From an article titled, MRI Evidence for Altered Venous Drainage and Intracranial Compliance in Mild Traumatic Brain Injury, published this month:
Holy moly. That's interesting, right?In conclusion, the current study provides imaging-based evidence of a chronically reduced cerebral venous drainage through the internal jugular veins, an increased drainage in secondary venous channels with a concomitantly mild decreased intracranial compliance and mild increased intracranial pressure in supine subjects with a history of mTBI.
