Neurological Soft Signs in Adolescents Linked to Brain Structure Alterations

MRI images of child's brain on the computer monitor with MRI machine blurred in the background

Researchers at Brigham and Women’s Hospital are using neuroimaging to explore the structure–function relationship of neurological soft signs (NSS). They report that NSS in typically developing adolescents are associated with distinct alterations in brain structure that can be objectively quantified using neuroimaging.

Review: Cerebrovascular Injuries in Traumatic Brain Injury

Traumatic cerebrovascular injury (TCVI)—blunt or penetrating injury to the carotid arteries, vertebral arteries, venous structures or a combination—can be a serious sequela of traumatic brain injury. TCVI may be obscured by nearby neurological injury and go undetected for weeks or even years after the initial injury.
