Abstract:

Vasovagal syncope precipitating an epileptic seizure has only rarely been described. A patient with known intractable complex partial seizures being evaluated for a left anterior temporal lobectomy experienced a typical seizure with mesial temporal onset precipitated by an observed vasovagal episode. This is the first report of a partial epileptic seizure precipitated by vasovagal syncope and the first example of an epileptic seizure induced by syncope in an adult. Video and intracranial depth electrode and subdural grid recordings documented the event.

Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
