Although CDBS has been in use for a long time, very little has been reported on its supposed effects on cognition, particularly in relation to implants in the subthalamic nucleus. The results of the rare studies that do exist are controversial, and in many cases the studies have several design flaws. The present study compared cortical activation during three tasks (action execution, action observation and motor imagery) in PD patients with and without subthalamic implants. The study sample consisted of 36 volunteers, divided into three groups: healthy controls, PD patients with CDBS of the subthalamic nucleus, and PD patients without CDBS. Through a quantitative electroencephalogram assessment, absolute beta power was examined to observe the interaction between group and cognitive motor tasks. The electrodes at sites Fp1, Fp2, F7, F8, F3, Fz and F4, located in the prefrontal and frontal regions, were analyzed and a Group x Task interaction (p < 0.05) was observed for all of them. These findings suggest that CDBS of the subthalamic nucleus is efficient in reducing some of the effects of PD in these study tasks. At the same time, the dysfunctions found in several cortical areas, characteristic of PD, limited the effects of the CDBS. The results of this study suggest that CDBS of the subthalamic nucleus can modulate cognitive-motor aspects of PD.</p>","PeriodicalId":12560,"journal":{"name":"Functional neurology","volume":"34 3","pages":"177-187"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37973372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also set out to compare these responses with those recorded after gait training performed using a walker and with no BWS. The subjects (nearly all with an incomplete spinal cord lesion) were each submitted to two 60-minute experimental sessions on separate days with a 1- week wash-out period between the interventions. The order of the sessions was randomized. Blood samples were collected before and after each experimental trial for measurement of biomarkers. The histone acetylation status and BDNF levels remained unchanged after both interventions. After the treadmill training, the participants showed a strong increase in levels of oxidative stress markers [plasma advanced oxidation protein products (AOPPs), nitrite and thiobarbituric acid-reactive substances] without changes in antioxidant mediators. Instead, elevations in AOPP and nitrite concentrations, in addition to increased levels of glutathione and catalase activity, were found after the walker training. A single bout of gait training, be it conducted on a treadmill with BWS or using a walker without BWS, is not able to alter BDNF levels and histone acetylation status in SCI patients.

This study assesses the current practices of physicians in Lebanon routinely involved in ischemic stroke (IS) management. We conducted a prospective observational study of patients hospitalized at 8 different Lebanese hospitals in the period August 1, 2015 to July 31, 2016, with a diagnosis of acute stroke. Baseline characteristics and data on diagnostic studies, as well as treatments received during hospitalization and at discharge, were collected and analyzed. Two hundred and three strokes/transient ischemic attacks (TIAs) were recorded but only 173 patients (85%) with ischemic events were included in the study. The patients' mean age was 69.8±12.7 years. All underwent brain imaging (CT scan and/or MRI) on admission. All ISs were managed by a neurologist, and patient management included consultation of a cardiologist. Hypertension was the most prevalent risk factor (78.6%), followed by a current cigarette smoking habit (50.3%), diabetes mellitus (42.8%), hypercholesterolemia (39.9%), previous stroke or TIA (17.3%), and atrial fibrillation (14.7%). Only four patients (accounting for 2.5% of the ISs) received thrombolytic therapy. More than 89% of the patients were discharged on at least one anti-hypertensive drug, 89.2% on statins and 37.6% on antidiabetic medications. More than 55% of patients were dependent at discharge, as shown by a modified Rankin Scale (mRS) score of 0-2, whereas 33% were independent (mRS score of 3-5).

The effects of constraint-induced movement therapy (CIMT) have recently been investigated in MS patients. The aim of this randomized single-blind pilot study was to assess the effects of CIMT on upper limb activity, specifically smoothness of movement, in patients affected by progressive MS. Patients affected by MS, and reporting reduced use primarily of one upper limb, were enrolled and randomly allocated to two different groups: a CIMT group, where treatment was performed with the less affected limb immobilized by a splint, and a control group, submitted to intensive bi-manual treatment. All evaluations were performed at baseline (T0) and after two weeks of treatment (T1) by an operator unaware of the patients' allocation. The primary outcome was the difference in movement smoothness, measured by means of a bidimensional kinematic evaluation. Secondary outcomes were: endpoint error and arm trajectory mean speed. Furthermore, patients performed the Hand Grip Strength Test (HGS) and 9-Hole Peg Test (9HPT), for both arms, at both time points. Ten patients with MS (4 males, 6 females; mean age 51.0±7.7 years) were randomly allocated to the CIMT group (n=5) and control group (n=5). There were no significant differences between groups in any of the data assessed at baseline. In the CIMT group subjects, the treatment effect, in terms of movement smoothness, was significant at the more affected limb (p=0.0376). The CIMT group displayed statistically significant improvements, versus the baseline values, in muscle strength (HGS:22.4±8.3 vs 26.0±6.0; p<0.05) and dexterity (9HPT: 31.8±6.1 vs 27.4±4.9; p<0.05) of the more affected limb. A positive, although not significant, trend in terms of muscle strength and upper limb dexterity was observed, for both limbs, in the control group after the two-week treatment. Bi-dimensional kinematic evaluation demonstrated that the CIMT group showed a significant reduction of endpoint error and higher mean speed for the more affected arm; these data are in line with the significant improvements recorded on the HGS and 9HPT. Moreover, in the CIMT group, a non-significant worsening of muscle strength was recorded for the less affected upper limb.</p>","PeriodicalId":12560,"journal":{"name":"Functional neurology","volume":"34 3","pages":"151-157"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37973369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
