Wiki
"Kidder was diagnosed with bipolar disorder, which was the cause of a widely publicized manic episode that she experienced in April 1996. At the time, Kidder had been working on an autobiography when her laptop computer was infected with a virus, which caused it to crash and her to lose three years' worth of drafts.[27] Kidder flew to Los Angeles to have the computer examined by a data retrieval company, who ultimately were unable to retrieve the files.[27] Kidder then entered a manic state and disappeared for four days. She was found in a backyard by a homeowner and was taken by the Los Angeles Police Department to Olive View Medical Center in a distressed state, the caps on her teeth having been knocked out during a rape attempt.[27] She was later placed in psychiatric care.[27] In 2007, Kidder said that she had not had a manic episode in 11 years, and credited her well-being to orthomolecular medicine.[36]"
