Someone who has Epilepsy has it all the time. What you really mean is how often do they have seizures. There is no single answer for that, as different people have them at different times. Some people could go years without having a seizure. Others might only go a few hours without having one. It depends on the type of epilepsy, the severity of the epilepsy and the triggers for individual people. A trigger is something that may cause a person to have a seizure. If they avoid their personal triggers, then they could go without seizures for a long time.
One form of epilepsy, which only affects about 3% to 5% of people with epilepsy is photosensitive epilepsy. This is the form when people have their seizures triggered by light patterns. Most people associate this with flashing lights, but there can be other causes. If someone has photosensitive epilepsy and regularly expose themselves to situations where they encounter flashing lights, then they will have more seizures. If they keep away from those situations, then they could go without them for a very long time.
Other people have no problems with flashing lights, but will get seizures due to things like stress. If they avoid stressful situations, then they won't have seizures very often. So someone will have epilepsy all the time, but will only have seizures occasionally, if they look after themselves and avoid their triggers as much as possible.
Edit: *** Depends on their triggers like me for example i have seizures and one of my triggers is stress that's hard to avoid but I meditate, listen to music, hang with friends, shop, get nails done, fix my hair, go out on a date, Girls Night Only, and text. These are what I do other people could do something else.***
The immediate complication of epilepsy is simply the risk of getting a seizure :-)
The probability of getting 2 pairs in a poker hand is higher than the probability of getting 3 of a kind.
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
There is no probability. Sorry.
The probability of getting the queen of hearts is 1 in 52, or about 0.01923. The probability of getting any queen is 4 in 52, or about 0.07692. The probability of getting any heart is 13 in 52, or exactly 0.25.
The probability is likely to be 1.
It isn't passed from one dog who has epilepsy to another healthy dog that doesn't have epilepsy by contact or any other way except genetically. Epilepsy can be passed on genetically. Such as the Sire or Dam of the pups can have epilepsy & the pups' odds of getting epilepsy are much higher.
The probability of tossing a coin and getting heads is 0.5
The probability of flipping a quarter and getting heads is 1 in 2. the probability of rolling a die and getting 6 is 1 in 6.
There are many reasons and causes of epilepsy, so it is not really possible to say what can be done to avoid it. It isn't like an infectious disease that you can get vaccinated against. Only about 1 in every 200 people have some form of epilepsy. Something like a head injury can result in epilepsy, so you could say that trying to avoid getting any sort of a serious head injury in your lifetime is one way or trying to avoid getting epilepsy.
The probability of not getting a club is the same as the probability of getting one of the other suits. There are (52-13)=39 such possibilities out of 52. Hence the probability is 39/52=3/4.
If someone gets some damage to their brain, this can result in someone getting epilepsy. So if someone had a aneurysm in their brain and some damage was done, it is possible that epilepsy could develop epilepsy, but it is not certain that it would happen.
