Mick Jagger diagnosed with 'acute traumatic stress disorder'

Sir Mick Jagger was diagnosed with acute traumatic stress disorder after the suicide of his long-term partner, L'Wren Scott, court papers have revealed.

The Rolling Stone developed the condition, which has symptoms such as flashbacks, nightmares, feelings of guilt and emotional numbness, after his fashion designer girlfriend took her own life in March this year, The Telegraph has reported.

If acute traumatic stress disorder persists for more than one month, it becomes post traumatic stress disorder.

Revelations about Sir Mick's mental state were made in court papers in L'Wren Scott's home state of Utah, as part of a dispute between the band and insurers in the wake of Scott's death.

Insurers claim they should not have to shell out the £8 million the band are demanding for cancelling a stretch of their world tour because 49-year-old Scott took her own life.

She was found by her assistant in her New York apartment on the morning of March 17. Coroners ruled she had hanged herself.

It was after this Sir Mick developed acute traumatic stress disorder and was instructed by doctors to take a month off, forcing the Rolling Stones to cancel live shows in Australia and New Zealand.

The underwriters say that after the Stones put in a claim they disputed it and began legal actions in the High Court in London and a court in New York.

They add that Sir Mick was not examined by a psychiatrist before abandoning the scheduled dates.
