While many variations exist, an increase in beta wave activity and a mild increase in theta waves are the most common electroencephalogram (EEG) alterations associated with medication [1.2.2, 1.10.4]. Answering 'What is the most common drug effect on EEG?' involves understanding how different drug classes interact with the brain's electrical signals.
