NCT02826629
The investigators recently showed that visuomotor integration was significantly altered in schizophrenic patients during: (i) a grip force task (Teremetz et al., 2014), and (ii) a saccadic paradigm (oculomotor task)(Amado et al., 2008). Given this findings, the investigators propose a combined study of oculomotor and grip force control to better characterize the sensorimotor integration deficit. This approach may allow for identification of behavioural biomarkers of vulnerability to develop schizophrenia.
NCT00423943
Patients with schizophrenia have problems in thinking, known as cognitive dysfunction. This appears to be responsible for their difficulties in social and occupational functioning. One particular cognitive function that may be important for schizophrenia is called context processing. This refers to the ability to properly use information in the environment to guide thinking and behavior so that it is appropriate to the present circumstance. Problems with this function may explain why patients with schizophrenia think and act in unusual ways, and often have problems managing aspects of their lives that healthy adults take for granted. This cognitive function depends on a region of the brain called the prefrontal cortex, which shows impaired function in schizophrenia as well. Unfortunately, the biochemical aspects of this dysfunction are presently unknown, and it is not clear whether current psychiatric medications can improve this function. A recent FDA-approved medication that may improve this function is modafinil. Studies in animals and healthy adults show that this medication can improve cognitive functions which are related to context processing. We plan to study the effects of modafinil on context processing and the brain activity that underlies this function. We will use functional MRI and electrophysiology to examine the effects of modafinil, both after a single dose and after sustained (4 week) treatment. We predict that when patients receive modafinil they will perform better on cognitive tests and have improved activity in the regions of the brain that are responsible for these cognitive processes.
