Ketamine as a Treatment for Depression?

The video discusses ketamine's use in treating depression, focusing on esketamine, a nasal spray approved by the FDA in 2019 for treatment-resistant depression. Esketamine acts faster than traditional antidepressants but is not a first-line treatment. It is administered under supervision due to potential side effects like increased blood pressure and dissociation. The mechanism involves altering glutamate signaling, potentially increasing brain plasticity. While promising, more research is needed on long-term effects. The video also warns against unapproved ketamine treatments and advises consulting a doctor for safe options.
