European medical sources report the lithium found by the Berlin doctors in Navalny's blood is commonly used to treat bipolar disorders. It is known to depress the butyryl cholinesterase which Navalny's laboratory testing also revealed in the German hospital.
According to a leading medical psychiatrist treating patients for depression and bipolar disorder, if Navalny was also being treated to stabilise his insulin level with the well-known Metformin, that drug is known to be a cholinesterase inhibitor.
When Navalny appears in a Moscow court, his full medical records, including the laboratory tests recorded at Omsk Emergency Hospital No. 1 before he left for Germany, are likely to be produced in evidence. His previous medical history, including reported episodes of acute pancreatitis and diabetes, which Navalny's spokesmen have denied, is also likely to be revealed.
At stake is a courtroom test of Navalny's allegation that he was attacked with a Novichok nerve agent by men of the Federal Security Service (FSB). Also at stake is a forensic test of the medical evidence of Russian, German and other doctors that Navalny "collapsed because of the drugs he was taking", as the expert source on the use and abuse of benzodiazepines says he suspects.
The western government case is that Navalny was the target of the crime of attempted murder, and that a Russian-made Novichok was the weapon used. The Russian government case is that the medical evidence is of a metabolic crisis caused by the combination of alcohol, lithium, and benzos taken by Navalny himself.
Comment: The complicated and overlapping connections to this political cabal show exactly why President Trump has been so valuable to the American people and why he changed course in so many agreements. It also shows the depth, breadth and strength of his opposition and likewise his courage to uncouple its hold on America.
