The Effects of Exercise on Cognition and Gait in Parkinson’s disease: A Scoping Review

Publication date: Available online 3 October 2018Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Brittany Intzandt, Eric N. Beck, Carolina R.A. SilveiraAbstractCognitive and gait deficits are two debilitating symptoms that occur in Parkinson’s disease (PD). Importantly, a relationship between cognitive and gait deficits exists in PD, suggesting reliance on cognition is increased to compensate for gait deficits and/or deterioration of cognition and gait may share common mechanisms. Rehabilitation strategies targeting one factor could lead to the improvement of the other, presenting a unique opportunity to treat both simultaneously. Gold-standard pharmaceuticals partially alleviate these deficits with significant side effects, highlighting the importance of investigating adjunct therapies like exercise. We critically reviewed the influence of three exercise modalities (aerobic, resistance, and goal-based) on cognition and/or gait in PD. Most studies showed improvements in cognition or gait, yet, a limited number investigated them concurrently. This is the first review examining exercise for cognition and gait in PD. Key gaps in the literature are identified; potential exercise-driven mechanisms for enhancements in cognition and gait proposed, and suggestions for the design of future studies investigating the effects of exercise on cognition and gait in PD.

Mol Med Rep. 2020 May 27;: Authors: Mao Y, Nie Q, Yang Y, Mao G Abstract Retinoblastoma is a common intraocular malignant tumor in children. However, the molecular and genetic mechanisms of retinoblastoma remain unclear. The gene expression dataset GSE110811 was retrieved from Gene Expression Omnibus. After preprocessing, coexpression modules were constructed by weighted gene coexpression network analysis (WGCNA), and modules associated with clinical traits ...

The aim of the present study was to investigate the effects and potential mechanisms underlying resveratrol (RES) in a rat model of streptozocin (STZ)‑induced diabetic mechanical allodynia (DMA). The rat model of DMA was established by the administration of an intraperitoneal injection of STZ. From day 8 post‑STZ injection, rats were administered with an intragastric injection of various doses of RES ...
