anybody ever had a tonic clonic seizure and then had clear results (ct/eeg) worried what caused it?

Answer 1

For children who have had a single tonic-clonic seizure, the risk that they will have more seizures depends on many factors. Some children will outgrow their epilepsy. Epilepsy
A disorder characterized by transient but recurrent disturbances of brain function that may or may not be associated with impairment or loss of consciousness and abnormal movements or behavior.Close Often, tonic-clonic seizures can be controlled by seizure medicines. Many patients who are seizure-free for a year or two while taking seizure medicine will stay seizure-free if the medicine is gradually stopped. The risk that an individual will have more seizures depends on factors such as whether his or her EEG shows any epilepsy waves, or whether the doctor finds any abnormalities on a neurological exam. Among children with no epilepsy waves and a normal exam, about 70% of those who have had tonic-clonic seizures will stay seizure-free without medication. The comparable number is less than 30% for children with epilepsy waves and an abnormal exam. All these figures are more favorable than those for partial seizures.
Often, the cause of a seizure is unknown. Some of the known causes of seizures include:

Metabolic disturbances. Diseases of the kidney or liver can cause chemical disturbances in your body, as can very low levels of sodium, calcium or magnesium.

Previous brain trauma. Traumatic head injuries, such as those sustained in automobile accidents or serious sports injuries, can cause seizures.

Vascular system problems. Blood vessel disorders, such as arteriovenous malformation of the brain — in which an abnormal connection exists between arteries and veins, and strokes are common causes of seizures in older adults.

Toxic substances. Using drugs or other chemicals or withdrawing from addicting substances, especially alcohol, can affect your brain's electrical activity and your nervous system.

Infection. An inflammation of your brain, such as that caused by meningitis or encephalitis, may trigger a seizure.

Birth defects. Congenital malformations in the brain can be responsible for seizures in infants and young children.

Brain tumor. Although a brain tumor is an uncommon cause, a seizure may be an indication of a brain tumor.

Answer 2

I have seizures, but not the one you have listed. My neurologist found my EEG off and that's how I was diagnosed with epilepsy. However, when I first was diagnosed and everything was explained to me I was told you can have your EEG come back normal even if you have epilepsy. This wasn't the case for me, but it could be for you.

Answer 3

I had one and noone could ever tell me what caused it, I was using paxil at the tiem and a pharmicist told me that a very small percentage of people using paxil will have seizures.
