Filter by:This pilot randomized controlled trial will evaluate the feasibility and effectiveness of a mobile neurofeedback intervention for increasing maternal overall well-being, and measuring whether mothers experience any subsequent reductions in trauma symptoms and parenting stress and enhancements in regard to emotional regulation, parenting sensitivity and positive parenting behaviors, as well as infant socio-emotional development and behavioral outcomes (i.e., crying, fussing) among postpartum mothers with symptoms of post-traumatic stress disorder. The investigators hypothesize that mothers who receive the neurofeedback intervention will demonstrate larger decreases in mental health symptoms, greater improvements in emotional regulation and observed parenting behaviors, increased feelings of parenting competency, decreased feelings of parenting stress, and reductions in the potential for child maltreatment than mothers in the control group. The investigators also hypothesize that infants of mothers who receive the neurofeedback intervention will demonstrate less crying and fussiness and higher scores on socio-emotional developmental assessments than infants of mothers in the control group at the posttest interval.
Rhegmatogenous retinal detachment (RRD) is the separation of the neurosensory retina from the retinal pigment epithelium caused by the presence of a break that leads to the passage of fluid from the vitreous cavity into the potential subretinal space. It is a sight threatening disease, affecting largely people 50 years or older, with an annual incidence varying between 6.3 and 17.9 people per 100,000 population, and is unfortunately increasing. Although other surgical options do exist for the repair of primary RRD, pars plana vitrectomy (PPV) has clear advantages and is certainly effective in the treatment of these patients. Several agents are used for intraocular tamponade following PPV for RRD. These agents are either silicone oil (SO) or gases like air, perfluoropropane (C3F8), sulfur hexafluoride (SF6), or perfluoroethane (C2F6). In addition to the complications uniquely peculiar to using SO, research has found out that a reduction in retinal sensitivity on microperimetry was greater in SO tamponade in comparison with gas, as well as poorer visual outcome, microvasculature damage and affection of retinal layers including ganglion cell complex (GCC) in the SO group. Even though many studies were done to compare between SO and intraocular gas tamponades with respect to many aspects, only one study compared the effects SO had on macular vasculature and anatomy in comparison with air and no study at all to date has compared the SO to SF6 gas in terms of retinal vascular changes, correlating them to thinning of GCC and macular sensitivity, which is precisely the main aim of the current study.
Hypnosis and virtual reality are potential tools for treating acute. Nevertheless, the neurophysiological correlates of such tools used together, i.e. 'virtual reality hypnosis' (VRH) (Patterson et al., 2004) remain mostly understudied. This study aims to improve our knowledge and understanding of the dissociation (i.e., a mental separation of components of behaviours that normally would be processed together) occurring during VRH. This is a clinical trial aiming at understanding if the VRH reduces pain during a port-a-cath intervention in oncological patients and if dissociation may explain the pain alteration.
Hypnosis and virtual reality are potential tools in treating acute pain. Nevertheless, the neurophysiological correlates of such tools used together, i.e. 'virtual reality hypnosis' (VRH) (Patterson et al., 2004) remain mostly understudied. This study aims to improve our knowledge and understanding of the dissociation (i.e., a mental separation of components of behaviours that normally would be processed together) occurring during VRH. This is a randomized controlled study that will be conducted on healthy participants. As the final goal is to propose such a tool in the clinical context, a clinical application will also be carried out subsequently. Thus the principal outcome is to study dissociation in the context of VRH from a behavioral and neurophysiological point of view. Secondary objectives aim at identifying factors that influence the dissociative effect seen in VRH, as well as measuring traits of hypnotisability, absorption, immersive abilities, dissociation trait and state, pain, and anxiety levels that might impact the effectiveness of such a tool.
Patients with functional movement disorders (FMD) present with abnormal movements incompatible with symptoms of well-defined neurological disorders and are not associated with structural abnormality of the nervous system. FMD are very common. However, the pattern of care of these patients is highly inconsistent and most patients feel dissatisfied with the treatment they receive. One reason for this unsatisfactory scenario is that there are no generally accepted therapeutic guidelines for FMD. Therefore, treatment strategies are urgently needed. Recent neurophysiological studies suggest common underlying disease mechanism across FMD patients, particularly abnormal allocation of attentional resources. Conceptually, this calls for therapeutic approaches, in which attention re-focusing is trained. In this respect, neuro-physiotherapy (NPT) is based on the physical movement retraining by demonstrating that normal movement is possible, to facilitate patients' confidence into the own movement capacity. Based on the current literature, the investigators suggest that NPT is a feasible and effective treatment options in FMD population. However, the proportion of patients fully accepting and improving from NPT was limited. FMD patients might be more receptive to NPT if additional specialized psychotherapy approaches, e.g., metacognitive therapy (MCT) is offered. MCT focusses on patients believes about their own mind and cognition (metacognition). It explains how dysfunctional patterns of thinking and self-awareness can lead to and maintain FMD and in particular trains patients to consciously (re-)focus their attention away from unpleasant or disturbing mental processes. Thus, the investigators aim to analyze, in addition to NPT only, the feasibility and treatment efficacy of a combination of NPT and MCT. The investigators will apply therapy frequently (2 times 1 hour sessions per week over 10 weeks) and patients will be instructed for an additional home-based training. Effectiveness will be analyzed up to 12 month after the intervention by validated, FMD-specific, blinded video ratings. Importantly, FMD patients have been shown to have the potential for a full recovery if sufficient treatment is applied. Therefore, the therapeutic approaches of the clinical feasibility trial, if successful, are expected to have immediate and strong impact on the care of FMD patients including an improvement in quality of life, and to reduce health care system burdens.

Conversion disorders, also called "dissociative disorders" (ICD-10), or "functional neurological disorders" (DSM-5), are a common condition, with a prevalence of 1-10% in medical and surgical inpatients (Toone 1990), and 10-30% in neurology patients (Carson et al. 2000). They are characterized by the presence of symptoms or deficits affecting voluntary motor, sensory, or sensory functions suggestive of a neurological or general medical condition in combination with psychological factors. Functional neurological disorder is currently a diagnosis of elimination and its treatment remains uncodified. A better understanding of the pathophysiology of this disorder is needed to improve the diagnostic and therapeutic approach to this condition. Identifying new biological markers associated with motor symptoms occurring during the course of the functional neurological disorder would allow clinicians to acquire new diagnostic methods, to improve therapeutic means and their specificity and to highlight possible predictive factors of the clinical evolution of this pathology. At the same time, the identification of biological markers associated with motor symptoms will allow the patient to better understand and accept the diagnosis, and thus to better adhere to the proposed treatment.
Post-operative infectious endophthalmitis is devastating condition that causes a diffuse intraocular inflammation and may lead to blindness. Acute post-operative endophthalmitis usually presented within 6 weeks of intraocular procedure and diagnosis is confirmed by clinical examination and by the aid of B-scan ultrasonography.
The objective of this study is to determine the effects of the ketogenic diet on the frequency of non-epileptic seizures in patients with functional neurological symptoms disorder compared to a healthy diet.
In functional neurological disorder (FND), neurological symptoms are present, such as paralysis, weakness and disturbed sensation of limbs, although clinically no abnormalities can be found. It is a poorly understood disorder with uncertain diagnosis, treatment and prognosis. In this study, the subtype functional paralysis is investigated with advanced neuroimaging techniques that go beyond standard clinical examinations. In previous research on FND, healthy volunteers have generally been used as a control group. However, since people with functional paralysis have similar symptoms to people with spinal cord injuries (SCI), it is intended to compare the three groups to find similarities and differences. With the proposed methods, the goal is to gain a detailed understanding of FND regarding nerve cell metabolism, diffusion pathways and neuronal networks involved in cognitive processes such as motor inhibition (reaction or no reaction depending on situation). Neurophysiological data, clinical assessments and questionnaires are carried out in addition to Magnetic Resonance Imaging (MRI). The aim is to enrol 75 participants in this study, i.e. 25 people with FND, 25 people with SCI and 25 healthy control subjects. The overall goal of the study is to find markers for FND for use in future studies to improve diagnosis and individualise therapy recommendation for both people with SCI and people with FND. Therefore, this study is a relevant step to understand FND and to diagnose this specific disease using objective MRI based diagnostic tools.
