A youngster may have a wide range of symptoms depending on the type of seizure. Some seizures are easily recognized and have well-known symptoms such as shaking and loss of consciousness. Others are less noticeable and may have no visible symptoms at all. Any type of seizure can be fatal if it goes on long enough. Children can have seizures for many different reasons. Some children will have several episodes a day while others will only have one or two seizures in years. There are several factors that determine how serious these seizures may be. A child's age, how often they occur, what type of seizure they have and their response to treatment are all factors in determining how much damage the seizure may do. In some cases, the brain may be damaged even after a single seizure episode. Children who have recurrent seizures are likely to have other problems too. They are more likely to experience developmental delays, learning difficulties and behavioral problems. These problems are often due to the fact that young brains are still developing so any interference with normal brain function or activity is likely to have negative effects. Some types of seizure can lead to severe injury or death if they go on long enough. This is particularly true if the child loses consciousness during the seizure. In this case, the child needs immediate medical attention regardless of how many seizures they have had before today.
