Summary
Late-life migrainous accompaniments, often mimicking transient ischemic attacks, are analyzed in 85 new cases. Findings support this benign neurological condition, aiding in appropriate patient management.
Area of Science:
- Neurology
- Neuroscience
Background:
- Transient ischemic attacks (TIAs) can be mimicked by late-life migrainous accompaniments.
- Previous studies have presented cases of this condition.
Observation:
- 85 new cases of late-life migrainous accompaniments were analyzed.
- Cases presented with varied neurological symptoms including visual disturbances, paresthesias, speech alterations, and weakness.
- Headache was present in 40% of cases, with a 65% history of recurrent headaches.
Findings:
- The study supports the concept of late-life migrainous accompaniments as a distinct neurological entity.
- The condition is generally benign and can account for some cases of TIA with normal angiograms.
- Categorization of symptoms included visual, sensory, speech, and motor deficits, with a significant portion presenting without visual symptoms.
Implications:
- Understanding migrainous accompaniments is crucial for accurate diagnosis, differentiating them from TIAs.
- This knowledge facilitates rational management strategies for patients presenting with these episodes.
- Recognizing this benign condition prevents unnecessary investigations and interventions for TIA.
