EEG question

[Daisyduke]

Newly diagnosed and EEG results--

"Paroxysmal generalized sharp theta discharges are noted throughout the recording. High amplitude beta waves are noted throughout the record"

Can theta and beta waves be affected by medications such as benzodiazepine?

 

[Nakamova]

Very generally speaking, benzodiazepines tend to increase beta waves, and may slow theta waves. But it's best to consult with your neuro, since there are a lot of factors involved in evaluating an EEG -- not just the particular meds that you might be on, but also the dosage and blood serum levels, and whether you've been on them short-term or long-term. Additional factors for diagnosing epilepsy include the time of day, whether you are drowsy or alert, whether you've had a recent seizure, etc. Spikes are evaluated based on their rhythm and in contrast to any background slowing. Also important is where in the brain the activity occurs and whether it is symmetric or asymmetric.

Beta waves are associated with alertness and focus if you are awake, and with the REM phase if you're asleep. (They can also show up when you have taken high doses of benzodiazepines.) Very high-amplitude beta waves are sometimes a sign of anxiety or tension.

Theta waves are associated with daydreaming/drowsiness and the transitional period between waking and sleeping. This phase can be one of the more likely phases for seizures to occur. Sharp paroxysmal bursts of theta would tend to indicate epilepsy, however the best person to interpret the EEG would be your neuro.
