⚠
Last-Seen-Well Time is Critical: If patient wakes from sleep with symptoms, use time last seen well (bedtime), not wake-up time. Document precisely — it determines thrombolysis eligibility.
Stroke Types
Ischaemic — 85%
Large Artery Atherosclerosis: MCA/ICA stenosis, sudden focal deficit, often severe
Cardioembolic (AF/cardiac): Abrupt onset, cortical signs, AF history
Small Vessel / Lacunar: Subcortical, pure motor/sensory, no cortical features
Immigrant workforce: Access to care delayed — language barriers, fear of documentation issues
Stroke vs Stroke Mimic — Differential Diagnosis
Mimic
Key Feature
Distinguishing Test/Clue
Action
Hypoglycaemia#1 Mimic
Focal deficit, confusion, reduced consciousness
BGL <3.5 mmol/L — always check first
IV dextrose — resolves rapidly
Complicated Migraine
Aura with focal neuro signs — visual, sensory
Prior migraine history, young female, headache-dominant
MRI brain if uncertain
Todd's Paresis
Post-ictal weakness after seizure
Witness account of seizure, gradual improvement
EEG, MRI; do not thrombolyse
Multiple Sclerosis
Relapse with new focal deficit
Known MS, MRI white matter lesions, younger patient
MRI brain with DWI
Brain Tumour
Progressive, headache, papilloedema
CT/MRI mass lesion, subacute onset
CT contrast / neurosurgery
Hypertensive Encephalopathy
Diffuse neurological + BP >200
Bilateral/diffuse — not focal; PRES on MRI
Controlled BP reduction
Functional Neurological Disorder
Inconsistency on exam, Hoover's sign
Normal imaging, psychological stressor
Neurology review, no tPA

Door-to-Needle (tPA) — TARGET
ℹ
Door-to-Needle <60 min is the international benchmark. Every minute of delay = ~1.9 million neurons lost. Nurses must NOT delay for consent paperwork, baseline bloods alone, or waiting for family — initiate code stroke immediately on clinical suspicion.
NIHSS — NIH Stroke Scale (0–42)
ℹ
NIHSS is the gold-standard stroke severity tool. 11 items assess consciousness, gaze, vision, facial movement, arm/leg strength, coordination, sensation, language, speech, and neglect. Score 0 = no stroke deficit; >20 = severe.

CT Brain Interpretation Basics for Nurses
Hyperdense MCA sign: Bright white dot/line in MCA territory on non-contrast CT = fresh thrombus = early ischaemic stroke — tPA may be indicated
Hyperdensity (bright white): Blood — haemorrhage → STOP, do not give tPA
Hypodensity (dark grey): Established infarct — if >1/3 MCA territory = no tPA
Normal CT: Does not exclude ischaemic stroke — early ischaemia CT-negative for first 6 hrs
ASPECTS score: CT scoring 0–10 for MCA ischaemia extent — ASPECTS ≤6 = extensive infarct, poor outcome with tPA/EVT
✕
Nurses do not interpret CT scans independently. Report immediately to physician and document CT time and result communication time.
Blood Pressure Management — Acute Stroke
Ischaemic Stroke (Before tPA)
⚠
Permissive Hypertension: Allow BP up to 220/120 mmHg. Penumbra relies on elevated BP for collateral perfusion. Do NOT aggressively lower BP unless >220/120 or EVT planned.
Rare but serious complication after rapid recanalization of a previously occluded vessel — especially after carotid endarterectomy or successful EVT.
Clinical Features
Severe ipsilateral headache (pulsatile)
Hypertension — often refractory
Focal seizures
Cerebral oedema on imaging (PRES-like)
Intracerebral haemorrhage (severe cases)
Nursing Response
Urgent CT brain
Aggressive BP management — target SBP <130 mmHg
Seizure precautions, benzodiazepines ready
Notify neurosurgery and neurology immediately
FAST Bundle — Stroke Unit Nursing Care
F
Fever Management
Temperature >37.5°C → paracetamol 1g IV/PO
Identify source: aspiration pneumonia, UTI, DVT
Avoid hyperthermia — worsens neuronal injury
Cooling measures if persistent fever
A
Airway & Oxygen
Supplemental O₂ ONLY if SpO₂ <94%
Hyperoxia is harmful — do not routinely apply O₂
Positioning: lateral recovery if reduced consciousness
Aspiration precautions until swallow screen passed
S
Sugar (Glucose)
Target BGL 4–11 mmol/L
BGL <4: treat hypoglycaemia promptly
BGL >11: insulin per sliding scale protocol
Hourly BGL during insulin infusion
T
Time Metrics
Document: door time, CT time, tPA time, NIHSS time
Report delays to charge nurse and stroke coordinator
Track door-to-needle and door-to-puncture times
Quality improvement — every minute counts
Dysphagia Screening — Critical Priority
🚨
Nothing by mouth (NBM) until swallow screen is PASSED. Oral route is the number one cause of aspiration pneumonia in stroke — a leading cause of early post-stroke death.
Water Swallow Test (3oz/90ml Test)
Patient must be alert and able to follow commands
HOB at 90° (fully upright)
Give 3 oz (90 mL) of water in a cup — patient drinks continuously
Thrombolysis available at tertiary centres; EVT capability expanding; transfer protocols for complex cases
ℹ
Telestroke: Expanding across GCC to reach remote and community hospitals — enables remote NIHSS assessment and tPA decision-making with specialist neurology support.
AF and Cardioembolic Stroke in GCC
AF prevalence: Rising in GCC elderly population — linked to hypertension, obesity, diabetes, and sleep apnoea
Underprescription of anticoagulation: Cultural fear of bleeding and reluctance to take lifelong medication leads to undertreated AF → preventable cardioembolic stroke
DOAC preference: Apixaban, rivaroxaban preferred over warfarin — no INR monitoring, fewer food/drug interactions; culturally more acceptable
Post-stroke AF detection: 72-hour cardiac monitoring minimum; long-term Holter if index event negative
Nurse role: Medication adherence counselling; explain bleeding risk vs stroke prevention; involve family in shared decision
Stroke in Young Adults (25–40 yr) — GCC
Arterial dissection: Carotid or vertebral — trauma, chiropractic manipulation, neck hyperextension — presents with neck pain + stroke
Patent Foramen Ovale (PFO): Paradoxical embolism — closure considered in cryptogenic stroke <60 years (CLOSE trial)
Hypercoagulable states: Factor V Leiden, protein C/S deficiency — more common in consanguineous populations
Substance use: Khat, cannabis, amphetamine — vasospasm and cardioembolism; often undisclosed — ask sensitively
Pregnancy-related: Cerebral venous thrombosis in peri-partum period
Arabic Language Aphasia Assessment
⚠
Most validated aphasia and cognitive tools (NIHSS language component, MoCA, MMSE) are standardised in English. Arabic translations lack full normative validation in GCC populations.
Family involvement: Medication supervision by family member improves GCC adherence significantly
Islamic & Cultural Perspectives on Stroke Disability
Cultural Factors Supporting Recovery
Family-centred care: Large extended family networks provide strong carer support — leverage this for rehabilitation and medication adherence
Community support: Mosque-based support networks; Islamic relief organisations
Positive coping: Tawakkul (reliance on God) can reduce anxiety and depression during recovery
Meaning-making: Illness viewed as test/purification — can motivate perseverance in rehab
Potential Barriers to Recognise
Fatalism (qadar): Misinterpreted as passivity — nurses should explain that seeking treatment is an Islamic duty
Disability stigma: Fear of becoming a burden; shame regarding dependence — affects motivation and disclosure
Rehabilitation engagement: Limited awareness of outpatient neurorehab; public sector capacity insufficient across most GCC states
Gender barriers: Female patients may resist mixed therapy settings; request same-sex therapists when possible
Stroke rehabilitation in GCC: Private sector expensive and inaccessible; public sector has limited outpatient capacity — advocate for inpatient rehab extension when possible
