Newest firstBackground/Objectives: Multiple system atrophy (MSA) presents a challenging diagnosis due to its clinical overlap with other neurodegenerative disorders, especially other α-synucleinopathies. The main purpose of this systematic review and meta-analysis was to assess neurofilament light chain (NfL) differences in the CSF and blood of patients with MSA versus the healthy control group (HC), patients with Parkinson's…
Background As a prevalent neurodegenerative illness, Parkinson's disease (PD) is associated with serious disability and reduced quality of patients' lives. Therefore, finding new adjuvant treatment approaches that can improve patients' quality of life is crucial. Objectives This study evaluated the impacts of cannabidiol (CBD) on the PC12 cell line and elucidated its mechanism of action, emphasizing the antioxidan…
Overview Cannabinoids have gained increasing attention for their therapeutic potential in treating several neurological conditions, including neurodegenerative diseases, chronic pain, and epilepsy. This review aims to assess the current clinical trials investigating cannabinoids, primarily Tetrahydrocannabinol and Cannabidiol, for neurological disorders. This review will aim to highlight the efficacy, safety, and…
Organophosphate and pyrethroid pesticides are common contaminants in cannabis. Due to the status of cannabis as an illicit Schedule I substance at the federal level, there are no unified national guidelines in the United States to mitigate the health risk of pesticide exposure in cannabis. Here, we examined the change in the state-level regulations of organophosphate and pyrethroid pesticides in cannabis. The medi…
Parkinson's Disease (PD) is the fastest-growing neurological disorder, characterized by the degeneration of dopaminergic neurons. Treatments remain symptomatic, and objective biomarkers for therapeutic response are lacking. This review aims to evaluate the potential of Proton Magnetic Resonance Spectroscopy (1H-MRS) to provide objective and reproducible biomarkers for monitoring treatment response in PD. This syst…
The ultra-high-performance liquid chromatography high-resolution mass spectrometry (LC-ESI-HR-MS/MS) technique was used to characterize the polyphenolic fraction of the hot water infusion (WI) of inflorescences of Cannabis sativa L. Kompolti variety, commercially used for food preparations or cosmetic purposes. On water infusion extract, we applied a multidisciplinary approach, where NMR, MS, in vitro cell-free an…
Introduction Parkinson's disease (PD) is characterized by motor and non-motor symptoms such as tremors, difficulty in initiating movements, depression, and cognitive deficits. The pathophysiology of PD involves a gradual decrease in dopaminergic neurons in the substantia nigra, increased inflammatory parameters, and augmented oxidative stress in this region. Several new therapies aim to promote antioxidant and ant…
The endocannabinoid system (ECS) is a vital biological network essential for maintaining homeostasis and supporting various physiological functions. It comprises cannabinoid receptors, endogenous lipid-based ligands, known as endocannabinoids, as well as metabolic enzymes and associated proteins responsible for regulating their levels within tissues. The ECS plays a central role in modulating processes involving t…
Parkinson's disease (PD) is the second most common neurodegenerative disease, with a rapidly increasing prevalence worldwide. Biomarkers monitoring state and progression are urgently needed, and metabolomics from easily accessible biofluids holds the potential to elucidate pathophysiological underpinnings in PD. Several studies suggested metabolomic differences between patients and controls, but findings are contr…
Many neurodegenerative diseases are associated with immune system disorders, while neurodegenerative processes often occur in inflammatory conditions of the Central Nervous System (CNS). Cannabinoids exhibit significant therapeutic potential due to their dual ability to modulate both neural and immune functions. These compounds have a broad spectrum of action, allowing them to target multiple pathological mechanis…
Background Pathogenic hexanucleotide repeat expansions in C9orf72 are the commonest genetic cause of frontotemporal dementia and/or amyotrophic lateral sclerosis. There is growing interest in intermediate repeat expansions in C9orf72 and their relationship to a wide range of neurological presentations, including Alzheimer's disease, Parkinson's disease, progressive supranuclear palsy, corticobasal degeneration, an…
The increasing use of Synthetic cannabinoids (SCs) in adolescents and young adults poses significant medical and psychiatric risks, and previous reports have been dominated by single-age animal studies. Here, we first investigated the effects of a single exposure of the fourth-generation synthetic cannabinoid 4F-ABUTINACA on cognitive behaviors in adolescent (PND 28-35 days) and adult (PND 49-56 days) male mice in…
GABAA receptors (GABAARs) are no longer viewed as uniform inhibitory switches but as structurally diverse, dynamically regulated ensembles that decode inhibitory signals with remarkable spatial and temporal precision. Their heterogeneity arises not only from the nineteen subunit genes but also from the combinatorial logic of assembly, alternative splicing, stoichiometry, post-translational modifications, and adapt…
The placebo effect has been widely documented across various medical conditions, demonstrating its ability to influence both subjective and objective outcomes. Placebo responses can significantly improve symptoms in these different conditions, such as pain, Parkinson's disease, depression, anxiety, and addiction. Psychological mechanisms, particularly the power of patient expectations, appear to play a central rol…
The molecular imaging of α-synuclein (α-syn) pathology in Parkinson's disease (PD) and related movement disorders is a clinically unmet need. The aim of this study was to discover and characterize in vitro a radioligand for imaging α-syn pathology. A library of 78 small molecules was developed and screened using recombinant α-syn fibrils and brain homogenates from Alzheimer's disease (AD) donors. The selection cri…
Parkinson's disease (PD) is a progressive neurological disorder that affects movement, causing symptoms such as tremors, stiffness, slowness, and balance problems due to the degeneration of dopamine-producing neurons in the brain. Nowadays there is no cure for PD. Alpha synuclein (α-syn) aggregates, which are a hallmark of PD, are known to induce microglial activation, specifically the detrimental M1 microglial ph…
Atypical parkinsonian disorders-progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and multiple system atrophy (MSA)-are rare, rapidly progressive neurodegenerative syndromes characterized by distinct molecular pathologies, heterogeneous clinical phenotypes, and limited therapeutic options. Accurate diagnosis remains a major clinical challenge, especially during early and prodromal phases, due…
Parkinsonian syndromes are characterised by similar motor-related symptomology resulting from dopaminergic neuron damage. While Parkinson's disease (PD) is the most prevalent parkinsonism, we also focus on two other variants, Progressive supranuclear palsy (PSP) and Corticobasal degeneration (CBD). Due to the clinical similarities of these parkinsonisms, and since definite diagnoses are only possible post-mortem,…
Background The progressive legalization and widespread use of cannabis has led to its use as a treatment for certain neuropsychiatric disorders. Traditional epidemiological studies suggest that cannabis use has an effect on some neurocognitive aspects. However, it is unclear whether cannabis use is causally related to common neuropsychiatric disorders. The present study was conducted to illustrate the causal relat…
Atypical parkinsonian syndromes are distinguished from Parkinson's disease (PD) by additional neurological signs and characteristic underlying neuropathology. However, they can be diagnostically challenging, rapidly progressive and are often diagnosed late in disease course. Their different demographic features and prognoses are well studied, but the accompanying cognitive and psychiatric features may also facilit…
