What are Febrile convulsions? – Epilepsy learner Video 4

Febrile Seizures in Children

• Febrile seizures are the most common type of seizures observed in children between 6 months and 5 years of age. 
• They are not considered epilepsy, as they occur in association with fever rather than chronic neurological conditions.
• The likelihood of febrile convulsions is often influenced by genetic factors, meaning a family history can increase risk.
• According to Dr. Nikit Shah, febrile seizures affect as many as 20 out of every 100 children, even when epilepsy is not the underlying factor 

Possible Causes of Febrile Seizures

• Genetic Correlation:
  Children with a family history of febrile seizures are more likely to experience them, suggesting a strong genetic influence.
• Rapid Rise in Temperature:
  A sudden spike in fever—often reaching 102°F (38.9°C) or higher—can trigger convulsions.
  • It is the speed of the temperature increase, rather than the absolute level, that often matters.
  • A gradual rise in fever is less likely to cause seizures compared to a rapid spike.
• Not Every Fever Leads to Seizures:
  While febrile seizures are linked to fever, not all fevers result in convulsions. Many children with high temperatures never experience seizures.

Management of Febrile Seizures

• Fever Control:
  • Aggressive management of fever (using antipyretics or cooling measures) may not completely prevent febrile seizures.
  • However, lowering the temperature can help comfort the child and reduce distress.
• Medication Use:
  • Anti-convulsants may be prescribed in certain cases, especially if seizures are prolonged or recurrent.
  • Routine use of anti-epileptic or anti-seizure drugs is not recommended for febrile seizures, since these episodes are generally self-limiting.

In most cases, no specific treatment is required beyond supportive care. The focus is on reassurance and monitoring, as febrile seizures typically resolve on their own without long-term consequences.

Investigation of Febrile Seizures

• Typical Cases:
  • In most children, no investigation is necessary.
  • Diagnosis is usually based on parental history, including details such as:
  • Number of seizures
  • Duration of each episode
• Exceptions Requiring Further Evaluation:

Investigations may be considered when:

• The child experiences prolonged or recurrent febrile seizures.
• Seizures occur in a pattern different from the usual febrile seizures seen in children.

• Possible Tests:
  In such cases, doctors may recommend:

• Electroencephalogram (EEG): To assess brain activity.
• Magnetic Resonance Imaging (MRI): To rule out structural or neurological abnormalities.
