Epilepsy & Seizures
Dr. Mit Ankur Raval
A seizure is a transient event caused by abnormal brain electrical activity. Epilepsy is a predisposition to recurrent unprovoked seizures.
Understand the condition
What patients should know.
Possible features
Loss of awareness, convulsive movements, staring/behavioural arrest or episodic confusion may occur.
Assessment
A detailed history, eyewitness/video account, examination and appropriate tests such as ECG, EEG or imaging help determine the diagnosis. NICE recommends urgent specialist assessment after a first suspected seizure.
Treatment
Treatment depends on seizure type, syndrome, recurrence risk and patient circumstances.
Emergency
A prolonged convulsive seizure or repeated seizures without recovery is an emergency.
Patient questions
Frequently asked questions
Does a normal EEG exclude epilepsy?
No. EEG supports diagnosis in the appropriate context but is not used to exclude epilepsy when normal.
What should I bring?
A witness account or safe video of the event can be very helpful.
