Personality disorders are conditions where an individuals’ personality characteristics can cause regular and long term problems in the way they cope with everyday life and interact with other people; anti-social personality disorder (ASPD) and borderline personality disorder (BPD) are two types.
APMS (2007) describes these disorders as:
“ASPD is characterised by disregard for and violation of the rights of others. People with ASPD have a pattern of aggressive and irresponsible behaviour which emerges in childhood or early adolescence. They account for a disproportionately large proportion of crime and violence committed. ASPD was present in 0.3% of adults aged 18 or over (0.6% of men and 0.1% of women).”
“BPD is characterised by high levels of personal and emotional instability associated with significant impairment. People with BPD have severe difficulties with sustaining relationships, and self-harm and suicidal behaviour is common.”
In Horsham and Mid Sussex CCG, approximately 560 adults aged 16-64 were estimated to have borderline personality disorder, and 420 with antisocial personality disorder.
Applying sex-specific prevalence rates of borderline personality disorder to the West Sussex population aged 16-64 years (by CCG)
|Prevalence of borderline personality disorder||Estimate number of persons aged 16-64 with personality disorder|
|%Males||% Females||% all||Coastal West Sussex CCG||Crawley CCG||Horsham and Mid Sussex CCG||West Sussex|
|Borderline Personality Disorder||0.3%||0.6%||0.4%||1,130||290||560||1,980|
|Antisocial personality disorder||0.6%||0.1%||0.3%||850||220||420||1,480|

The presence of a personality disorder, notably antisocial personality disorder, may have considerable implications in the treatment and management of co-existing psychiatric and physical conditions. Co-existence of a personality disorder and another mental health problem is high.
