Personality disorders

  We all have a personality. Personality is that collection of relatively permanent characteristics that makes us different from each other. It’s generally how we first think of individuals or describe them. Psychiatrists inevitably became interested in personality. First because they have to distinguish between illness and personality (is this person suffering from a depression or are they always morose and pessimistic?). But they soon noted that there were personality types that were more commonly associated with some of the disorders they treated and for this reason they used the same or similar terms. The schizoid personality is rather distant and strange and the paranoid personality is over-sensitive and prone to suspicion. The hysterical is prone to intense fluctuating emotions, needing passionate relationships and to be the centre of attention, whereas the obsessional is careful and inflexible. The psychopathic personality (variously called sociopathic and antisocial) is not just a delinquent but is characterized by an absence of feeling for those around him or any sense of remorse. Their difference from ordinary criminals is such that prisons have as much difficulty dealing with them as do psychiatric hospitals.

  The role of psychiatry in the treatment of extremes of personality, ‘personality disorders’ (PD) is controversial (Chapter 6) and most psychiatrists are sceptical that they have any specific cures. However, personality affects everything about us and so the treatment of any psychiatric disorder will require proper attention to personality. Different societies present problems for different personalities and the classification of personality disorders is changing. The difference between the sexes in the distribution of the two most prominent diagnoses is striking. Currently women are much more likely to be diagnosed with ‘borderline’ PD (fluctuating, intense emotions and difficult relationships, self-harm and low selfesteem, quite similar to the old-term ‘hysterical’ PD) and men with ‘antisocial’ PD (violence, delinquency, and impulsiveness quite similar to ‘psychopathic’ PD). It is not hard to see how these two disorders could be manifestations of the same personal alienation and disappointment but expressed as ‘different’ disorders because of how our culture moulds the behaviours of men and women.

Addictions

  It is far from clear what psychiatry’s role should be in the treatment of alcohol and drug abuse. Most people who abuse them do not have mental illnesses. However there are a number of compelling reasons why psychiatry is involved. People with mental health problems have a very much increased risk of turning to drink or drugs, possibly to dull the pain in their lives (particularly in depression and personality disorders). Drug and alcohol abuse also makes getting better much more difficult. It is almost impossible to recover fully from depression while drinking to excess and young schizophrenia patients who abuse drugs find it difficult to attain control of their illnesses.

  Addictions can also cause mental illnesses. Severe alcohol abuse can lead to paranoid psychoses, delirium tremens, depression, and eventually dementia. Amphetamine and cocaine are associated with quite severe paranoid disorders which can result in violence; acute psychotic reactions are common with LSD and Ecstasy. In addition the poverty and social chaos associated with illegal drug use can lead to depression and despair. So psychiatry is inevitably involved with treating alcohol and drug misuse. However, whether psychiatry should lead it, or simply be one of a range of inputs available to help, can be debated, as can the benefit of classifying addictions as illnesses.
