Generalized tonic-clonic seizures of epilepsy

Generalized tonic-clonic seizures (secondary generalization) of epilepsy: simple partial seizures can develop into complex partial seizures, and simple or complex partial seizures can generalize to generalized tonic-clonic seizures. Remember that symptoms are a precursor to a focal attack. Sudden loss of consciousness without a clear description of aura symptoms is highly suggestive of seizures. Local sensory or motor symptoms, such as involuntary twitching of one limb, abnormal facial sensation on one side, and forced head turning, suggest that the epileptic seizures originated from the contralateral frontal parietal cortex. Fear, olfactory or taste hallucinations, visceral sensations, or seemingly acquaintances often result from temporal lobe seizures.
