New Radiology Study Finds Distinctive Post-Concussion Brain Injury Patterns in Patients with Depression and Anxiety

The Radiology Society of North America has published a new study that identifies particular white matter brain injury patterns in patients with persistent depression and anxiety following mild traumatic brain injury (concussion or mTBI.) Read More

The verdict is clear: diffusion tensor imaging demonstrates damage to the brain associated with mild traumatic brain injury

The weight of scientific evidence demonstrates that “diffusion tensor imaging” is an effective tool for demonstrating damage to the white matter of the brain associated with mild traumatic brain injury.

The damage typically associated with mild traumatic brain injury (mTBI) is in the axons, the microscopic fiber tracts in the white matter of the brain too small to be seen by conventional tools such as MRI and CT. In fact an individual with a perfectly normal MRI and CT could even be in a coma due to a brain injury. Treatment providers have been left to infer injury from clinical symptoms. However, even the most commonly used clinical tools, such as neuropsychological assessment, are generally seen as insensitive to the subtle, but sometimes life altering, effects of mTBIs. Read More
