NCT ID: NCT02416856 Completed - Stroke Clinical Trials

Brain Connectivity Supporting Language Recovery in Aphasia

Start date: June 2014
Phase:
Study type: Observational

The integrity of structural connectivity supporting cortical regions in the left brain hemisphere is hypothesized to enable treatment-induced naming recovery in persons with language difficulties after a stroke (aphasia). The investigators will map whole brain connectivity (i.e., the brain connectome) to investigate the role of cortical connectivity in impairment (Aim 1) and recovery (Aim 2) in patients with aphasia undergoing treatment. This information will be used to construct personalized markers of anomia treatment outcome (Aim 3), which may serve as a guide for speech-language pathologists and neurologists when facing patient management decisions.

NCT ID: NCT02395874 Recruiting - Stroke Clinical Trials

tDCS and Speech Therapy to Improve Aphasia

MP-LOGA
Start date: May 2015
Phase: N/A
Study type: Interventional

To study the effect of combined tDCS plus speech therapy compared to sham-tDCS plus speech therapy in subacute stroke patients suffering from moderate or severe aphasia. The patients will be randomized by a computer-generated lot. Assessment will be performed at study onset, after six weeks at the end of the specific intervention and 4 months after stroke onset for follow-up.

NCT ID: NCT02174744 Recruiting - Clinical trials for Pain in Elderly Patients Having Communication Disorders.

Concordance of Pain Detection in Patients by Doloplus® and Algoplus® Behavioural Scales

CALDOL
Start date: January 2014
Phase: N/A
Study type: Observational

The pain of the elderly is often trivialized and ignored in spite of its high frequency: the chronic pain affects 50 % of the elderly living at home, 49 to 83 % of those living in institution and 80 % of this population at the end of life. The evaluation of pain appeals to the same strategy as to the younger subject but with some specificities, related more to the pathologies associated with the ageing than to the real age. For that purpose, the investigators have self-assessment scales as the Numeric Pain Rating Scale which is adapted to estimate acute and chronic pains, but this scale presents a bias because, some patients do not express spontaneously their pain. So behavioural scales were elaborated to solve the difficulties of detection and to care the pain of the elderly. The Algoplus® scale (5 items which takes less than one minute to be completed) whose objective is the observation of behavioural changes caused by the acute pain in elderly having communication disorders. The Doloplus® scale (30 items which allow in few minutes a good evaluation of pain) whose objective is the observation of behavioural changes caused by the chronic pain in elderly having communication impairments. In practice, because of its popularity, the Algoplus® scale is widely used out of the specificity in which it has been validated. Practitioners, worried about this misuse, suggested to Doloplus® group, to test the concordance between the two behavioural scales in order to develop recommendations more targeted. The risk is that the use of the Algoplus® scale may underestimate pain that would have been detected by Doloplus® scale, and lead to under-treatment or non-treatment of pain in elderly having communication disorders. This study aims to establish the concordance between these two scales to generate advices and recommendations to assess efficiently the pain in this vulnerable population. The main objective of this study is to assess whether the use of Algoplus® scale is in good concordance with Doloplus® scale. The secondary objective of this study is to assess the concordance with different levels of Algoplus® pain scale: (0-1), (2-3), (4-5).

NCT ID: NCT02106819 Completed - Cerebellar Diseases Clinical Trials

Emotional Communication Disorders in Cerebellar Disease

Start date: April 2014
Phase: N/A
Study type: Observational

The cerebellum has been linked to cognitive and emotional functions and there is increasing evidence that damage to posterior portions of the cerebellum can result in frontal-executive, visuospatial, and verbal deficits, including dysprosodia, and affective changes including blunting of affect or disinhibited and inappropriate behavior. Based on preliminary clinical observations and tests performed in the investigator's clinic, disorders of emotional communication may also be associated with cerebellar dysfunction. Emotional communication includes the production and comprehension of facial and prosodic expressions and is critical to maintaining positive and supportive relationships. Deficits in emotional communication can have devastating effects on relationships and on quality of life for those affected. Although deficits in affect and prosody have been reported in association with posterior cerebellar disorders, there are currently no studies systematically investigating emotional communication in individuals with cerebellar dysfunction. It is known that the cerebellum has strong connections with the cerebral cortex, especially the frontal lobes, and that cortical damage from stroke or neurodegenerative disease can result in disorders of emotional communication. Impairments in the integrity of cerebellar-cerebral networks from cerebellar disease may produce similar deficits in emotional communication. The purpose of this study is to systematically investigate and describe deficits in emotional communication in a series of patients with cerebellar disease. Participants will be individuals diagnosed with posterior cerebellar degeneration or damage from a non-hemorrhagic infarction, and age-matched neurologically healthy controls. Assessment will include a battery of tests of neuropsychological function as well as tests of emotional communication. Comprehension of emotional facial and prosodic expressions will be assessed as well as production of emotional communication. The expected outcomes will be to identify and describe deficits in production and comprehension of emotional prosodic and facial expressions and to describe the relationship between deficits in emotional communication and cerebellar atrophy with magnetic resonance imaging imaging (MRI) using voxel based morphometry (VBM).

NCT ID: NCT02042235 Terminated - Preterm Birth Clinical Trials

Very Preterm Children With Language Delay and Parent Intervention

EPILANG
Start date: January 2014
Phase: N/A
Study type: Interventional

In studies of children born at term, language delay at the age of 2 years exhibits a spontaneously favourable course in 30 to 50% by the age of 3 years. In France, there is no recommendation for speech therapy before the age of 3 years. However, for term-born children, parent-implemented language interventions conducted during the third year of life have already shown a positive short-term effect on language skills. In these interventions, a skilled interventionist, generally a speech therapist, teaches parents how to use specific language strategies with their child. The investigators' hypothesis is that such parent-implemented interventions would be particularly appropriate at short and medium term for the improvement of linguistic performances in very preterm children, a population with a high prevalence of early language delay. Currently, there is an opportunity to partly nest an intervention trial in a national prospective population-based cohort of very preterm children, the EPIPAGE (Etude EPIdémiologique sur les Petits Ages GEstationnels) 2 cohort, which has included 5 000 babies born alive in France in 2011. This situation provides considerable methodological advantages.

NCT ID: NCT02018614 Recruiting - Pain Clinical Trials

International Validation Study Of The Algoplus Scale In Five Languages

ALGOPLUS LE
Start date: January 2014
Phase: N/A
Study type: Observational

Acute pain is responsible for unnecessary suffering. Among elderly patients, acute pain is frequent and underestimated, especially when these patients have cognitive disorders. The expression of pain is then modified and the conventional tools for evaluating pain cannot be used. Thus the existence of pain must be detected on the basis of a behavioural assessment. It is nonetheless necessary to have the assistance of standardised and validated tools. In France, the Doloplus Group has proposed a scale called Doloplus, validated in January 1999, and is now proposing a new scale for acute pain, Algoplus that has been validated in French (4). Doloplus has been recently translated and validated in 5 languages and an identical methodology will be used in this protocol. Internationally, although several teams are working on the development of scales that can be used for non-communicating elderly subjects, there is as yet no validated tool for acute pain assessment. Considering 1- the lack of tools at an international level and 2- the frequent request from many practitioners worldwide, the Doloplus group has offered to validate the Algoplus® scale in 5 foreign languages, English, German, Spanish, Italian, Portuguese. A rigorous methodology with the help of a statistician will be used in this validation process.

NCT ID: NCT01917864 Completed - Autism Clinical Trials

iPad Application to Treat Prosodic Deficits in Students With Communication Disorders

Start date: July 2013
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the utility of a specialized iPad application designed to treat difficulties with intonation (e.g., melody in voice) in children with autism spectrum disorders (ASD) and other communication disorders.

NCT ID: NCT00723151 Completed - Clinical trials for Developmental Disabilities

Effects of Intensity of Early Communication Intervention

Start date: July 2005
Phase: Phase 2
Study type: Interventional

The purpose of the study is to determine if a more intensive application of communication intervention, i.e. 5 hours per week, will result in more frequent intentional communication acts, greater lexical density, and a better verbal comprehension level than children who receive the same communication intervention only one time per week.

NCT ID: NCT00001308 Terminated - Healthy Clinical Trials

Central Mechanisms in Speech Motor Control Studied With H215O PET

Start date: April 28, 1992
Phase:
Study type: Observational

Positron Emission Tomography (PET) is a technique used to investigate the functional activity of the brain. The PET technique allows doctors to study the normal biochemical and metabolic processes of the central nervous system of normal individuals and patients with neurologic illnesses without physical / structural damage to the brain. Radioactive water H215O in PET scans permits good visualization of areas of the brain related to speech. Most of the PET scan studies conducted have concentrated on learning about how language is formed and decoded. Few studies have been conducted on speech production. This study aims to use radioactive water (H215O) and Positron Emission Tomography (PET scan) to measure blood flow to different areas of the brain in order to better understand the mechanisms involved in speech motor control. When a region of the brain is active, it uses more fuel in the form of oxygen and sugar (glucose). As the brain uses more fuel it produces more waste products, carbon dioxide and water. Blood carries fuel to the brain and waste products away from the brain. As brain activity increases blood flow to and from the area of activity increases also. Knowing these facts, researchers can use radioactive chemicals (H215O) and PET scans to observe what areas of the brain are receiving more blood flow. Researchers will ask patients to perform tasks that will affect speech, voice, and language. At the same time patients will undergo a PET scan. The tasks are designed to help researchers observe the blood flow to brain areas associated with voicebox (laryngeal) functions, movement of muscles in the jaw, tongue, and mouth, and other aspects of motor speech. Special studies will be conducted to evaluate how certain therapies and tasks can draw out symptoms in illnesses in which speech and language are affected. Results of these tests will be used in other studies to evaluate the neurologic mechanisms of diseases like Tourette's syndrome and parkinson's disease.<TAB>
