Autosomal Dominant Nocturnal Frontal Lobe Epilepsy (ADNFLE)

Autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) is a rare type of focal epilepsy where brief, sudden motor (movement) seizures happen mainly during sleep, usually in clusters in the first half of the night. The movements can be small (like abrupt arousals) or very dramatic (thrashing, bicycling, kicking, dystonic postures), often with loud sounds or vocalization. Seizures start and stop abruptly, commonly last under 2 minutes, and many people stay partly aware or recall parts of the event. Daytime seizures can occur but are less common. The condition often runs in families in an autosomal dominant pattern—meaning a change in one copy of a certain gene can be enough to cause the syndrome—although sporadic (non-familial) cases also exist. The disorder was historically linked to the frontal lobe of the brain, but newer research shows the seizure network can extend beyond a single spot and includes genetic and structural causes; because events arise from sleep and feature strong motor behavior, the preferred modern name is sleep-related hypermotor epilepsy (SHE) or ADSHE when inherited. Epilepsy Diagnosis+2International League Against Epilepsy+2

Sleep-related hypermotor epilepsy (SHE) is a focal epilepsy where brief, stereotyped (repeat-the-same-way) motor seizures happen mostly from sleep, often in clusters, with abrupt start and stop (usually <2 minutes). Movements can be sudden sitting up, thrashing, cycling legs, grabbing, pelvic thrusting, yelling or gasping. Awareness can be partly preserved. Many families show autosomal dominant inheritance (one changed gene copy can cause the disorder), with genes involving nicotinic acetylcholine receptors (e.g., CHRNA4, CHRNB2, CHRNA2) and others (e.g., KCNT1, DEPDC5). The name changed from ADNFLE to SHE because seizures can arise from areas beyond the frontal lobe and because sleep is the key trigger. Diagnosis is clinical, supported by video-EEG when possible. Prognosis is often good with medicine (not always); ~30% may be drug-resistant and need advanced options. Taylor & Francis Online+4PMC+4International League Against Epilepsy+4

Other names

• Sleep-related hypermotor epilepsy (SHE) – current name for the syndrome. Epilepsy Diagnosis+1

• Autosomal-dominant sleep-related hypermotor epilepsy (ADSHE) – used when inherited in families. NCBI+1

• Nocturnal frontal lobe epilepsy (NFLE) / Autosomal dominant NFLE (ADNFLE) – earlier terms still seen in older papers and in some clinical notes. OUP Academic

Types

1. By cause

• Genetic (ADSHE): due to pathogenic variants in nicotinic acetylcholine receptor subunit genes CHRNA4, CHRNB2, CHRNA2, and in other genes such as KCNT1 and DEPDC5 (and less commonly in mTOR-pathway partners NPRL2/NPRL3). These change brain excitability during sleep and make motor seizures more likely. MedLink+6MedlinePlus+6MedlinePlus+6

• Structural (lesional) SHE: due to an identifiable brain lesion (often focal cortical dysplasia) in or near frontal lobe networks; some DEPDC5-related cases also show cortical malformation. NCBI

• Unknown cause (non-lesional, non-genetic): clinical picture fits SHE but no pathogenic variant or lesion is found. Epilepsy Diagnosis

2. By seizure semiology (what it looks like): classic nocturnal hypermotor events range from paroxysmal arousals, asymmetric tonic/dystonic postures, to hyperkinetic thrashing or bicycling; patterns within a person are usually stereotyped and very brief. Epilepsy Diagnosis+1

3. By family pattern

• Familial (autosomal dominant) ADSHE/ADNFLE. NCBI

• Sporadic SHE (no family history). Epilepsy Diagnosis

Causes

In this context, “cause” includes proven genetic causes, structural contributors, and common seizure-threshold lowerers that make attacks more likely in people predisposed to SHE.

1. CHRNA4 variants – alter the α4 subunit of the nicotinic acetylcholine receptor (nAChR), changing how brain cells respond to acetylcholine during sleep and promoting brief motor seizures. MedlinePlus

2. CHRNB2 variants – affect the β2 subunit of nAChR and can produce the same phenotype in families. MedlinePlus

3. CHRNA2 variants – affect the α2 subunit and produce ADNFLE/ADSHE in some families. MedlinePlus+1

4. KCNT1 variants – gain-of-function changes increase a sodium-activated potassium current, reducing inhibitory interneuron excitability and disinhibiting networks, which can trigger hypermotor seizures. Frontiers

5. DEPDC5 variants – disrupt a negative regulator of the mTOR pathway; may present as focal epilepsies including SHE and can associate with cortical malformations. NCBI+1

6. NPRL2/NPRL3 variants – partners with DEPDC5 in the mTOR pathway; reported in familial focal epilepsies with sleep-related hypermotor features. MedLink

7. Focal cortical dysplasia (FCD) – a developmental malformation that provides a seizure focus in frontal networks. NCBI

8. Other subtle cortical malformations (e.g., hemimegalencephaly in selected gene-positive cases) can underlie seizures. NCBI

9. Sleep instability – arousals from non-REM sleep foster brief motor seizures in SHE. MedlinePlus

10. Sleep deprivation – lowers seizure threshold and increases seizure clustering at night. (General epilepsy trigger emphasized in SHE reviews.) BioMed Central

11. Alcohol intake, especially evening binges – a known epilepsy trigger that can worsen nocturnal seizures. (Discussed across epilepsy resources and SHE reviews.) BioMed Central

12. Psychological stress – commonly reported trigger for focal epilepsies including SHE. BioMed Central

13. Fever/illness – may transiently lower threshold in predisposed individuals. (General seizure provocation acknowledged in epilepsy guidance.) Epilepsy Foundation

14. Irregular sleep schedules (shift work, jet lag) – disturb NREM stability and can precipitate events. BioMed Central

15. Stimulants or nicotine late at night – can alter cholinergic tone; nicotinic receptor pathway is central in ADSHE genetics. (Mechanistic linkage via nAChR.) MedlinePlus

16. Certain medications that lower seizure threshold (e.g., some antidepressants in high doses) may aggravate seizures in vulnerable patients. (General epilepsy precaution.) Medscape

17. Developmental history with subtle frontal network vulnerability – even with normal scans, network hyperexcitability may exist. Epilepsy Diagnosis

18. Family history / inherited risk – autosomal dominant transmission with variable expression. NCBI

19. Co-existing epilepsy syndromes with shared genes (e.g., DEPDC5-related focal epilepsies) can manifest with SHE semiology in some relatives. NCBI

20. Unknown/idiopathic mechanisms – in many people no single lesion or variant is found despite a classic clinical picture. Epilepsy Diagnosis

Diagnostic tests

Physical examination (bedside/clinic)

1. General & neurologic exam: Doctors look for abnormal movements, weakness, or signs suggesting a structural brain problem. In many with SHE the exam is normal, but it helps exclude other disorders. Epilepsy Diagnosis

2. Sleep and seizure history interview: A structured interview with the person and the bedpartner documents timing (night), clustering, abrupt onset/offset, vocalizations, and stereotypy—key clues that favor SHE over parasomnias. OUP Academic

3. Injury and safety review: Checking for bruises, falls, or hazards in the bedroom; helps judge severity and plan safety steps while diagnosis proceeds. OUP Academic

Manual/bedside assessments

4. Sleep diary / event log: Recording nights with events, bedtime, awakenings, and triggers (sleep loss, alcohol). This low-tech tool maps patterns characteristic of SHE. BioMed Central

5. Home video (if safe): Short phone videos captured by a partner (when feasible) can reveal stereotyped hypermotor patterns that strongly support the diagnosis before lab testing. OUP Academic

6. Standardized questionnaires for nocturnal events: Tools aimed at sorting epilepsy from parasomnias guide the decision to do in-lab video-EEG. American Academy of Neurology

Laboratory / pathological

7. Basic blood tests (metabolic panel, glucose, electrolytes) rule out metabolic triggers that could worsen seizures and guide safe medicine use (e.g., liver/renal function before carbamazepine). Medscape

8. Medication level monitoring (when already on antiseizure drugs): helps confirm adherence and therapeutic range, important because SHE often improves with appropriate dosing. Medscape

9. Genetic testing (multigene epilepsy panel): Looks for CHRNA4, CHRNB2, CHRNA2, KCNT1, DEPDC5 and related genes. A positive result confirms ADSHE in familial cases, informs relatives, and may influence treatment planning. MedlinePlus+2Frontiers+2

Electrodiagnostic

10. Routine scalp EEG (awake & sleep): Often normal between seizures in SHE, but may show interictal spikes or frontal rhythmic changes; lack of clear EEG doesn’t exclude SHE. OUP Academic

11. Overnight video-EEG with polysomnography (PSG): The gold-standard test—combines EEG, video, and sleep sensors to capture typical nocturnal hypermotor seizures from NREM sleep and to distinguish from parasomnias. Ictal scalp EEG may be subtle; the behavioral pattern and sleep stage are key. Epilepsy Diagnosis+1

12. High-density EEG or invasive EEG (SEEG) in selected refractory cases: maps the seizure onset zone when surgery is considered. Epilepsy Diagnosis

Imaging

13. 3-Tesla epilepsy-protocol MRI: Searches for subtle focal cortical dysplasia or other malformations in frontal networks; many patients have normal MRI, but when present, lesions guide therapy. NCBI

14. FDG-PET (interictal): May show regional hypometabolism that supports localization when MRI is normal. Epilepsy Diagnosis

15. Ictal SPECT (when feasible): Captures blood-flow increase at seizure onset to help localize the network driving hypermotor events. Epilepsy Diagnosis

Additional evaluations

16. Neuropsychological testing: Establishes a cognitive baseline, screens attention/memory affected by poor sleep, and assists presurgical planning. Epilepsy Diagnosis

17. Sleep medicine assessment for co-existing sleep disorders (e.g., sleep apnea): treating comorbid sleep issues can reduce arousals and help seizure control. BioMed Central

18. Safety assessment of the sleep environment: Clinically recommended to prevent injury (bedside padding, floor mattress, remove sharp furniture). OUP Academic

19. Family screening where appropriate: If a pathogenic variant is found, targeted testing of relatives can identify others at risk and guide counseling. NCBI

20. Multidisciplinary epilepsy conference review: Complex or refractory cases benefit from team review (neurology, epilepsy surgery, neurophysiology, genetics) to finalize diagnosis and treatment plan. Epilepsy Diagnosis

Non-pharmacological treatments (therapies & others)

1. Strict sleep schedule – Go to bed and wake up at the same time daily, target adequate sleep for age, avoid shift work when possible. Purpose: reduce sleep deprivation, a common seizure trigger. Mechanism: stabilizes circadian rhythm, lowers cortical excitability that rises with lost sleep. Epilepsy Foundation

2. Treat sleep disorders (OSA, RLS, insomnia) – Screen for snoring, witnessed apneas, restless legs; treat (weight, CPAP, iron, CBT-I). Purpose: remove nocturnal triggers. Mechanism: improves oxygenation and arousal stability; fewer arousals mean fewer sleep-onset seizures. Epilepsy Foundation

3. Stress management (CBT, mindfulness, breathing) – 10–20 minutes daily. Purpose: lower stress-related spikes in seizures. Mechanism: reduces sympathetic drive and hyperventilation that modulate cortical excitability. Epilepsy Foundation

4. Regular, moderate exercise – Walking, cycling, yoga most days. Purpose: better sleep quality, mood, and seizure threshold. Mechanism: exercise improves sleep architecture and neurochemical balance. Epilepsy Foundation

5. Avoid alcohol binges & recreational drugs – Especially evenings. Purpose: prevent withdrawal-related and sleep-disrupting seizures. Mechanism: alcohol fragments sleep, alters GABA/glutamate balance. Epilepsy Foundation

6. Caffeine timing & limits – Avoid high caffeine late day. Purpose: protect deep sleep. Mechanism: adenosine antagonism delays sleep onset; lighter sleep increases events. Epilepsy Foundation

7. Evening electronics hygiene – Blue-light filters, device-off 60–90 minutes before bed. Purpose: faster sleep onset, deeper NREM sleep. Mechanism: preserves melatonin signaling. Epilepsy Foundation

8. Bedroom safety prep – Low bed, remove sharp edges, padded headboard, safety rails if needed. Purpose: reduce injury during nocturnal hypermotor seizures. Mechanism: environmental harm-reduction. Epilepsy Foundation

9. Seizure first-aid training – Caregivers learn roll-to-side, time events, avoid restraint, call emergency when indicated. Purpose: safer responses; better documentation. Mechanism: reduces complications and supports accurate diagnosis. Epilepsy Foundation

10. Adherence tools – Pill organizers, smartphone reminders. Purpose: prevent missed doses (a leading cause of breakthroughs). Mechanism: steady plasma levels mean steadier cortical inhibition. Epilepsy Foundation

11. Identify personal triggers – Keep a diary (sleep loss, stress, fever). Purpose: reveal patterns to modify. Mechanism: targeted avoidance reduces seizure propensity. Epilepsy Foundation

12. Weight management if OSA – Modest weight loss helps apnea. Purpose: fewer nocturnal arousals. Mechanism: improves airway patency and sleep stability. Epilepsy Foundation

13. Consistent evening meals – Avoid very heavy, very late dinners. Purpose: reduce reflux/fragmented sleep. Mechanism: better NREM continuity lowers seizure likelihood. Epilepsy Foundation

14. Bed-partner video when safe – Short smartphone clips (if advised). Purpose: capture semiology for clinicians. Mechanism: real-world documentation aids diagnosis and treatment tuning. PMC

15. Protect circadian rhythm during travel – Gradual shifts, light exposure timing. Purpose: avoid jet-laged sleep loss. Mechanism: circadian alignment stabilizes neuronal networks. Epilepsy Foundation

16. Mind-body adjuncts (yoga/relaxation) – Gentle evening routines. Purpose: improve sleep depth and anxiety. Mechanism: autonomic balance toward parasympathetic tone. Epilepsy Foundation

17. Education on semiology vs parasomnias – Learn differences between SHE and night terrors. Purpose: faster diagnosis and fewer unsafe restraints. Mechanism: informed responses, better care. PMC

18. Temperature & comfort – Cool, dark, quiet room. Purpose: solid NREM sleep. Mechanism: minimizes arousals that precipitate events. Epilepsy Foundation

19. Medication review for sleep impact – Avoid activating meds late day when possible. Purpose: deeper sleep. Mechanism: reduces cortical hyperarousal. Epilepsy Foundation

20. Dietary therapy under supervision (keto/MAD) – Consider in drug-resistant cases. Purpose: reduce seizures when meds insufficient. Mechanism: ketosis shifts brain energy use and neurotransmission; evidence strongest in refractory epilepsy. PMC+1

Drug treatments

Important: There is no single “SHE-only” drug. Clinicians typically use focal-seizure antiseizure medications (ASMs); carbamazepine has historic benefit in SHE, but choices depend on age, comorbidities, sex/pregnancy plans, interactions, and tolerability. Doses below are common adult ranges—ALWAYS individualized by the treating clinician.

1. Carbamazepine (Tegretol / Carbatrol) – Class: sodium-channel blocker. Dose & timing: often 200–400 mg twice daily (varies/formulations). Purpose: first-line in many focal epilepsies; classic experience in SHE. Mechanism: stabilizes inactivated Na+ channels, damping hyperexcitable neurons. Side effects: dizziness, diplopia, hyponatremia, rash; rare aplastic anemia/agranulocytosis; HLA-B*1502/3101 risk for severe rash in some ancestries; many drug interactions. FDA Access Data+2FDA Access Data+2

2. Oxcarbazepine (Trileptal / Oxtellar XR) – Class: sodium-channel blocker (MHD metabolite). Dose: commonly 300 mg twice daily, titrating to 600–1200 mg twice daily (or XR once daily). Purpose: focal seizures. Mechanism: inhibits voltage-gated Na+ channels.

Side effects: somnolence, dizziness; QT-shortening; interactions (notably with clobazam, phenytoin). FDA Access Data+2FDA Access Data+2

13. Valproate/Divalproex (Depakote) – Class: multiple (GABA, Na+ channels). Dose: individualized (e.g., 250–500 mg twice daily). Note: avoid in pregnancy/people who could become pregnant unless essential due to major fetal risks and cognitive effects. Side effects: weight gain, tremor, liver/pancreas toxicity. FDA Access Data+2FDA Access Data+2

14. Top-up/legacy options (selected): Phenytoin (Dilantin) – effective but with nonlinear kinetics and many interactions; Phenobarbital (sedation); Tiagabine (GABA reuptake inhibitor; limited by AEs); Gabapentin/Pregabalin (less potent for focal epilepsy but may help some). Choice is individualized. FDA Access Data+3FDA Access Data+3FDA Access Data+3

Why carbamazepine is often tried first in SHE: historic reports and series show notable bedtime carbamazepine benefit in many, though not all, patients; nonetheless ~30% remain drug-resistant. Decisions should be personalized. PMC+1

Dietary molecular supplements

1. Omega-3 fatty acids (EPA/DHA) – Dose (studied): ~1.7–2 g/day combined, or lower in some analyses. Function: membrane stabilization, anti-inflammatory. Mechanism: alters neuronal membrane lipids; may modulate ion channels and cytokines. Evidence: mixed—some RCTs show early reductions; others show no benefit or even worse outcomes; recent studies explore dose effects. Seizure Journal+3PubMed+3PMC+3

2. Vitamin D3 – Dose: individualized to correct deficiency (often 1000–5000 IU/day under supervision). Function: bone health on ASMs; possible seizure effect when deficient. Mechanism: neurosteroid actions, anti-inflammatory. Evidence: mixed; some observational/open-label signals vs meta-analysis showing no clear seizure reduction effect—still useful to correct deficiency. American Academy of Neurology+3ScienceDirect+3PubMed+3

3. Magnesium – Dose: varies (e.g., 200–400 mg elemental Mg/day), adjust for renal function. Function: correct deficiency linked to neuronal hyperexcitability. Mechanism: NMDA receptor antagonism; raises seizure threshold when low. Evidence: mechanistic and small studies suggest potential; robust RCT data are limited. PubMed+2PubMed+2

4. MCT oil (supporting ketogenic strategies) – Dose: titrate (e.g., teaspoons with meals) to tolerance. Function: promotes ketone production without full classic keto diet. Mechanism: ketones modulate neurotransmission and mitochondrial function. Evidence: ketogenic and modified Atkins diets can reduce seizures in drug-resistant epilepsy; MCT is one tool under dietitian supervision. PMC

5. Multinutrient support when on keto/MAD – Dose: per dietitian (electrolytes, selenium, carnitine if indicated). Function: avoid deficits. Mechanism: maintains metabolic balance during restrictive diets. Evidence: standard practice in medical ketogenic therapy programs. PMC

6. Melatonin (sleep regularization) – Dose: low (e.g., 2–3 mg at bedtime if clinician approves). Function: stabilize sleep onset. Mechanism: circadian entrainment; indirect seizure benefit via better sleep. Evidence: variable; prioritize behavioral sleep hygiene first. Epilepsy Foundation

7. Thiamine (B1) – Dose: 50–100 mg/day if dietary risk/alcohol use. Function: neuronal energy metabolism. Mechanism: cofactor for carbohydrate metabolism; severe deficiency lowers seizure threshold. Evidence: supportive in deficiency states rather than epilepsy-specific trials. Epilepsy Foundation

8. Folate/B12 check and replace if low – Dose: per labs. Function/mechanism: DNA synthesis & myelin support; some ASMs affect folate metabolism. Evidence: replacement for deficiency is standard care; not an anti-seizure treatment itself. Epilepsy Foundation

9. Electrolyte optimization (Na+, Ca2+) – Dose: medical guidance only. Function: corrects hyponatremia or hypocalcemia that can provoke seizures. Mechanism: stabilizes neuronal firing thresholds. Evidence: clinical common sense; not a supplement to self-start. Epilepsy Foundation

10. Probiotics/anti-inflammatory diet patterns – Function: gut–brain axis and sleep quality. Mechanism: may modulate neuroinflammation/metabolites; evidence preliminary. Evidence: emerging only; not a replacement for ASMs. BioMed Central

Immunity-booster / regenerative / stem-cell drugs

There are no FDA-approved “immunity-booster,” regenerative, or stem-cell drugs to treat epilepsy or SHE. Clinics advertising such injections or “exosomes” are not approved for epilepsy and have generated FDA safety alerts because of harms (infections, injuries) and lack of efficacy. If you ever see such claims, treat them as unproven and potentially dangerous. U.S. Food and Drug Administration+2U.S. Food and Drug Administration+2

---

Procedures/surgeries (what they are & why done)

1. Seizure-focus resection (when a single focus is proven) – After video-EEG, high-resolution MRI, SEEG show one consistent cortical driver, surgeons remove that small region. Why: potential for cure or major reduction when a discrete focus exists. Notes: candidacy in SHE depends on mapping; outcomes vary by location. PMC

2. MRI-guided Laser Interstitial Thermal Therapy (LITT) – A thin laser fiber ablates a precisely targeted focus through a tiny burr hole. Why: minimally invasive option when a focal generator is identified. Evidence: growing data show substantial seizure reductions, with relatively low morbidity vs open resections in selected patients. PMC+1

3. Vagus Nerve Stimulation (VNS) – A pacemaker-like device on the left vagus nerve sends intermittent pulses. Why: add-on for drug-resistant focal epilepsy when resection isn’t feasible. Evidence: ~45–65% achieve ≥50% seizure reduction over time; best effect accrues by ~6 months. PubMed+2Seizure Journal+2

4. Deep Brain Stimulation, anterior nucleus of the thalamus (DBS-ANT) – Electrodes in the ANT of the thalamus modulate seizure networks. Why: adjunctive therapy for adults with drug-resistant focal seizures after medication failure. Regulatory: FDA-approved for this indication. FDA Access Data+1

5. Comprehensive pre-surgical evaluation (Phase I/II monitoring, SEEG) – Not a “surgery” per se, but essential invasive EEG mapping for difficult cases. Why: proves the seizure onset zone and its relation to eloquent cortex, guiding resection or ablation. PMC

Preventions

1. Protect sleep time and quality. 2) Treat snoring/OSA promptly. 3) Avoid missed ASM doses. 4) Avoid alcohol binges and recreational drugs. 5) Manage stress daily (brief relaxation). 6) Keep a personal trigger diary. 7) Secure a safe sleep setup. 8) Time stimulants (limit caffeine late day). 9) Coordinate shift work/travel with your clinician. 10) Keep vaccinations and general health optimized (fever control, illness care) to protect sleep. Epilepsy Foundation

When to see a doctor (or go to emergency)

• Right away / Emergency: seizure >5 minutes, repeated back-to-back without recovery, injury, breathing trouble, first-ever seizure, or pregnancy. Soon: new/worsening night events; injuries during sleep; mood changes on ASMs; daytime spells; suspected sleep apnea; considering pregnancy (pre-conception planning to pick safer ASM plans). Epilepsy Foundation

---

What to eat & what to avoid (plain guidance)

• Eat: regular, balanced meals that support steady energy and good sleep; lean proteins, vegetables, fruits, whole grains, and—if prescribed—a medically supervised ketogenic or modified Atkins plan with proper supplementation. Avoid/Limit: evening caffeine, heavy late meals, and alcohol binges; avoid self-starting restrictive or supplement-heavy regimens without clinician/dietitian guidance, especially if you’re on ASMs with interaction risks. PMC
