Cryptogenic stroke and TIA: Suggested diagnostic approach while waiting for evaluation and treatment guidelines

Abstract

Background

Empiric strategies for secondary prevention in cryptogenic stroke and cryptogenic TIA are lacking. The best therapy to prevent recurrence depends on the cause of stroke. Attempting a correct diagnosis is therefore the fundamental goal of stroke treatment. Further investigation into the source of embolism if suspected, and determination of the etiology, even if demanding, is the needed prerequisite for optimal secondary prevention and risk reduction.

Aims

This paper discusses evaluation and treatment of cryptogenic stroke in light of recent years’ clinical trials results and developments in cardiology and neuroradiology. No ethical approval was needed for this work.

Results

Cardioembolism due to paroxysmal atrial fibrillation, patent foramen ovale, or cardiomyopathy; occult atherosclerosis from unstable plaques and hypercoagulable conditions seem to be the most common underlying causes to be revealed by further investigations. Treatment of these conditions can reduce the stroke recurrence significantly.

Conclusions

An individual approach and targeted diagnostics using advanced medical technologies in selected patients, who may benefit from a tailored treatment regimen, can help reveal a probable cause in the majority of strokes and TIAs previously classified as cryptogenic.
