History Taking of Stroke Patient

The most critical piece of information is the exact time of symptom onset—defined as when the patient was last known to be at baseline or symptom-free—as this determines eligibility for time-sensitive interventions like thrombolysis and thrombectomy 1.

Time of Onset (Most Critical)

  • Document when the patient was last known to be normal/symptom-free, not when symptoms were discovered
  • For wake-up strokes: time last seen awake and symptom-free before sleep
  • Use creative anchoring: cell phone timestamps, TV program times, bathroom/kitchen visits
  • If symptoms worsened over hours: use time of first symptom
  • If prior TIA completely resolved then new event: reset clock to new symptom onset 1

Symptom Progression and Characteristics

Document the specific pattern:

  • Sudden onset focal deficits (hemiparesis, speech disturbance, visual loss, facial weakness)
  • Progression: stable, worsening, or fluctuating
  • Any preceding transient symptoms that resolved
  • Associated symptoms: headache severity, vomiting, altered consciousness, seizure activity 2, 1

Demographics (Essential Data Points)

  • Age, sex, race/ethnicity, birthplace
  • Education level, occupation, literacy status
  • Handedness
  • Living situation and baseline independence level
  • Primary language 3

Vascular Risk Factors (Systematic Inquiry)

Cardiovascular disease:

  • Myocardial infarction, atrial fibrillation/arrhythmia
  • Heart failure, angina, peripheral artery disease
  • Prior cardiac procedures (CABG, stent, valve surgery, pacemaker) 3

Cerebrovascular history:

  • Prior stroke (ischemic/hemorrhagic), TIA, carotid endarterectomy
  • Any cognitive changes after prior surgeries 3

Metabolic/systemic:

  • Hypertension, diabetes mellitus, hyperlipidemia
  • Hypercoagulable states, DVT, pulmonary embolus, spontaneous abortion
  • Sickle cell disease, renal disease
  • Autoimmune diseases, chronic infections 3

Medications (Complete List Required)

  • All prescription medications (especially anticoagulants, antiplatelets)
  • Over-the-counter preparations
  • Contraceptives, hormone replacement
  • Recent medication changes 3, 2, 3

Social History

  • Tobacco use (current, past, pack-years)
  • Alcohol consumption (quantity, frequency)
  • Illicit drug use (particularly cocaine, amphetamines)
  • Diet patterns, physical activity level
  • Environmental exposures (secondhand smoke, pesticides) 3, 1

Family History (First-Degree Relatives)

  • Stroke (age at event)
  • Vascular disease including MI
  • Dementia
  • Other neurological diseases
  • Age at death for deceased relatives 3

Recent Events (Treatment Contraindications)

Query specifically about:

  • Recent trauma, surgery, hemorrhage
  • Recent myocardial infarction
  • Pregnancy status
  • Active bleeding or coagulopathy symptoms 2, 1

Collateral History Sources

When patient cannot provide history due to aphasia, confusion, or decreased consciousness:

  • Family members, friends, coworkers
  • EMS personnel (bring witnesses with patient)
  • Phone contacts (apartment managers, shop owners)
  • Document informant's relationship, contact duration, reliability 3, 1

Red Flags for Stroke Mimics

Screen for alternative diagnoses:

  • Seizure history or witnessed seizure activity
  • Hypoglycemia (diabetes history, check glucose immediately)
  • Migraine with similar prior episodes
  • Drug toxicity (lithium, phenytoin, carbamazepine)
  • Gradual symptom progression suggesting tumor
  • Fever suggesting infection/abscess 1

Clinical Pitfalls to Avoid

  • Never assume onset time—if unknown, use last-seen-normal time
  • Don't dismiss brief resolved symptoms as irrelevant—document all TIAs
  • Don't overlook atypical presentations in women, younger patients, or minorities
  • Always obtain medication list before considering thrombolysis
  • Document specific contraindications to thrombolysis systematically 2, 1
