EEG remains the most widely used investigation when epilepsy is suspected, but how and when does one use EEG in the diagnosis of epilepsy?
When not to use EEG to diagnose epilepsy
Epilepsy diagnosis is not always straightforward. Diagnosis depends on precise history taking, general medical and neurological examination, and prudent use of diagnostic tools. Depending on symptoms and examination a physician may order a variety of investigations including EEG, QEEG, ECG (to rule out heart problems like syncope), imaging techniques (including MRI, CT scan, and PET scan), lumbar puncture, prolactin study, blood tests and neuropsychological screening.
