2 Kempenhaeghe is a leading center of medical expertise, offering diagnosis and treatment to adults and children who suffer from a complex form of epilepsy, a sleeping disorder or neurological learning disabilities. Research & Development of Kempenhaeghe is aimed at development and transfer of expertise. Research questions for our studies originate directly from patient care and are focused on innovation of patient care. Since 00, a strategic collaboration was started with in order to develop novel technologies to improve quality, efficiency, and safety of care in epilepsy, sleep medicine, and neuro-cognitive disorders. And since 04, the Academic Center of Epileptology was set up with Maastricht University Medical Center (Maastricht UMC+). In this overview, examples of innovation projects of Kempenhaeghe with other partners are provided. In addition, a publication list of 04/5 and an overview of ongoing PhD projects are shown. Brain mechanisms of language problem in children with rolandic epilepsy Rolandic epilepsy (RE) is one of the most common childhood epilepsies, and is characterized by relatively mild seizures which typically occur during sleep. In addition, the seizures spontaneously stop before adolescence, and RE has long been considered a benign disease. However, epilepsy is often not only a disease associated with seizures, and in RE children often develop learning difficulties, especially language problems. These language impairments are known from clinical practice and also surface in neuropsychological testing, but it is not clear how this works on the level of the brain. The goal of this project was to find brain abnormalities which might explain these language problem using advanced neuroimaging. Functional and diffusion weighted MRI was used to study functional and structural connectivity of the brain network. dr. ir. René Besseling, assistant lecturer Eindhoven University of Technology, Promotores: prof. dr. Bert Aldenkamp,,3,4, prof. dr. ir. Walter Backes 4 Copromotor: dr. Jaap Jansen 4 3 Ghent University Hospital, Belgium 4 Maastricht University Medical Center Functional MRI (fmri) is a way to study synchronicity of brain activity in distributed brain regions. Classically it is used to see which region(s) activate under a certain task, but it may also be used to investigate which regions are in synch (and thus functionally connected) during rest. We found that the motor areas of the brain are functionally connected with language areas in the left half of the brain. Since in RE the seizures actually originate in these motor areas, this may represent a pathway along which RE can impact language. Indeed, this functional connection between motor and language areas was impaired in children with RE compared to healthy control children. In addition, we used diffusion weighted MRI (DWI) to study structural brain connectivity. DWI exploits the fact that in brain nerve fibers, transport of water occurs primarily along the fibers (and not in perpendicular directions). DWI can be used to reconstruct the course of nerve fibers within the brain (tractography), but also to quantify their microstructural integrity. In line with our functional findings, we found reduced structural connectivity between the motor areas and left lateralized language areas in children with RE. Furthermore, lower microstructural integrity of these connections was associated with reduced language performance in these children. These studies shed light on the brain mechanisms underlying language impairments in children with RE, and provide starting points for therapy development. This work has been published in leading clinical as well as technical journals and has resulted in a PhD thesis Brain wiring and neuronal dynamcics advances in MR imaging of focal epilepsy Figure: fmri of the brain Neurostimulation: towards a deeper insight into the mechanism of action Nowadays, different methods of neurostimulation exist which have shown to be valuable in cognitive neuroscience, neurophysiology, psychiatry and neurology. An example of probably one of the most familiar results is the relief of tremor in patients with Parkinson s disease after deep brain stimulation. Although the clinical benefits have been proven in some disorders, not all patients respond well to neurostimulation. The mechanism of action of different stimulation techniques, and the influence of the stimulation parameters, such as the stimulation frequency, intensity, or location, are not yet known. This knowledge is crucial for further improvement of stimulation techniques in clinical practice, to learn what type of patient responds best to a certain stimulation technique, and to be able to tune the stimulation parameters specifically per patient. This PhD project, started halfway 04, aims at improving the knowledge about the mechanism of action of neurostimulation. Protocols for pilot studies will be conducted in the coming months with the collaborating institutes: Kempenhaeghe, Eindhoven University of Technology, University Hospital Ghent, and the University Hospital Maastricht. Results from the first pilot studies are expected in the beginning of 06.
3 Within Kempenhaeghe, the final, long-term, goal with respect to neurostimulation is to apply the knowledge in a clinical project called NEU3-CA (Neurodegeneration, Neuronal Networks and Neuromodulation in Epilepsy-induced Accelerated Cognitive Ageing). A part of NEU3-CA focuses on the question whether neurostimulation may improve cognitive decline in patients with epilepsy and signs of accelerated cognitive ageing. The results of the PhD project will be helpful to determine the stimulation protocol for NEU3-CA but are definitely applicable beyond this scope, i.e. may be helpful for healthy ageing. ir. Debby Klooster,, PhD student Kempenhaeghe/ One of the core research lines of the Center for Sleep Medicine at Kempenhaeghe is therefore aimed at developing advanced, minimally-intrusive methods to measure sleep and sleep disorders, preferably over longer periods of time in the home environment. Tools will be developed to assess aspects of breathing disorders in sleep (sleep apnea) as well as subjective symptoms in insomnia patients. Research also focuses on using these long term measurements as a feedback for therapy, so highly personalized treatment strategies will become within reach. This research is performed in close collaboration with the faculties of Industrial Design and Electrical Engineering of the Eindhoven University of Technology, as well as several departments at Philips. Recently, funding for 7 PhD s was obtained in this collaboration through an Impulse- grant called Advanced Sleep Monitoring. Collaborators: dr. Anton de Louw,, prof. dr. Bert Aldenkamp,,3,4, dr. ir.

Given this timespan, it is not surprising that many things can go wrong with our sleep. There are many different sleep disorders - about 85 have currently been described - and many people are afflicted by disturbed sleep: up to 0% of the population is estimated to suffer from a sleep disorder. Sleep disorders are typically characterized by subjective symptoms that change over time and under the influence of external behaviors. Objective parameters of sleep - such as sleep depth or sleep efficiency - fluctuate as well. In current clinical practice, these temporal aspects are almost completely ignored. Moreover, the current diagnostic techniques capture only a very limited part of the underlying pathophysiology. In the outpatient Center for Neurological Learning Disorders children (in the range from toddlers to adolescents) with learning problems due to a neurological cause are assessed for a multidisciplinary perspective. Diverse neurocognitive problems are seen e.g., attentional problems as in acquired ADHD but also, problems in information processing, memory or motor function. Since one year we use eye tracking technology alongside neurological and neuropsychological assessment. We use Tobii eye tracking and collaborate in this with Erasmus Medical Center where there is a lot of expertise with this technology. An eye-tracker is a tool that can be attached to a computer screen and measures where and how long a child is looking at the screen. Because the eye-tracker is attached to the screen, the child can move its head unimpeded and is not aware that eyes are being tracked. Data allow analyses of information processing as measured by for example eye movements, duration of looking time, pupil diameter.
4 Together with the department of industrial design of University of Technology in Eindhoven, we developed a diagnostic computer game named Timo s Adventure for a touch screen computer. The game consists of six tasks for children aged 4-8 years to measure different neurocognitive functions, primarily attention, working memory, planning skills, reaction times and time estimation. During the game the child s reactions on pushbuttons and eye tracking data are measured and can be analyzed in collaboration. Besides the results of the different tasks, we collect information on visual search strategies, attention and distraction parameters (e.g., how long does it take for a child to go back to target after being distracted). Eye tracking is a safe and non-invasive method to collect valuable information from scientific and clinical perspective. This information helps in the diagnosis of neurocognitive problems children with neurological learning disabilities. We currently refine the eye tracking technology for example in assessment procedures for evaluating the effect of ADHD medication. drs.
