What is Borderline
Personality Disorder?
Borderline
personality disorder (BPD) is a serious mental illness marked by
unstable moods, behaviour, and relationships. In 1980, the Diagnostic
and Statistical Manual for Mental Disorders, Third Edition (DSM-III)
listed BPD as a diagnosable illness for the first time. Most
psychiatrists and other mental health professionals use the DSM to
diagnose mental illnesses.
Because some people
with severe BPD have brief psychotic episodes, experts originally
thought of this illness as atypical, or borderline, versions of other
mental disorders. While mental health experts now generally agree
that the name "borderline personality disorder" is
misleading, a more accurate term does not exist yet.
Most people who have
BPD suffer from:
- Problems with
regulating emotions and thoughts
- Impulsive and
reckless behavior
- Unstable
relationships with other people.
People with this
disorder also have high rates of co-occurring disorders, such as
depression, anxiety disorders, substance abuse, and eating disorders,
along with self-harm, suicidal behaviors, and completed suicides.
