This study aimed to characterize the neurophysiological correlates of gait in the human pedunculopontine nucleus (PPN) region and the globus pallidus internus (GPi) in Parkinson’s disease (PD) cohort. Though much is known about the PPN region through animal studies, there are limited physiological recordings from ambulatory humans. The PPN has recently garnered interest as a potential deep brain stimulation (DBS) target for improving gait and freezing of gait (FoG) in PD. We used bidirectional neurostimulators to record from the human PPN region and GPi in a small cohort of severely affected PD subjects with FoG desp...

Authors: Melchionda D, Varvara G, Perfetto D, Mascolo B, Avolio C Abstract Parkinson's disease (PD), which is not only a motor disease, is one of the most frequent neurodegenerative diseases and affects 1.5-2% of people worldwide. The role of its non motor-symptoms is of first importance on quality of life. Speech impairment is considered a part of motor impairment and is widespread in PD where most frequent speech impairment is Hypokinetic dysarthria, a disorder characterized by reduced articulation movements and phonetic monotony. Many PD patients show difficulty in accessing the lexicon related to cognitive impa...

Mitochondrial dysfunction and neurodegeneration have been directly correlated in many neurodegenerative disorders. Parkinson’s disease (PD) in particular has been extensively studied in this context because of its well-characterized association with mitophagy, a selective type of autophagy that degrades mitochondria. Mitophagy is triggered by ubiquitin modification of proteins residing on the surface of mitochondria. Therefore, mitophagy is subject to suppression by deubiquitination. In recent years, many deubiquitinase enzymes (DUBs) emerged as therapeutic targets to compensate hindered mitophagy in PD. It is reason...

In conclusion, our study demonstrated that crocin protected the DA projection neurons in the VTA through activating mTOR, which subsequentl y improved the neural synaptic plasticity of mPFC, and ameliorated depression-like behavior in PD mice.

ConclusionDespite the lack of statistical significance, when assessing the efficacy and safety outcomes for each drug in the evidence network, donepezil appeared to have a more favourable overall benefit/risk profile for patients with DLB. Further comparative trials are required to improve understanding of the true difference between existing and potential future treatment options.

Authors: Lidstone SC, Bayley M, Lang AE Abstract INTRODUCTION: Parkinson's Disease (PD) is a chronic and slowly progressive neurodegenerative disease. Team-based care is required to address and manage the diverse array of motor and non-motor symptoms in PD and related conditions. As the evidence base for the efficacy of non-pharmacological treatment of PD is expanding, many different centers are implementing interdisciplinary models of care with allied health professionals trained in PD. AREAS COVERED: In this review, the authors outline these various models and review the evidence for multidisciplinary approaches ...

PARKINSON'S disease symptoms develop slowly over a long period of time, and could be caused by nerve damage in the brain. One of the more common warning signs of the neurodegenerative brain condition includes a change to the number of times you pass urine each day. Are you at risk of Parkinson's disease?

This week I’m in conversation with Mohanalakshmi Rajakumar. I was fortunate, back in 2012 to come across Mohana’s work and her book ‘Love comes later’. She very kindly graced my Thursday Throng in an interview and since then has gone on to win several awards for her work, including Best Indie Book Award for Romance in 2013. When we talked she explained how she felt about her challenging relationship with writing and gives a fantastic insight into the inner world of the writer. One piece of advice she gave was that a would-be author needs to be very clear about why they are writing in the first place...

Conclusions: HWE deviation of particular variants in relation to global populational HWE, could be, at least in part, associated with the differential susceptibility of specific populations and ethnicities to neurodegenerative diseases. Our data might contribute to the epidemiology and diagnostic/prognostic methods for neurodegenerative diseases.RESUMO Introdu ção: Mitocôndrias defeituosas ou danificadas resultam em alterações do metabolismo energético, equilíbrio redox e dinâmica celular e são, portanto, identificadas como o ponto central da patogênese em ...
