First Seizure or Fit Attack — What Happens Next?
A first seizure is a frightening experience for both the patient and family. A thorough evaluation determines the risk of recurrence — and whether medication is needed.
Experiencing a first seizure — a sudden, uncontrolled electrical disturbance in the brain — is deeply alarming. The critical questions after a first seizure are: Was this a provoked seizure (caused by something correctable — fever, low blood sugar, alcohol withdrawal, medication) or an unprovoked seizure (idiopathic or structural brain problem)? And what is the risk of another seizure? These questions are answered through a structured evaluation including EEG, blood tests, and brain imaging.
Seek Emergency Care Immediately If You Have:
- 1Seizure lasting more than 5 minutes — call emergency services immediately
- 2Cluster of seizures without full recovery between them
- 3Seizure in pregnancy
- 4Seizure with fever and neck stiffness (possible meningitis)
- 5First seizure in a patient over 60 (higher risk of structural cause)
Possible Causes of This Symptom
Febrile Seizure (Children)
The most common seizure type in children aged 6 months to 5 years — triggered by rapid temperature rise. Usually benign and brief. Neurological assessment recommended after any febrile seizure.
Provoked Seizures (Adult)
First seizures in adults triggered by very low blood sugar, very low sodium, alcohol withdrawal, fever (encephalitis), or certain medications. Treating the underlying trigger is the primary management.
Unprovoked First Seizure
Seizure with no identifiable acute cause. Risk of recurrence is approximately 40–50% after one unprovoked seizure — rising to 80% after a second. Decision about medication is made with the patient after full evaluation.
Structural Brain Abnormality
A seizure caused by a prior stroke, brain tumour, cortical dysplasia, or other structural lesion. Brain MRI is essential to identify a structural cause.
Generalised Epilepsy Syndromes
Some first seizures represent the initial presentation of a specific epilepsy syndrome — juvenile myoclonic epilepsy, childhood absence epilepsy — which have specific treatment implications.
How We Diagnose the Cause
EEG (Electroencephalogram)
In-house EEG records brain electrical activity, helps classify seizure type, identifies specific epilepsy syndromes, and quantifies epileptiform activity.
Blood Tests
Blood glucose, sodium, calcium, magnesium, renal function, and liver function — ruling out metabolic causes and providing a baseline before medication.
MRI Brain
Recommended for most adult first seizures — especially when focal onset is suggested by the clinical description or EEG. Identifies structural causes (tumour, stroke, dysplasia).
