One study demonstrated of 100 women with a documented medical history of child abuse as children showed that 38% were unable to recall that abuse 17 years later. In the USA in 1993 it was reported that millions of dollars in insurance payments was underwriting years of therapy for thousands of patients who claim to have recovered memories of childhood abuse. The therapy may have been sought for other purposes supposedly quite unrelated to past abuse. Such recovery was virtually non-existent in the 1970s and is having a profound effect on the legal system. The statute of limitations for childhood sexual abuse has been withdrawn in many states in the USA leading to criminal charges with awards up to $5 million.
