[5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
A simple febrile seizure is generalized, occurs singularly, and lasts less than 15 minutes. [19] A complex febrile seizure can be focused in an area of the body, occur more than once, and lasts for more than 15 minutes.

Tonic-clonic seizures, also known as Grand Mal seizures, present with continuous stiffening of the body for 10–20 seconds followed by rhythmic jerking. [8] [13] It may be accompanied by an increase in blood pressure, increase in heart rate, urinary incontinence. [8] [5] The person may turn blue if breathing is impaired.
[1] [7] The symptoms can be managed by initially introducing a seizure suppressing medication as the first stage of the treatment, which optimally works only for that stage because any delay will reduce the efficacy of those medications. Convulsive status epilepticus commonly affects the elderly and young children, with a mortality rate of up ...

Common signs of a seizure include: [1] Movement: Jerking movements of arms and legs, stiffening of the body, rhythmic head nodding, rapid eye blink and staring, sudden falling (typically as a result of loss of consciousness)

Generalized seizures can take the form of myoclonic jerks, absences, or generalized tonic-clonic seizures. [2] Myoclonic jerks are the most common generalized seizures seen among reflex seizures and can be located in the limbs, trunk, or in specific regions of the body (e.g., in the muscles of the jaw or the eyelids).
