Let’s start with some background:
💡 #EEG = electroencephalogram
💡 What an EEG does: records electrical activity in the 🧠

You might then 🤔: how does the 🧠 create ⚡️?
A bit of neuroscience: 🧠 cells called neurons generate ⚡️ through the flow of charged ions (sodium & potassium) across their membranes
An EEG on the scalp can't detect the ⚡️ of a single neuron, but can when neurons are in sync

Starting today, I will be incorporating child neurology cases through a collaborative effort with @TheNotoriousEEG and @cookchildrens. 👏

Emory/Cook EEG Case of the Day #20 (Peds Case #1):
Hx: 4yo F with sensorineural hearing loss presents with epilepsia partialis continua in the setting of a viral respiratory infection. Her labs showed mildly elevated LFTs.
Questions:
1) What pattern is present?
2) What is the suspected diagnosis? Which AED should be avoided?

As we read #EEG studies, we look for specific brainwave patterns and rarely stop to think about the molecular/cellular events that are taking place to yield each component of the recording. This thread is a reminder of that! #MedEd #twEEGtorial #tweetorial #Neurology

My favorite example is the focal epileptiform discharge. We’re very good at detecting focal spike/sharp waves on routine surface EEG studies. So good that we can train machines to teach themselves to recognize them fairly accurately! E.g. jamanetwork.com/journals/jaman…

But what is a spike/sharp wave saying about underlying brain events? Let me take you from scalp to cell, step by step. Here’s a surface recording in longitudinal bipolar with LFF = 1 Hz, HFF = 70 Hz, S = 7 uV/mm, t = 30 mm/sec.
