In addition, they recommended that in none of those signs were present, it can be evaluated also a group of less accurate predictors: the presence of early status myoclonus, high values of NSE at 48–72 h after Return of Spontaneous Circulation (ROSC), an unreactive malignant EEG pattern and the presence of anoxic injury evaluated by brain CT or brain MRI scans [16]. This evidence concerns the gene ENO2 and Myoclonus.
