Traumatic and Non Traumatic Brain Injuries

There are two types of brain damage: traumatic and atraumatic. Traumatic brain injury caused by external forces such as car accidents, occupational accidents, falls, violence; however, internal forces are the cause of atraumatic brain injury such as stroke, infection, and brain tumor. "Dizziness, headache, carelessness, memory loss and fatigue are often seen as part of post-patient post-traumatic experiences after TBI" (M.C. WESTCOTT 1 and D. P.ALFANO 2, 2005).

TBI is one of two subsets of acquired brain injury (brain injury occurring after birth); the other subset is atraumatic brain injury without external mechanical forces (such as stroke and infection) . All traumatic brain injuries are head trauma, but the latter term may also refer to damage to other parts of the head. However, the terms head injury and brain damage are often used interchangeably. Similarly, brain damage belongs to the classification of central nervous system injuries and nerve damage. In neuropsychology research literature, the term "traumatic brain injury" is generally used to refer to non-penetrating traumatic brain injury.

Traumatic brain injury (TBI) is a silent epidemic. Mild traumatic brain injury (mTBI) causes brain injury and causes electrophysiological abnormalities seen in electroencephalogram (EEG) recording. The purpose of this short review is to discuss the importance of EEG findings in traumatic brain injury. Related articles issued during the period of 1996 - 2016 were retrieved from Medline (PubMed). The keywords are English including "traumatic brain injury", "brain wave" and "quantitative electroencephalogram". 460 articles were found, 52 articles were analyzed, 13 articles were selected. After TBI, the EEG shows that the posterior upper rhythm slows down, the diffuse property θ slows down, may return to normal within a few hours, or may slowly resolve within a few weeks. There is no clear EEG or quantitative brain wave (qEEG) characteristics for mild traumatic brain injury

In this brief summary, we describe the various EEG findings seen when head injury leads to brain damage. As the brain is damaged, several observations can be seen in the EEG as a change in coherence or correlation, from spectral changes related to white matter or gray matter damage to changes in "connectivity".
