**10. Conclusion**

The electrographic patterns discussed above, such as LPDs, GPDs, LRDA, and B(I)RDs are strongly associated with seizures; this association is well established in ICU patients suffering from AMS. There are however many unanswered questions regarding these abnormal EEG features: do they reflect the severity of the brain injury? Do they actively contribute to its damage and how should we treat them are still largely unknown. Equally not established is their association with long term seizures and the risk of epilepsy.
