NINDS supports a broad range of basic and clinical research on cerebral aneurysms and other vascular lesions of the nervous system. NINDS funded the International Study of Unruptured Intracranial Aneurysms that guides medical decision-making based on size and location of aneurysms that do not show symptoms. Other research projects include genome-wide studies to identify genes or DNA sequences that may indicate families harboring one type of aneurysm may be at increased risk of another type. Among other research, scientists are studying chromosomes to identify aneurysm-related genes and developing new models to diagnose brain aneurysms based on the presence of molecules that can potentially tell whether there is a high chance of an aneurysm burst.
