Hemispherotomy Helps Children with Drug-Resistant Epilepsy in Panama
A study was conducted to evaluate the outcomes of a surgical procedure called hemispherotomy in 23 children with drug-resistant epilepsy (DRE) in Panama.
Imaging & EEG

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.

Understanding Focal Delta Slowing in Epilepsy
Researchers studied the patterns of brain activity in people with focal epilepsy, focusing on a specific type of brain wave called “focal delta slowing.” This type of slowing appears on electroencephalograms (EEGs), which are tests that measure electrical activity in…
