The study consists of two parts.Objective 1 to document the day by day changes of tinnitus that participants with intermittent tinnitus experience. This objective is aimed for in part 1 of the study. In addition, this part allows the selection of a…
Primary objective of the study:To find out which areas in the brain play a part in the maintenance of tinnitus, and what the roles of those areas are. This will be done using the AEP response in EEG recordings.Secundary objectives of the study:1. To…
The primary objective of the study is to identify the bacterial flora on the abutment in a phylum/species classification. The secondary objectives are to assess the relationships between the commensal skin flora and the flora on the abutment and to…
To examine whether hearing impaired young adults are sensitised to social stress, whether this related to dopaminergic activity and whether theory of mind could mediate the relationship.
Primary: To find out which areas in the brain play a part in the maintenance of tinnitus, and what the roles of those areas are. This will be done using BOLD response fMRI imaging.Secondary: 1. To find out which areas in the brain play a part in the…
The present study intends to perform functional magnetic resonance imaging (fMRI) in order to obtain further insight in effects of selective attention on sensory processing. This study aims to compare subjects with normal hearing to patients that…
The study objectives are to measure the impact of swimming in chlorinated water on the upper and lower airways of children with and without *doctors diagnosed asthma* by means of the following methods: 1.Tympanometry after otoscopy 2.Airway…
Most patients with tinnitus also have a hearing loss. The primary goal of this study is to investigate whether in patients with hearing loss AND tinnitus, the neural response of the brain is enlarged compared to hearing-impaired patients without…
The current study employs functional magnetic resonance imaging (fMRI) to investigate the auditory and limbic areas in tinnitus patients by means of innovative analysis methods that permit the assessment of functional interactions between brain…
With this study we will investigate if our test battery is able to distinguish between children with and without suspection of auditory processing disorders.We also want to investigate the normale development of the auditory system of children…
What is the effect of the distraction hearing screening strategy compared to the neonatal hearing screening strategy on speech and language development and other developmental parameters in children with permanent childhood hearing impairment (PCHI…
The proposed study is designed to investigate the neural substrates of tinnitus using functional Magnetic Resonance Imaging (fMRI). The study is part of the diagnostic and research program *Diagnosis and treatment of tinnitus with emphasis on…
1) Can changes in functional brain networks in patients with and without hallucinations from several psychiatric, neurological, and perceptual disorders be detected? And if so, what is the pattern of change in these diseases?2) Are specific changes…
Primary Objective: To evaluate cytokine levels in blood samples of human subjects with tinnitus and normal hearing, compared to healthy controls.Secondary Objective(s): To evaluate complete blood count measures (neutrophil count, platelet count etc…
The main objective of this study is to compare the brainstem sound-evoked response of the subject groups with different hearing loss laterality and with/without tinnitus. These comparisons may let us know if the function of the human brainstem is…
By acquiring functional MR images and brainstem evoked response audiometry (BERA) from the auditory nuclei in the human brainstem, we expect to observe neurofunctional differences between the subjects with unilateral hearing loss, and subjects with…
Primary Objective: The primary objective is to compare GABA concentrations and receptors availability in the auditory pathway between individuals with tinnitus and two control groups without tinnitus (with or without hearing loss). GABA…
To accomplish this aim we will address the following objectives:1. Define kidney disease heterogeneity within and between families carrying heterozygous COL4A3/COL4A4 pathogenic variants and evaluate hearing loss as non-renal phenotype;2. Analyze…
