A new test that uses Peripheral Vision Reaction Time (PVRT) is developed for earlier diagnosis and more effective treatment of mild traumatic brain injury (mTBI). mTBI commonly damages the corpus callosum and other centroaxial structures. Study results suggested that the PVRT indirectly measures white matter integrity in the posterior corpus callosum, and therefore diagnoses mTBI. Although most patients with mTBI or concussion fully recover, a significant number do not.
Lingering symptoms may include loss of concentration and/or memory, confusion, anxiety, headaches, irritability, noise and light sensitivity, dizziness and fatigue. Therefore, earlier diagnosis of mTBI is necessary for better management of patients at risk for developing these symptoms. What Is PVRT And How It Diagnoses mTBI The corpus callosum transfers information between the two cerebral hemispheres, and the…
