BPD, affecting 1-2% of the UK population, is most common in early adulthood, with 75% of cases occurring in women. It is also now being treated in child and early adult mental health services.

BPD leads to emotional regulation and impulse control challenges, with 75% of those diagnosed with BPD attempting suicide and 10% resulting in death.​

BPD experiences vary widely due to its diverse symptoms, which can overlap with conditions like depression, anxiety, eating disorders, PTSD, drug and alcohol abuse, and bipolar disorder.​

 

Other terms for BPD include Emotionally Unstable Personality Disorder (EUPD) and Emotional Intensity Disorder (EID) - it’s down to personal preference, and some prefer no label at all.

A brief overview of BPD follows, with more extensive information provided in our BPD booklet.

The nine main symptoms of BPD

Causes

BPD is a biologically based disorder caused by brain chemicals and development, as well as genetics, environment, or a combination of both.

 

Developmental factors like stress, childhood trauma, or growing up in a hostile or unstable/unsettled environment’ can also contribute.

Treatment

Despite popular belief, BPD is treatable and manageable with medication and/or psychotherapy, including Cognitive Behavioural Therapy (CBT), Dialectical Behavioural Therapy (DBT), Mentalisation-Based Therapy (MBT), and art therapies. There is no specific medication for BPD, though some can help with co-morbid conditions, such as bipolar, depression, and anxiety.

NHS treatment has improved significantly. Consult your GP to find out local services and support for family members and caregivers.
