Active clinical trials for "Dyslexia"

The purpose of the present study is to compare the effectiveness of Rhythmic Reading Training (RRT), a computer-assisted intervention method that combines sublexical reading exercises with rhythm processing, and that of a multimodal intervention comprising different methodology, called 'Abilmente'. All interventions were delivered for a period ranging 1-2,5 months, in 60 minutes biweekly sessions.

PUFAs (poly-unsaturated fatty acids) represent a component of lipids that covers a relevant role in human diet and biological functions such as provision of energy, functionality of cell membranes and tissue metabolism. Fatty acids carbon chains can be saturated (with no presence of double bonds) or unsaturated (with one or more double bonds). PUFAs fall into the unsaturated group, and they can be divided into two classes: omega-3 (n-3) and omega-6 (n-6) fatty acids (FAs). PUFAs are relevant components of cellular membranes, phospholipids, and precursors of eicosanoids, which influence neuronal development and functioning, DHA (docosahexaenoic acid) and AA (arachidonic acid) in fact are involved in cell growth, neural signaling, and gene expression. The main natural dietary source for EPA and DHA is fish oil. It has also been shown how the Magnocellular system, which includes the retinal ganglion cells, the lateral geniculate nucleus (for the visual system, while the medial geniculate nucleus would be involved for the auditory system) of the thalamus, the posterior parietal cortex, various areas visual of the cortex and part of the cerebellum, is sensitive to the contribution of fatty acids through nutrition. A deficit related to the Magnocellular system, specialized in the processing of stimuli with high temporal frequencies and low spatial frequencies, in both the visual and auditory modalities, has been proposed as one of the causes of Developmental Dyslexia. According to this hypothesis, an alteration at the magnocellular level would affect reading by hampering temporal processing of the visual signal and would reduce the quality of the phonological representations due to imperfect acoustic analysis of the incoming phonemes. It is therefore possible to hypothesize that supplementation of PUFA in dyslexic children would improve the functions of the M-system and thus create better conditions to the remediation of reading difficulties, especially through remediation programs specifically tapping visual attention and rapid processing of visual stimuli. The remediation program currently used at IRCCS Medea, Tachidino, based on tachistoscopic, hemisphere-specific stimulation and on training of selective visual-spatial attention, has exactly these characteristics. Hence, the present study aims to test the efficacy of PUFA supplementation before and during treatment with Tachidino.

To show the interest of the association of proprioceptive and orthophonic care of dyslexic children. The assumption is that proprioceptive support by correcting a centrally located spatial localization instability restores the ability to automate. It allows a gain of effectiveness of the orthophonic remediation of the reading of dyslexic children. Interventional comparative study over 9 months, of three modes of care: Speech-language, or proprioceptive, or combined (speech therapy or proprioceptive)

The purpose of the present study is to compare the effectiveness of Rhythmic Reading Training (RRT), a computer-assisted intervention method that combines sublexical reading exercises with rhythm processing, and that of an intervention resulting from the combination of two yet validated treatments for DD, namely, Bakker's Visual Hemisphere-Specific Stimulation (VHSS) and the Action Video Game Training (AVG). Finally, the effectiveness of the administration of only AVG is intended to be compared to other treatments. All interventions are administered for 13 hours over 9 days to a group of Italian students with DD aged 8-12.

The purpose of the study is to evaluate the effectiveness of the combination of Rhythmic Reading Training (RRT), a computer-assisted intervention method that combines sublexical reading exercises with rhythm processing, and transcranial direct current stimulation (tDCS) on reading abilities of a group of Italian undergraduate students with dyslexia. Two experimental conditions (active vs. sham) will be compared. Finally, the effects of the intervention on other cognitive functions involved in the process of reading (i.e., rapid automatized naming, verbal working memory, rhythm perception abilities) will be measured.

Children with dyslexia show a variety of comorbid disorders like behavior and adaptive disorders, hyperkinetic and anxiety disorders. Raising and educating a child with dyslexia is a challenging task for parents. Studies show that parents of children with dyslexia suffer under depressive symptoms and higher parenting stress. In order to support the child's academic development many parents of children with dyslexia practice reading and writing more often and show controlling and maladaptive behavior. As a result learning motivation of the child decreases and later homework situations are influenced in a negative way. Consequently, it is necessary to provide parent training on appropriate behavior with homework and academic exercises, in order to raise parent's competences, reduce parenting stress and promote learning motivation of the child. In the German-speaking area there is a lack of elaborated and evaluated programs for parents of dyslexic children. Therefore, a group program that especially addresses the needs of these parents was devised. The study aims at evaluating the effects of the parent training. We hypothesize that the treatment reduces parenting stress and raises competences of the parents. Forty-one mothers of third graders with dyslexia were randomly assigned to the group-based parent training program (N=25) or a waiting list control group (N=16). Only children who performed in the normal range on the test measuring cognitive abilities (IQ > 70) and who scored below average in at least one test measuring reading or writing (T-Score < 40) were included. Children with significant deficits in hearing or vision, pervasive developmental disorder or genetic disorders were excluded. Data of children and their mothers were collected prior to intervention, directly after intervention and three months after intervention. For investigating training effects at all time points parenting stress and competences in supporting academic development, mastering homework situations and attachment to the child were measured. Parents of the waiting list control group had the possibility to take part in the parent training after the follow-up was completed. The intervention program consists of five two-hour sessions held biweekly. The training lasts about 10 weeks. It is designed for group sizes of three to ten persons. It follows a cognitive-behavioral approach. The training aims at knowledge transfer about dyslexia, raising parent's empathy for the child's difficulties in reading and writing, promoting parent's competencies and self-efficacy in handling dyslexia within the family context and during homework situations, sensitization for opportunities of integrating reading and writing into daily life and reduction of parental stress. The main topics covered are requirements and phases of acquisition of written language, the causes of dyslexia, helpful strategies for managing homework and exercises, facilitation of literacy in everyday life and dealing with dyslexia. Methods used are brief lectures, example cases, group discussions and practice, as well as homework tasks. Written handouts summarizing important topics are given at every session. A benefit of enrolling in the study is that parents get information concerning the academic development of their children. At the moment it is not sure whether parents profit from participating in the training because effects have not been investigated yet. The study takes place at the University of Heidelberg (Children's Hospital) and the Early Intervention Centre in Heidelberg. The study started in January 2012 and is expired to end in October 2014. Participants have been recruited two times, at the beginning of a school year. The timeline for every study flow was similar. Pretests took place in September and October; parent training started in December and lasted until February. Post-Test took place in February and March. Follow-Up measurements were realized from June to July. The study is funded by the Günter Reimann-Dubbers foundation of Heidelberg. The main contact for the study is Bettina Multhauf (M.Sc.

This study aims to determine whether levodopa, in combination with a high frequency training of (grammatical) rules, is effective in boosting learning success in healthy subjects and whether this kind of training in combination with levodopa improves reading and spelling abilities of patients with dyslexia.

The study aims at testing a Neurofeedback (NF) training specifically designed for inducing a functional hemispheric imbalance of the tempo-parietal regions in individuals with dyslexia. A randomized clinical trial aimed at comparing two experimental conditions is described: a) Left theta/beta NF training in combination with right beta/theta NF training and b) sham NF training.

A national, multicenter, randomized, transverse clinical trial, estimating the existence of phonological deficits in children with NF1 children compared with control children without NF1 with the same reading level.

Recent research reveals genetic and symptomatic overlap among children with speech sound disorders (i.e., those who (misarticulate more sounds than would be expected for their age) and children with dyslexia (i.e., those who struggle to learn to read). Children who have speech sound disorders as preschoolers are at risk for the later emergence of dyslexia, a risk that often reveals itself in the form of poor phonological awareness skills during the preschool period. Traditional speech therapy methods focus on articulation accuracy and do not focus on the child's more abstract knowledge of the sound system of the language. The ultimate objective of this research program is to prevent reading disability in children who present with speech sounds disorders. The relative effectiveness of different interventions to help these children achieve age-appropriate phonological processing skills prior to school entry will be investigated. It is expected that a combination of treatment approaches that focus on speech perception skills and vocabulary knowledge will have a superior impact on phonological awareness in comparison with a treatment approach that focuses solely on articulation accuracy.
