What is the initial investigation for seizures?

The initial investigation for seizures is often a clinical assessment followed by an EEG (Electroencephalography), which is not selected in this case. EEG is crucial for documenting the electrical activity in the brain, helping in the diagnosis of seizure types and potential underlying issues.

While a CT scan and MRI can be valuable for visualizing structural abnormalities in the brain, these imaging modalities are typically utilized if there are indications of complications or when other structural issues are suspected. Transcranial ultrasound is not the conventional first-line investigation in the setting of seizures; it may occasionally be used in specific clinical scenarios, particularly in evaluating neonatal seizures, but it does not replace EEG in the initial evaluation of seizures in a broader sense.

EEG serves as a cornerstone for seizure assessment, enabling healthcare providers to categorize the seizure type and determine appropriate management strategies.
