Neurology GCC Context NICE / ILAE / GCC Protocols Updated Apr 2026

ILAE Seizure Classification (2017)

Focal Onset

Originates in one hemisphere network. Classified by awareness level and motor/non-motor features.

Focal Aware (FA) Focal Impaired Awareness (FIA) Focal to Bilateral Tonic-Clonic

Previously "partial seizures." If awareness is preserved = formerly simple partial. Impaired awareness = formerly complex partial.

Generalised Onset

Originates in and rapidly engages bilaterally distributed networks. Consciousness almost always impaired.

Tonic-Clonic Absence Myoclonic Atonic Tonic Clonic

Seizure Type Reference

👁

Pre-ictal, Ictal & Post-ictal Phases

Pre-ictal (Aura)
  • Unusual smell/taste/visual disturbance, rising epigastric sensation, deja vu, fear
  • Nursing: document aura type and duration; may be only warning before GTCS
  • Alert duration: seconds to minutes before seizure onset
Ictal Phase
  • Time of seizure onset to end. Observe: type, laterality, eye deviation, automatisms
  • Note exact start time, motor features, colour change, incontinence, tongue biting
  • Do NOT restrain; protect from injury; position laterally if possible
Post-ictal Phase
  • Todd's paresis (focal weakness post-focal seizure), confusion, headache, fatigue, myalgia
  • Recovery position; observe airway; GCS monitoring; glucose check
  • Duration: minutes to hours; document level of consciousness
📋

Seizure Observation & Documentation Guide

Document ALL of the following:
🔴

Status Epilepticus Definition: Seizure lasting >5 minutes OR two or more seizures without full recovery of consciousness between them. A neurological emergency with mortality up to 20% if not treated promptly.

🚨

NICE/GCC SE Management Protocol — Staged Approach

0–5 min
Stage 1 — First Aid
5–20 min
Stage 2 — Benzodiazepine
20–40 min
Stage 3 — 2nd Line AED
>40 min
Stage 4 — Refractory SE
  1. Time the seizure — note exact start time
  2. Position: lateral (recovery) if possible to protect airway; do NOT force mouth open
  3. Protect from injury — padding, remove hazards; do NOT restrain limbs
  4. Supplemental oxygen via face mask 15 L/min
  5. Airway adjunct only if airway compromised — Guedel oropharyngeal airway if tolerated
  6. IV access — establish if not already in situ
  7. Blood glucose — check immediately (hypoglycaemia is reversible cause)
  8. Call for medical help — if seizure at 5 minutes, call emergency team
⚠️

IV access available: Lorazepam 4mg IV (adults) — administer over 2 min. May repeat once after 10 min if no response. Child: Lorazepam 0.1 mg/kg IV.

💉

No IV access: Buccal midazolam 10mg (adults) — first choice in community/no IV. OR Rectal diazepam 10–20mg. Child: Buccal midazolam 0.3 mg/kg (max 10mg).

  • Monitor SpO2 continuously — benzodiazepines cause respiratory depression
  • Be prepared to support airway with BVM if apnoea occurs
  • Continue oxygen; reassess every 5 minutes
  • Diazepam IV: 10–20mg at 2–5mg/min (less preferred — respiratory depression risk)
Levetiracetam IV (preferred)

Dose: 60 mg/kg IV (max 4500mg) over 10 minutes

Advantages: Fewer drug interactions, no cardiac monitoring required, safe in liver disease

Increasing first choice in GCC hospitals due to safety profile

Phenytoin / Fosphenytoin IV

Dose: Phenytoin 20 mg/kg IV at max 50 mg/min

Monitoring required: Continuous ECG, BP every 5 min — hypotension, bradycardia, arrhythmia risk

Fosphenytoin preferred where available (less local toxicity, faster infusion)

Sodium Valproate IV

Dose: 40 mg/kg IV over 10 min (max 3000mg)

Avoid in pregnancy, liver disease. Effective for generalised and focal SE.

Lacosamide IV

Dose: 200–400mg IV over 15 min

Emerging option; cardiac monitoring for PR prolongation. Used in some GCC tertiary centres.

🔴

Refractory SE requires ICU admission, intubation, and general anaesthesia. Call ITU/anaesthetics immediately.

Propofol

1–2 mg/kg IV bolus then 2–10 mg/kg/h infusion. ICU only. Risk of propofol infusion syndrome (PRIS) with prolonged use — monitor triglycerides, lactic acidosis.

Midazolam Infusion

0.2 mg/kg bolus then 0.05–2 mg/kg/h infusion. Widely available in GCC ICUs. Accumulates with prolonged use.

Thiopental / Pentobarbital

Used for super-refractory SE. Requires EEG monitoring for burst-suppression. Significant haemodynamic side-effects.

Continuous EEG (cEEG) monitoring required in RSE

Target: burst-suppression pattern. Neurologist/epileptologist must be involved. Consider treatable causes: autoimmune encephalitis (anti-NMDA receptor), NCSE (non-convulsive SE).

👆

Airway Management During Seizure

  1. Do NOT put anything in the mouth — do not force airways or objects between teeth during convulsion
  2. Recovery position as soon as tonic-clonic phase ends — left lateral decubitus
  3. High-flow O2 15 L/min via non-rebreathe mask
  4. Suction secretions once safe — soft suction catheter only
  5. Guedel airway only if mouth relaxed (post-ictally) and gag reflex absent
  6. Prepare BVM and intubation equipment if seizure prolonged or airway compromised
  7. SpO2 and EtCO2 monitoring continuously

Common AEDs — Nursing Considerations

AEDIndicationKey Nursing PointsMonitoringTeratogenicity
Levetiracetam
(Keppra)
Focal, generalised, adjunct Monitor for behavioural changes — irritability, aggression, depression (5–10%). Ensure renal dose adjustment. IV and oral bioequivalent. Renal function (dose-adjusted). Routine levels not required. Low — Category C. Often preferred in pregnancy.
Sodium Valproate
(Epilim)
Generalised epilepsies (first choice), focal, absence, myoclonic Take with food — GI side-effects. Monitor weight gain, hair thinning. Pancreatitis risk. Liver function monitoring. MHRA/GCC guidance on use in women of child-bearing age. LFTs (first 6 months), FBC, ammonia if encephalopathic. Drug levels useful. HIGH — Category D. Neural tube defects (spina bifida), autism spectrum disorder, developmental delay. Avoid in women of child-bearing age unless no alternative.
Lamotrigine
(Lamictal)
Focal, generalised, absence, Lennox-Gastaut Slow titration essential to reduce SJS risk. Report any rash immediately — risk of Stevens-Johnson Syndrome (SJS) especially with rapid dose escalation. Levels increase in pregnancy. Clinical monitoring for rash. Levels in pregnancy (requires dose increase). Moderate — Category C. Preferred AED in pregnancy among available options. May increase risk of oral cleft at high doses.
Carbamazepine
(Tegretol)
Focal epilepsy, trigeminal neuralgia Enzyme inducer — multiple drug interactions (contraceptives, warfarin, phenytoin). Hyponatraemia monitoring. HLA-B*1502 testing before starting in patients of Han Chinese/Thai origin (SJS risk). FBC, LFTs, Na at baseline and 6 months. Drug levels useful (trough). ECG in elderly. HIGH — Neural tube defects. Avoid in pregnancy if possible.
Phenytoin
(Dilantin)
Focal, tonic-clonic, IV acute SE Narrow therapeutic index — toxicity at levels just above therapeutic. Signs: nystagmus, ataxia, diplopia, confusion. IV: monitor ECG, BP. Gingival hyperplasia with chronic use. Zero-order kinetics — small dose increase can cause large rise in levels. Drug levels: therapeutic 10–20 mg/L (total); 1–2 mg/L (free). ECG during IV administration. LFTs, FBC. HIGH — Category D. Fetal hydantoin syndrome. Avoid in pregnancy.
⚠️

Sodium Valproate — GCC Safeguarding Context

🔴

GCC-specific concern: High birth rates across GCC (UAE TFR ~1.4, Saudi Arabia ~2.4, Qatar ~1.8) mean valproate prescribing in women of child-bearing age carries substantial population-level teratogenic risk.

  • Valproate Pregnancy Prevention Programme (VPPP) mandatory — UK/EU model increasingly adopted
  • Female patients must receive annual risk acknowledgement documentation
  • Discuss effective contraception at every consultation
  • Folic acid 5mg daily if pregnancy anticipated
  • Nurse's role: document counselling, ensure patient understanding, escalate non-compliance concerns
  • If patient becomes pregnant on valproate: do NOT stop suddenly — urgent neurology referral same day
🌎

AED Compliance & Patient Counselling

Key Messages — Never Stop Suddenly
  • Stopping AED suddenly risks breakthrough seizures and status epilepticus
  • If a dose is missed: take as soon as remembered; do not double-dose next time
  • Alcohol lowers seizure threshold — discuss harm reduction
  • Sleep deprivation is a major trigger — sleep hygiene counselling
  • Reporting: any change in seizure frequency, side-effects, new medications
Driving Restrictions (see Tab 4 for full GCC details)

Must be seizure-free for the legally required period before driving. Patient is legally obliged to notify licensing authority. Nurse documents this education in notes.

Ramadan Fasting — AED Timing Adjustments

Consult neurologist/pharmacist before Ramadan. Once-daily AEDs: take at Iftar or Suhoor. Twice-daily: split between Iftar and Suhoor. Avoid long fasting gaps with phenytoin (erratic levels). Ensure hydration — hyponatraemia triggers seizures. Levetiracetam and lamotrigine are most flexible for Ramadan scheduling.

🔫

Phenytoin — Narrow Therapeutic Index Management

Therapeutic Range
Total phenytoin10–20 mg/L
Free phenytoin1–2 mg/L
Trough sampling timeJust before next dose
Toxicity Signs (levels >20 mg/L)
  • Nystagmus (>20 mg/L)
  • Ataxia, diplopia (>30 mg/L)
  • Dysarthria, confusion (>40 mg/L)
  • Seizures paradoxically worsen at toxic levels
  • Hypotension, bradycardia during IV infusion
Special Situations Affecting Levels
  • Hypoalbuminaemia — free fraction increases (use corrected level formula)
  • Renal failure — use free level monitoring
  • Pregnancy — levels fall (volume of distribution increases)
  • Enzyme inducers (carbamazepine, rifampicin) reduce levels
  • Enzyme inhibitors (fluconazole, omeprazole) increase levels
🏥

Hospital Seizure Precautions Checklist

For ALL patients at risk of seizure:
📚

Falls Risk in Epilepsy

Epilepsy patients have a 2–6x increased risk of falls and fractures. Atonic and tonic-clonic seizures carry the highest falls risk.

Falls Risk Factors to Document:
  • Seizure type — atonic seizures = highest sudden fall risk
  • Seizure frequency — uncontrolled epilepsy = higher risk
  • AED side-effects: dizziness, ataxia (phenytoin, carbamazepine)
  • Post-ictal confusion — disorientation increases fall risk
  • Night-time seizures — especially in elderly
  • SUDEP risk factors — monitoring during sleep
Protective Measures:
  • Helmet use for high-fall-risk patients (atonic seizures)
  • Ground-level sleeping arrangements at home
  • Seizure detection devices/alarms
  • Physiotherapy referral for balance rehabilitation
🌞

Epilepsy Safety Advice — Patient & Family Education

Water Safety
  • Never swim alone — always with a seizure-aware companion
  • Shallow baths only — fill to minimum; do not lock bathroom door
  • Shower preferred over bath for epilepsy patients
  • Jacuzzi/hot tub: avoid (vasodilatory trigger + drowning risk)
  • Inform lifeguard of epilepsy diagnosis
Kitchen & Cooking
  • Use back hobs on cooker — prevents pan dragging
  • Microwave preferred over gas/electric hob
  • Kettle tipper device; use small amounts of boiling water
  • Sit to cook when possible; use a stool at kitchen counter
  • Non-slip mats; avoid sharp implements when alone
Heights & Machinery
  • Avoid working at heights (ladders, scaffolding, roofs)
  • No operating heavy machinery or power tools when uncontrolled
  • Stairs: use handrail; carpeted stairs preferred
  • Sports: contact sports, cycling — helmet always; swimming rules above
  • Occupation risk assessment required — document and refer

Vagal Nerve Stimulator (VNS) — Nursing Considerations

VNS is an adjunctive neuromodulation therapy for drug-resistant epilepsy. A subcutaneous device implanted in the left chest wall delivers intermittent electrical pulses to the left vagus nerve.

Nursing Points:
  • Device settings programmed externally — a magnet swiped over device activates an on-demand stimulation to abort a seizure
  • Teach patient and carers magnet use — abortive therapy during aura or onset
  • Voice hoarseness, cough, and throat discomfort are common side-effects (vagus nerve stimulation)
  • MRI: VNS patients require specific MRI protocols — notify radiology before any scan
  • Diathermy: avoid in surgical patients — must inform surgical team
  • Document VNS presence clearly in nursing notes and medication chart
  • No chest compressions directly over device — use only if life-threatening emergency
💊

Rescue Medication Education for Carers

Buccal Midazolam (first choice in community)

Adult dose: 10mg; Child dose: by weight (0.3 mg/kg, max 10mg)

Route: Squirt between gum and cheek using applicator syringe; half each side

When to give: Seizure lasting >5 minutes OR third seizure in 24 hours without recovery

Rectal Diazepam (alternative)

Adult dose: 10–20mg; Child: 0.5 mg/kg

Less socially acceptable in GCC cultural context — buccal midazolam is strongly preferred for community and school settings

Call 999/emergency if:
  • Seizure does not stop 5 minutes after rescue medication given
  • Person does not wake up after seizure stops
  • Another seizure occurs shortly after
  • Injury has occurred during seizure
🔎

Seizure Triggers — Identification & Avoidance

Lifestyle Triggers
Sleep deprivation Alcohol consumption Drug misuse Missed AED doses Emotional stress Extreme fatigue
Environmental Triggers
Flashing lights (photosensitivity ~3%) Screen flickering Fever / illness Hyperventilation Menstrual cycle (catamenial epilepsy) Extreme heat (GCC context — vasodilation, dehydration)
GCC-Specific Considerations
  • Ramadan fasting — disrupted sleep patterns, dehydration, electrolyte changes
  • Extreme summer heat (40–50°C) — dehydration trigger
  • High incidence of genetic/structural epilepsies related to consanguinity
  • Traditional herbal remedies (may interact with AEDs)
  • Encourage seizure diary — Arabic language apps available
👶

Epilepsy in Pregnancy

🔴

Women with epilepsy (WWE) have higher risk of SUDEP, complications of pregnancy, and AED teratogenicity. Requires specialist multidisciplinary management from pre-conception.

  • Folic acid 5mg daily: Start pre-conception; continue through first trimester (high-dose due to AED folate depletion)
  • AED choice: Avoid valproate; lamotrigine or levetiracetam preferred; all AEDs carry some risk
  • Seizure risk in pregnancy: Increases due to altered drug metabolism, sleep deprivation, stress; do NOT stop AEDs without specialist review
  • Lamotrigine levels fall in pregnancy — may require dose increases up to 100%; monitor levels monthly
  • SUDEP risk increases if seizures uncontrolled during pregnancy
  • Vitamin K 10mg orally from 36 weeks (AED enzyme inducers reduce neonatal vitamin K)
  • Breastfeeding: generally safe with most AEDs; valproate and lamotrigine transferred in low amounts
👪

Paediatric Epilepsy

Febrile Seizures vs Epilepsy
FeatureFebrile SeizureEpilepsy
TriggerFever (>38°C) — usually viralNot fever-related (or afebrile)
Age6 months – 6 yearsAny age
Recurrence30% risk of further febrile seizure; <5% develop epilepsyBy definition recurrent unprovoked
EEGUsually normalTypically abnormal
TreatmentManage fever; rectal diazepam rescue; no long-term AEDAED after second unprovoked seizure
Ketogenic Diet Nursing
  • High-fat, low-carbohydrate diet for drug-resistant paediatric epilepsy
  • Nursing: monitor weight, urine ketones (aim 3–4+ ketones), blood glucose, lipid profile
  • Constipation, kidney stones, and dyslipidaemia are common side-effects
  • All medications must be sugar-free — check every drug formulation
  • Families require extensive dietitian support; cultural adaptation for GCC Arabic diets needed
👴

Elderly Epilepsy

New-onset epilepsy in the elderly (>65 years) is the most common age group for new diagnosis. Stroke is the most common aetiology (30%).

Polypharmacy Drug Interactions — Key AED Risks:
  • Carbamazepine: interacts with warfarin (INR reduced), statins, antihypertensives
  • Phenytoin: interacts with warfarin, NSAIDs, proton pump inhibitors, antibiotics
  • Valproate: increases free warfarin; inhibits lamotrigine metabolism
  • Levetiracetam: minimal interactions — often preferred in elderly
  • Lamotrigine: minimal interactions — also suitable in elderly
Geriatric Considerations:
  • Reduced renal clearance — levetiracetam dose adjustment required
  • Increased fall risk with all AEDs — assess gait and balance
  • Hyponatraemia from carbamazepine especially in frail/cardiac patients
  • Cognitive side-effects more pronounced — topiramate and phenobarbitone should be avoided
🧠

Post-Traumatic Epilepsy (PTE)

Epilepsy developing after traumatic brain injury (TBI). Risk increases with severity of TBI, intracranial haemorrhage, depressed skull fractures, and penetrating head injuries.

Classification:
Immediate (<24h)Impact seizure — does not predict PTE
Early (1–7 days)Treat with AED prophylaxis (7 days); levetiracetam preferred
Late (>7 days)True PTE — long-term AED therapy required
GCC Context — RTAs & TBI:

GCC has among the world's highest road traffic accident (RTA) rates. Saudi Arabia, UAE, and Oman have significant TBI burdens. Nurses in trauma/neuro ICUs must be alert to early post-traumatic seizures and prophylaxis protocols.

🌞

Epilepsy in the GCC — Consanguinity & Genetic Syndromes

Consanguinity-Related Epilepsy

Consanguineous marriage rates in GCC remain among the highest globally (25–55% in Saudi Arabia, Qatar, UAE). This increases the prevalence of autosomal recessive epilepsy syndromes:

  • Dravet Syndrome (SCN1A mutations) — severe myoclonic epilepsy of infancy
  • Lennox-Gastaut Syndrome — multiple seizure types, cognitive impairment
  • Progressive myoclonic epilepsies (Lafora disease, Unverricht-Lundborg)
  • Metabolic epilepsies — pyridoxine-dependent, glucose transporter deficiency
  • Tuberous Sclerosis Complex (TSC)
Family Education — GCC Considerations
  • Genetic counselling referral for families with epilepsy syndrome diagnosis
  • Explain recessive inheritance risk to parents sensitively
  • Extended family often involved in care decisions — include them in education
  • Arabic language materials essential for low-literacy families
  • Religious framing: emphasise this is a medical condition, not spiritual punishment
  • Epilepsy stigma remains significant in GCC — address directly with patient and family
ⓘ️

In GCC: genetic epilepsy syndromes are disproportionately common. Nursing assessment should include family history of seizures, consanguinity, and developmental delay in siblings.

💔

SUDEP — Sudden Unexpected Death in Epilepsy

🔴

SUDEP occurs in approximately 1 in 1000 adults with epilepsy per year. It is the leading cause of death in people with uncontrolled epilepsy. Risk is highest in young adults with uncontrolled tonic-clonic seizures, especially during sleep.

Risk Factors for SUDEP
  • Frequent generalised tonic-clonic seizures (highest risk)
  • Nocturnal seizures — sleeping alone
  • Male sex; young adult age
  • Drug-resistant epilepsy; poor AED compliance
  • Prone sleeping position during/after seizure
  • Alcohol use
Protective Factors
  • Seizure freedom (especially GTCS)
  • AED compliance; optimal treatment
  • Not sleeping alone — nocturnal supervision
  • Seizure detection devices and alarms
  • Breathing monitor / seizure alarm mattress
Nursing Role — Counselling
  • SUDEP counselling is part of every epilepsy nurse consultation
  • Use SUDEP Action resources; document counselling given
  • Sensitive framing: focus on risk reduction, not fatalism
  • Advise on safe sleeping position (lateral/supine); avoid prone
  • GCC context: living in family home = natural supervision — discuss openly as protective

DHA / DOH / SCFHS / QCHP High-Yield Questions

Q1. A patient has been seizing for 8 minutes with IV access. Which is the MOST appropriate first drug to give?
A: Lorazepam 4mg IV over 2 minutes. This is the Stage 2 drug of choice with IV access. Buccal midazolam is the alternative without IV access.
Q2. A nurse observes a patient having a generalised tonic-clonic seizure. What is the FIRST nursing action?
A: Note the exact start time and ensure patient safety (remove hazards, protect head, lateral position if possible). Do NOT put anything in the mouth. Call for help if seizure continues beyond 5 minutes.
Q3. Which AED is CONTRAINDICATED in absence seizures and may worsen them?
A: Carbamazepine (and also phenytoin and vigabatrin). These are sodium-channel drugs that can exacerbate absence seizures. Ethosuximide is the first-line treatment for pure absence epilepsy.
Q4. A woman of child-bearing age is on sodium valproate. What is the nurse's primary responsibility?
A: Ensure she has received counselling about teratogenic risks, document the counselling, confirm she is on effective contraception, and ensure she is enrolled in the Valproate Pregnancy Prevention Programme (VPPP). Annual risk acknowledgement form must be completed.
Q5. What is the definition of status epilepticus?
A: A seizure lasting more than 5 minutes, OR two or more discrete seizures without full recovery of consciousness between them. The operational definition for treatment purposes is 5 minutes (NICE/ILAE current guidelines).
Q6. After a generalised tonic-clonic seizure, a patient has right-sided arm weakness. What is this called and how long does it last?
A: Todd's paresis (Todd's paralysis). Focal neurological weakness after a focal or generalised seizure, lasting minutes to hours (rarely up to 48h). It is a post-ictal phenomenon and resolves spontaneously — but must be differentiated from acute stroke (brain imaging needed if prolonged).
Q7. Which AED has zero-order kinetics and a narrow therapeutic index requiring serum level monitoring?
A: Phenytoin. Zero-order kinetics mean a small dose increase can cause a disproportionately large rise in serum level, risking toxicity. Therapeutic range: 10–20 mg/L total. Signs of toxicity: nystagmus, ataxia, diplopia, confusion.
Q8. A patient with refractory epilepsy has a VNS device. What must the nurse alert before any MRI scan?
A: Alert the radiology team and MRI radiographer about the VNS device. VNS requires specific MRI-conditional protocols. Standard MRI may be contraindicated. The device details (model, lead configuration) must be checked before scanning.
