Though Amy Winehouse's cause of death has yet to be determined, the singer's father Mitch Winehouse believes that she might have suffered a seizure during her detox.

"Everything Amy did, she did to excess," Mitch Winehouse told Anderson Cooper on the set of his new show "Anderson," which debuts Monday. "She drank to excess and did detox to excess."

Though there were no illegal drugs found in Amy's system, her father suspects that the anti-anxiety drug Librium, which is used to treat withdrawal symptoms during detox from alcohol, might have been a factor in her death. He told Cooper that his daughter had seizures, brought on my alcohol withdrawal but had been improving before her sudden death.

"The periods of abstinence were becoming longer, and the periods of drinking were becoming shorter," Mitch told Cooper, the Associated Press reports.

In the debut of his new daytime series, Anderson Cooper conducted an interview with Amy's parents Janis and Mitchell and with her boyfriend Reg Traviss about the singer's untimely death. Check your local listings for the show's air time.

The troubled 27-year-old jazz and soul singer was found dead in her London home by her bodyguard on July 23. Winehouse, who battled drug and alcohol addictions for years, is survived by her parents and her brother and has no children.

Winehouse's funeral was held on July 26 and was attended by her family and friends such as Mark Ronson, who produced the singer's Grammy-winning single "Rehab" and her 2006 album "Back To Black," as well as reality star and actress Kelly Osbourne. She wore her hair in a beehive, mimicking Winehouse's signature look. The singer was set to tour Europe, starting in June. But a botched performance in Serbia on June 18, during which Winehouse was booed off stage for being late and displaying odd behavior, prompted her to cancel the rest of her concerts.

Sales of Winehouse's music have soared since her death and it was reported last week that Winehouse left behind several unreleased tracks that could be put together for a posthumous album.

Winehouse's family set up a foundation in London to help those with drug and alcohol addiction. Cooper's new show donated $50,000 to the foundation, according to USA Today.
