Spatial neglect is a common cognitive disorder in stroke patients, characterized by a lateralized deficit in attention and intention. This research focuses on defining norms for tests to assess spatial neglect. The norms correspond to the results obtained in a population free of any disorder that could have an impact on test performance. These results can vary in a normal, non-pathological way, with certain parameters such as age, sex, laterality or level of education. Defining these norms in healthy volunteers is therefore essential for interpreting results in patients suspected of spatial neglect, and in particular for defining pathological thresholds above which the diagnosis of spatial neglect can be retained. To answer the research question, we plan to include 210 people with no central neurological disease (stroke, epilepsy and multiple sclerosis in particular), in a single-center study in the neurovascular department of the Raymond-Poincaré hospital (Garches). The 210 subjects will be divided into 10-year age groups, from 20 to 89 years, with the recruitment of 30 participants per age group (15 men and 15 women): 20-29 years, 30-39 years, 40-49 years, 50-59 years, 60-69 years, 70-79 years, 80-89 years.
NCT04966000
Preliminary data will be collected about which individuals with spatial neglect from right hemisphere stroke (aiming vs perceptual neglect) improve with Prism Adaptation Training and if there is a particular pattern of damage in the brain that predicts both the type of neglect experienced and whether neglect is improved following Prism Adaptation Training
NCT02680730
Purpose: A research project will be conducted at the ADD ("Attention Deficit Disorder") Centre and Biofeedback Institute of Toronto to evaluate the feasibility of the Listening Project Protocol (LPP) intervention in individuals with difficulties with autonomic and/or behavioral regulation. The LPP is designed as a "neural exercise" to reduce auditory hypersensitivities, to improve auditory processing of speech, and to improve behavioral state regulation. These improvements should translate into increase feelings of safety and calmness, thereby promoting improvement in social behavior. Participants: 30 participants, males and females between ages 7-55 years, will be recruited for the study. Participants will be patients at the ADD Centre and Biofeedback Institute of Toronto. Procedures: Participants will be divided into 1 of 2 groups (1:1 ratio). Both groups will have a pre-intervention assessment #2, intervention, 1 week post intervention assessment and 1 month post intervention assessment. Group 2 will have an additional pre-intervention assessment session #1 (1 week previous to pre-intervention assessment #2) to assess the stability of the measures prior to starting the intervention. Pre-, post-, and 1 month followup assessment will include parent and/or self-report questionnaires, and measures of the individual's auditory processing ("SCAN"), affect recognition ("DARE" Dynamic Affect Recognition Evaluation), heart rate, prosody, "RSA" respiratory sinus arrhythmia (derived from non-invasive ECG recording), and middle ear transfer function ("MESAS" - Middle Ear Sound Absorption System).
NCT03468660
Older people experience great difficulty understanding speech, especially accented English, and this problem is expected to increase with the influx of immigrants who provide services to the elderly population. The research examines the underlying factors that contribute to older listeners' difficulty understanding accented speech, including those associated with age-related hearing loss, changes in processing in auditory pathways in the brain, and general cognitive decline. The investigation also evaluates the efficacy of training strategies to improve understanding of accented English by older people. Outcomes of this research are expected to improve communication between senior citizens and those with whom they interact daily, and thereby improve quality of life for the older segment of the Nation's population.
NCT04573413
Randomized Controlled Trial (RCT) aiming at assessing the efficacy of a novel rehabilitation protocol, based on repetitive transcranial magnetic stimulation (r- TMS) in combination with a conventional cognitive treatment (CCT). The protocol will be statistically compared to the same CTT administered without the r-TMS in a sample of traumatic brain injury patients (age between 18 and 80 years) with left hemispatial Neglect.
NCT02225041
The purpose of this study is to determine the relationships between sedative exposure during pediatric critical illness and long-term neurocognitive outcomes. We will test for drug- and dose-dependent relationships between sedative exposure and neurocognitive outcomes along the early developmental spectrum and will control for baseline and environmental factors, as well as the severity and course of illness. Hypotheses: 1. Greater exposure to benzodiazepines and/or ketamine will be associated with lower IQ even when controlling for severity of illness, hospital course, and baseline factors. In addition, benzodiazepines and/or ketamine will negatively affect other aspects of neurocognitive function. 2. Younger children exposed to benzodiazepines and/or ketamine will have worse neurocognitive outcomes than older children with similar sedative exposure and severity of illness.
NCT03358160
The aim of this study is to investigate the possible effects that a motor limitation at the peripheral level might have on the ability to visually discriminate others' actions. Previous literature has shown that specific motor skills (motor expertise) facilitate the visual discrimination of domain-specific actions, and that these motor experts' superior abilities might be mediated by areas not only responsible for the visual recognition of movements (as it happens in non-expert subjects) but also involved in motor planning. Similarly, impairment in the motor system due to neurological damage modulates not only the ability to perform movements but also the ability to discriminate and predict the temporal course of observed actions. Based on these findings, it has been hypothesized that the motor representations of gait, despite being a hyper-learned motor pattern, might be subjected to modification as a result of an impairment of walking caused by a peripheral functional limitation in the lower limbs as the one characterizing orthopaedic patients who underwent a surgical operation for total knee arthroprosthesis. In this protocol, patients are thus required to perform visual discrimination tasks based on the observation of movements performed with either the upper or lower limbs, and their performance is expected to correlated with their functional impairments in movement execution. These results would indicate that the (in)ability to perform a movement might have an impact on its representation at the central level and on internal motion simulation capabilities, which also influence the ability to visual discriminate others' actions through action-perception transfer: this would suggest that rehabilitation in orthopaedic patients should take into account (and restore) such a central impairment in motor representations.
NCT01101659
The objective of this study is to investigate whether JNJ-40411813 versus placebo reduces psychosis-like symptoms, induced by infusion of a low dose of ketamine. Effects of JNJ-40411813 on ketamine-induced symptoms will be evaluated about 3 hours after a single oral dose when the concentration of JNJ-40411813 in the blood is at its maximum and up to 24 hours after dose administration to assess the duration of a potential JNJ-40411813 effect.

The purpose of this study was to determine the effects of hormone replacement therapy (HRT) on hearing in post-menopausal women.
