Outcome Measures
Primary Outcomes (1)
CBF
ASL is an MRI technique to measure CBF at rest by labeling arterial intravascular water and use as an endogenous tracer. This sequence is performed without injection of contrast or injection of radioactivity
at day 0
Secondary Outcomes (2)
anatomical connectivity
at Day 0
eye-tracking method

Eye tracking and RMI
EXPERIMENTALInterventions
ASL MRI is a non-invasive technique without injection to measure rCBF at rest marking the intravascular water molecules and use it as an endogenous tracer. Premedication, if required, will concern autistic and mentally retarded subjects only.
Diffusion MRI enables the mapping of the diffusion process of water molecules, which allows visualizing anatomical connections between different parts of the brain, noninvasively and on an individual basis. The sequence is acquired following clinical MRI sequences, while the child is still inside the MRI machine, with no further intervention applied.
This sequence is based on the synchronization of fluctuations in the blood-oxygen level dependent (BOLD) signal of different brain regions that work as a network. Therefore this sequence allows for the establishing of maps of funcitonal connectivity.
Eye tracking is a non-invasive method that allows objectifying gaze parameters during presentation of stimuli on a computer screen. Children will be presented with a series of social and no social stimuli and are required to watch it, with no further intervention applied.
Children will be asked to perform certain tasks, adapted for their age.
Eligibility Criteria
You may qualify if:
- Patient diagnosed autist or suspected autist : males and females with the diagnosis of autism based on the following criteria:
- years ≤ age \< 18 years,
- demand for MRI in the etiologic assessment (suspected autism) or MRI control in the treatment (diagnosed with autism)
- obtaining written consent from parents or legal guardians of patients.
- Patients diagnosed with mental retardation or suspected with mental retardation : males and females with the diagnosis of mental retardation using the following criteria:
- years ≤ age \< 18 years,
- demand for MRI in the etiologic assessment (suspected mental retardation) or MRI control in the treatment (diagnosed with mental retardation)
- obtaining written consent from parents or legal guardians of patients.
- Healthy control subjects: males and females:
- years ≤ age \< 18 years
- no known neurological or psychiatric disorder obtaining written consent with parents or legal guardians of volunteers.
- Very young patients suspected of autism: male and female with suspected autism
- months ≤ age \<5 years
