EVENT-RELATED POTENTIAL STUDIES OF COMBINED MILD TRAUMATIC BRAIN INJURY/POST-TRAUMATIC STRESS DISORDER IN A RETIRED POLISH ARMY LIEUTENANT COLONEL
Journal Title: Acta Neuropsychologica - Year 2016, Vol 14, Issue 1
Abstract
Background: The extensive Medline search performed allowed us to state that the majority of reports support evidence of information processing abnormalities in patients with Mild Traumatic Brain Injury/Post-Traumatic Stress Disorder.Studies of event-related potentials (ERPs) are the main tool in any real time examination of information processing in miliseconds. Based on the available data, and our own research, we suggest that QEEG and ERPs abnormalities may result in a better understanding of the mechanism by which the symptoms of these disturbances overlap with each other.Case study: The patient, a 57-year-old man, retired Polish Army lieutenant colonel, who had seen active service twice in Lebanon, was diagnosed with Mild Traumatic Brain Injury/Post-Traumatic Stress Disorder, in accordance with the DSM 5 criteria. MR neuroimaging research showed cerebral-subcortical structural dystrophy. The neuropsychological tests confirmed an increasing degree of disturbance within cognitive and emotional processes as well as behavioural disturbances. Through the appliance of QEEG methodology as well as the potentials connected with the event (ERPs) it appeared that: (1) rare low-voltage rapid EEG occured; (2) increased activity in the subcortical areas, (3) weakened activity in the cerebral areas. The patient completely lost cognitive and emotional control which meant that he was unable to function in everyday life.Conclusions: The conducting of ERPs on the patient made it possible to understand the brain mechanisms lying at the basis of the overlapping symptoms of Mild Traumatic Brain Injury/Post-Traumatic Stress Disorder. The appearance of a low-voltage, rapid EEG could possible be a factor enhancing the development of PTSD, particularly in patients who have experienced Mild Traumatic Brain Injury. The results obtained show the need to exclude low-voltage EEG in soldiers despatched to see service in regions of armed conflict.
