Title: Periodic EEG patterns in the Intensive Care Unit (ICU): Definition, recognition and clinical significance


Periodic electroencephalographic (EEG) patterns are fre-quently recorded during ICU EEG monitoring in patients with Altered Mental Status; these EEG features represent electrical discharges, ictal in appearance, occuring at regular intervals. They are known as Lateralized Periodic Discharges (LPDs), Bilateral Independent Periodic Discharges (BIPDS), Generalized Periodic Discharges (GPDs), Continuous 2/s GPDs with Triphasic Morphology or Triphasic Waves (TWs) ,and Stimulus Induced Evolving Lateralized Rhytmic Delta Activity or Si-Evolving LRDA (previously SIRPIDS); other periodic, rhythmic patterns are Occasional frontally predominant brief 2/s GRDA (FIRDA previously), Lateralized rhythmic delta activity (LRDA) and Brief potentially ictal rhythmic discharges or B (I)RDs. The role of most (not all) of these EEG patterns is contro-versial; there is no consensus on which patterns are associ-ated with ongoing seizure injury, which patterns need to be treated, and how aggressively they should be treated. Many authors consider these patterns as an unstable state on an ic-tal-interictal EEG continuum; the aim of this presentation is to gain knowledge of these EEG features, show their asso-ciation with known neurologic pathologies/syndromes and the best way 
to manage them.

Dr Mesraoua is a member of the American Academy of Neurology , the Eu-ropeen Academy of Neurology ,the American Epilepsy Society and the Ca-nadian Epilepsy society.

Dr B.Mesraoua main interests are Epilepsy ,PNES, Electroencephalography  and Clinical Neurology;

Dr Mesraoua main objectives are to encourage frequent gathering of the epi-leptologists/neurologists from the MENA region and the rest of the world , promote Epilepsy Teaching in the MENA Region, and encourage multicenter studies involving neurologists and epileptologists in the MENA region. 

Dr Mesraoua is the recipient of two research Grants, as the Lead Principal Investigator (750.000 USD and 250.000 USD) from the Qatar National Re-search Fund (QNRF) and Hamad Hospital Internal Research Grant (IRGC) , on the following topics : “Continuous EEG Monitoring in the ICU “ and on “Alpha-lactoalbumin , proof of concept in the treatment of epilepsy” .

Dr Mesraoua is the author and co-author of many peer reviewed publications ,editor of one book on status epilepticus and eight book chapters in the field of Epilepsy and Clinical Neurology
