EPILEPSY

Epileptic seizures can have very diverse manifestations. They can occur without screaming or loss of consciousness, without stiffening, tongue biting, and collapsing, without turning blue or having convulsions. They can be so harmless that neither the person affected realises it nor the non-expert notices anything when they directly observe a seizure.

The only sign of an epileptic attack can be inattentiveness for five to ten seconds or a brief twitching of one arm.
