About Cholinesterase inhibitors  

  • Cholinesterase inhibitors are drugs that can increase communication between nerve cells in the brain. They are sometimes used to temporarily improve or stabilise the symptoms of people with dementia. 
  • Common side effects of cholinesterase inhibitors include vomiting, muscle cramps, headache and hallucinations. 
  • Certain chemical classes of pesticides work against bugs by interfering with, or ‘inhibiting’ cholinesterase but they can also be poisonous, or toxic, to humans in some situations. 

Who is Alexei Navalny? 

  • Navalny is an opposition leader who is a critic of Russian President Vladimir Putin. He recently collapsed on a plane after drinking tea while on his way to campaign in Siberia. He has been a thorn in the Kremlin’s side for more than a decade, exposing what he says is high-level graft and mobilising crowds of young protesters.
