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 Boulenouar Mesraoua is Senior Consultant Neurologist at HMC , Neuro-science Department ,and Associate Professor of Clinical Neurology at WCMC-Q; He graduated as an MD from Algeria then moved to Belgium, for a Residency in Internal Medicine and Neurology at Liege University ; following the Belgian Board of Neurology (which he got with high marks), he moved to the National Hospital for Nervous Diseases, Queen Square, London, United Kingdom , for a fellowship in Clinical Neurophysi-ology, under Pr Willison ; Dr B Mesraoua had also further training in Epi-lepsy and Continuous EEG Monitoring for two years in the Neurophysiolo-gy department of Zurich ,Switzerland ,under late Pr Hans Gregor Wieser ,an internationally known clinical epileptologist .
Dr B.Mesraoua is currently Director of the Neurology Fellowship Pro-gram at the Neurology Section at HMC, Doha, Qatar; he is also Assistant Director of the Residency Program at Qatar Medical School.

Internationally, Dr Mesraoua is currently a member of the ILAE Publica-tion Council (2021-2025 term) with the aim of improving the quality of the publications targeting the journals Epilepsia, epilepsia open and epileptic disorders and also a member of the ILAE Task Force Innovation Con-gress with the aim of organizing and improving the quality of the next in-ternational epilepsy congresses.He was also an active and elected member of the Commission on Eastern Mediterranean Region (EMR ) , a region-al branch of the ILAE,(2017-2020);
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
