Diseases Studied
The Rare Diseases Clinical Research Network is an NIH-funded research network of 20 active consortia or research groups working to advance treatment for diseases that are rare. Use the search tools on this page to find the diseases we currently study. You can reach out to the indicated consortia or research groups for more information on those diseases and studies underway.
This network focuses on clinical research and does not generally support clinical care outside of research activities. To learn about other rare diseases, please visit the Genetic and Rare Diseases Information Center (GARD), which is an NIH program that helps the public find reliable information about rare and genetic diseases. Their staff are specialists. Contact them at 1-888-205-2311 or email GARDinfo@nih.gov.

Brain vascular malformation
Alternative Names: Cerebral Vascular Malformations; Intracranial Vascular Malformations; Occult Intracranial Vascular Malformations; Cereborvascular Anomalies
Disease Category: Brain Vascular Malformations
A group of six identified conditions impacting the blood vessels of the brain which are categorized according to symptoms, severity, and causes. These abnormalities involve direct communication between arteries and veins (arteriovenous malformations) within the brain, or involving the dura or vein of Galen, hemorrhagic dilated vascular spaces (cavernous malformations), dysmorphic veins (venous angiomas), dilated capillaries (telangiectasias), and may be a mixed type. Symptoms include headaches, seizures, strokes, or cerebral hemorrhaging (brain bleeds).
