In focal epilepsy, spikes are restricted to one hemisphere of the brain.
Yes, it is quite common for those who have Partial Epilepsy for EEG's and MRI's to be clear as the section is not thin enough or only a small part of the brain is affected.
It's actually pretty easy to manipulate an EEG to not show epilepsy. Drinking caffeine makes it harder to find epilepsy because it speeds up the brain's activity and makes it harder to pick up on any abnormal patterns. Taking Lamotrigin and Levicritam can also make it harder to find epilepsy because they both interfere with the electrical signals in the brain.
An EEG is an electroencephalogram which is a device that measures brain activity. If there any problems in the brain they can be seen on an EEG. The brain produces electrical impulses and there are different patterns of impulses. It is this different patterns that are measured with and EEG that can show doctors what might be wrong.
One hopes you might be using your brain when having sex ......... although if someone could have a flat eeg during sex, I'm impressed, that's control !
Yes, brain tumours can show up very clearly on CT scans especially if the patient is injected with an X-ray dye.
TLE, as a whole, constitutes a common type of epilepsy. The exact incidence is not clear but it is suspected to make up a significant proportion of medication-resistant epilepsy.
Not necessarily. It will depend on the type and cause of epilepsy. Some children get epilepsy which stops when they grow up. Some people get epilepsy as a result of a head injury. If the head injury heals their seizures may stop. Some people will have their epilepsy for life. They could have it for all of their life, or get it at some point and then have it for the rest of their life. Epilepsy can be controlled by medication, so some people get their epilepsy under control and if they stick to looking after themselves, they will not have seizures although technically they still have epilepsy. Each case is different and it has to be monitored by the person and their doctor.
Not really. There are many forms of epilepsy so you can have the same kinds of seizures when you are an adult as when you are a child. Issues like age and gender don't really make a difference. Some children stop having seizures when they grow up and other people will have epilepsy throughout their life and other people may only get epilepsy when they are adults.
If that happens regularly then it could well be epilepsy. The only way to really know is to go to see a doctor.
The leads will placed on your head, or skull.
Yes, but it doesn't just float there in thin air. You need something there to make the image show up, such as smoke, tissue paper, fog, steam, ground (frosted) glass, etc. If you don't have any of those, you can take a short-focus eyepiece and look at the focal point with it. In the eyepiece, you'll see the image at the focal point. (It won't look like an image. It'll look like the object.)
Yes, all works of art have a focal point. It is up to the viewer to determine where the focal point is located at. Although, the artist generally has an idea to where the focal point is located when creating their piece.
