Impact des capacités attentionnelles sur l’initiation du pas chez les patients souffrant de la maladie de Parkinson avec freezing de la marche : étude électroencéphalographique

ConclusionLes tâches de résolution de conflit entraînent une altération de l’initiation du pas similaire chez les freezers, non-freezers et témoins. L’électroencéphalographie durant l’ANT combiné à l’initiation du pas semble être pertinente pour une meilleure compréhension de l’influence de l’attention sur l’initiation du pas dans la maladie de Parkinson.

We examined whether Rhy promotes this regulation in bone marrow human mesenchymal stromal cells (BM-hMSCs). Results revealed (i) Rhy modulated biological activity by regulating the mitochondria, N-methyl-D-aspartate receptor subunit, and levels of FGFβ (basic fibroblast growth factor), BDNF (brain-derived neurotrophic factor), OXTR (oxytocin receptor) and ATP (Adenosine triphosphate); (ii) Rhy altered expression level of BM-MSC proliferation/differentiation-related transcription genes; and (iii) interestingly, Rhy amplified the glycolytic flow ratio and lactate dehydrogenase activity while reducing pyruvate dehydrogen...

Parkinson's disease (PD) is the second most common neurodegenerative illness, affecting approximately 1.5 million Americans. Described by many PD patients and families as an insidious “thief,” it progressively diminishes quality-of-life, self-image, and the ability to be independent. The late stage of PD can be protracted with inexorable changes in physical and mental health, altered relationships, and social isolation, all leading to increased suffering. There is significant evidence that many of the greatest needs of PD patients and their caregivers (e.g.

ConclusionThis study showed that PD is a costly neurodegenerative disease that may pose a significant economic burden on patients, health care system and society.

ConclusionHemoglobin levels in PD seem to be closely related to noradrenergic nervous activity and nigrostriatal dopaminergic degeneration. In contrast to expectations, decreased hemoglobin levels were associated with increased whole-body sympathetic nervous activity in PD.

In this study, we used chemoinformatics tools and molecular docking simulations to analyze molecules that have been experimentally tested and bound to α-synuclein, causing neuroprotective or neurotoxic activity, and whose results have been used to select potential natural neuroprotective molecules. We identified 6 potential natural neuroprotective molecules that are similar in their chemical structure to neuroprotective molecules and have a high number of hydrogen bonds with α-synuclein. We expect that these molecules may lead to the design or discovery of new effective treatments for Parkinson's disease.Graphical abstract

Abbott Laboratories is adding some extra firepower to its neuromodulation offerings. The company said last week that its Infinity Deep Brain Stimulation [DBS] device received a nod from FDA to treat Parkinson’s disease symptoms. The newly approved indication specifically calls for the Infinity DBS to target an area of the brain called the globus pallidus (GPi). Abbott said the GPi plays an integral role in the motor function and can be targeted with DBS to improve Parkinson’s disease symptoms not adequately controlled by medication. Abbott said with this approval, the Infinity DBS is now...

Mitochondria are the power plants of the cell. A herd of these bacteria-like organelles in every cell manufacture the chemical energy store molecules that are used to power cellular processes. Mitochondrial function declines with age throughout the body. Evidence suggests that this is due to changes in mitochondrial dynamics that inhibit the quality control mechanisms of mitophagy that are responsible for recycling worn and damaged mitochondria. This loss of miochondrial function is well known to contribute to the progression of neurodegenerative conditions, as the brain is an energy-hungry organ, making this an important ...
