An 'aura' is the term that some people use to describe the warning they feel before they have a tonic clonic seizure. An epilepsy 'aura' is in fact a focal aware seizure.
Focal aware seizures (FAS) are sometimes called ‘warnings’ or ‘auras’ because, for some people, a FAS develops into another type of seizure. The FAS is therefore sometimes a warning that another seizure will happen (see focal to bilateral tonic-clonic seizures).
Some people may describe their auras as:
• a ‘rising’ feeling in the stomach or déjà vu (feeling like you’ve ‘been here before’);
• getting an unusual smell or taste;
• a sudden intense feeling of fear or joy;
• a strange feeling like a ‘wave’ going through the head;
• stiffness or twitching in part of the body, (such as an arm or hand);
• a feeling of numbness or tingling;
• a sensation that an arm or leg feels bigger or smaller than it actually is; or
• visual disturbances such as coloured or flashing lights or hallucinations (seeing something that isn’t actually there).
