• *Mild traumatic brain injury disrupts the brain’s “default mode” in a way that shows up on functional MRI and correlates with symptoms.
• *Note that the abnormalities in default-mode network connectivity were associated with cognitive dysfunction, depression, anxiety, fatigue, and post-concussion syndrome.

In a small study published in Radioloy mild brain trauma was found to have long term symptoms in default brain functions like memory encoding, consolidation, and environmental monitoring. Also affected was the medial prefrontal cortex associated with self relevance, rapid error identification and social functions. Problems with this network have been seen in Alzheimer’s disease, autism, and schizophrenia.
