Patient discussion about Seizure

Q. SEIZURE what are the causes of a person having a seizure?

A. thank you for the link i will order it--mrfoot56

Q. is there ususlly strange feelings associated with seizures? I am 30 years and i have just been diagnosed with absence seizures. There are some strange feeing that i cannot identify as fear or fustration or anxiety or depression or sadness associated with this new illness. Is it normal? Can it be identified? How can i get rid of all the conditions associated with this disease as well as the absence seizure itself?

A. any affect that the seizures have on your personality (mood change and such)can go away if the condition will be treated. treating epilepsy seizures require first of all a good neurologist. he will help you the treatment that will suite you the most. there are more then one line of treatments in epilepsy.

Q. what are the chances for a one time epileptic seizure? I had an epileptic seizure a few years ago and after all the tests it appeared to be a one time seizure. I know having one indicates my tendency for this kind of seizures so should I be afraid now to do things that might bring it up again- like alcohol, drugs, being exposed to flashing lights or having lack of sleep? what are the chances of it to come back after 5 years? any help will be very appreciated....thanks!

A. After 5 years with no recurrence of seizures after a one time episode, tha chances of having another one are low, almost exact to the general population. I would not advise you to start heavily drinking alcohol and doing drugs, because these things can certainly have an effect, however you need not be afraid.
