The Role of EEG

An EEG, or electroencephalogram, is a key test in diagnosing seizures. It measures electrical activity in the brain and can identify abnormal patterns associated with seizures. This test is often done after a first seizure to help determine the risk of recurrence.

Neuroimaging: CT and MRI

CT scans and MRIs are used to look at the brain's structure. These imaging tests help doctors spot any physical abnormalities, like tumors or scar tissue, which might be causing seizures. MRIs are preferred due to their detailed images.
The process of diagnosing seizures involves EEG tests to measure brain activity and neuroimaging techniques like CT and MRI scans to identify brain abnormalities.

Blood Tests and More

Blood tests can detect underlying issues that might trigger seizures, such as electrolyte imbalances or infections. Additionally, tests like ECGs can rule out heart-related causes of seizures, ensuring a thorough evaluation.

FAQs

What is an EEG?

It's a test that measures brain's electrical activity.

Why are MRIs preferred over CT scans?

MRIs provide more detailed images of the brain.

Can blood tests help diagnose seizures?

Yes, they can detect triggers like electrolyte imbalances.

Is an ECG necessary?

Yes, to rule out cardiac causes of seizures.

The Bottom Line

A combination of tests provides a clearer picture for diagnosing and managing seizures.
