Amber Heard suffers from two personality disorders involving “extreme effort to be the centre of attention” and is suspected of faking post-traumatic stress disorder from her marriage to Johnny Depp, a forensic psychologist has said.

Dr Shannon Curry spent two days with the actress in December last year before diagnosing her with a borderline personality disorder and a histrionic personality disorder.

Giving evidence at Heard’s libel battle with Depp, the psychologist identified symptoms including “making up stories” and “manipulation tactics”, and said the disorders can be driven by a “terror of abandonment”.
