Benign Familial Infantile Convulsions

Benign familial infantile convulsions are seizures that start in otherwise healthy infants in the first year of life, run in families, and tend to stop on their own over months. Many cases are linked to changes in the PRRT2 gene; the condition is often called self-limited (familial) infantile epilepsy because development is usually normal and seizures resolve, though some children can have related movement disorders later in life. Diagnosis relies on the seizure pattern, family history, and—when available—genetic testing. PMC+2Frontiers+2 Seizures are typically focal (start in one area of the brain), may cluster over days, and can secondarily generalize. Onset is most often between 3–12 months, and long-term outlook is usually good. However, as with any epilepsy, a neurologist should evaluate the child to exclude other causes. JAMA Network PRRT2 variants account for a large proportion of familial cases and can overlap with paroxysmal kinesigenic dyskinesia (PKD) or combined phenotypes (ICCA). Knowing the gene helps counseling and sometimes drug choice (sodium-channel blockers can work well). NCBI+2ScienceDirect+2

Benign familial infantile convulsion is an epilepsy syndrome that starts in infancy (usually around 3–12 months). A baby who is otherwise healthy has repeated, short seizures that often come in clusters over a few days. Between seizures the child behaves and develops normally. Brain scans and EEG between seizures are usually normal. The seizures almost always stop on their own within months to a couple of years, and long-term development is typically normal. Because the condition tends to run in families and naturally goes away, experts now use the name self-limited (familial) infantile epilepsy (SeLIE/SeLFIE) instead of “benign.” Epilepsy Diagnosis

Other names

Doctors, papers, and websites use different names for the same syndrome. Common synonyms include: benign familial infantile seizures (BFIS), benign familial infantile epilepsy (BFIE), benign familial infantile convulsions (BFIC), and modern terminology self-limited (familial) infantile epilepsy (SeLIE/SeLFIE). The older term “benign” was updated to “self-limited” in ILAE classifications to emphasize the usual spontaneous remission. NCBI

Types

1. Familial infantile epilepsy (SeLFIE). A parent or close relative had the same infant-onset seizures. The pattern is autosomal dominant: a single gene change can be passed from generation to generation, often with reduced penetrance (some carriers never have seizures). Epilepsy Diagnosis

2. Self-limited infantile epilepsy (SeLIE, “sporadic”). The clinical picture is the same, but there is no family history—often because the genetic change happened de novo (new in the child). Epilepsy Diagnosis

3. Neonatal-infantile overlap (self-limited familial neonatal-infantile epilepsy). Seizures start a little earlier (from the first days of life up to ~6 months) and are most often linked to SCN2A variants; it overlaps but is a distinct label. Orpha+1

4. PRRT2-related spectrum (ICCA). Some families have infantile seizures plus later paroxysmal movement spells (paroxysmal kinesigenic dyskinesia); this combination is called infantile convulsions with choreoathetosis (ICCA) and shares the same core genetic cause. Frontiers+1

Causes

Core cause:

1. PRRT2 gene variants (most common). A change (often a small duplication called c.649dupC) disrupts PRRT2, a nerve-cell protein that helps control neurotransmitter release at synapses. This lowers the “seizure threshold” in infancy, when brain circuits are rapidly maturing. Inheritance is usually autosomal dominant. PMC+2ScienceDirect+2

Other genes in the same self-limited infantile spectrum:

1. SCN2A variants (sodium channel). Some families with neonatal-infantile onset have SCN2A changes; many of these cases are self-limited. Orpha+1
2. SCN8A variants (rare). A minority of families with infantile-onset self-limited epilepsy have SCN8A changes. Epilepsy Diagnosis

Genetic patterns and mechanisms that “explain why” in families:

1. Autosomal dominant inheritance with variable penetrance. A parent may carry the variant without ever having seizures, yet pass it on. Epilepsy Diagnosis
2. De novo mutation. The gene change can appear for the first time in the child (no prior family history). Epilepsy Diagnosis
3. Synaptic release dysregulation. PRRT2 is involved in vesicle release; its loss of function can make neuronal firing less stable in infancy. MedlinePlus

Why seizures cluster in practice (common precipitating factors):

The underlying cause is genetic, but many real-life things can trigger clusters in infants who already have SeLIE.

1. Minor viral illnesses (runny nose, tummy upsets) can lower seizure thresholds for a few days. (General pediatric epilepsy guidance recognizes illness-related seizure provocation.) NICE

2. Fever (even when febrile seizures are not the syndrome itself) can be a stressor in a genetically predisposed infant. NICE

3. Sleep loss/disruption during teething, travel, or illness can trigger spells in susceptible infants. NICE

4. Electrolyte shifts (e.g., low sodium) are well-known seizure precipitants and are checked when clinically suspected. ACEP

5. Low blood sugar during intercurrent illness or prolonged fasting can precipitate a seizure. piernetwork.org

6. Dehydration (especially with vomiting/diarrhea) may contribute via electrolytes and glucose changes. Children’s Health Queensland

7. Medications or toxins that lower seizure threshold (e.g., certain antidepressants or stimulants—rare in infants but relevant via exposures). NCBI

8. Rapid temperature changes/overheating can act as nonspecific stressors in some children with epilepsy. NICE

9. Vaccination-related fever (fever itself, not the vaccine) can be a short-term trigger in predisposed infants. (Handled as a routine fever; vaccination remains recommended.) NICE

10. Strong startle or sudden movement later in childhood in ICCA families may provoke movement spells; it shares the PRRT2 basis with the infantile seizures. Pediatric Neurology Briefs

11. Family-specific modifiers. Even in the same family, some carriers have more frequent clusters than others, reflecting other small genetic/environmental modifiers. Frontiers

12. Brain development stage. The infant brain has exuberant synaptic connections; as circuits mature, seizures remit—hence “self-limited.” Epilepsy Diagnosis

13. De novo copy-number or regional changes around 16p11.2 that affect PRRT2 in some cases. ScienceDirect

14. Unknown/undetected genetic factors in a minority with SeLIE features but negative testing for known genes. Epilepsy Diagnosis

Symptoms

1. Sudden stiffening or jerking on one side of the body (a focal motor seizure). The head or eyes may turn to one side. Epilepsy Diagnosis

2. Impaired awareness for seconds to minutes; the baby becomes still, stares, or is briefly unresponsive. Epilepsy Diagnosis

3. Clustering over a day or two. Several seizures can happen in 24–72 hours, then nothing for weeks. Epilepsy Diagnosis

4. Brief bluish color around the lips during a longer spell (due to breathing pause), followed by quick recovery. Epilepsy Diagnosis

5. Post-seizure sleepiness; the baby may nap after an event, then wake normally. Epilepsy Diagnosis

6. Normal behavior between seizures. Feeding, smiling, playing, and milestones continue as usual. Epilepsy Diagnosis

7. Onset in late infancy (most often around 6 months, range 3–20 months). Epilepsy Diagnosis

8. No fever at the time of typical spells (these are afebrile seizures), though illness can be nearby in time. rarediseases.info.nih.gov

9. Occasional vomiting or pallor during a focal autonomic seizure. Epilepsy Diagnosis

10. Seizures that can begin in one area and spread to both sides (focal to bilateral tonic-clonic). Epilepsy Diagnosis

11. Normal head size and neurological exam at routine visits. Epilepsy Diagnosis

12. Normal development (sitting, crawling, babbling) over time. Epilepsy Diagnosis

13. Family history of similar infant seizures in a parent, aunt/uncle, or sibling. Epilepsy Diagnosis

14. No chronic daily symptoms. This is not a daily condition; it flares and then remits. Epilepsy Diagnosis

15. Resolution in months to a couple of years. Most children grow out of it and do not have lasting problems. Epilepsy Diagnosis

Diagnostic tests

Physical examination (bedside assessments)

1. Full pediatric exam to confirm a healthy infant, check growth, and look for infection sources or signs that point to another epilepsy syndrome. NICE

2. Detailed neurological exam (muscle tone, reflexes, eye movements) to ensure the nervous system is normal between seizures. NICE

3. Developmental screening at visits (milestones, social interaction) to confirm normal progress. Developmental delay suggests a different diagnosis. Epilepsy Diagnosis

4. Head-circumference measurement to screen for micro- or macrocephaly that would redirect evaluation. NICE

5. Skin, eye, and organ exam to look for neurocutaneous or systemic clues (none are expected in SeLIE). NICE

“Manual” or bedside tests (simple checks done quickly)

6. Capillary blood glucose (finger-stick). Low sugar provokes seizures and is easy to rule out during/after an event. piernetwork.org

7. Vital signs and temperature. To identify fever or illness that might temporarily lower the seizure threshold. NICE

8. 12-lead ECG. Helps exclude rare cardiac rhythm problems that can mimic seizures or cause transient loss of consciousness. Some pediatric pathways recommend an ECG after a first afebrile seizure. piernetwork.org

9. Caregiver video of events (smartphone). Clear video helps confirm seizure type and rule out mimics; it is strongly encouraged in modern practice. NICE

10. Focused electrolyte check at the bedside/blood gas if the story suggests dehydration or metabolic upset. Children’s Health Queensland

Laboratory and pathological tests (used selectively)

11. Serum electrolytes (Na, K, Ca, Mg) when clinically indicated (e.g., persistent altered state, dehydration, very young age). Routine testing has low yield in well infants who rapidly return to baseline. Children’s Health Queensland+1

12. Serum glucose (venous confirmation) if low bedside glucose or concerning history. piernetwork.org

13. Infection work-up only when exam suggests it (e.g., meningitis signs)—not routine in classic SeLIE. NICE

14. Genetic testing: targeted PRRT2 analysis (or epilepsy gene panel). Confirms the most common cause, informs counseling, and may avoid unnecessary imaging. NCBI+1

15. SCN2A/SCN8A analysis when the story fits neonatal-infantile overlap or PRRT2 is negative. Epilepsy Diagnosis

Electrodiagnostic tests

16. Standard EEG (awake/asleep). Background is typically normal; ictal EEG, if captured, shows focal onset, often from temporal/posterior regions. A normal interictal EEG supports SeLIE; abnormal slowing suggests looking for other causes. Epilepsy Diagnosis

17. Video-EEG monitoring when spells are frequent or the diagnosis is uncertain; it links behavior and EEG changes to confirm seizure type. NICE

18. Amplitude-integrated EEG (aEEG) is mainly neonatal; rarely needed here but may be used in very young infants when continuous EEG is limited. NICE

Imaging tests

19. Brain MRI (preferred imaging). In classic familial cases with typical EEG/age and normal exam, MRI is often normal and may not be required. If red flags or atypical features exist, MRI is done to exclude structural causes. Epilepsy Diagnosis+1

20. Head CT (urgent settings only). Reserved for trauma, suspected bleeding, or when MRI is not immediately available and a serious cause is suspected. Otherwise avoided to limit radiation in infants. NICE

Non-pharmacological treatments (therapies & others)

1. Seizure first-aid training for caregivers
   Learn what to do during a seizure—stay, keep the child safe, and turn to the side to keep the airway clear. This prevents injuries and reduces fear. Mechanism: practical steps minimize hazards and support breathing until the seizure stops. Epilepsy Foundation+1

2. Structured sleep routine
   Regular, adequate sleep can reduce seizure tendency by stabilizing brain excitability. Purpose: lessen sleep-deprivation triggers. Mechanism: consolidated sleep lowers cortical hyperexcitability in many epilepsies. Pediatrics Publications

3. Fever management plan
   Prompt antipyretic use and hydration when febrile illnesses occur. Purpose: reduce fever-related lowering of seizure threshold. Mechanism: fever can transiently increase neuronal firing; controlling it may reduce provocation. Pediatrics Publications

4. Illness prevention (hand hygiene, vaccines per schedule)
   Keeping infections down reduces fever-related seizures. Mechanism: fewer inflammatory/fever episodes = fewer physiologic triggers. (Follow national immunization schedules.) Pediatrics Publications

5. Avoid known individual triggers
   For some, flashing lights, sleep loss, or acute stress can trigger events. Identifying and avoiding personal triggers reduces episodes. Mechanism: trigger avoidance reduces cortical hyper-synchrony. Pediatrics Publications

6. Safe home setup
   Padding sharp furniture edges, never bathing unattended, and supervising during high-risk activities. Purpose: injury prevention. Mechanism: environmental modification decreases trauma risk if a seizure happens. CDC

7. Ketogenic diet (KD) via pediatric epilepsy team
   In drug-resistant epilepsy, KD can reduce seizures. Purpose: metabolic therapy. Mechanism: ketosis alters brain fuel use and neurotransmitters, stabilizing networks. (Usually not needed in typical BFIC.) PubMed+1

8. Modified Atkins Diet (MAD) / Low-Glycemic Index Treatment
   Less strict alternatives that can cut seizures in some children when supervised. Mechanism similar to KD—mild ketosis and glucose stability. PMC+1

9. Caregiver stress-reduction & counseling
   Education and support lower anxiety and improve adherence to safety plans. Mechanism: reduces stress-related sleep loss and improves consistent care. Epilepsy Foundation

10. Emergency plan & rescue-medication teaching
    Create a written plan (when to call emergency services; when/how to give rescue meds if prescribed). Mechanism: faster response shortens prolonged events and complications. Epilepsy Foundation

11. Developmental surveillance
    Even when prognosis is good, track milestones and address delays early. Mechanism: early therapy optimizes outcomes if issues appear. PMC

12. Illness hydration & nutrition
    Small, frequent fluids and balanced nutrition during sickness support recovery and reduce metabolic stress. Mechanism: stable glucose and electrolytes support neuronal stability. Pediatrics Publications

13. Avoid unsupervised swimming & height risks
    Use life jackets, close supervision near water; avoid bunk beds until seizure-free. Mechanism: reduces drowning/fall injury risk. CDC

14. Family genetic counseling
    Explains inheritance (often autosomal dominant with variable penetrance) and helps future planning/testing. Mechanism: informed decisions and earlier recognition. NCBI

15. Sick-day seizure diary
    Track clusters, illnesses, sleep, and potential triggers. Mechanism: pattern recognition informs prevention and treatment adjustments. Pediatrics Publications

16. Avoid unsupervised flashing-screen exposure if photosensitive
    Rare in BFIC, but sensible if a pattern is noticed. Mechanism: reduce photic-driven cortical synchronization. Pediatrics Publications

17. CPR/first-aid class for household
    Confidence and skills reduce panic and improve safety responses. Mechanism: rapid, appropriate aid during events. Epilepsy Foundation

18. School/daycare care plan
    Share first-aid steps and medication instructions with caregivers. Mechanism: consistent, timely responses outside home. Epilepsy Foundation

19. Age-appropriate car seat & bath safety
    Buckling/carseat use and never leaving an infant alone in bath. Mechanism: prevents secondary injuries. CDC

20. Follow-up with pediatric neurology
    Regular reviews to confirm self-limited course, adjust medicines, and revisit genetic questions. Mechanism: proactive monitoring ensures safe taper when appropriate. Frontiers

Drug treatments

Drug choice, dose, and age appropriateness must be individualized by a pediatric neurologist. Some labels specify minimum ages/indications that may be older than infancy; off-label use in infants is sometimes considered by specialists based on syndrome and risk–benefit. Always follow your clinician’s advice and the latest label. Pediatrics Publications

1. Carbamazepine (Tegretol) – Sodium-channel blocker
   Often effective for PRRT2-related infantile epilepsy. Typical oral forms include tablets, chewables, suspension; dosing is weight-based and titrated. Purpose: stop focal seizures and clusters. Mechanism: stabilizes inactivated sodium channels to reduce rapid firing. Common adverse effects include sleepiness, dizziness, rash; rare but serious: blood dyscrasias, Stevens–Johnson syndrome (screen ancestry-related HLA risk where relevant). PMC+2FDA Access Data+2

2. Oxcarbazepine (Trileptal) – Sodium-channel blocker
   Used for focal seizures; available as liquid and tablets. Purpose: similar to carbamazepine with fewer drug interactions. Mechanism: active metabolite blocks voltage-gated sodium channels. Watch for low sodium and rash; pediatric adverse-event tables guide monitoring. FDA Access Data+1

3. Levetiracetam (Keppra) – SV2A modulator
   Approved for partial-onset seizures in patients 1 month and older (IV/oral); widely used in infants for various focal epilepsies. Purpose: broad-spectrum antiseizure effect with convenient dosing. Mechanism: binds SV2A to reduce neurotransmitter release. Watch for irritability/behavioral changes; dosing adjusted for renal function. FDA Access Data+1

4. Topiramate (Topamax) – Multiple mechanisms
   Used for focal/generalized seizures; sprinkle capsules help in pediatrics. Purpose: adjunct or alternative therapy. Mechanism: blocks sodium channels, enhances GABA, antagonizes AMPA/kainate, weak carbonic anhydrase inhibition. Side effects: appetite/weight loss, metabolic acidosis, kidney stones; dosing titrated slowly. FDA Access Data+1

5. Lamotrigine (Lamictal) – Sodium-channel blocker/glutamate release inhibitor
   Useful for focal seizures; requires slow titration due to serious rash risk. Purpose: maintenance therapy when tolerated. Mechanism: stabilizes membranes and reduces excitatory transmission. Side effects: rash (rarely SJS/TEN), dizziness, nausea. FDA Access Data+1

6. Valproic acid/divalproex (Depakene/Depakote) – Broad-spectrum
   Effective for many seizure types but use in children <2 years carries higher hepatotoxicity risk and must be carefully weighed by specialists. Purpose: reserved when benefits outweigh risks. Mechanism: increases GABA and has multiple channel effects. Major warnings: hepatotoxicity, pancreatitis; teratogenicity (relevant later in life). FDA Access Data+1

7. Clobazam (Onfi) – Benzodiazepine
   Adjunctive therapy (e.g., Lennox-Gastaut); sometimes used short-term for clusters per specialist. Purpose: enhance inhibition. Mechanism: positive allosteric modulator of GABA-A. Adverse effects: sedation, tolerance, dependence; schedule IV. FDA Access Data+1

8. Phenobarbital / Phenobarbital sodium (SEZABY—neonatal IV) – Barbiturate
   Used acutely in neonatal seizures; chronic use limited by sedation/cognitive effects. Purpose: stop severe early-life seizures under specialist care. Mechanism: GABA-A facilitation. Warnings: respiratory depression, dependence. FDA Access Data

9. Lacosamide (Vimpat) – Enhances slow inactivation of sodium channels
   Adjunct in focal epilepsy (older pediatric ages on label); used by specialists when others fail. Side effects: dizziness, PR-interval prolongation. FDA Access Data+1

10. Clonazepam – Benzodiazepine
    Sometimes used short-term for clusters; sedation limits long-term use. Mechanism: GABA-A enhancement. (FDA labeling available; class effects similar to clobazam.) Pediatrics Publications

11. Diazepam (rectal/ nasal rescue) – Rescue benzodiazepine
    For prolonged seizures per plan from neurologist—caregivers trained to administer. Mechanism: rapid GABA-A potentiation aborts seizures. (FDA-approved rescue formulations exist; follow label/clinician guidance.) Default

12. Midazolam (intranasal/buccal rescue) – Rescue benzodiazepine
    Alternative to diazepam for out-of-hospital treatment of prolonged seizures—per physician plan. Mechanism: fast GABA-A potentiation. Default

13. Carbamazepine XR/chewable/suspension – Formulation flexibility
    Chewables and suspension help accurate infant dosing under specialist titration; boxed safety and interaction cautions still apply. FDA Access Data

14. Oxcarbazepine oral suspension – Pediatric-friendly formulation
    Improves adherence; monitor sodium and rash. FDA Access Data

15. Levetiracetam oral solution & IV – Seamless transition
    Allows hospital-to-home dosing continuity; monitor behavior. FDA Access Data

16. Topiramate sprinkle capsules – Ease of swallowing
    Can be opened and mixed with soft food (do not chew granules); titrate slowly. FDA Access Data

17. Lamotrigine ODT/chewable – For children who cannot swallow tablets
    But strict slow titration remains essential to reduce rash risk. FDA Access Data

18. Valproate ER (older children/adolescents when appropriate) – Once-daily option
    Specialist-led only; heed boxed warnings. FDA Access Data

19. Rescue plan with benzodiazepine per AES guidance – Not daily therapy
    A written plan clarifies when to administer and when to call emergency services. Default

20. Therapy review and taper – Medication minimization
    Because BFIC is self-limited, clinicians often taper off antiseizure medicines after a seizure-free period, if safe. Mechanism: avoid unnecessary exposure. Pediatrics Publications

Dietary molecular supplements

1. Vitamin D (e.g., 400–1000 IU/day per clinician)
   Used to maintain bone health in children on antiseizure meds; some studies suggest seizure reduction when deficiency is corrected. Mechanism: neurosteroid effects, anti-inflammatory pathways. Evidence is mixed; supplementation to sufficiency is reasonable. MDPI+2PMC+2

2. Omega-3 fatty acids (EPA/DHA) (typical pediatric doses vary; clinician-guided)
   Trials show inconsistent seizure reductions; some low-dose studies suggested benefit, others showed no effect. Mechanism: membrane stabilization and anti-inflammatory signaling. Use only if approved by clinician. jnnp.bmj.com+2PubMed+2

3. Magnesium (dose individualized; avoid excess)
   Small/heterogeneous data suggest possible benefit in specific contexts; robust pediatric epilepsy data are limited. Mechanism: NMDA receptor modulation and membrane stabilization. MDPI+1

4. Multivitamin to cover KD/MAD gaps (if on ketogenic/MAD)
   Diet therapies often require supplements (vitamins, minerals, selenium) to prevent deficiencies during carbohydrate restriction. Mechanism: replacement of restricted-diet shortfalls. Epilepsy Foundation+1

5. Calcium (if dietary intake is low, especially with vitamin D)
   Supports bone health in children on long-term ASMs or diet therapy; not a seizure medicine. Mechanism: skeletal mineralization. JAMA Network

6. Selenium (only if diet therapy team recommends)
   In ketogenic programs, selenium deficiency can occur; supplementation prevents cardiomyopathy risk. Mechanism: antioxidant enzyme function. PubMed

7. Carnitine (specialist-directed)
   Sometimes considered with valproate therapy to support fatty-acid metabolism; evidence for seizure control is limited. Mechanism: mitochondrial β-oxidation cofactor. FDA Access Data

8. Zinc (only if deficiency confirmed)
   General neurodevelopment support; no clear seizure-reduction evidence. Mechanism: cofactor in synaptic enzymes. Pediatrics Publications

9. B-complex (including folate)
   Used to correct deficiencies from restrictive diets or poor intake; not an antiepileptic by itself (pyridoxine-dependent epilepsy is a different, rare disorder). JAMA Network

10. Electrolyte maintenance during illness
    Oral rehydration with appropriate salts/glucose supports stable physiology; not a drug, but reduces metabolic seizure stressors. Pediatrics Publications

---

Immunity booster / regenerative / stem cell drugs

There are no FDA-approved “immunity booster,” regenerative, or stem-cell drugs to treat benign familial infantile convulsions. Using such products outside clinical trials is not recommended and may be risky. If you see claims online, discuss them with a pediatric neurologist and check trial registries. Safer supportive strategies include routine vaccinations, nutrition, and sleep hygiene. Default

---

Surgeries

Surgery is almost never needed for BFIC, because seizures are self-limited and children have normal development. These procedures are listed for context in difficult focal epilepsies when a clear brain focus is found—not typical of BFIC: focal resection (remove a small seizure focus), laser ablation, corpus callosotomy (disconnects hemispheres to limit spread), hemispherotomy (for catastrophic hemispheric epilepsy), and vagus nerve stimulation (VNS) (implant to reduce seizure frequency). These decisions follow advanced testing and guidelines. Default

Preventions

1. Keep a seizure first-aid plan visible at home and daycare. Epilepsy Foundation

2. Prioritize consistent sleep and naps. Pediatrics Publications

3. Manage fevers early and keep fluids up during illness. Pediatrics Publications

4. Keep vaccinations up to date. Pediatrics Publications

5. Supervise bathing and water play; use life jackets near water. CDC

6. Child-proof edges/heights; use car seats correctly. CDC

7. Consider sunglasses / positioning if photosensitivity suspected. Pediatrics Publications

8. Share a written rescue-med plan with caregivers. Epilepsy Foundation

9. Keep a seizure diary to spot patterns. Pediatrics Publications

10. Maintain regular neurology follow-ups and revisit the need for medicines as the child grows. Frontiers

When to see doctors

Seek urgent care for seizures lasting >5 minutes, repeated seizures without recovery, breathing problems, injury, color change, or if prescribed rescue medicine fails—these are standard “red flags.” Otherwise, schedule neurology visits for new clusters, developmental concerns, medication side effects, or before changing doses. Families should also get genetic counseling to understand PRRT2 and related phenotypes. CDC+2Epilepsy Foundation+2

---

Foods to eat & to avoid

Eat more (general healthy pattern; or per diet therapy if prescribed): fruits, vegetables, whole-grains (unless on KD/MAD), lean proteins, dairy (or fortified alternatives), nuts/seeds, adequate fluids, and dietitian-approved fats if on KD/MAD (e.g., olive oil, MCT oil), plus micronutrient-rich foods to support growth. Avoid or limit: ultra-processed sugary snacks and drinks, energy drinks/caffeine in older kids, alcohol in adolescents, fad “supplements” promising seizure cures, and rapid dieting practices; on KD/MAD specifically, avoid unplanned carbs that break ketosis—work closely with the diet team. JAMA Network+1

FAQs

1) Is BFIC the same as infantile spasms?
No. BFIC involves focal seizures in clusters with generally good prognosis; infantile spasms are a different emergency syndrome treated with ACTH or vigabatrin. JAMA Network+1

2) Will my child outgrow it?
Most families see seizures stop within months to a couple of years, with normal development, though follow-up is important. PMC

3) Is PRRT2 testing useful?
Yes—commonly positive in familial cases; it helps counseling and, sometimes, drug selection. NCBI

4) Which medicines work best?
Many children respond to sodium-channel blockers like carbamazepine/oxcarbazepine; clinicians also use levetiracetam and others based on age and safety. American Academy of Neurology

5) Are these drugs approved for infants?
Some are (e.g., levetiracetam is labeled down to 1 month for partial-onset seizures). Others may be off-label but commonly used by specialists—follow your neurologist’s plan and FDA labels. FDA Access Data

6) Do diets cure BFIC?
Diet therapies can help drug-resistant epilepsy; BFIC is typically self-limited and often managed medically or with watchful waiting. JAMA Network

7) Are “stem cell” or “immune booster” drugs available?
No—there are no FDA-approved stem-cell or immune-booster drugs for BFIC. Avoid unproven therapies. Default

8) Is rescue medicine needed at home?
Your neurologist may prescribe rectal/nasal benzodiazepine and train you to use it for prolonged seizures. Default

9) Can my child swim?
Yes—with constant close supervision and life jackets near open water; never bathe unsupervised. CDC

10) Will this affect school later?
Most children do well; keep a care plan with teachers and review as needed. PMC

11) Is driving relevant later?
Rules vary; position statements recommend seizure-free intervals and individualized assessment when age-appropriate. Default

12) Should siblings be tested?
Genetic counseling can discuss family testing, especially if there’s a strong history. NCBI

13) Are there long-term movement issues?
Some PRRT2 families have paroxysmal kinesigenic dyskinesia (PKD) or ICCA later; most children still do well. NCBI

14) How long will medicines continue?
If seizure-free and developing normally, clinicians often consider gradual taper after a safe period. Pediatrics Publications

15) What follow-ups are essential?
Regular neurology visits to review diaries, growth, development, and adjust plans; revisit genetic questions if needed. Frontiers
