Filter by:Dystonias represent hyperkinetic movement disorders characterized by protracted muscle contractions, such as to cause torsional movements and anomalous postures in different parts of the body. Although they occur more often in a focal form (blepharospasm, oromandibular dystonia, cervical dystonia, laryngeal dystonia, attitudinal cramps of the limbs) than segmental (involvement of several contiguous muscle groups, e.g. facial muscles and neck muscles), they are nevertheless capable of significantly influencing the quality of life, with consequent social and health costs. Although described as a predominantly motor disorder, the presence of non-motor symptoms in dystonias associated with alteration of the fronto-striatal circuits is increasingly recognized. Neuroimaging studies have highlighted that the striatum and, more specifically, striatal dopamine, is involved in high cognitive processes such as attention, reward-based learning and decision making. Clinical conditions associated with cortico-striatal circuit dysfunction and abnormal meso-striatal or meso-cortical dopamine transmission also appear to influence temporal estimation, delay discounting, showing an impulsive preference for immediate rewards over delayed gratification. Based on these premises, the present project aims to evaluate the cognitive and affective aspects of dystonias, in line with neuroimaging research documenting structural and functional dysfunctions in the respective brain regions.
Based on study literature, the investigators can say that our study aims to give an explanation not only from a behavioral point of view but also with respect to what are the neuronal mechanisms underlying our ability to perceive and analyze our own and others' actions. This is essential to fully understand the complexity of our social behaviors. The knowledge of these mechanisms has a high value and relevant implications for many research fields both within and outside the neurosciences. The project aims to study the neurobehavioral correlates of verbal and non-verbal communication. Through the use of non-invasive behavioral and neurophysiological techniques, the study intends to highlight the neurobehavioral markers that allow to quantify the temporal evolution of communication dynamics in healthy subjects.
The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing, and remediating weaknesses in, numerical skills in children, including those with mathematical learning disabilities (MLD).
Fibromyalgia (FM) is a chronic, complex and disabling clinical entity that has an average global prevalence of 2.7%. It occurs mainly in women in a 3: 1 ratio. It is characterized by persistent generalized pain, fatigue, unrefreshing sleep, cognitive dysfunction and numerous systemic symptoms such as dizziness, migraine, digestive alterations or sensory intolerances. At present there is no pharmacological treatment with specific indication for FM. Usually, non-curative treatments are recommended that alleviate the symptoms of the patients and improve their quality of life and functionality. Many studies have shown cognitive impairment in FM patients compared to control groups, and FM patients mainly show problems with working memory processes and / or in their attentional and executive domains, as well as in speed of speech. processing (BD Dick, Verrier, Harker, & Rashiq, 2008; Glass, 2009; Tesio et al., 2015; Williams, Clauw, & Glass, 2011). Many patients with FM have little understanding of their condition, leading to maladaptive pain cognitions and coping strategies. Current research has suggested the use of physiotherapy and rehabilitation in addition to cognitive patient education in the treatment of fibromyalgia. This study aimed to explore the effectiveness of pain neuroscience education in patients with FM. Therefore, this research aims to analyze the effectiveness of the neuroscience education program on pain in executive functions and the intensity of pain in patients with FM.
Parkinson's disease (PD) is characterized by bradykinesia, rigidity, and tremor. Several scientific pieces of evidence, based on the use of kinematic techniques, have allowed quantifying objectively the alterations of the voluntary movement in the different stages of the disease. In recent years, several studies using transcranial magnetic stimulation (TMS) techniques, have also shown abnormalities in neurophysiological parameters of the primary motor cortex (M1) in patients with MP, in particular, a reduction in cortical excitability and synaptic plasticity of M1. In addition to the central role played by a dopaminergic deficit in MP, recent evidence suggests a possible involvement of the neurotransmitter glutamatergic system. In the present monocentric observational study, the investigators propose to assess possible correlations between polymorphisms of metabotropic glutamate type 3 receptors (mGlu3), clinical evaluation scales, alterations of kinematic motion parameters and neurophysiological parameters of M1.
In this trial, the investigators are going to investigate the improvement of cognitive brain domains after ingestion of omega 3 products that have high concentrations of DHA, Docosahexaenoic acid, and EPA, Eicosapentaenoic acid, in comparison to control group young healthy adults. The study will assess the improvement by computerized testing by their reaction time before and after the intervention. The researchers will follow the scientific and ethical regulations prevent any harmful effect on recruited subjects.
Motor imagery is defined as a dynamic mental process of an action, without its real motor execution. Action observation training consists of watching an action performed by someone else. The primary objective of this study was to evaluate the effects of motor imagery and action observation combined with a hand grip strength program on strength gains in asymptomatic participants. The secondary objective was to assess the influence of motor imagery and action observation training combined with a hand grip strength program on electromyographic activity and intramuscular oxygenation of the forearm muscles.
Phase I study to evaluate the excretion of radioactivity, the metabolic profile, pharmacokinetics, safety and tolerability following a single oral administration of [14C]AZD2423 in healthy male volunteers aged 50 to 65 years (inclusive).The purpose of this study is to investigate how and how quickly AZD 2423 or its break down products are excreted by analysing blood, faeces and urine samples collected during the study.
