1. What Exactly Is an EEG?
An EEG is a non‑invasive test that records the brain’s electrical activity through tiny sensors (electrodes) placed on the scalp. Think of it as a heart EKG for your brain—capturing real‑time communication between billions of neurons.
Fast facts
Zero pain, zero radiation
Captures activity as little as one‑millionth of a volt
Standard study lasts 20–40 minutes; extended video‑EEG can run 24 hours+ if needed
2. Conditions We Detect with EEG
Seizures & Epilepsy: Identifies interictal spikes, seizure onset zones, and guides medication decisions.
Unexplained Fainting (TLOC): Differentiates epileptic seizures from syncope or psychogenic events.
Memory Fog & Cognitive Spells: Detects subclinical seizure activity that routine imaging may miss.
Sleep Disorders: Evaluates sleep stages; screens for REM behavior disorder and narcolepsy.
Quick Note: A normal routine EEG does not rule out epilepsy—Charis Neurology offers extended video‑EEG for elusive cases.
