<p>Aristotle Voineskos: </p> <hr /> <div>Objectives: <br /> 1. to explore how variants of candidate genes predict different fMRI activation patterns in selected brain regions in patients vs. controls when processing threatening stimuli<br /> 2. to combine autonomic measures, fMRI activation patterns and genetic variants reveal more specific subtypes of PD<br /> 3. to evaluate how repeated exposure to the threatening stimuli changes the fMRI pattern and possibly the electrophysiological response<br /> <br /> Progress:<br /> The study is currently in the recruitment phase. 30 PD with Agoraphobia, meeting criteria of DSM-IV, will be recruited from the Anxiety Disorder Clinic of the CAMH and 20 healthy control subjects recruited by means of a flyer.<br /> <br /> <br /> Key Investigators: Claudia Rothe, Peter Soros, Simon Graham, James Kennedy<br /> <br /> Links: http://www.vepsy.com; http://www.cybertherapy.info (VEPSY: Europe based project to develop virtual reality for treatment of anxiety disorders)</div>

<p>Aristotle Voineskos: </p> <hr /> <div>Objectives: <br /> 1. Use of Diffusion Tensor Imaging (DTI) to determine white matter differences between psychosis (schizophrenia, schizoaffective, etc.) patients and healthy controls across the lifespan<br /> 2. Measure the effect of myelin system genes on FA<br /> <br /> <br /> Progress: 10 participants with psychosis and 10 healthy controls have been recruited to date<br /> <br /> <br /> <br /> Key Investigators: Aristotle Voineskos, Nancy Lobaugh, Benoit Mulsant, Bruce Pollock, James Kennedy, Marek Kubicki, Martha Shenton<br /> <br /> <br /> <br /> <br /> <br /> Links: As data is analyzed over the summer, a link will be placed so that data can be viewed.</div>

<p>Aristotle Voineskos: </p> <hr /> <div>Main hypotheses:<br /> 1. variants of candidate genes predict different fMRI activation patterns in selected brain regions in patients vs. controls when processing threatening stimuli<br /> 2. combination of autonomic measures, fMRI activation patterns and genetic variants reveal more specific subtypes of PD<br /> 3. repeated exposure to the threatening stimuli changes the fMRI pattern and possibly the electrophysiological response<br /> <br /> Sample:<br /> 30 PD with Agoraphobia, meeting criteria of DSM-IV, recruited from the Anxiety Disorder Clinic of the CAMH<br /> 20 healthy control subjects recruited by means of a flyer<br /> <br /> Stimuli: <br /> VR environment for panic disorder from VEPSY (www.vepsy.com www.cybertherapy.info), control stimulus VR environment for social phobia (dinner table, meeting table or similar), baseline stimulus<br /> <br /> VEPSY: Europe based project to develop virtual reality for treatment of anxiety disorders.</div>
