No Genn, I do not think DID is a condition to be treated with medication. It is not a psychosis, and nor is there a physiological component to it. Some theories say it is a psychological defense or adaptation, and others say it is due to a lack of psychological integration. What is certain is that there is no research that supports the treatment of DID with medication. General pscyhological symptoms that may accompany DID can be treated with say, anti depressants or anti anxiety medication, but no medication will 'fix' the DID itself.
