Time,Self and Spontaneous Mental Activities in Patients With Psychotic Disorders

Not Applicable

Terminated

• Conditions: Schizophrenia; Bipolar Disorder

• Registration Number: NCT02765880
• Lead Sponsor: University Hospital, Strasbourg, France

Brief Summary

The main purpose of the study is to examine to which extent abnormalities in the dynamics of neural activities observed in patients with psychosis is related to difficulties at ordering simple visual stimuli and/or personal events.

Primary Outcome Measures

Name	Time	Method
Abnormalities in connectivity during order judgement tasks will be taken as seeds to check whether they account for abnormalities in connectivity at rest, by means of mathematic modelization	After study completion (2 years)

Secondary Outcome Measures

Name	Time	Method
Evaluation of the brain' functional coupling dynamics over time (how neuronal networks and connectivity change over time) during rest.	After study completion (2 years)
- Evaluation of the brain' functional coupling dynamics over time (how neuronal networks and connectivity change over time) during time ordering.	After study completion (2 years)
Comparison of patients with schizophrenia vs. bipolar disorder	During fMRI and EEG sessions
