Deep brain stimulation (DBS) can improve symptoms in well-selected patients with Parkinson's disease. Primary care physicians must take into account many important issues when considering referral for DBS. The Florida Surgical Questionnaire for PD (FLASQ-PD), a 5-section screening tool that can help primary care providers identify appropriate DBS candidates, can be filled out and scored by a general practitioner, advanced clinical nurse practitioner, physician assistant, or trained nurse. Potential candidates who score well on this questionnaire can be referred for presurgical multidisciplinary evaluation at an experienced DBS implanting center.
