Why nobody discusses the adverse psychiatric effects of chloroquine in case it might become the future treatment against COVID-19?

Chloroquine represents at least a basic prototype antimalarial drug, widely applied in several branches of medicine and also recently against a new zoonotic origin coronavirus. At present, there is little awareness of chloroquine's psychiatric side effects, which appear to be overlooked by the Scientific Committee, although they may manifest in a worryingly wide range of symptoms. This is likely to interfere with the course of specifically long-term (high-dose) COVID-19 treatment in some aggravated forms (25% of coronavirus patients were still carrying the virus 6 days after taking hydroxychloroquine).

A simple approach to studying cerebral blood flow during psychological stress.

The purpose of this work was to determine, in the Wistar male rats, the role of the stress system in the control of cerebral hemodynamics induced by emotional stress (air jet). Blood flow rates in the internal carotid arteries have been obtained using chronically implanted Doppler probes. In this investigation, air-jet stress provokes a rapid and substantial elevation of blood pressure combined with hyperemia and vasodilation.
