Introduction: Postural instability is one of the most disabling features of Parkinson's disease.
Objective: To evaluate postural balance in Parkinson's disease.
Methods: Thirty patients with Parkinson's disease were compared with controls using Tetrax™ interactive balance system posturography.
Results: For different positions, patients with Parkinson's disease showed a significantly higher weight distribution index, fall index, Fourier transformation at low-medium frequencies (F2-F4), and significantly lower right/left and toe/heel synchronization versus controls.
Conclusion: Postural imbalance in Parkinson's disease patients is characterized by the abnormalities of weight distribution index, synchronization index, Fourier transformation index, and fall index as measured by Tetrax™ posturography.

The neurological implications of micro- and nanoplastic exposure have recently come under scrutiny due to the environmental prevalence of these synthetic materials. Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of α synuclein (αS) via the enteric nervous system, or the so-called gut-brain axis.

Growing evidence indicates that type 2 diabetes (T2D) is associated with an increased risk of developing Parkinson's disease (PD) through shared disease mechanisms. Studies show that insulin resistance, which is the driving pathophysiological mechanism of T2D plays a major role in neurodegeneration by impairing neuronal functionality, metabolism and survival. To investigate insulin resistance caused pathological changes in the human midbrain, which could predispose a healthy midbrain to PD development, we exposed iPSC-derived human midbrain organoids from healthy individuals to either high insulin concentration, promoting insulin resistance, or to more physiological insulin concentration restoring insulin signalling function.

Aberrant protein misfolding and accumulation is considered to be a major pathological pillar of neurodegenerative disorders, including Alzheimer's and Parkinson's diseases. Aggregation of amyloid-β (Aβ) peptide leads to the formation of toxic amyloid fibrils and is associated with cognitive dysfunction and memory loss in Alzheimer's disease (AD). Designing molecules that inhibit amyloid aggregation seems to be a rational approach to AD drug development.

The subthalamic nucleus is thought to play a crucial role in controlling impulsive actions. Networked among the basal ganglia and receiving input from several cortical areas, the subthalamic nucleus is well positioned to influence action selection when faced with competing and conflicting action outcomes. The purpose of this study was to test the dissociable roles of the dorsal and ventral aspects of the subthalamic nucleus during action conflict in patients with Parkinson's disease undergoing intraoperative neurophysiological recording and to explore a potential mechanism for this inhibitory control.
