All information provided is confidential.

If you meet criteria for any of our studies, you will be asked to return for one or more MRI scans and one or more PET scans. You will also be asked to perform some tests on a computer to assess cognitive functions such as memory and decision-making. You will be paid the following for each procedure you take part in.
