In England, it is estimated that around 1 in 20 people has a personality disorder. However, many people have only mild conditions so only need help at times of stress (such as bereavement). Other people with more severe problems may need specialist help for longer periods.
Manypeople recover from personality disorders over time. Psychological or medical treatment is sometimes helpful; sometimes support is all that is needed. This depends on the severity of the disorder and whether there are ongoing problems.
