Migraine has become an important vascular risk factor during the past few years, along with the presence of white matter and clinically silent ischaemic lesions. Whether these findings contribute to the migraine becoming chronic has been a source of debate. People with chronic migraine also have a less favourable metabolic profile. An exhaustive review of the literature has been made in order to try to clarify the relationship between migraine and vascular risk factors. ⋯ Since migraine is an independent vascular risk factor, a better control of migraine attacks, as well as other possible concomitant vascular risk factors, should decrease the likelihood of a stroke. Overall, the real risk of infarction is low, with 3.8 new cases per 100,000 women and year.

Comparative Study
[Low sensitivity of the echocardiograph compared with contrast transcranial Doppler in right-to-left shunt].
Contrast transcranial Doppler (c-TCD) has a high sensitivity for detecting right-to-left shunt (RLS), and is probably higher than transthoracic echocardiography (TTE) and comparable with transesophageal echocardiography (TEE). ⋯ TTE and TEE show a considerable number of false negatives for RLS detection. Clinical studies should consider the c-TCD as the best technique to diagnose RLS when a paradoxical embolism is suspected.

The potential relationships of interest between authors, reviewers, editors and financial management of the journals can lead to a conflict of interest in their performances. ⋯ Potential conflicts of interest should be transparent and the knowledge and values should be an objective of the magazines. The declaration of relationships should be required in the communication of research, but their existence should not prejudge misconduct.
