Personality disorders are a classification of mental disorders
characterized by maladaptive patterns that disrupt a person's ability to
function in everyday life and/or cause extreme distress and the
inability to get along with other people.
As you read, you may recognize someone you know in the symptoms of
some of these disorders, but keep in mind that while a person may have
some of the symptoms of a mental disorder, this does not necessarily
mean he has the disorder itself. So don't go diagnosing your friends
with a personality disorder or you just might not have any friends left!
Antisocial Personality Disorder
Probably the best-known personality disorder is antisocial
personality disorder. People with this condition will manipulate or
exploit others to get what they want, and this behavior if often
characterized as criminal.
In the past, people have often called people with this disorder
psychopaths or
sociopaths, but psychologists now note that each of these represents a distinctly different mental disorder.
The DSM states that in order to diagnose an individual with
antisocial personality disorder, he must be at least 18 years old and
have a history of persistent disregard for the rights of other people
since at least the age of 15. They must also exhibit a history of at
least three of seven behavioral problems:
- Impulsive and cannot plan ahead
- Irresponsible and fails to meet obligations
- Repeatedly gets into physical fights
- Repeatedly breaks the law
- Lacks guilt or regret for hurting others
- Deceitful
- Has a reckless regard for his own safety or the safety of others
While genetic factors are thought to play an important role in
antisocial personality disorder, the exact cause is still unknown.
Unfortunately, this disorder is also one of the most difficult to treat.
People with this mental disorder rarely seek treatment on their own, so
most are only diagnosed and treated after they have come into contact
with the criminal justice system.
Narcissistic Personality Disorder
Narcissistic personality disorder is characterized by
self-centeredness, lack of empathy for others, and an exaggerated sense
of self-importance. Individuals with this disorder consider themselves
to be better than everyone else. They expect everyone else to shower
them with attention and favors, though they very rarely, if at all,
return the favor. They are self-absorbed to the point where they are
obsessed with their own self-importance, brilliance, and power. They
are, essentially, in love with themselves.
Borderline Personality Disorder
Borderline personality disorder (BPD)
is a personality disorder in which an individual has a history of
unstable relationships — one minute the relationship will be passionate
and intense as the partner is idealized, but in the next moment, the
relationship takes a dive as the partner is suddenly of little or no
value.
A person with borderline personality disorder is often
self-destructive and may threaten to commit suicide. Drugs are sometimes
a part of her life. Impulsiveness is also characteristic of this
disorder, as is emotional instability.
Causes of Mental Disorders
Now that you've been able to take a closer look at some of the more
common mental disorders and have seen how they can be debilitating to a
person's life, you are likely wondering what could possibly cause such
disorders. There isn't a simple and exact answer for this. Mental health
professionals and researchers are constantly studying the causes of
mental disorders in an attempt to better understand and treat the
disorders.
Biological Factors
Some mental health professionals are of the belief that mental
disorders are caused solely by problems in the brain and nervous system.
As you know, the nervous system is a delicate and complex system in
which there is a constant hum of activity that keeps your body alive and
functioning well. If there were to be any damage to or a kink in the
brain — the executor of the nervous system — the system could be thrown
out of whack, possibly resulting in a mental disorder. For instance, the
brain's prefrontal cortex is responsible for impulse control and
planning. Should this part of the brain be damaged, a person may suffer
impulsiveness and an inability to plan ahead, a symptom of
schizophrenia.
These people have also shown that some of the biological factors of
mental disorders are hereditary and that some people are more
susceptible to particular mental disorders than others. For instance,
research has shown that major depression is often a heritable mental
disorder. Also, as you've surely heard, addiction is thought to
originate in a person's biochemistry, and those with a genetic
predisposition to addiction are more likely to suffer an addiction.
Psychological Factors
On the other hand, there are those who believe that psychological
factors — such as traumatic experiences, past conflicts, the way parents
behaved toward a child, etc. — are responsible for the development of
mental disorders. For example, post traumatic stress disorder is a result
of a traumatic experience; it is the body's reaction to and coping
mechanism for past events of heightened stress. A mental health
professional believing in this theory would focus solely on the
traumatic event and its effects in an attempt to help the patient
overcome this disorder. Certain phobias, also, have shown that they are a
result of psychological factors. For instance, someone with the fear of
the number thirteen may have developed the phobia due to societal
stimulation or cultural tradition.
Working Together
Many mental health professionals and researchers in the field believe
that the causes of mental disorders are found among a combination of
biological and psychological factors. For instance, someone may have a
genetic predisposition toward a certain mental disorder, such as
addiction, but the onset of the mental disorder is triggered by a
psychological event, such as being exposed to psychoactive drugs during
adolescence. Borderline personality disorder is thought to be based on a
problem with the emotion regulation system, so that emotions are
experienced much more intensely than normal. Because feelings like
frustration, hurt, or anger are so much more powerful even over small
things, people with BPD elicit reactions such as “Just get over it”;
“You're not that upset”; or “You're just looking for attention.” While
parents of typical children often teach them how to self-soothe and deal
with feelings, parents of people with BPD may not have the skills
themselves to deal with extra-intense emotions. After a few years,
people with BPD learn to hide their feelings — until they can't anymore,
and the pain is simply intolerable. That's when they may hurt
themselves, which then starts the consequences all over again. As stated
before, the causes of mental disorders are continuously being
researched and studied, and treatments are continuing to advance every
day.
