Investigations for Epileptic Seizures

  • Thalia Valeta


The diagnosis of epilepsy is mainly based on the clinical information. However, a number of investigations (laboratory procedures) may be requested in order to make certain that the diagnosis is correct. The main laboratory procedures for a patient with possible or definite epileptic seizures are the electroencephalogram (EEG) and the brain imaging (brain MRI and brain CT scan). A physician may also request blood and urine test, ECG (electrocardiograph) or even more specific investigations such as metabolic or toxicology screening and molecular genetic testing. These depend on the particular clinical problem and individual patient.
