Ammonia is very toxic to the brain and new research shows why: the glial cells ability to remove potassium is perturbed. The picture shows individual glial cells deep in the brain of live mice, as well as a microelectrode used to measure electrical activity in nerve cells subjected to two-photon laser microscopy.
Until now, we have had limited knowledge on the mechanisms underlying ammonia toxicity to the brain. In healthy people the liver will convert ammonia into urea, a substance which washes out with the urine. People with impaired liver function will, however, be unable to rid their body of ammonia fast enough. The result is excessive concentrations of ammonia in the blood. This husband-and-wife team are the lead scientists behind the new findings.
Their findings were recently published in the prestigious medical journal Nature Medicine. This new knowledge may lead to new and improved treatment of patients suffering from liver coma and seizures, including adults with alcoholic liver failure, children with congenital liver enzyme deficiency and potentially, epileptic children with normal liver function.

Conditions that favor the occurrence of ammonium toxicity include the use of ammonium containing nitrogen fertilizers ammonium nitrate, ammoniated phosphates or fertilizers that are converted to ammonium urea.
Manures can also release ammonium.
