(SciTechDaily) – For nearly a century, scientists have recognized that brain trauma, including traumatic brain injuries (TBI), increases the risk of dementia.
However, the exact molecular mechanisms behind this link remain unclear, making it difficult to develop effective treatments to prevent dementia in those affected. Now, researchers at Lund University’s MultiPark research initiative suggest that the brain’s blood vessels could hold the key to future therapies.
Brain trauma often disrupts blood flow in the brain, possibly due to changes in the smooth muscle cells that line blood vessels. These disruptions can lead to secondary brain injuries, further worsening the damage. However, the precise way this process unfolds is still not fully understood. CONTINUE
