Wikipedia
Parasuicide (from Greek παρά, para-, "near" or "resembling" and suicide) is a suicide attempt or gesture and self-harm where there is no result in death. It is a non-fatal act in which a person deliberately causes injury to him or herself or ingests any prescribed or generally recognized therapeutic dose in excess. The term was first coined in Edinburgh by Norman Kreitman. It is considered to be a serious public health issue.
Parasuicide is the strongest known indicator for a future completed suicide. Other researchers also include those in the definition who attempt suicide with the intent to kill themselves. Studies have found that about half of those who complete suicide have a history of parasuicide. Parasuicide is most common in adolescents and young adults.
