Halfway through Netflix's new Britney Vs. Spears documentary, filmmaker Erin Lee Carr and journalist Jenny Eliscu receive leaked court documents that shed light on one of the most puzzling revelations from the Framing Britney Spears and the BBC's Battle for Britney documentaries: Britney Spears' dementia diagnosis.

Spears' diagnosis was reportedly noted in court documents at the beginning of Spears' conservatorship in 2008, as Jamie Spears, her father, filed for conservatorship citing "dementia placement or treatment." Other than that, not much was known about this alleged diagnosis or Spears' medical treatment at large, until now. New documents in Britney Vs. Spears give a bit more detail about the dementia diagnosis, and the doctor who allegedly gave it to her.

According to court documents, Dr. James Edward Spar was a physician involved in declaring Spears mentally incapacitated to the point of being unable to manage her own affairs. The 2008 report claimed that Spears "lacks the capacity to understand or manage her financial affairs without being subject to undue influence," among other things. He reportedly left the case in 2013.

Spar appears in the documentary, but refused to confirm anything relating to Spears' case, including whether or not he was part of a medical team that evaluated her in 2008. Spar, who worked as a geriatric psychiatrist, didn't even admit to meeting her. "I'm not going to acknowledge that I've ever met her," he told Carr, citing confidentiality. The only thing he would confirm is that he does specialize in dementia and has been brought in to consult on many conservatorship cases.
