Personality disorders

Please scroll to the bottom to see the resource listing.

In essence a personality disorder is a pattern of destructive thoughts instead of constructive ones.  Most people have some symptoms of a number of personality disorders, but they do not impact a persons life to the same degree.  There are many different types of personality disorder.  The most common in North America are borderline personality disorder, obsessive compulsive personality disorder, and narcissistic personality disorder.   Quite often these diagnoses don’t happen until adulthood.  All of these disorders can go hand in hand with depression or anxiety and the treatment is generally a mixture of individual and group behavioural therapy.


Borderline Personality Disorder - People with BPD are highly sensitive and often have severe body image issues.  Often there is a pattern of instability in relationships and self-damaging behaviours like cutting or substance abuse.

Obsessive-Compulsive Personality Disorder   People with this disorder require control and order in all things.  When forced to make decisions on the fly it becomes a laborious and painful process.

Narcissistic Personality Disorder   Narcissistic personality disorder is characterised by grandiose behaviour with a lack of empathy towards others.

Antisocial Personality Disorder  Sufferers have a lack of empathy for others and it includes a pattern of disregarding other people’s rights.

Avoidant Personality Disorder   People with this disorder have pervasive feelings of inadequacy that lead to social inhibition.

Dependent Personality Disorder  Sufferers fear they can’t live their life without help from the important people in their lives, they have a debilitating insecurity and fear of abandonment.

Histrionic Personality Disorder  Characterised by attention seeking behaviour, those with this disorder are prone to extreme emotionality and are uncomfortable when not the centre of attention.
