Functional MRI of Cognitive Control in Autism
An observational study of Autism, run by UMC Utrecht at 1 site in Netherlands.
Trial summary
This study aims to investigate the role of fronto-striatal circuits and cognitive control in the perseverative and inflexible behavior that is a defining feature of autism. We hypothesize that deficits in the development of fronto-striatal circuitry may underlie cognitive inflexibility in autism. Read more about this study

About this study
This study aims to investigate the role of fronto-striatal circuits and cognitive control in the perseverative and inflexible behavior that is a defining feature of autism. We hypothesize that deficits in the development of fronto-striatal circuitry may underlie cognitive inflexibility in autism. Specifically, we hypothesize that repetitive, inflexible behavior arises as (1) fronto-striatal systems are capable of learning patterns present in the environment (as in implicit learning paradigms), but are unable to adapt behavior to changing circumstances, related to either (2) decreased ability of basal ganglia to detect violations of expectancy, (3) decreased ability of prefrontal cortex to respond to detected violations, or (4) decreased connectivity of the circuits. We are conducting three functional Magnetic Resonance Imaging (fMRI) studies to address these hypotheses.

Questions about this trial
What is this clinical trial studying?
An observational study of Autism, run by UMC Utrecht at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 20 Apr 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Sarah Durston, Ph.D. (+31 30 250 8161, S.Durston@umcutrecht.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2007.
