Study Summary
Trigeminal neuralgia (TN) is an idiopathic pain disorder that is characterized by episodic attacks of intense facial pain, described as paroxysms of stabbing, electric, or explosive pain, and lasting for a few seconds or longer, often producing a tic-like facial movement, and can occur up to hundreds of times per day. This pain is known to be one of the worst pain conditions that a patient can suffer and has been called the "suicide disease". Given the severity of this disorder, determining the cause becomes essential for finding a cure. This project will study the cause of TN using a translational approach, which means the research project will be completed in both humans and animals. The investigators hypothesize that there are specific areas of the brain and spinal cord that will provide a "signature" center of activity. The study team will use state of the art magnetic resonance imaging (MRI) machines and other non-invasive brain activity measurements, including electroencephalography (EEG) to locate these centers in people with TN before and after their pain has started. Recent studies have investigated the effects of transcranial electrical stimulation (tES) for pain control. Transcranial electrical stimulation (tES) includes transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS). This approach is important because identifying similar regions neural activity will allow for us to study novel therapies in search of the cure for TN and this study has thus both basic and clinical neuroscience significance.
Primary Outcome
Pain will be measured by subjects using a visual analog scale (VAS). The VAS is a psychometric measuring instrument presented as a 100-mm horizontal line anchored on one end with the words "no pain at all" which is 0 and at the other end with the words "worst pain imaginable" which is 100. Subjects will be asked to rate their pain on the VAS from 0-100 once before the stimulation and again after the stimulation is complete. The two scores will be compared to see if there is any reduction in subj
