that is frequently associated with cognitive disorders. These can arise directly from the primary disease, or be triggered by external factors in susceptible individuals due to PD or other predisposing factors. The cognitive disorders encompass PD-associated cognitive impairment (PD-CI), delirium, PD treatment-associated cognitive side effects, cognitive non-motor fluctuations, and PD-associated psychosis.

Facial emotion recognition deficits are associated with hypomimia and related brain correlates in Parkinson's disease.

Hypomimia is a frequent manifestation in Parkinson's disease (PD) that can affect interpersonal relationships and quality of life. Recent studies have suggested that hypomimia is not only related to motor dysfunction but also to impairment in emotional processing networks. Therefore, we hypothesized that the severity of hypomimia could be associated with performance on a task aimed at assessing facial emotion recognition.

Genotype-Phenotype Correlations for ATX-TBP (SCA17): MDSGene Systematic Review.

Spinocerebellar ataxia type 17 or ATX-TBP is a CAG/CAA repeat expansion disorder characterized by marked clinical heterogeneity. Reports of affected carriers with subthreshold repeat expansions and of patients with Parkinson's disease (PD) with expanded repeats have cast doubt on the established cutoff values of the expansions and the phenotypic spectrum of this disorder. The objective of this systematic review was to explore the genotype-phenotype relationships for repeat expansions in TBP to delineate the ATX-TBP phenotype and reevaluate the pathological range of repeat expansions.

Endothelial NO synthase 786T/T polymorphism increases hemorrhagic transformation after endovascular thrombectomy.

Background And Purpose: This study examined whether the 786 NOS3 polymorphism is associated with the risk of hemorrhagic transformation (HT) in stroke patients with anterior large vessel occlusion (ALVO) treated using endovascular thrombectomy (EVT).

Methods: We performed an observational cohort study that included 118 patients with ALVO who underwent EVT. HT was assessed in follow-up CT and MRI.

Frequency, Predictors, Etiology, and Outcomes for Deep Intracerebral Hemorrhage without Hypertension.

Objectives: Some patients with deep intracerebral hemorrhage (ICH) have a transient hypertensive response and they may be erroneously classified as secondary to hypertension. We investigated frequency, risk factors, and outcomes for patients with deep ICH without hypertension.

Materials And Methods: We consecutively recruited patients with spontaneous ICH attending two Spanish stroke centers (January 2015-June 2019).

Autoimmune GFAP astrocytopathy presenting with remarkable CNS hyperexcitability and oculogyric crises.

The autoimmune GFAP astrocytopathy has been associated with meningoencephalomyelitis that usually responds to glucocorticoids. We report a 20-year-old man that developed an acute and severe meningoencephalomyelitis with remarkable CNS hyperexcitability and oculogyric crises. CSF analysis showed hypoglycorrhachia, pleocytosis, elevated ADA, and CSF-immunofluorescence characteristic of autoimmune GFAP astrocytopathy.

Management of an outbreak of botulism with benign clinical presentation.

Botulism is a life-threatening presynaptic disorder of the neuromuscular transmission produced by the neurotoxin elaborated by the botulinum neurotoxin-producing clostridia. We describe the management of a case series of 14 patients, members of 5 different families that were exposed to home-canned tuna and developed symptoms compatible with a mild clinical presentation of foodborne botulism. The electrophysiological study of the index case represented a reliable diagnostic test as it demonstrated a slight presynaptic dysfunction of the neuromuscular junction.

COL4A1 Mutation as a Cause of Familial Recurrent Intracerebral Hemorrhage.

The COL4A1 mutation is a very rare monogenic cause of small vessel disease related to recurrent intracerebral hemorrhage. We report a family in which the index case presented with two intracerebral hemorrhages in the basal ganglia with severe periventricular leukoaraiosis and a cataract and vascular tortuosity in the ophthalmological study. His twin brother also had severe leukoaraiosis and multiple subcortical microhemorrhages as well as a congenital cataract and vascular tortuosity in the retina.

Cryptococcal meningoencephalitis presenting as cerebral venous thrombosis.

Cerebral venous thrombosis (CVT) is characterized by its variety of neurological manifestations and difficulty in diagnosis. In subacute cases, the main symptoms are secondary to increased intracranial pressure. This condition is associated with an extensive range of medical disorders, but only 2% are caused by a CNS infection in recent series.
