Spears' Parents: Brit's Life Is at Risk

In the declaration released Tuesday, Lynne claims that on the night of Spears' committal, she told her doctor that she had taken Adderall, an amphetamine used to treat attention deficit hyperactivity disorder (ADHD).

Over the past week, Lutfi and Spears' parents reportedly got into multiple scuffles in the hospital over who was in charge of her medical care, according to TMZ. Under the treatment of her psychiatrist, Dr. Deborah Nadel, Spears's stay was extended to a 14-day hold on Sunday, according to People magazine.

Speculation about the pop star being mentally ill has increased since her Jan. 3 breakdown, when she refused to give up custody of her children to ex-husband Kevin Federline. Currently, Spears does not have rights to visit her sons, and in recent months she has missed multiple court hearings in her custody battle.

Over the last year, Spears has been photographed shaving her head in public, furiously attacking a car with an umbrella and swimming in her underwear.
