Predicting Recovery After Cardiac Arrest Using EEG Patterns
This study focuses on understanding how certain brain activity patterns, seen in electroencephalograms (EEGs), can help predict the recovery of people who survive cardiac arrest.
Imaging & EEG
This hub covers epilepsy EEG and MRI: how EEGs and brain imaging help doctors understand seizure patterns and possible causes. Clear explanations of common findings and what research suggests.

Imaging & EEG: What Families Usually Want to Know
- What an EEG can (and can’t) tell you
- Why EEGs can be “normal” even when seizures are real
- When MRI/other imaging matters (and what doctors look for)
- What “spikes,” “slowing,” and “epileptiform activity” mean
Common EEG & Imaging Terms in Plain English
- EEG: Measures electrical activity from the scalp (not a brain “scan”)
- Epileptiform discharges: Patterns that suggest seizure risk
- Ictal: Refers to during a seizure
- Interictal: Refers to between seizures
- Focal vs. Generalized: Pertaining to one specific spot on or network on one side of the brain vs. both sides/networks
- MRI Lesion: A structural change that might be related (not always)
Imaging & EEG FAQ
Can you have epilepsy with a normal EEG?
Yes. EEGs are a snapshot. Some people need repeat EEGs, sleep-deprived EEGs, or long-term monitoring.
Does an abnormal EEG mean someone will definitely have seizures?
Not always. It raises suspicion and risk, but diagnosis still depends on the full story.
Why do doctors order an MRI?
To look for structural causes like scars, malformations, tumors, and stroke-related changes, which can guide treatment.
What is video EEG monitoring?
An inpatient or extended study that records EEG and video together to match symptoms to brain activity.
