However, it is unclear whether USN affects verticality among patients with PB. We aimed to clarify the characteristics of verticality among PB, with and without USN. The study included 43 patients with right hemisphere stroke, including 12 without PB or USN, 10 with only USN, 10 with PB only, and 11 with PB and USN, and 15 age-matched healthy individuals. The subjective visual vertical (SVV), subjective postural vertical with eyes closed (SPV), and subjective postural vertical with eyes open were assessed. Under each condition, the mean (tilt direction) and standard deviation (variability) across trials were calculated. The variability of SVV was significantly greater among patients with only USN (6.9°±5.9°) or those with PB and USN (7.6 ± 4.3°). On SPV, the contralesional tilt was significantly greater, with higher variability, in patients with only PB (-2.2°±1.1° and 6.3°±1.4°, respectively) and those with PB and USN (-2.1°±2.0° and 6.6°±2.0°, respectively) than in the other groups. In patients with PB, SVV differed ...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

CONCLUSIONS: Young adult IS patients in Korea exhibit low awareness and poor management of their risk factors. Although the short-term outcome was relatively favorable in those patients, having SLE was associated with unfavorable outcomes. More attention needs to be paid for improving awareness and controlling risk factors in this population. PMID: 33029967 [PubMed]

Abstract As the global population ages, the incidence of neurodegenerative diseases has risen. Furthermore, it has been suggested that depression, especially in elderly people, may also be an indication of latent neurodegeneration. Stroke, Alzheimer's disease (AD), and Parkinson's disease (PD) are usually accompanied by depression. The urgent challenge is further enforced by psychiatric comorbid conditions, particularly the feeling of despair in these patients. Fortunately, as our understanding of the neurobiological substrates of maladies affecting the central nervous system (CNS) has increased, more therapeutic ...

Abstract Action selection (AS), or selection of an action from a set of alternatives, is an important movement preparation process that engages a frontal-parietal network. The addition of AS demands to arm training after stroke could be used to engage this motor planning process and the neural network that supports it. The purpose of this case series is to describe the feasibility and outcomes associated with task-oriented arm training aimed at engaging the AS behavioral process and the related neural network in three individuals with chronic stroke. Three participants with mild to moderate motor deficits complete...

Conclusions: The integrity of the intra- and interhemispheric connections might be related to different processes of motor recovery dependent on the BDNF genotype. Thus, the BDNF genotype may need to be considered as a factor influencing neuroplasticity and functional recovery in patients with stroke. This trial is registered with http://www.clinicaltrials.gov: NCT03647787. PMID: 33029116 [PubMed - in process]
