Final answer:
Febrile seizures have a genetic component and do not usually lead to long-term complications or necessarily indicate a child will develop epilepsy later on.
Step-by-step explanation:
The true statement about febrile seizures is that there is a genetic link to febrile seizures. Febrile seizures are convulsions that can occur in young children with high fevers, typically between the ages of 6 months and 5 years. While febrile seizures are associated with fevers, which can be caused by both viral and bacterial infections, they are not exclusively linked to bacterial infections. It is also not accurate to say that a febrile seizure usually indicates that a child will develop epilepsy later on, although there may be a slightly increased risk compared to the general population.
Most children with febrile seizures do not go on to develop epilepsy. Regarding long-term complications, the vast majority of children who experience febrile seizures do not have long-term effects from them. However, a small percentage might have a higher chance of developing recurrent febrile seizures.
