Definitely a potential cause of the index stroke (examples): (a) Arterial dissection by A or B evidence (table 3), (b) Dolichoectasia with complicated aneurysm, (c) Polycythemia vera, thrombocythemia >800,000/mm3, (d) Lupus erythematosus, (e) Disseminated intravascular coagulation, (f) Criteria for antiphospholipid antibody syndrome, (g) Fabry's disease, (h) Concomitant meningitis, (i) Sickle cell disease, (j) Ruptured cerebral aneurysm with or without demonstration of spasm in the territory of the brain infarct, (k) Homozygote for hyperhomocystinuria

Unlikely a direct cause of index stroke (but disease is present): (a) Kinking or dolichoectasia without complicated aneurysm or plicature, (b) Arteriovenous malformation or saccular aneurysm, (c) Thrombocytosis >450,000 and <800,000/mm3, (d) Antiphospholipid antibodies <100 GPL units, (e) Mild hyperhomocysteinemia heterozygote
