Traumatic brain injury (TBI)
It is an acquired condition that occurs when the brain is damaged. Brain injuries can be the result of a violent blow or a jolt to the head in which the brain collides with the inside of the skull. Less common is traumatic brain injury resulting from an object penetrating the skull and the brain.
Symptoms of TBI can range from mild to severe, and the severity of any disability that may result from a TBI can range as well. At times, communication difficulties arise as the result of TBI. These communication challenges may vary dramatically from person-to-person depending upon the area of the brain that is damaged and how severe that damage is.
