Victims of childhood abuse also suffer from different types of physical health problems later in life. Some reportedly suffer from some type of chronic head, abdominal, pelvic, or muscular pain with no identifiable reason. Even though the majority of childhood abuse victims know or believe that their abuse is, or can be, the cause of different health problems in their adult life, for the great majority their abuse was not directly associated with those problems, indicating that sufferers were most likely diagnosed with other possible causes for their health problems, instead of their childhood abuse. One long-term study found that up to 80% of abused people had at least one psychiatric disorder at age 21, with problems including depression, anxiety, eating disorders, and suicide attempts. One Canadian hospital found that between 36% and 76% of women mental health outpatients had been sexually abused, as had 58% of women and 23% of men schizophrenic inpatients. A recent study has discovered that a crucial structure in the brain's reward circuits is compromised by childhood abuse and neglect, and predicts Depressive Symptoms later in life.
