Epilepsy is a chronic neurological disorder characterized by recurrent brief episodes of involuntary shaking (seizures) which may involve a part of the body (partial) or the entire body (general).


Individual at risk




ACCEPT if seizure-free for the previous 12 months WITHOUT medication.

DEFER if currently requiring medication


Guidance at CT/WORK-UP

ACCEPT if seizure-free for the past 12 months WITHOUT medication. Inform the anaesthetist at work-up of seizure history.

DEFER if currently requiring medication.


Justification for guidance

There is a potential increased risk for perioperative seizures due to the pre-existent condition or the proconvulsant effect of anaesthetic drugs, and also due to electrolyte changes experience during apheresis.

Anticonvulsant medications may cause abnormalities in blood counts, which may exacerbate those seen after PBSC.
