DOCTORS TEST KETAMINE AS AN INSTANT REMEDY FOR DEPRESSION

criminalwisdom:

Traditional antidepressants like Prozac work on a group of chemical messengers in the brain called the serotonin system. Researchers once thought that a lack of serotonin was the cause of depression, and that these drugs worked simply by boosting serotonin levels.

Recent research suggests a more complicated explanation. Serotonin drugs work by stimulating the birth of new neurons, which eventually form new connections in the brain. But creating new neurons takes time — a few weeks, at least — which is thought to explain the delay in responding to antidepressant medications.

Ketamine, in contrast, activates a different chemical system in the brain – the glutamate system. Researcher Ron Duman at Yale thinks ketamine rapidly increases the communication among existing neurons by creating new connections. This is a quicker process than waiting for new neurons to form and accomplishes the same goal of enhancing brain circuit activity.
