International researchers have identified nine risk factors linked to a higher risk of symptoms after a concussion that linger for more than a month. The team recruited 803 patients treated for a concussion, and followed up over a month looking for those whose symptoms lingered for 30 days. They say women were more likely to experience lingering symptoms, along with people with a higher BMI, prior diagnosis of headaches, migraines, depression or anxiety. Those who sustained their concussion in a fall, car crash or through abuse were also more likely to have lingering symptoms, along with those who initially presented with a headache, a specific brain function problem such as blurred vision or slurred speech or required multiple CT scans.
