Lesions known as Lewy bodies (LBs) and Lewy neurites (LNs) characterise brains of Parkinson's disease (PD) patients. Intracellular aggregation of alpha-synuclein (alpha-syn) appears to play a key role in the generation of LBs and LNs. Such aggregation in the presence of redox metals may initiate Fenton reaction-mediated generation of reactive oxygen species (ROS). ROS thus generated may result in cytotoxic mechanisms such as the induction of DNA single-strand breaks.

Parkinson's disease (PD), a degenerative disorder of the central nervous system, is commonly diagnosed using functional medical imaging techniques such as single-photon emission computed tomography (SPECT). In this study, we utilized two SPECT data sets (n = 634 and n = 202) from different hospitals to develop a model capable of accurately predicting PD stages, a multiclass classification task. We used the entire three-dimensional (3D) brain images as input and experimented with various model architectures.

Background: Conventional medical management, while essential, cannot address all multifaceted consequences of Parkinson's disease (PD). This pilot study explores the potential of a co-designed creative arts therapy on health-related quality of life, well-being, and pertinent non-motor symptoms.
Methods: We conducted an exploratory pilot study with a pre-post design using validated questionnaires.

The pathogenesis of Lewy body diseases (LBDs), including Parkinson's disease (PD), involves α-synuclein (α-Syn) aggregation that originates in peripheral organs and spreads to the brain. PD incidence is increased in individuals with chronic renal failure, but the underlying mechanisms remain unknown. Here we observed α-Syn deposits in the kidneys of patients with LBDs and in the kidney and central nervous system of individuals with end-stage renal disease without documented LBDs.

However, to validate IFSH as a reliable imaging biomarker, further replication studies are required. The objective of this study was to investigate associations between IFSH and CSVD, and their potential repercussions, i.
