In a new review in Science, the authors call the identification of the anesthetic and “club drug” ketamine as a rapid treatment for depression “arguably the most important discovery in half a century” of research on the condition.
In any given year, 7% of adults suffer from major depression, and at least 1 in 10 youth will reckon with the disorder at some point during their teenage years. But about 20% of these cases will not respond to current treatments; for those that do, relief may take weeks to months to come.
There is one treatment, however, that works much faster: the anesthetic and “club drug” ketamine. It takes effect within hours. A single dose of ketamine produces relief of depression that has been shown in studies to last for up to 10 days; it also appears to reduce symptoms of bipolar disorder and suicidal thoughts. Now, a new research reviewpublished in Science calls the discovery of these effects of ketamine, “”arguably the most important discovery in half a century” of depression research.
