Educational Pearls
- Patients with an ischemic stroke from occlusion of the left middle cerebral artery often present with aphasia in addition to other neurological deficits.
- A recent study looked at patients presenting with suspected stroke. Of the 700 patients recruited, 3% had isolated aphasia on exam. On follow-up, none of the 3% had evidence of stroke on imaging. Underlying causes of the isolated aphasia in these patients included syncope, infections, seizures were the underlying cause.
