Research into BPD
SPDN
Jeremy Hall
Borderline Personality Disorder
• First defined by Gunderson
• Core features– Affective instability– Interpersonal difficulties– Impulsivity
• Heritability about 40%
• Strongly associated with early life stress
The Scale of the Problem
• BPD affects 1-2% of the population
• BPD accounts for 10% OPD contacts
• BPD main diagnosis in 6% admissions
• Frequent cause of attendance at A&E
• Associated with a 10% risk of suicide
Current Treatments
• 1. Pharmacological Treatments– Antidepressants only if concurrent depression– Antipsychotics for perceptual disturbances– Some evidence for mood stabilisers– All trials very small– NICE unable to recommend any treatment
Current Treatments
• 2. Psychological Treatments– Best evidence is for DBT– Some evidence also for CBT– HOWEVER
• Trials generally small• Limited availability • Not suitable for all
How can Research help?
• Psychological Research– Larger studies– “Real-life” settings
• Biological Research– Develop measures of deficits in BPD– Relate these to changes in the brain– Develop new treatments
Our Research
• Developing measures of BPD symptoms– Affective responses– Interpersonal interactions– Impulsivity
• Determining their specificity to BPD
• Developing translational assessments
Emotion and Impulse Study
• 1. Background information
• 2. Symptom severity
• 3. Computer tests of:– A. Emotion processing– B. Social responses– C. Impulsivity
Who did we study?
• 20 people with symptoms
• 20 people without symptoms
• Age range 20-55
• 75% female
What did we find out?

Conclusions
Conclusions
• We could measure difficulties in core areas:– Emotion processing– Social responses– Impulsivity
• What does this mean in the brain?
Basis in the brain?
