If you have been identified as an appropriate candidate for deep brain stimulation (DBS) after being evaluated by our team, we will work with you to schedule your surgery. You will arrive at The Johns Hopkins Hospital one day before the surgery and will stop taking your anti-Parkinson's medications from 10 p.m. on the day of admission until after the surgery. This helps us observe the benefit of the placement of the DBS, as well as to minimize drug-induced dyskinesias.

If you are undergoing brain surgery, radiosurgery or deep brain stimulation, your Johns Hopkins neurosurgeon may be using fiducial markers to target certain areas for surgical resection or treatment.
Fiducials are small stickers that look like white doughnuts. They are painlessly affixed to your scalp before your operation by a member of your radiology team.
Before your surgery, a CT or MRI scan with the fiducials in place creates a 3-D map of your head. During surgery, the fiducials provide a series of reference points for your surgeon and integrate navigation during surgery with the 3-D map.
This imaging-assisted technique helps your surgeon safely find the way around your brain and precisely locate tumors, targets for deep brain stimulation and other lesions in three dimensions as he or she works, almost like a GPS system.
You may be scheduled to have your fiducials attached a day or two before your surgery. It's important not to disturb or remove them. Ask your surgeon when he or she plans to attach them, since you cannot shower or wash your hair once they are in place. They will be removed once your operation is complete.
