New Research Sheds Light on Stroke Development

Brain Mapping May Lead to Better Preventative Measures


Barcelona, Spain - December 05, 2006 --------- A new study examines the
usefulness of diffusion weighted imaging (DWI), a process of scanning and
mapping the brain, in establishing the relationship between abnormalities in the
cardiovascular system and stroke. This research is helping to determine how a
stroke develops. The study is published in current issue of Journal of
Neuroimaging.


DWI is being used to systematically evaluate patients with crytogenic stroke
comparing patterns of abnormalities in those with and without patent foramen
ovale and atrial septal aneurysms.The study has found that DWI can be beneficial
to doctors in helping to establish relationships between several known causes of
stroke and the likelihood and pattern of their development. The findings will
assist doctors in making therapeutic decisions in individual patients and in
identifying which patients may be at a higher risk for suffering a second
stroke. 


"In these patients, the presence of a specific neurological pattern may provide
the information necessary to isolate the role of certain cardio abnormalities as
causes of stroke," says Estevo Santamarina, MD, lead author of the study. "The
information may one day lead to better preventative therapies for patients at
risk for stroke."
