Partial Seizures
A partial seizure with secondary generalization may start in one area of the brain then spread to the entire brain. The spread through the brain may be slow and include an aura, or it may spread quickly and quickly become a generalized convulsion. Generalized onset seizures can include convulsions, jerks, momentary loss of awareness and loss of muscle tone.
