Over 70% of chronic pain patients report memory difficulties and fear having unexpected pain. Abnormalities in brain structures associated with emotion and memory, including the hippocampus and amygdala, can be affected by chronic pain. Understanding the relationship between chronic pain, structural brain changes, and cognitive functioning will lead to improved diagnosis, treatment, and outcomes in chronic pain disorders. In this project, the investigators will use advanced brain imaging techniques that assess the structure and function of the brain along with cognitive assessments to examine the overlap between chronic pain and emotion-memory processes. The study team will conduct the study using an excellent model of chronic pain-trigeminal neuralgia, a severe form of facial pain that responds well to surgical treatment. Brain images and cognitive data will be collected from participants before and after surgical treatment for pain. This information will be analyzed and compared with age- and sex-matched healthy individuals. This study will be the first to thoroughly investigate relationships between brain structure and function, cognition (memory, emotion), and promises to impact our understanding of chronic neuropathic pain conditions.",[16,83],"Facial Pain",[16,83,85,86,87],"Emotion","Cognition","Memory","2024-07-23",{"date":90,"type":91},"2024-07-24","ACTUAL",{"date":93,"type":91},"2024-02-12",{"date":95,"type":79},"2029-02-12",{"name":5,"class":6},1]
