Stroke and TIA
Questionnaire/history:
TIA:
- Sudden onset, focal neurological deficit which has completely resolved within 24 hours (mostly within 1 h) of onset and cannot be explained by another condition such as hypoglycaemia?
- Focal neurological deficits:
- Unilateral weakness or sensory loss?
- Dysphasia?
- Ataxia, vertigo or loss of balance?
- Syncope?
- Sudden transient loss of vision in one eye (amaurosis fugax), diplopia, or homonymous hemianopia?
- Cranial nerve defects
Stroke:- Sudden onset, focal neurological deficit which is ongoing or has persisted for longer than 24 hours and cannot be explained by another condition such as hypoglycaemia - Clinical features vary depending on causative mechanism and the area of the brain affected:
- Confusion, altered level of consciousness and coma?
- Headache?
- Insidious onset and gradually increasing intensity (?intracranial haemorrhage)?
- Sudden, severe headache which may be associated with neck stiffness and sentinel headache(s) in the preceding weeks (subarachnoid haemorrhage)?
- Unilateral weakness or paralysis in the face, arm, or leg?
- Sensory loss — paraesthesia or numbness?
- Ataxia?
- Dysphasia?
- Dysarthria?
- Visual disturbance — homonymous hemianopia, diplopia?
- Gaze paresis — this is often horizontal and unidirectional?
- Photophobia?
- Dizziness, vertigo, or loss of balance (isolated dizziness is not usually a symptom of TIA)?
- Nausea and/or vomiting?
- Cranial nerve deficits such as unilateral tongue weakness or Horner’s syndrome (miosis, ptosis, and facial anhidrosis)?
- Difficulty with fine motor coordination and gait?
- Neck or facial pain (associated with arterial dissection)? - Acute, persistent, continuous vertigo or dizziness with nystagmus, nausea or vomiting, head motion intolerance and new gait unsteadiness (?acute vestibular syndrome) (?posterior circulation strokes)?
