Often it is only the intensity and suddenness of these feelings that differentiates between someone having a usual d ja vu experience, for example, and someone having a simple partial seizure. If a seizure originates in the frontal lobe, the person will experience a totally different set of symptoms. Because this area of the brain deals primarily with movement, the symptoms are sometimes called motor seizures . The person may feel their head drawn to one side. Sometimes their arm or hand becomes stiff and is drawn upwards.
Some people then experience some jerking movements in that limb.
If this symptom spreads to other parts of the body it may be what is called a Jacksonian seizure, a very rare type of seizure named after British neurologist, Hughlings Jackson. Sometimes this can spread to the rest of the brain and become a tonic-clonic seizure. If a person s head is drawn to the left or it is the left hand or arm affected by the seizure, this means that the epileptic activity is occurring in the right frontal lobe and vice versa. Because this lobe also controls part of our speech, some people experience speech arrest , resulting in an inability to talk or not being able to be understood. After this type of seizure, which again is usually only brief, the person can experience a short period of weakness.
