“…Therefore, patients at risk for stroke with unfortunate collateral status (thus portending poor outcome) could particularly profit from a lithium treatment at low concentrations via a generally improved endothelium-dependent vessel relaxation capacity. This might be speculative, but on the other hand, the lithium-augmented cerebrovascular relaxation capacity may party explain, why continuous lithium treatment can reduce the risk for stroke (Lan et al, 2015) or may improve neurologic recovery after cortical stroke (Mohammadianinejad et al, 2014) potentially caused by various beneficiary effects on neurons (Doeppner et al, 2016; Vosahlikova and Svoboda, 2016), or platelets (Barry et al, 2003) including the direct ones on vascular and cerebrovascular endothelium (Afsharimani et al, 2007; Rahimzadeh-Rofouyi et al, 2007; Bosche et al, 2013, 2016), as presented here. Directly or secondarily impaired endothelial barrier after ischemia and hemorrhages followed by vasogenic edema formation (Stokum et al, 2016) were known to be highly relevant for clinical outcome of various types of stroke (Hacke et al, 1996; Bosche et al, 2003; Macdonald, 2014; Wijdicks et al, 2014; Urday et al, 2015).…”
