Benign Familial Infantile Seizures (BFIS) Description

Benign familial infantile seizures (BFIS) is a type of seizure disorder that affects young children, typically between 3 and 24 months of age [11]. This condition is characterized by sudden movements and changes in breathing, which can occur in clusters over a day or several days.

Key Features:

• Age range: Typically occurs between 3 and 24 months of age
• Seizure characteristics: Sudden movements and changes in breathing
• Cluster episodes: Seizures may occur in clusters over a day or several days

Important Notes:

• BFIS is a genetic epileptic syndrome that affects healthy infants [9][10]
• The condition is characterized by the occurrence of afebrile repeated seizures in healthy infants, between the third and eighth month of life [10]

Signs and Symptoms of Benign Familial Infantile Seizures

Benign familial infantile seizures, also known as BFIE, are characterized by afebrile repeated seizures in healthy infants. The symptoms of BFIE can vary from one child to another, but some common signs and symptoms include:

• Sudden stoppage of activity: Infants with BFIE may suddenly stop what they are doing, such as playing or feeding.
• Staring straight ahead or to one side: Children with BFIE may stare straight ahead or to one side, often without responding to their surroundings.
• Turning their eyes or head to one side: Infants with BFIE may turn their eyes or head to one side, which can be a sign of an impending seizure.
• Unusual movements: Some children with BFIE may exhibit unusual movements, such as jerking or twitching, especially on one side of the body.

These symptoms are often brief and may not be accompanied by any other signs of illness. In most cases, the child will return to normal after a few seconds or minutes. However, it's essential for parents and caregivers to recognize these signs and seek medical attention if they occur frequently or persist over time.

Diagnostic Tests for Benign Familial Infantile Seizures

Benign familial infantile epilepsy (BFIE) can be diagnosed through various tests, including:

• Electroencephalography (EEG): This is the first-line diagnostic testing for BFIE. EEG helps to characterize the interictal background, confirm that the events are seizures, and classify the seizures [1].
• Brain Magnetic Resonance Imaging (MRI): MRI is a standard of care for infants with epilepsy and can help narrow the differential diagnosis and tailor the subsequent workup [15].

Additionally, genetic testing may be recommended in infants with a family history of similar seizures in the newborn and infant, as it can guide the diagnosis and management of BFIE [2]. The identification of a novel SCN2A mutation in a family with infantile seizures with onset between 6-8 months provides further confirmation that the gene is associated with BFIE [4].

It's worth noting that differential diagnoses for BFIE include benign familial neonatal-infantile seizures (BFNIS) and other conditions, which can be ruled out through comprehensive diagnostic testing [3][9].

Treatment Options for Benign Familial Infantile Seizures

Benign familial infantile epilepsy (BFIE) is a genetic epileptic syndrome characterized by the occurrence of afebrile repeated seizures in healthy infants. The treatment options for BFIE are limited, and the primary goal is to prevent or reduce the frequency and severity of seizures.

• Anti-seizure medications: Treatment with antiepileptic medications may be initiated to prevent the occurrence or reduce the length of the period of status epilepticus. Carbamazepine (Carbatrol, Tegretol) and phenobarbital are commonly used medications for treating BFIE.
• Low-dose lacosamide: Low-dose lacosamide has been shown to be effective in reducing seizure frequency in children with benign infantile epilepsy.
• Levetiracetam: Levetiracetam (Keppra) is another antiepileptic medication that may be used to treat BFIE.

It's essential to note that the treatment approach for BFIE should be individualized and tailored to the specific needs of each child. The International League Against Epilepsy (ILAE) recommendations for the management of benign infantile convulsions list carbamazepine, phenobarbital, and other medications as potential treatment options.

Differential Diagnoses for Benign Familial Infantile Seizures

Benign familial infantile seizures (BFIS) can be challenging to diagnose, and a thorough differential diagnosis is essential to rule out other conditions. The following are some of the key differential diagnoses to consider:

• Aseptic Meningitis: This condition presents with fever, headache, and stiff neck, which can mimic the symptoms of BFIS.
• Frontal Lobe Epilepsy: This type of epilepsy involves seizures that originate from the frontal lobe of the brain and can present with similar symptoms to BFIS.
• Infantile Epileptic Spasms Syndrome (West Syndrome): This is a rare condition characterized by infantile spasms, which are brief, sudden contractions of the muscles. It requires prompt medical attention.
• Intellectual Disability: In some cases, BFIS can be associated with intellectual disability, so it's essential to consider this in the differential diagnosis.

According to [3], genetic studies have led to the identification of specific genes associated with BFIS, which can aid in the differential diagnosis. However, a comprehensive evaluation by a healthcare professional is necessary to determine the correct diagnosis and develop an effective treatment plan.
