Seizure Classification
Focal Onset
- Aware (simple partial) — consciousness preserved; motor, sensory, autonomic, or psychic features
- Impaired awareness (complex partial) — altered consciousness; automatisms, post-ictal confusion
- Focal to bilateral tonic-clonic — spreads to generalised
Generalised Onset
- Tonic-clonic — loss of consciousness, tonic then clonic phase, urinary incontinence possible
- Absence — brief blank staring (5–30s), no post-ictal phase; 3Hz spike-wave on EEG
- Myoclonic — sudden brief jerks, often morning; juvenile myoclonic epilepsy
- Tonic — sustained muscle stiffening
- Atonic — drop attacks; fall injury risk
Unknown Onset
Epileptic spasms (infantile), tonic-clonic of unknown onset.
Status Epilepticus Protocol
Status Epilepticus = seizure ≥5 min OR ≥2 seizures without recovery. Medical emergency.
- 0–5 min: Airway, O2, IV access, glucose (IV dextrose if BSL <3.5), call for help, 12-lead ECG, bloods (FBC, U&E, Ca, Mg, AED levels, toxicology)
- 5–20 min (1st line): Benzodiazepine — IV lorazepam 0.1 mg/kg (max 4mg) or IV diazepam 10–20 mg. Repeat once after 5 min if no effect.
- 20–40 min (2nd line): IV phenytoin 20 mg/kg at ≤50 mg/min (with cardiac monitoring) OR IV levetiracetam 60 mg/kg (max 4.5g) OR IV sodium valproate 40 mg/kg
- 40–60 min (3rd line): IV phenobarbital 15–20 mg/kg at 100 mg/min. Prepare for intubation.
- >60 min (Refractory SE): ICU transfer, intubation, propofol or midazolam or thiopental infusion. EEG monitoring for burst suppression.
Post-Ictal Nursing Care
Immediate (0–30 min)
- Recovery position — maintain airway, avoid restraint
- Time seizure onset AND termination
- O2 via mask, SpO2 monitoring
- IV access if not present
- GCS assessment post-seizure (Todd's paresis may cause focal weakness)
- Protect from injury, remove hazards, padded bed rails
- Suction available — do NOT force airways or tongue blades
Seizure Documentation (Mandatory)
- Date, time, duration
- Preceding aura or warning
- Onset: focal or generalised
- Body parts involved
- Eye deviation (which direction)
- Automatisms, vocalisation
- Urinary/bowel incontinence
- Post-ictal state: confusion, speech, weakness
- Medication given and response
Todd's Paresis: Focal neurological deficit (weakness, aphasia) lasting minutes to hours after a seizure. Resolves spontaneously. Document and monitor — if worsens or persists >24h, investigate for structural lesion.
AED Medication Management
| Drug | Therapeutic Level | Key Interactions / Monitoring | Nursing Points |
|---|
| Phenytoin | 10–20 mg/L (40–80 µmol/L) | Enzyme inducer — reduces warfarin, OCP, statins. Non-linear kinetics (saturation kinetics) | Gingival hyperplasia, ataxia, nystagmus at toxic levels. IV: never in dextrose; ECG monitoring; max 50 mg/min. |
| Carbamazepine | 4–12 mg/L | Strong enzyme inducer. Reduces many drugs. Interacts with macrolides (erythromycin), SSRIs, calcium channel blockers. SIADH. | Diplopia, ataxia, rash. Check FBC, LFTs, Na. Check HLA-B*1502 in Asian patients (Stevens-Johnson risk). |
| Lamotrigine | 2–15 mg/L | Valproate doubles lamotrigine levels — halve dose. Enzyme inducers reduce levels. | Rash in 10% — Stevens-Johnson Syndrome risk. Start low, titrate slowly. Discontinue immediately if rash. |
| Valproate | 50–100 mg/L | Enzyme inhibitor. Increases lamotrigine, phenobarbital levels. Avoid in pregnancy (teratogenic). | Hepatotoxicity, pancreatitis, tremor, weight gain. LFTs, ammonia if encephalopathic. Avoid in women of childbearing age without contraception. |
| Levetiracetam | 10–40 mg/L | Minimal drug interactions. Renally cleared — reduce in CKD. | Behavioural side effects (irritability, aggression). No enzyme induction. |
Vagal Nerve Stimulator (VNS) Nursing
- Implanted device — generator in left chest, lead on left vagus nerve
- Auto-stimulates at set intervals (typically 30s on/5 min off)
- Magnet swipe over device triggers stimulation — can abort seizures; patient/family trained
- Side effects: hoarseness, cough, dyspnoea during stimulation — reassure
- MRI precautions — conditional MRI safe; inform radiographer; use specific protocols
- Do NOT use diathermy over generator site
- Document VNS settings in medication chart
- Battery life 3–8 years; check with neurology if ineffective
SUDEP Education
SUDEP (Sudden Unexpected Death in Epilepsy) — Risk ~1 in 1,000 per year in people with epilepsy; higher with nocturnal tonic-clonic seizures, poor AED compliance, sleeping alone.
Risk Reduction Strategies
- Optimise AED compliance — discuss barriers
- Seizure alarms / monitors at night
- Avoid sleeping alone or prone position
- Avoid seizure triggers: alcohol, sleep deprivation, stress
- Regular neurology follow-up
- Discuss with patient and family sensitively
- Refer to SUDEP Action or local epilepsy support
Monroe-Kellie Doctrine
The skull is a rigid compartment. Total intracranial volume is fixed:
Brain (~80%) + Blood (~10%) + CSF (~10%) = CONSTANT
Increase in any component must be offset by decrease in another. Once compensatory mechanisms exhausted, ICP rises exponentially.
Normal ICP5–15 mmHg
Raised ICP threshold>20 mmHg
Critical ICP>40 mmHg
CPP = MAP − ICPTarget CPP 60–70 mmHg
Cushing's Triad — Late Sign of Herniation
Cushing's Triad = Imminent Brain Herniation
- Hypertension — rising BP (widening pulse pressure)
- Bradycardia — reflex bradycardia
- Irregular respirations — Cheyne-Stokes, ataxic, or apnoea
This is a pre-terminal event. Immediate action: call emergency, hyperventilate, mannitol, neurosurgery.
Herniation Syndromes
- Uncal: Temporal lobe → tentorium. Ipsilateral blown pupil (CN III), contralateral hemiplegia, reduced consciousness
- Central: Bilateral hemispheres downward. Bilateral small pupils → fixed midpoint → blown. Decorticate → decerebrate posturing
- Tonsillar: Cerebellar tonsils → foramen magnum. Sudden apnoea, cardiac arrest. Seen in posterior fossa lesions
ICP Monitoring — EVD & Bolt
External Ventricular Drain (EVD)
- Intraventricular catheter — monitors ICP AND drains CSF
- Zero transducer at foramen of Monro (level of external auditory meatus / tragus)
- Drain height set per neurosurgery order (typically 15–20 cmH2O above zero)
- Document hourly CSF drainage volume and appearance (clear, bloody, turbid)
- Clamp drain before patient repositioning per protocol
- Strict aseptic technique — meningitis/ventriculitis risk
- Signs of infection: fever, neck stiffness, turbid CSF, raised WBC in CSF
ICP Bolt (Parenchymal Monitor)
- Monitors ICP only (no drainage)
- Less infection risk than EVD
- Document ICP waveform morphology (A-waves = plateau waves, ominous)
- Cerebral perfusion pressure (CPP) auto-calculated with invasive arterial BP
ICP Waveform Components
- P1 (percussion wave) — arterial pulsation
- P2 (tidal wave) — brain compliance indicator; P2 > P1 = poor compliance
- P3 (dicrotic wave) — aortic valve closure
Raised ICP — Nursing Management Bundle
Positioning
- HOB 30° elevation
- Head/neck in neutral (no jugular vein compression)
- No hip flexion >90°
- Log-roll for repositioning
Osmotherapy
- Mannitol 0.25–1 g/kg IV over 15–30 min
- Serum osmolality target <320 mOsm/L
- Hypertonic saline 3% or 23.4% — via central line
- Sodium target 145–155 mmol/L
- Monitor serum Na, osmolality, renal function
Avoid / Treat
- Avoid hyperthermia — target normothermia (paracetamol, cooling)
- Avoid hypoxia — SpO2 ≥94%
- Avoid hypotension — MAP ≥80 mmHg
- Avoid hyponatraemia
- Avoid coughing/suctioning surges — premedicate
- Sedate appropriately — reduces cerebral metabolic demand
Hyperventilation as Bridge Therapy: Target PaCO2 30–35 mmHg causes cerebral vasoconstriction, reducing CBV and ICP within minutes. Use ONLY as temporary bridge to definitive treatment (surgery/osmotherapy). Prolonged use causes ischaemia.
Multiple Sclerosis — Types & Relapse Management
| Type | Pattern | Notes |
|---|
| RRMS | Relapsing-Remitting | Most common (85%). Discrete relapses with full or partial recovery. Most patients start here. |
| SPMS | Secondary Progressive | Evolves from RRMS. Gradual worsening with or without relapses. Disability accumulates. |
| PPMS | Primary Progressive | Progressive from onset (~15%). No distinct relapses. Ocrelizumab approved for active PPMS. |
Relapse Management
IV Methylprednisolone 1g/day for 3–5 days — shortens relapse duration (does not change long-term disability). Nursing: monitor glucose, BP, mood, sleep. GI protection with PPI. Do not abruptly stop.
Common Relapse Symptoms
- Optic neuritis — unilateral painful vision loss, colour desaturation
- Transverse myelitis — bilateral leg weakness, sensory level, bladder dysfunction
- Internuclear ophthalmoplegia — horizontal diplopia, nystagmus
- Uhthoff's phenomenon — neurological symptoms worsen with heat/fever (not true relapse)
DMT Monitoring Requirements
| Drug | Route | Monitoring |
|---|
Natalizumab
(Tysabri) | IV 4-weekly | Monthly JC virus antibody index (PML risk). LFTs. Rebound syndrome if stopped abruptly. Alert for new neuro symptoms (PML: progressive multifocal leukoencephalopathy). |
Ocrelizumab
(Ocrevus) | IV 6-monthly | FBC, immunoglobulins. Infusion reactions — premedicate with methylprednisolone + antihistamine. Hepatitis B screen before start. PML risk (lower than natalizumab). COVID-19 vaccine before initiation. |
Alemtuzumab
(Lemtrada) | IV annual ×2 courses | Monthly bloods for 4 years: FBC, creatinine, urinalysis (autoimmune nephropathy), TFTs (thyroid autoimmunity most common). Immune thrombocytopaenia (ITP) — report bruising/petechiae. |
Fingolimod
(Gilenya) | Oral daily | First dose 6h cardiac monitoring (bradycardia/AV block). Ophthalmology at 3–4 months (macular oedema). LFTs, VZV serology before start. |
MS Symptom Management
Fatigue
- Most disabling symptom. Separate from sleep disorders, depression, medication side effects
- Energy conservation techniques: pacing, prioritisation
- Avoid overheating (cooling vests useful in GCC climate)
- Amantadine or modafinil may be prescribed
Bladder Dysfunction
- Overactive bladder (urgency/frequency) → anticholinergics (oxybutynin, solifenacin)
- Urinary retention → clean intermittent self-catheterisation (CISC)
- Teach CISC technique, maintain diary, UTI prevention
- Avoid caffeine, evening fluid restriction
Parkinson's Disease Nursing
Pathology
Loss of dopaminergic neurons in substantia nigra. Lewy body (alpha-synuclein) accumulation. Cardinal features: TRAP — Tremor (resting), Rigidity, Akinesia/bradykinesia, Postural instability.
Dopaminergic Medications
| Drug | Nursing Points |
|---|
| Levodopa/Carbidopa | Give with meals to reduce nausea but high-protein meals reduce absorption. Never miss dose — can cause neuroleptic malignant-like syndrome. Document "ON/OFF" periods. |
| Dopamine agonists | Impulse control disorders (gambling, hypersexuality). Leg oedema. Hallucinations in elderly. |
| MAO-B inhibitors | Avoid tyramine-rich foods (cheese, wine). Drug interactions with SSRIs/SNRIs (serotonin syndrome). |
OFF Periods: Wearing-off = end-of-dose effect. Document symptom timing relative to doses. Consider modified-release preparations, COMT inhibitors, or apomorphine infusion.
DBS (Deep Brain Stimulation) Nursing
- Implanted electrodes in subthalamic nucleus or globus pallidus
- External programmer for adjustments
- MRI conditional — check device specifics; inform MRI team
- Battery check at clinic visits (life 3–5 years or rechargeable)
- Diathermy/electrocautery CONTRAINDICATED
Motor Neurone Disease (MND/ALS)
Overview
Progressive degeneration of upper and lower motor neurons. Affects speech, swallowing, limb function, and breathing. Cognitive involvement in ~50% (FTD-MND spectrum).
Respiratory Support Pathway
- Monitor FVC (forced vital capacity) 3-monthly
- FVC <50% OR symptomatic orthopnoea → initiate NIV (BiPAP)
- NIV nursing: mask fitting, humidification, compliance monitoring, pressure areas
- FVC <30% or bulbar failure → discuss invasive ventilation vs palliative care (patient choice)
- Cough assist device for secretion clearance
- Advance care planning — document early (while capacity retained)
PEG Tube in MND
- Insert before FVC <50% — anaesthetic risk increases below this
- Ideally when patient still ambulatory (safer anaesthetic)
- PEG vs RIG (radiologically inserted gastrostomy) — RIG preferred if FVC very low
- Nursing: stoma care, feed rate, position at 30–45° during feeding, flush protocol
- Oral care continues for comfort even if NBM
- Monitor for aspiration even with PEG (saliva aspiration risk remains)
Riluzole — only approved neuroprotective agent. Modest survival benefit (2–3 months). Monitor LFTs monthly × 3 months, then quarterly.
Consanguinity & Inherited Neurological Conditions in GCC
Consanguinity prevalence in GCC: 25–60% of marriages are consanguineous (first/second cousins), significantly elevating rates of autosomal recessive neurological conditions.
| Condition | Inheritance | Neurological Features | GCC Nursing Considerations |
|---|
| Spinal Muscular Atrophy (SMA) | AR — SMN1 gene | Progressive proximal muscle weakness, respiratory failure (SMA type 1 most severe — infantile), absent reflexes | Nusinersen (intrathecal), onasemnogene (gene therapy). Respiratory support, physiotherapy, nutrition. Newborn screening programmes expanding in GCC. |
| Wilson's Disease | AR — ATP7B gene | Dysarthria, tremor, dyskinesia, psychiatric symptoms, Kayser-Fleischer rings | Higher prevalence in Gulf Arab and Lebanese populations. Monitor copper, caeruloplasmin. Penicillamine or trientine. Dietary copper restriction. Liver function critical. |
| Batten Disease (NCL) | AR — CLN genes | Progressive vision loss, seizures, cognitive decline, motor deterioration in children | Rare but clusters in consanguineous families. Supportive care, AED management, palliative approach. Cerliponase alfa (CLN2) available in some GCC centres. |
| Familial Mediterranean Fever (FMF) | AR — MEFV gene | Aseptic meningitis episodes, cerebral amyloidosis (rare), headache | Common in Arab, Turkish, Armenian populations. Colchicine is mainstay. Neurological involvement suggests amyloid or vasculitis workup. |
MERS-CoV Neurological Manifestations

- Avoid shivering (increases heat production) — benzodiazepines if needed
- Neuro obs every 15 min during cooling phase
- Treat seizures per status epilepticus protocol
- Monitor for rhabdomyolysis (dark urine, CK), DIC, AKI
- MRI brain at 24–72h if persistent neuro deficit
Hajj Pilgrimage — Neurological Emergencies
Hajj context: Up to 3 million pilgrims annually. Peak temperatures 40–50°C. Mass gathering medicine. GCC nurses (Saudi Arabia, UAE, Qatar) may be deployed to field hospitals in Mecca/Medina.
Heat Stroke at Hajj
- Leading cause of neurological emergencies — particularly older pilgrims
- Rapid identification: confusion + high temperature during outdoor rituals (Tawaf, Sa'i, stoning)
- Field cooling stations: water sprays + fans
- Triage and transfer to field hospital within 30 minutes
- IV fluid resuscitation — avoid hyperhydration (hyponatraemia risk)
Hajj Stroke Unit Deployment
- Ministry of Health Saudi Arabia deploys mobile stroke units during Hajj season
- tPA available at Ajyad Emergency Hospital, Mecca
- Language challenge — multilingual nursing teams essential
Meningococcal Meningitis
- Mass gathering high risk — quadrivalent ACWY vaccine mandatory for Hajj visa
- Features: fever, neck stiffness, photophobia, non-blanching rash (purpura)
- Do NOT delay antibiotics for LP if meningococcal meningitis suspected
- IV ceftriaxone 2g immediately, dexamethasone 0.15 mg/kg QDS × 4 days
- Isolation protocol: droplet precautions 24h post-antibiotics
- Contact tracing and chemoprophylaxis (ciprofloxacin/rifampicin)
Other Hajj Neurological Emergencies
- Hyponatraemia (excessive water intake) — seizures, confusion
- Hypoglycaemia in diabetic pilgrims fasting
- Cerebral venous thrombosis — dehydration risk factor
- Crush injury neurological trauma (Mina stampede risk)

Familial Dysautonomia & Autonomic Disorders in GCC Arab Populations
Familial Dysautonomia (Riley-Day Syndrome)
Ultra-rare AR disorder (IKBKAP gene). Classic form in Ashkenazi Jews; dysautonomia spectrum conditions exist in consanguineous Arab families with different genetic mutations.
Clinical Features of Autonomic Dysfunction
- Orthostatic hypotension — falls risk, syncope
- Anhidrosis (inability to sweat) — heat stroke risk particularly relevant in GCC climate
- Cardiac dysrhythmias
- Bladder dysfunction
- Gastroparesis
- Temperature dysregulation
GCC-Specific Autonomic Nursing
- Orthostatic BP measurement (lying → standing → 1 min → 3 min)
- Drop >20 mmHg systolic or >10 mmHg diastolic = orthostatic hypotension
- Compression stockings, head-up tilt-table, fludrocortisone
- Patient education: rise slowly, avoid prolonged standing, avoid heat
- Hydration monitoring — increased insensible losses in GCC heat
- Cooling strategies for anhidrotic patients
- Diabetes-related autonomic neuropathy common in GCC (high T2DM prevalence)
Diabetes Prevalence: GCC has one of the world's highest T2DM rates (15–25%). Diabetic peripheral and autonomic neuropathy represent a major neurology nursing burden in all GCC countries.
