Outline of Final Research Achievements

Selective neuronal damage develops following arterial occlusion with resultant ischemia of moderate severity. We measured the central benzodiazepine receptors (cBZRs) twice using positron emission tomography in patients with major cerebral artery disease. Progression of cortical neuronal damage manifested as a decrease in the cBZRs occurred in 50% of the patients and was associated with hemodynamic impairment at baseline and hemodynamic deterioration during follow-up. Hemodynamic deterioration was associated with a lack of statin use. Statin use may be beneficial against hemodynamic deterioration and therefore neuroprotective. Progression of cortical neuronal damage in surgically treated patients with hemodynamic impairment was larger than in medially treated patients with hemodynamic impairment.Using BZR decreases as objective markers of neuronal damage, bypass surgery was not superior to medical therapy in patients with hemodynamic impairment.
