Understanding BPD
People can recover
BPD does not mean someone will always feel this way. In long-term research, many people stopped meeting the diagnostic criteria. A 24-year follow-up of people originally treated in hospital found that symptom remission was more common than recovery that also included work and relationships. Progress in one area may come before another.
This cannot predict one person’s future, but it gives reason for hope. Read what the long-term studies found and their limits.[1]
If self-harm or suicide is part of what is happening
Use these guides for what to do rather than trying to manage the risk alone.
