COPD Tied to Tiny Brain Bleeds, Study Finds07/19/13
FRIDAY, July 19 (HealthDay News) -- People with the lung
condition called chronic obstructive pulmonary disease (COPD) are
at increased risk for bleeding in the brain, a new study finds.
Researchers looked at 165 people with COPD and 645 people with
normal lung function and found that those with COPD were more
likely to have what are called cerebral microbleeds.
The more severe a patient's breathing problems, the more likely
they were to have microbleeds, according to the study, published
online July 19 in the
American Journal of Respiratory and Critical Care
Cerebral microbleeds are an indicator of disease in the brain's
small blood vessels (cerebral small vessel disease), which is an
important cause of age-related mental decline and disability.
It was known that people with COPD are at increased risk for
large vessel disease, but these new findings "indicate that COPD
might affect both large and small vessels," study author Lies
Lahousse, of Ghent University Hospital in Belgium, said in a
journal news release.
The results also show that methods of preventing cerebral
microbleeds in COPD patients need to be developed, Lahousse
Although the study found a link between having COPD and higher
risk of cerebral microbleeds, it did not establish a
The U.S. National Heart, Lung, and Blood Institute has more
chronic obstructive pulmonary disease.
