It can be. Many people can have a seizure and exhibit no outward signs other than standing still looking a bit confused. But the type of seizure seen on TV certainly does happen.
There are many forms of seizure and a person having one can behave in different ways. It is usually very clear that they are not drunk but are having some other problem, namely a seizure. There are many ways of knowing that someone is drunk, and it would be very obvious that they will have been taking alcohol. A seizure is not like that.
To control anything during a seizure is not really possible, so you could not consciously do it. You could wear some protection in your mouth, but that isn't very practical and you don't know when a seizure will happen. It can also be dangerous having something in your mouth when you have a seizure as you could do other damage, like to your teeth. So there is not very much that can be done to stop yourself biting your tongue when you have a seizure.
You've done something wrong to it.
The dog is possibly having a seizure. You should take it to your veterinarian as soon as possible to be checked.
Because you are tickling him and he can't stand it.
Not really no, you can only determine it from patient history, first person observation or EEG changes during a seizure.
they really look bad and i mean BAD..
When you have a seizure, your brain is malfunctioning so you are not conscious of what is going on. It is like the fact that you do not remember being asleep. You can remember dreams when you sleep and you may remember having a dream when you have a seizure. Whether you do or not, you will usually know that you have had a seizure, in the same way that you will usually know that you have been asleep.
sounds like it may be having a seizure. Yes this would be bad see a vet.
No, she's just awful. Looks like she's having a seizure while singing too.
Once a seizure is finished, a person will soon start to get back to normal. Within hours or even minutes, they will be fine. If they had a very bad seizure, they may feel unwell for some time, maybe still feeling a little unwell the day after, like still having a bit of a headache. They may not have another seizure for a very long time. So there may be nothing particular that will happen days after a seizure. Everything will be back to normal long before that.
It sounds like he is having a seizure, or lack of oxygen to the brain. He needs to get to a vet!
