fMRI and EEG May Find Signals of Consciousness Earlier in Severe Traumatic Brain Injury Patients
The rate of misclassification of unconsciousness can be as high as 40%. A Mass General team studied using fMRI and EEG to better identify patients with unconsciousness in the ICU.
Imaging Shows Effects of TBI Related to Intimate Partner Violence on Women’s Cognitive Function
Many women who experience intimate-partner violence sustain at least one traumatic brain injury, which can lead to problems with memory, learning and cognitive flexibility. Mass General researchers searched for neural mechanistic evidence of an association between these TBIs and cognitive dysfunction.
Minimally Invasive Electrocorticography, Continuous EEG Do Not Reliably Detect Spreading Depolarizations
Massachusetts General Hospital researchers found that electrocorticography recorded with a conventional subdural strip electrode, electrocorticography recorded with a minimally invasive intraparenchymal electrode, and continuous scalp EEG were all unsatisfactory for identifying spreading depolarizations.
Closing the Health Equity Gap in Neurosurgical Care
Neurosurgeon Theresa Williamson, MD, a Massachusetts General Hospital physician-scientist and medical ethicist, studies decision-making and health care disparities in neurosurgery.
Neural Damage from Severe Abusive Head Trauma in Children Is Age-Dependent
A large-animal model created at Massachusetts General Hospital suggests developmental differences affect the extent and pattern of neural damage after severe abusive head trauma in children. Work is underway to develop age-specific therapies that might limit progression of the damage.
Novel Brain Mapping Confirms Disruption of Ascending Arousal Network in Acute Traumatic Coma
High-angular-resolution diffusion imaging of comatose patients with acute severe traumatic brain injury supports the current concept that coma in such patients is caused by subcortical injury to the ascending arousal network.
