Altogether, these results suggest that delirium rats induced by scopolamine may be correlated with an increased cerebral concentration of 5-HT and dopamine neurotransmitters system; the selective 5-HT(1A) antagoniszts can reverse the delirium symptoms at some extent through tendering PI3K/Akt/mammalian target of rapamycin complex 1 (mTOR) activation-induced NLRP3 activity and then reducing IL-1β release.
This study suggests that delirium is not scarce in patients with AIS admitted to the non-intensive stroke unit, and that delirium developing after AIS seems not to be associated with serum TNF-alpha, IL-1 beta, IL-18, BDNF and NSE but is associated with length of hospital stay and stroke severity.
After adjusting for stroke severity and infections, higher ex vivo TNFα (OR 0.29, 95%CI 0.11-0.72, P = 0.01), IP-10 (OR 0.25, 95%CI 0.08-0.73, P = 0.01), IL-1β (OR 0.42, 95%CI 0.20-0.89, P = 0.02), and IL-12 (OR 0.07, 95%CI 0.01-0.70, P = 0.02) release was associated with the reduced risk of delirium.
