Personality Disorders
Personality
disorders:
- personality disorders are pervasive chronic psychological disorders which
can greatly affects a person's life, usually having a negative affect on
one's work, family & social life.
- they exist on a continuum of both severity (mild-severe) and type
- while most people with mild personality disorders (or personality traits)
can live pretty normal lives, during times of increased stress or external
pressures, the symptoms of the disorder will gain strength & begin to
seriously interfere with their emotional & psychological functioning
- such people possess several distinct psychological features including
disturbances of:
- self-image
- ability to have successful interpersonal relationships
- appropriateness of range of emotion
- ways of perceiving themselves, others & the world
- ability to possess proper impulse control
- these disturbances come together to create a pervasive pattern of
behaviour & inner experience that is quite different from the norms of
the individual's culture & that often tend to be expressed in behaviours
that appear more dramatic than what society considers usual.
- there are many causes of personality disorders including:
- parental upbringing
- personality & social development
- genetic & biologic factors
- The DSM-IV lists several criterion that underlie all personality disorders
as follows:
- An enduring pattern of inner experience and behaviour that deviates
considerably from the expectations of society. This pattern is
manifested in two or more of the following ways:
- Cognition (i.e., ways of perceiving and interpreting self, other
people and events)
- Affectivity (i.e., the range, intensity, liability, and
appropriateness of emotional response)
- Interpersonal functions
- Impulse control
- The enduring pattern is inflexible and pervasive across a broad range
of personal and social situations.
- The pattern leads to clinically significant distress or impairment in
social, occupational, or other important areas of function.
- The pattern is stable and of long duration. Onset can usually be
traced back to adolescence.
- The enduring pattern is not in any way linked to another mental
disorder.
- The enduring pattern is not do to the use of controlled substances, or
a general medical condition.
- When learning about personality disorders it is extremely important to
remember that the only diagnosis is done by professionals with considerable
knowledge and exposure to personality disorders.
- It is quite easy for one to develop fourth year med school student
syndrome. This is a term referring to one's tendency to diagnose serious
diseases and disorders because they have a little information of the subject
and they see a few of the symptoms. All people have personality flaws; some
might be shy, some aggressive, some unable to deal with stress... this does
not mean that person has a personality disorder.
- Only people with extreme cases of persistent, maladaptive, and
dysfunctional personality traits that affect their lives meet the
criteria for personality disorders.
Types
of personality disorders:
- there are 10 basic types of personality disorders which can be grouped
into 3 clusters:
-
"odd, eccentric, psychotic" cluster:

Paranoid
-
Paranoid personality disorder is characterized by a distrust of others and a constant suspicion that people around you have sinister motives. People with this disorder tend to have excessive trust in their own knowledge and abilities and usually avoid close relationships with others.

They set unreasonably high standards for themselves and others, and tend to be very critical of others when they do not live up to these high standards.
