Since I wasn't big on multiple personality disorder long before it was renamed DID, I wanted to do additional research for any updated info since the identification changed in 1994 to
dissociative identity disorder, and didn't want to be surprised by some novel assessment.
I only wish Dr. Grimmett's testimony came a week earlier to save me the time since she confirmed in her testimony that DID remains very rare -- she's never seen it and probably won't ever see it.
What percentage of the world has DID?
Dissociative identity disorder (DID) is a rare psychiatric disorder diagnosed in about 1.5% of the global population. This disorder is often misdiagnosed and often requires multiple assessments for an accurate diagnosis. May 17, 2022
IMO, the rub here is that the defense expert, Dr. Lewis, 85, is pretty much the pioneer for promoting DID as a criminal defense for murderers, But then there's not too much competition for experts of a rare mental condition used to keep criminals out of prisons.
But probably more important as evidence of LS being misdiagnosed by Lewis is that most patients generally spend 5-13 years in treatment before being diagnosed with DID. We know that LS fails this generality miserably.
IMO, the defense more or less threw a dart at the wall to come up with DID since narcissism is not a respectable or sympathetic excuse for murdering a little boy.
To summarize, the Diagnostic and Statistical Manual (DSM-5)criteria for DID include at least two or more distinct personalities. Each personality varies in behavior, sense of consciousness, memory, and perception of the outside world. Persons with DID experience amnesia, which essentially are distinct gaps in memory and recollections of daily and traumatic events. They cannot be directly related to substance use or part of cultural norms or practices. Importantly, these symptoms must cause a notable lack of functioning in day-to-day life
IMO, LS diagnosis was purchased and I believe the jurors will see through the smoke and mirror of sympathetic Dr. Lewis.
