Assessing consciousness with auditory event-related potential during coma recovery: a case study
To observe changes in mismatch negativity (MMN) and P300 in a patient transitioning from a vegetative state (VS) to a minimally conscious state (MCS). One patient with intracerebral hemorrhage and an 8-month disease course was evaluated as being in the VS using the Coma Recovery Scale-Revised. Two weeks after the patient was admitted to the hospital, another evaluation was performed, and the pa...
متن کاملHz Event Related Auditory Potential
Main focus of this paper is an EEG experiment on observing frequency of event related auditory potential in response to series of clicks. Based on the past research, it was expected to observe 40 Hz potential, which was not the case. The experiment was conducted on one subject, and the average observed frequency of 61 Hz could be explained by individual differences. However, an additional step ...
متن کاملTracking the recovery of consciousness from coma.
Predicting the chances of recovery of consciousness and communication in patients who survive their coma but transit in a vegetative state or minimally conscious state (MCS) remains a major challenge for their medical caregivers. Very few studies have examined the slow neuronal changes underlying functional recovery of consciousness from severe chronic brain damage. A case study in this issue o...
متن کاملA hierarchy of event-related potential markers of auditory processing in disorders of consciousness
Functional neuroimaging of covert perceptual and cognitive processes can inform the diagnoses and prognoses of patients with disorders of consciousness, such as the vegetative and minimally conscious states (VS;MCS). Here we report an event-related potential (ERP) paradigm for detecting a hierarchy of auditory processes in a group of healthy individuals and patients with disorders of consciousn...
متن کاملAssessing consciousness in coma and related states using transcranial magnetic stimulation combined with electroencephalography.
Thanks to advances in medical care, an increased number of patients recover from coma. However, some remain in vegetative/unresponsive wakefulness syndrome or in a minimally conscious state. Detection of awareness in severely brain-injured patients is challenging because it relies on behavioral assessments, which can be affected by motor, sensory and cognitive impairments of the patients. Other...
