Diagnostic test
EEG testing.
EEG testing measures electrical activity in the brain to help diagnose neurological conditions. At Thema Brain Health, EEG is performed as part of a comprehensive neurological evaluation.
What is an EEG test?
An EEG records brain electrical signals using small sensors placed on the scalp. The test does not send electricity into the brain — it simply records activity. EEG helps neurologists understand how the brain is functioning and identify abnormal patterns.
How is EEG testing performed?
EEG testing is painless and non-invasive. Sensors are placed on the scalp, and brain activity is recorded while resting or performing simple tasks. The test usually takes a short amount of time and does not require recovery afterward.
When is EEG testing recommended?
- Memory loss or impaired cognition.
- Seizure evaluation.
- Episodes of altered awareness.
- Unexplained loss of consciousness.
- Certain sleep-related neurological concerns.
EEG testing is ordered only when medically appropriate.
What do EEG results show?
EEG results help identify abnormal electrical activity in the brain. Results support diagnosis but are not used alone — a neurologist interprets findings in combination with symptoms and medical history.
Frequently asked questions
- Is EEG safe?
- Yes. EEG testing is very safe and painless.
- Can EEG diagnose epilepsy alone?
- EEG supports the diagnosis of epilepsy but is not used by itself — clinical context and history are essential.
- How should I prepare?
- Preparation instructions vary and will be provided in advance if needed.
- How many visits does EEG testing take?
- Most tests are completed in one visit.
