Seizure

You may find this interesting:

Temporal lobe epilepsy

This type of seizure arises from abnormal electrical activity in the temporal lobe on one or both sides of the brain. Half the patients with this disorder have a partial seizure meaning the seizure does not continue to shaking of the arms and legs (tonic clonic seizure). These seizures have a characteristic pattern, see the symptom section. The seizure occurs because of scarring or other damage to the temporal lobe of the brain. Sometimes the reason for the scarring is unknown. Other causes include: multiple sclerosis, trauma, infection, tumor, and stroke.

Symptoms:
An aura consisting of a warning sensation, strange smell or taste, or feeling of deja vu may occur before the seizure. The aura is followed by lip smacking, loss of sense of surroundings, blank starring, swallowing, or strange finger movements. In half the patients the above symptoms will be followed by shaking of the arms and legs and loss of consciousness. Most patients will have no memory of the seizure.

Treatment:
Therapy is directed at preventing the patient from harming themselves during a seizure, stopping the seizure, and preventing future seizures. Treatment may include: close monitoring of vital signs, padding on the gurney, supplemental oxygen, anti-nausea medications, benzodiazepines (diazepam Valium, lorazepam Ativan), and or anti-seizure medications. For persistent seizures or if the seizures are from a brain tumor surgery may be necessary.
Other tests are done to help confirm the diagnosis.
Other Specific Tests:
EEG, lumbar puncture
