Which medication is expected to increase beta frequency activity in EEG readings?

Benzodiazepines like Xanax, particularly, are known to enhance beta frequency activity in EEG readings. Beta waves, which range from 13 to 30 Hz, are associated with alertness, concentration, and readiness. These medications can heighten wakefulness and cognitive functioning, thus increasing the amplitude of beta activity in the EEG.

Ativan (lorazepam) and Diazepam (valium), while also part of the benzodiazepine class, may exhibit varying effects on EEG, often resulting in sedation which can hamper beta wave activity. Phenobarbital, an anticonvulsant medication, is generally associated with increasing slower wave activities on EEG and may suppress beta frequency. Therefore, Xanax is the medication most closely linked with enhancing beta frequency activity during EEG monitoring.
