Depression affects around half of people with Parkinson's disease and significantly adds to the burden already faced by patients. However, existing antidepressants are not effective in treating depression in Parkinson's disease, and new treatments are urgently needed. Ketamine is a drug that has been traditionally used as an anesthetic, but based on the discovery that it rapidly reduces symptoms of depression, is now being used as an antidepressant. Ketamine holds significant potential for effectively treating depression in Parkinson's disease.
