Longitudinal Study on Low-Dose Aspirin versus Placebo Administration in Silent Brain Infarcts: The Silence Study.

Background: We investigated low-dose aspirin (ASA) efficacy and safety in subjects with silent brain infarcts (SBIs) in preventing new cerebrovascular (CVD) events as well as cognitive impairment.

Methods: We included subjects aged ≥45 years, with at least one SBI and no previous CVD. Subjects were followed up to 4 years assessing CVD and SBI incidence as primary endpoint and as secondary endpoints: (a) cardiovascular and adverse events and (b) cognitive impairment.

Immunological profile of silent brain infarction and lacunar stroke.

Neuroinflammation is believed to be involved in the pathophysiological mechanisms of silent brain infarcts (SBI). However, the immunological profile of SBI has been scarcely investigated. In the context of a national research project named SILENCE, aimed at investigating clinical, biochemical and pathogenic features of SBI, we have measured the plasma profile of some inflammatory-related molecules in SBI patients (n = 21), patients with recent lacunar infarcts (LI, n = 28) and healthy controls (n = 31), consecutively enrolled in four Italian centres.

Cerebral blood flow changes in the different phases of migraine.

The haemodynamic changes that take place in migraine are reviewed focusing on cerebral blood flow (CBF) data measured with different techniques in patients suffering from migraine with and without aura during the different phases of attacks and in interictal periods. Special attention is paid to the factors underpinning the conflicting cerebral blood flow data and to pathophysiological implications of the CBF changes detected in migraineurs.
