PHYSICIAN'S CORNER
Motor Weakness, Numbness, Speech Difficulty, Vertigo, Imbalance, Visual Changes, or Cranial Nerves Deficit
1. Sudden onset (less then 1-2 days history)
CT examination of the brain (non contrast) is indicated to rule out Intracerebral hemorrhage. If the CT is normal, follow-up examination may be either CT or MRI. MRI is preferred if available. MRI will be more useful for brain stem or Posterior fossa stroke.
2. Slow onset (weakness or numbness of one of more extremity or cranial nerve deficit developing slowly)
MRI is preferred. Underlying abnormality may be neoplasm either primary or metastatic, Multiple Sclerosis, Subdural hematoma, or other conditions.
