Introduction

Fever, also known as pyrexia, may sometimes lead to febrile seizures in children. Whether such seizures affect the brain depends on the underlying cause and duration of the seizure, and must be analyzed comprehensively. Because individual circumstances vary, it is impossible to make a general conclusion. If the seizure is a simple febrile seizure, it generally does not affect the child. However, if seizure symptoms persist, they may have some impact on the child's brain nerves.

Fever, also known as pyrexia, may sometimes lead to febrile seizures in children. Whether such seizures affect the brain depends on various factors including the underlying cause and duration of the seizure. Due to individual differences, it is not possible to make a general conclusion.

1. No impact: Because children's nervous systems and regulatory functions are not fully developed, they may lose control over the hypothalamus during fever, leading to seizures. If the seizure is a simple febrile seizure that resolves once the fever is under control, it is generally benign and does not affect the child’s brain nerves or intellectual development.

2. With impact: If the febrile seizure in a child is caused by brain diseases such as meningitis or encephalitis, and if the seizure symptoms persist, there could be some impact on the child's brain nerves, potentially affecting intellectual development.

If a child develops a fever, prompt management is recommended. If seizures occur frequently, medical attention should be sought immediately.

At what temperature will a child experience convulsions due to fever?

In general, there is no fixed temperature threshold at which a child will experience seizures during fever. Most often, seizures occur when body temperature rapidly rises above 38.5°C. However, some children may experience seizures even if their temperature does not reach 38.5°C. This primarily relates to individual physical condition and the speed at which body temperature rises. When a child has a fever, parents should closely monitor temperature changes and administer antipyretic medication promptly if the temperature exceeds 38.5°C.
