Electroencephalogram (EEG): Prolonged/Routine:

Is an evaluation of the brain electrical activity. EEG can be performed in multiple approaches and can be prolonged (24 hours), or Routine (20 minutes). EEG has many application areas such as:

• Inpatient (regular ward or ICU)
• Outpatient
• Neonatal and pediatric ICU

The prolonged EEG allows the patient to proceed with normal day-to-day activities and brings a prolonged recording of electrical impulses to the brain which assists in a comprehensive view of brain cells’ activities. The 24 hours EEG can be done inpatient or ambulatory as an outpatient. It can also diagnose nonconvulsive seizures in comatose patients which can alter the management plan. Research stated that up to 34% of comatose patients in the ICU have subclinical seizures.
