Ketamine's antidepressant effect is a result of the enhancement of Kcnq2 potassium channels in a certain subtype of glutamate-sensitive neurons.
Researchers explore the effect psychedelics have on the brain and how they are effective at treating depression.
Overall, people who used antidepressants to manage depression long-term did not have a better quality of physical or mental health than those with depression who did not use prescription medication to manage their symptoms.

People with untreated depression have lower levels of mitochondrial proteins. For those who responded to the SSRI antidepressants, the proteins returned to a normal level, but showed no increase in those who did not respond to medication.
A comparison of medical records reveals people who took SSRI antidepressants, specifically fluoxetine (Prozac), were less likely to die of COVID-19 than a matched control group. The findings add to a growing body of evidence that SSRIs may have beneficial effects against the worst symptoms of coronavirus.
