Therapeutic Potential of Agmatine in Essential Tremor Through Regulation of Lingo-1 and Inflammatory Pathways.
Brain Behav
January 2025
Neuroscience Research Center, Institute of Neuropharmacology, Kerman University of Medical Sciences, Kerman, Iran.
Purpose: Essential tremor (ET) is a prevalent movement disorder, yet current therapeutic options remain limited. Emerging evidence implicates leucine-rich repeat and immunoglobulin-like domain-containing protein (Lingo-1) and neuroinflammation in the pathophysiology of ET. This study aimed to investigate whether agmatine, a biogenic amine neuromodulator attenuates tremors and modulates the expression of Lingo-1 and proinflammatory markers in a rodent model of ET.

Objective: To explore the clinical manifestations and genetic characteristics of a child with Leukoencephalopathy with ataxia (LKPAT) caused by a CLCN2 gene variant.
Methods: A retrospective analysis was conducted on the clinical data of a child admitted to Hunan Children's Hospital in June 2024 due to "intermittent convulsions for 13 days". Peripheral blood samples were collected from the child and his parents for whole exome sequencing, followed by Sanger sequencing validation and pathogenicity analysis of candidate variants.
Locus Coeruleus Degeneration in Essential Tremor With Mild Cognitive Impairment: A Neuromelanin MRI Study.
CNS Neurosci Ther
January 2025
Department of Neurology, the Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, China.
Objective: Our aim was to research the neuromelanin-sensitive magnetic resonance imaging (NM-MRI) features of the locus coeruleus (LC) in essential tremor (ET) patients of various cognitive states and to explore the relationships between these features and cognition.
Methods: We recruited three groups of participants, including 30 ET patients with mild cognitive impairment (ET-MCI), 57 ET patients with normal cognition (ET-NC), and 105 healthy controls (HCs). All participants underwent MRI scanning and clinical evaluation.
Essential tremor with tau pathology features seeds indistinguishable in conformation from Alzheimer's disease and primary age-related tauopathy.

Neurodegenerative tauopathies are characterized by the deposition of distinct fibrillar tau assemblies, whose rigid core structures correlate with defined neuropathological phenotypes. Essential tremor (ET) is a progressive neurological disorder that, in some cases, is associated with cognitive impairment and tau accumulation. In this study, we explored tau assembly conformation in ET patients with tau pathology using cytometry-based tau biosensor assays.

Parkinson's disease arises from the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to motor symptoms such as akinesia, rigidity, and tremor at rest. The non-motor component of Parkinson's disease includes increased neuropathic pain, the prevalence of which is 4 to 5 times higher than the general rate. By studying a mouse model of Parkinson's disease induced by 6-hydroxydopamine, we assessed the impact of dopamine depletion on pain modulation.
