In what way can medication affect EEG interpretation?

Medication can significantly affect EEG interpretation primarily by altering neuronal activity. Different drugs can enhance or suppress the electrical activity of neurons, which in turn influences the EEG patterns observed during the recording. For instance, anticonvulsants can stabilize neuronal excitability, leading to a reduction in seizure activity, while sedatives may produce a general slowing of brain rhythms.

Understanding this interaction is crucial for accurate EEG interpretation, as the effects of medication must be considered when analyzing the resulting brain wave patterns. Changes in neuronal activity can manifest as variations in amplitude, frequency, and rhythm, necessitating a comprehensive approach to assess the underlying brain function. In clinical settings, it is important to correlate EEG findings with the patient's medication history to provide context for any observed changes.
