Overall, those with cerebral diseases were older, had high blood pressure and had thicker carotid arteries than those who did not have cerebral small vessel disease. * 15.3% of those with one microbleed lesion had trouble balancing. * 30% of those with more than two microbleed lesions had trouble balancing. * 16% of those with one lacunar infarction lesion had trouble balancing. * 34.5% of those with more than two lacunar infarction lesions had trouble balancing. Researchers found the inability to balance on one leg for longer than 20 seconds was associated with cerebral small vessel disease, namely small infarctions without symptoms such as lacunar infarction and microbleeds.
Cerebral small vessel disease was evaluated using brain magnetic resonance imaging. Participants performed this examination twice, and the better of the two times was used in the study analysis. The maximum time for keeping the leg raised was 60 seconds. To measure one-leg standing time, participants stood with their eyes open and raised one leg. The study consisted of 841 women and 546 men, average age of 67. "Individuals showing poor balance on one leg should receive increased attention, as this may indicate an increased risk for brain disease and cognitive decline." "Our study found that the ability to balance on one leg is an important test for brain health," lead study author Yasuharu Tabara, PhD, associate professor at the Center for Genomic Medicine at Kyoto University Graduate School of Medicine in Kyoto, Japan, said in a news release. 18 in the American Heart Association's journal Stroke. Struggling to balance on one leg for 20 seconds or longer was linked to an increased risk for small blood vessel damage in the brain and reduced cognitive function in otherwise healthy people with no clinical symptoms, according to new research.
