Parkinson's disease (PD) is a group of neurological disorders caused by a deficiency of dopamine in a brain structure called substance nigra reticulata (SNr). Deep Brain Stimulation (DBS) of subthalamic nucleus has proved to be a successful treatment for this pathology. DBS modulates the neuronal activity with electrical fields. However, the distribution of the voltage generated in the brain by the stimulating electrodes is not well known. Knowledge of the electrical potential generated by DBS is necessary to find optimal stimulation parameters that deliver the best clinical results and minimal side effects. In this paper, we propose a methodology for estimating the electrical potential based on processing of magnetic resonance image with diffusion tensor (MRI-DT) for specific patient analysis and the finite element method for solution of model equation, in contrast to another similar works where it is employed generic and homogeneous models. Results are consistent with previously outcomes reported in the state of the art and they allow to establish that tensorial model for electrical conductivity is more accurate and detailed to perform DBS simulations, in comparison to generic models with homogenous conductivity.

Objective: Using rhythmic auditory stimulation (RAS) to improve gait disturbance in Parkinson's disease (PD) is an available treatment option, yet a consensus on its effectiveness remains controversial. We summarized the effects of RAS on gait, functional activity and quality of life in PD patients through a systematic review and meta-analysis. Methods: PubMed, Embase, Web of Science, Medline, and Cochrane Library databases were initially searched to identify relevant literature up to August 2021. Next, the methodological quality of eligible comparative studies was assessed by the Physiotherapy Evidence Database Scale. The treatment effects to clinical outcome in relation to gait, motor activities, and quality of life were analyzed. Results: A total of 18 studies consisted of 774 subjects were included in this meta-analysis. Comparing with the control group, RAS had significantly increased stride length (p < 0.001), accelerated gait speed (p < 0.001), reduced the occurrence of freezing events during walking (P = 0.009), achieved an improvement in Unified Parkinson's Disease Rating Scale (UPDRS) II (P = 0.030), UPDRS-III (P < 0.001) and Parkinson's Disease Quality of Life Questionnaire (PDQL) (p = 0.009) scores over an interval of 1-26 months. Conclusion: In this meta-analysis of 18 randomized controlled trials, we have demonstrated that RAS improves the general motor functions (UPDRS-III), particularly in gait, mobility and quality of life, in patients with Parkinson's disease.

Malnutrition is common in neurodegenerative disorders and is associated with a worse prognosis and an increased risk of complications. Factors leading to malnutrition in these patients are: diseased nutrient intake, due to anorexia, dysphagia and other factors, gastrointestinal symptoms, and energy expenditure alterations. Nutritional evaluation and monitoring is mandatory and should be part of regular clinical evaluation. It will help to identify those patients that need specialized nutritional support. In this paper, relevant aspects regarding nutritional evaluation and support in patients suffering from a neurodegenerative disorder are reviewed, including amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease and dementia.
