I now have sufficient information from the textbooks to give a thorough, structured clinical response. Let me compile it.

Approach to a 45-Year-Old Male with Right-Sided Weakness (Right UL + LL)

Right upper and lower limb weakness on the same side = ipsilateral hemiparesis/hemiplegia - this is an upper motor neuron (UMN) pattern pointing to a lesion in the contralateral (left) cerebral hemisphere or ipsilateral upper cervical cord (C1-C5).

Step 1 - Immediate Assessment (ABC First)

PriorityAction
AirwayEnsure patent; check gag reflex
BreathingPulse oximetry; supplemental O2 if SpO2 < 94%
CirculationIV access x2; cardiac monitor; 12-lead ECG immediately
VitalsBP (both arms), HR, RR, temp, glucose (fingerprick)
TimeRecord exact time of symptom onset - critical for thrombolysis window
Treat as acute stroke until proven otherwise. Activate stroke team immediately if symptom onset is within 24 hours.

Step 2 - Focused History (FAST Protocol + Details)

Ask:

  • Time of onset - exact, or last time known well (LKW)
  • Mode of onset - sudden (stroke, hemorrhage) vs. gradual (tumor, abscess, demyelination)
  • Associated symptoms:
    • Facial drooping, slurred speech, aphasia
    • Visual changes (hemianopia, diplopia)
    • Headache (severe = hemorrhage, SAH)
    • Seizures
    • Fever (abscess, encephalitis)
    • Neck pain (cervical myelopathy, dissection)
    • Trauma
  • Vascular risk factors: HTN, DM, AF, hyperlipidemia, smoking, previous TIA/stroke
  • Drug history: anticoagulants, OCP, recreational drugs (cocaine - can cause stroke)
  • Family history of stroke, clotting disorders

Step 3 - Neurological Examination

Confirm UMN Pattern:

FeatureUMN (Central)LMN (Peripheral)
ToneIncreased (spasticity)Decreased (flaccidity)
PowerReduced (hemiparesis)Reduced
ReflexesBrisk/hyperreflexiaDiminished/absent
Plantar responseExtensor (Babinski +ve)Flexor or absent
WastingAbsent (early)Present
FasciculationsAbsentPresent

Key Localizing Signs:

  • Cortical signs (aphasia, neglect, cortical sensory loss, homonymous hemianopia) → hemisphere lesion
  • Crossed signs (contralateral face palsy + ipsilateral body weakness) → brainstem
  • No facial involvement + sensory level → cervical cord (C1-C5)
  • NIHSS score - perform to quantify deficit and guide thrombolysis decision

Step 4 - Urgent Investigations

Immediate (Within 10-20 minutes):

InvestigationPurpose
Non-contrast CT brainRule out hemorrhage (must be done BEFORE thrombolysis)
Blood glucoseHypoglycemia mimics stroke
CBC, PT/INR, aPTTCoagulopathy, platelet count
Serum electrolytes, creatinineMetabolic cause; renal function for contrast
12-lead ECGAF (cardioembolic source), MI
TroponinConcomitant cardiac ischemia (~3-20% of strokes)

Early (Once Stable):

InvestigationPurpose
MRI brain with DWIMost sensitive for early ischemia, demyelination
CT angiography (CTA) head + neckLarge vessel occlusion for thrombectomy candidacy
2D Echo + cardiac Holter (24-48h)Cardioembolic source
Lipid profile, HbA1cVascular risk factors
Carotid DopplerStenosis/dissection
MRI cervical spineIf no brain lesion found + no facial involvement (cord pathology)

Step 5 - Differential Diagnosis

DiagnosisKey Features
Ischemic stroke (most likely)Sudden onset, vascular risk factors, CT normal early
Hemorrhagic strokeSudden severe headache, vomiting, hypertension
Hypertensive encephalopathyBP > 220/120, encephalopathy, visual changes
TIASymptoms resolved < 24h (but still admit urgently)
Brain tumor/metastasisGradual onset, headache, morning vomiting
Brain abscessFever, headache, immunocompromised state
Demyelination (MS)Young, relapsing-remitting, subacute, optic neuritis
Cervical myelopathyNeck pain, no facial involvement, bladder dysfunction
Todd's palsyPost-ictal weakness after seizure
HypoglycemiaBGL < 50 mg/dL, corrects with glucose
CADASIL / vasculitisFamily history, skin/eye findings

Step 6 - Management (Stroke Protocol)

If Acute Ischemic Stroke:

Thrombolysis (IV Alteplase / Tenecteplase):
  • Indicated if onset < 4.5 hours, hemorrhage excluded on CT, no contraindications
  • Alteplase: 0.9 mg/kg IV (max 90 mg); 10% as bolus, rest over 60 min
  • Admit to Stroke Unit / ICU - reduces mortality and disability
Mechanical Thrombectomy:
  • Consider if large vessel occlusion on CTA (MCA, ICA, basilar)
  • Window: up to 24 hours in selected patients
General measures:
  • Keep SBP 160-220 mmHg in acute phase (do NOT aggressively lower BP unless using thrombolytics, where target < 185/110)
  • Maintain SpO2 > 94%
  • Maintain normoglycemia (target 140-180 mg/dL); avoid hypoglycemia
  • Keep head of bed ≥ 30 degrees
  • NPO until formal swallowing assessment by speech pathology
  • DVT prophylaxis: compression stockings/LMWH once hemorrhage excluded
  • Statin therapy early
  • Antiplatelets (aspirin 300 mg loading) if hemorrhage excluded and NOT a candidate for thrombolysis

Monitor for Complications:

  • Brain edema - peaks 72-120 hours post-stroke; herniation risk in younger patients and large infarcts
  • Aspiration pneumonia - occurs in >10% of unilateral hemisphere strokes
  • Cardiac arrhythmias - continuous cardiac monitoring ≥ 48 hours
  • Urinary retention / infections
  • Pressure sores
  • Depression - common post-stroke

Step 7 - Rehabilitation

Start early mobilization as soon as medically stable:
  • Physiotherapy - gait training, upper limb exercises
  • Occupational therapy - ADL retraining
  • Speech and language therapy - if aphasia/dysarthria/dysphagia
  • Secondary prevention: antihypertensives, statins, antiplatelet or anticoagulation (if AF), lifestyle modification

Summary Flowchart

Right UL + LL weakness
        ↓
Vitals + Glucose + ECG + IV access + Stroke team
        ↓
Non-contrast CT Brain (< 20 min)
        ↓
Hemorrhage?
  YES → Neurosurgery consult, BP control, Reversal of anticoagulation
  NO  → Is onset < 4.5h? → YES → IV Alteplase (if no contraindications)
                         → Large vessel occlusion? → Thrombectomy
        ↓
Admit to Stroke Unit, supportive care, secondary prevention

Key clinical pearl: In any patient presenting with acute hemiparesis, treat as stroke and perform an immediate non-contrast CT brain before any anticoagulant or thrombolytic therapy. Time is brain - every 30 minutes of delay in treating ischemic stroke loses approximately 1.9 million neurons.
