Epidemiologic study suggests that nicotine reduces the risk of Parkinson's disease (PD) and thus could serve as a potential treatment. In this study, we aimed to investigate the effect of nicotine on the behavioral phenotypes and pathological characteristics of mice induced by human alpha-synuclein preformed fibers (α-syn-PFF). Mice were injected with 5 µg of human α-syn-PFF in the hippocampus while administering nicotine-containing drinking water (200 µg/mL).

Parkinson's disease (PD) is a progressive disorder that affects the nervous system and causes regions of the brain to deteriorate. In this study, we investigated the effects of MR-guided focused ultrasound (MRgFUS) for the delivery of human mesenchymal stem cells (MSCs) on the 6-hydroxydopamine (6-HODA)-induced PD rat model. MRgFUS-induced blood-brain barrier (BBB) permeability modulation was conducted using an acoustic controller with the targets at the striatum (ST) and SN.

Objective: To map evidence on the characteristics, effectiveness, and potential mechanisms of motor imagery interventions targeting cognitive function and depression in adults with neurological disorders and/or mobility impairments.
Data Sources: Six English databases (The Cochrane Library, PubMed, Embase, Scopus, Web of Sciences, and PsycINFO), two Chinese databases (CNKI and WanFang), and a gray literature database were searched from inception to December 2024.
Review Methods: This scoping review followed the Joanna Briggs Institute Scoping Review methodology.
Protective effects of wogonin in the treatment of central nervous system and degenerative diseases.

Wogonin, an O-methylated flavonoid extracted from Scutellaria baicalensis, has demonstrated profound neuroprotective effects in a range of central nervous system (CNS) diseases. This review elucidates the pharmacological mechanisms underlying the protective effects of wogonin in CNS diseases, including ischemic stroke, hemorrhagic stroke, traumatic brain injury, epilepsy, anxiety, neurodegenerative diseases, and CNS infections. Wogonin modulates key signaling pathways, such as the MAPK, NF-κB, and ROS pathways, contributing to its anti-inflammatory, antioxidant, and antiapoptotic properties.
