While prolonged EEG is a valuable tool, other diagnostic methods can complement or sometimes substitute it, such as: - Cranial ultrasound: Useful for detecting structural abnormalities. - Magnetic Resonance Imaging (MRI): Provides detailed images of the brain’s structure. - Near-infrared spectroscopy (NIRS): Monitors brain oxygenation and hemodynamics. - Amplitude-integrated EEG (aEEG): A simplified form of EEG that can be easier to use in some settings.
