Q

Difference between traits, disorder and episodes?

A

Traits of a condition are displayed by many people; these do not always cause problems

It is only a disorder if it is pervasive, not just related to specific situations, and causes distress and/or impairment of functioning in most areas

i.e: being shy does not indicate a personality disorder, nor does

Episodic behaviour is more likely due to another disorder, e.g: affective disorder

~10%; they are more common than T1DM and T2DM combined, IBD, MS, epilepsy, RA and asthma, i.e: many cases are undiagnosed

1/10 people in the general population have a personality disorder; this is higher in psychiatric patients, due to greater unmet needs and greater impairment

Those with obsessive-compulsive PD agree with themselves/their actions, whereas those with OCD know that it is excessive (as in all anxiety disorders) and become frustrated with themselves, i.e: OCD is egodystonic and obsessive-compulsive PD is egosyntonic

OCD is very treatable, whereas obsessive-compulsive PD is difficult to treat

Q

Are anti-social PD and psychopathy the same thing?

A

They are not; antisocial PD is largely based on behaviour but psychopathy describes deficits in emotional and cognitive functioning

28
Q

Features of psychopathy?

A 
Factor 1 (interpersonal / affective):
• Facet 1 (interpersonal) - glibness (superficial charm), grandiose self-worth, pathological lying, conning / manipulative
• Facet 2 (affective) - lack of remorse, shallow affect, lack of empathy/callous, failure to accept responsibility for actions
Factor 2 (social deviance):
• Facet 3 (lifestyle) - need for stimulation (prone to boredom), parasitic lifestyle, lack of realistic long-term goals, impulsivity, irresponsibility
• Facet 4 (antisocial) - poor behavioural controls, early behavioural problems, juvenile delinquency, revocation of condition/release, criminal versatility
29
Q

Occurrence of psychopaths?

A

Not all psychopaths are imprisoned; many are successful in corporations

30
Q

Prognosis of PD?

A

Fairly stable over time but this does not mean that change is impossible; patients’s symptoms/behaviour can improve over time

31
Q

General basis for treatment of PD?

A

Not much evidence but TREATMENT OF CO-MORBIDITY is effective and is the focus, e.g: depression, anxiety

32
Q

Which types of PD are considered non-responders?

A

Little guidance on the treatment of the following

Cluster A:
• Schizoid PD
• Paranoid PD

Cluster B:
• Histrionic PD
• Dissocial PD

Cluster C:
• Anankastic (Obsessive-
Compulsive) PD
• Avoidant PD

33
Q

Treatment of avoidant PD?

A

Social skills training helpful for some patients, by helping to increase self-efficacy and functioning

Anti-depressants

NOTE - again, not much evidence

34
Q

Treatment of boderline PD?

A

Main psychological treatment is Dialectical Behavioural Therapy (DBT)

‘Mentalisation’ is popular but there is less evidence for it

Drug treatment primarily for co-morbid conditions (no drug has a license for borderline PD):
• MAOIs may be effective for co-morbid depression and borderline PD
• Anti-psychotics may have a role, mainly Olanzapine (weight gain) and haloperidol have evidence
• Topiramate for anger and aggression

35
Q

What is DBT?

A

Complex package of groups, firm boundaries and management of interpersonal issues, mainly affecting suicidal behaviour; it attempts to combine behavioural approaches with concept such as acceptance and mindfulness

It is hard work and has a high drop-out rate

36
Q

What is mentalisation?

A

Process by which we interpret out own actions as being meaningful, based on our own internal mental states; impaired ability to mentalise apparently affects our ability to regulate our emotions and maintain interpersonal relationships

NOTE - using this as a treatment is not supported by as much evidence as DBT

37
Q

Treatment of antisocial PD?

A

Psychological interventions - group-based cognitive and behavioural interventions, in order to address problems such as impulsivity, interpersonal difficulties and antisocial behaviour

Pharmacological interventions - not routinely used
