What this trial studies

This observational study aims to explore the experience of pain by assessing individuals with and without pain disorders. Participants aged 12 and older will undergo a screening process that includes medical history, physical exams, questionnaires, and MRI scans while experiencing various sensations. The study seeks to create detailed phenotypic descriptions of pain disorders and determine eligibility for other NIH research protocols focused on pain. By collecting comprehensive data, researchers hope to enhance the understanding of pain and its clinical aspects.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 12 years and older, both with and without pain disorders.

Not a fit: Patients with acute medical or psychiatric issues that could interfere with study procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment options for individuals suffering from pain disorders.

How similar studies have performed: Other studies have shown success in understanding pain through similar observational approaches, making this a promising area of research.
