Subtle changes in striatal muscarinic M1 and M4 receptor expression in the DYT1 knock-in mouse model of dystonia.

PLoS ONE, 2019
In early-onset generalized torsion dystonia, caused by a GAG deletion in TOR1A (DYT1), enhanced striatal cholinergic activity has been suggested to be critically involved. Previous studies have shown increased acetylcholine levels in the striatum of DYT1

Basal Forebrain Volume and Concurrent Hallucinations and Mild Cognitive Impairment in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Visual hallucinations (VH) and mild cognitive impairment (MCI) often co‐occur in Parkinson's Disease (PD). Each symptom in isolation is associated with cholinergic basal forebrain (BF) atrophy. However, it is unclear whether BF integrity relates to one symptom preferentially or to their co‐occurrence, and whether this relationship ...

Combined Dysfunction of the Amygdala and Nucleus Basalis Underlies Visual Hallucinations in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Visual hallucinations (VHs) are a common feature of Parkinson's disease (PD) believed to arise from disruptions to the functional architecture supporting sensory integration and attentional control. Across synucleinopathies, increased pathological burden in the amygdala and deficits in cholinergic modulation have been linked to VHs.

Levodopa Disrupts Activity Patterns and Encoding of Movement in Striatal Cholinergic Interneurons of Behaving Mice

Movement Disorders, EarlyView.
Abstract Objectives Levodopa treatment, the gold standard therapy for Parkinson's disease, can lead to levodopa‐induced dyskinesias (LIDs). Recent studies in acute brain slices have implicated the neural dynamics of striatal cholinergic interneurons (CINs) in the pathophysiology of LID, reporting that their discharge becomes more bursty in dyskinetic ...

Functional Magnetic Resonance Imaging (fMRI) Signatures of Progression and Phenoconversion in Prodromal Synucleinopathies

Movement Disorders, EarlyView.
Abstract Background Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) is a prodromal manifestation of synucleinopathies and provides a critical window to identify early markers of progression to Parkinson's disease (PD) and dementia with Lewy bodies (DLB).

Dual role of α7 nicotinic acetylcholine receptors in the retrosplenial cortex for aversive memory acquisition and retrieval

Frontiers in Behavioral Neuroscience
In the retrosplenial cortex (RSC), the role of cholinergic modulation via α7 nicotinic receptors and their involvement in memory is unknown. In recent years, the RSC has been shown to deteriorate in the early stages of Alzheimer’s disease (AD). Likewise,

Vagus Nerve Stimulation in Movement Disorders, from Principles to a Systematic Review of Evidence

Movement Disorders, EarlyView.
Abstract Background The vagus nerve (VN), the principal component of the parasympathetic branch of the autonomic nervous system (ANS), mediates bidirec communication between the central nervous system (CNS) and peripheral organs. Vagus nerve stimulation (VNS), delivered through invasive (iVNS) or non‐invasive (transcutaneous cervical [tcVNS] and ...

Analyzing the ‘Bradykinesia Complex’ in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Bradykinesia is the hallmark sign of parkinsonism. We recently proposed redefining bradykinesia as a complex of motor abnormalities, each reflecting separate pathophysiological elements. Objective To analyze the ‘bradykinesia complex’ in Parkinson's disease (PD) and healthy elderly individuals.

The Second Hit Hypothesis in Animal and Human Dystonia: The Role of Peripheral Nerve Trauma and Spinal Cord Injury

Movement Disorders, EarlyView.
The “second‐hit” hypothesis proposes that both a genetic predisposition and an environmental insult—such as peripheral nerve trauma or spinal cord injury—are required for dystonia development. This review explores how neuroinflammation and maladaptive plasticity, triggered by nerve and spinal cord injury, contribute to dystonia pathogenesis.

Altered Hippocampal Transcriptomic Profile Reveals Cognitive Impairment in Young Metabolically Obese, Normal‐Weight Rats, Prevented by Perinatal Leptin Intake

Molecular Nutrition &Food Research, EarlyView.
Early‐life exposure of rats to high‐fat‐isocaloric diet leads to metabolically obese, normal‐weight phenotype, and impaired cognition. Hippocampal transcriptomic analysis reveals disruption in pathways linked to obesity and cognitive decline, which is mitigated by perinatal leptin supplementation. PBMC share common altered genes with hippocampus, which
