Every 4 weeks for the first 16 weeks then every 8 weeks for the rest of the study, you will have check up visits. At these visits, you will have a complete physical exam and have blood collected (around 1 tablespoon) for routine tests. You will also have a dietary consultation. Every 8 weeks during the study, you will have either a MRI scan or a CT scan of the brain. If your doctor feels it is necessary, the tests may be done more often or you may have other tests as needed for your care.
