The Role of Electroencephalography in Children with Acute Altered Mental Status of Unknown Etiology: A Prospective Study.

Introduction:  Acute altered mental status (AAMS) is often a challenge for clinicians, since the underlying etiologies cannot always easily be inferred based on the patient's clinical presentation, medical history, or early examinations. The aim of this study is to evaluate the role of electroencephalogram (EEG) as a diagnostic tool in AAMS of unknown etiology in children.

Materials And Methods:  We conducted a prospective study involving EEG assessments on children presenting with AAMS between May 2017 and October 2019.
