Mental Health Of The Nation: Personality Disorders

What makes you who and what you are? Where did your personality come from?

Well, we know some of it is inherited from your parents and grandparents; we all know that certain traits run in families. There are also many personality traits that we have learnt from our homes, schools, churches, friends - in fact, the whole of our culture. These are known as environmental factors.

There is also some degree of choice; there are parts of us that with hard work can be changed.

Our personalities are made up of a large number of traits. There are actions, attitudes and behaviours, hundreds and hundreds of them, such as being conscientious, dependable, honest, or more negative traits such as dishonest, pompous or just plain nasty.

There are, of course, hundreds of traits that can be measured, most of them existing within all of us to a greater or lesser degree. We all have them. This constellation of traits is only considered abnormal when groups of traits are either far too strong or completely absent. We all like our partners to be a little bit jealous but when the jeolousy trait has them inspecting underwear and making bizarre accusations then the jealousy trait is definitively abnormal.

It is when groups of traits are found together in abnormal quantities that the diagnosis of a personality disorder is made.

The concept of character goes back to ancient Greece; later in England the term ‘moral insanity’ came into use. Then psychopathic personality began to be used to describe anti-social behaviour not explained by psychosis. The current diagnosis of personality disorder is made when significant problems with relationships and self, along with certain pathological personality traits, are present over time.

They also must not be explained by a medical condition or in someone whose personality has not had time to develop.

These disorders tend to overlap and often co-exist and so are grouped into three clusters.

The first group consists of the paranoid, schizoid and schizotypal disorders: these people tend to be very odd, eccentric and often seem quite bizarre. They do not trust others and are suspicious, feel shame and hold on to grudges. It is difficult for them to build long-term stable relationships. There are similarities in thinking with people with the illness called schizophrenia but there is no evidence of psychosis.

A second group or cluster consists of avoidant, dependent and anankastic disorders and comprise of people who are excessively anxious and fearful. There is a severe lack of self confidence with an excessive need for others to look after them. There are great difficulties with relationships and social interactions. The anankastic type has similarities with the anxiety disorder OCD but the other personalty traits make relationships extremely difficult.

The third group of personality disorders is perhaps the most troublesome. The anti-social, borderline histrionic and narcissistic types combine to create great hardship to society. People with these disorders have a callous disregard for others, lack of empathy and remorse combined with an overvalued sense of self importance.

This group seems to be over-represented in the Bahamas, perhaps due to the high incidence of child abuse. These traits were valuable in times of war as these individuals have little fear and win medals for apparent bravery.

In times of peace, however, they are not constrained by a conscience - that little voice in the back of our heads that tells us when something is wrong and that nagging sense of guilt when we do mess up.

Imagine if that did not exist. It opens doors to despicable behaviour with absolutely no remorse. They can even pass lie detector tests.

These individuals miss out on so much it is clear they need help. Unfortunately, there are no pills or potions for these conditions and, whilst some benefit from talking therapies, those with a complete lack of a trait are blissfully unaware that there is something wrong with them. They are much more likely to blame others.

Present day psychiatry can help if someone really wants to change but with many there is little that can be done.

This is most easily explained for the "laid back" approach to life, especially parenting. It is not all in God's hands. We have responsibility for raising decent children. We have responsibility for creating a better society. We have failed to do so in The Bahamas for over a generation now. It will take at least a generation to fix, if it can be fixed. This aspect of Bahamian "culture" I find to be the most troubling. Take responsibility for the future our children will be inheriting. We are not doing so now. This is very clear.

Sadly it's the pharmaceutical enterprises that are driving everything today when it comes to labelling, diagnosing and treating the myriad of different types of mental illness. Psychologists and psychiatrists are steered for the most part wherever big pharma research and pill producers choose to take them with the goal being the maximization of profits for all concerned from writing scripts for expensive pills to charging hefty hourly rates for talking softly to patients. Keeping it all much more simple and less costly with typically better results was thrown out of the window many years ago by big pharma in the U.S., Germany, Switzerland and France. The long term effects of many of the medications prescribed today are intended to create permanent chemical imbalances that leave patients dependent on expensive pills for the remainder of their lives. My brother was a victim of all of this greed and foolishness....and it's also why most health insurers refuse to provide affordable significant coverage for most types of mental illness.
