Definition

A seizure is a sudden change in behavior. It is caused by sudden, abnormal, and excessive electrical activity in the brain. A neonatal seizure occurs in newborn babies.
Seizures may be severe or mild. They may cause physical changes like convulsions. It may affect only part of the body or the entire body. A short seizure itself does not cause serious health conditions. Prolonged seizures can lead to permanent damage. The damage is due to decreased oxygen and excessive brain cell activity.

Causes

There are a variety of causes of seizures in children, which include:
Sometimes seizures occur for unknown reasons.
 

Diagnosis

Your doctor will ask about your child‘s symptoms and medical history. A physical exam will be done. Tests may be done to look for the cause of the seizure.
Tests to look for infections may include the following:
  • Lumbar puncture —removal of a small amount of cerebrospinal fluid for testing to look for infection in brain or spinal cord
  • Blood tests—to look for infections, low blood sugar, abnormal electrolytes, or poison
Tests to look for abnormalities in brain may include:
  • CT scan of the head —a type of x-ray that uses a computer to make pictures of structures inside the head
  • MRI scan of the head —a test that uses magnetic energy to make pictures of structures inside the head
  • Electroencephalogram (EEG) —a test that records the brain’s activity by measuring electrical currents through the brain
 

Treatment

Treatment for the seizures depends on the cause of the seizures. Some seizures will not require treatment. If the seizure is caused by an underlying condition your child's doctor will create a plan to treat that condition. Resolving the underlying condition will likely stop the seizures.
Talk with your doctor about the best treatment plan for your child. You may also be referred to a pediatric neurologist.

Medications

Anticonvulsant medication can help to prevent seizures. The medication that is used will depend on the type of seizure. These medications do have some side effects. As a result, they are often only used for severe or frequent seizures.
Medications are not usually prescribed for febrile seizures . These seizures are associated with a rapid increase in temperature due to a fever. Children will outgrow these seizures by about 5 years of age. They are rarely associated with long term problems so anticonvulsant medication is rarely recommended.

Surgery

Some severe seizures may be treated with brain surgery. This may occur in some children with epilepsy. During this type of surgery certain nerve fibers may be separate or a section of the brain may be removed. This surgery may help to reduce or eliminate seizures. Surgery is not done very often.
If your newborn is diagnosed with neonatal seizures, follow your doctor's instructions .
If your newborn is diagnosed with neonatal seizures, follow your doctor's instructions .
