Personality disorders usually refer to personality traits that are extreme or that cause enough difficulty in a person’s life to interfere with daily functioning to the point of “disabling.”

A true personality disorder is more severe than simple negative personality traits we all show at various times throughout our lives.

The medical definition of personality disorder is:

•   Long-term, pervasive, inflexible patterns of thoughts and behaviors that are not well adapted or do not fit within the range of behavior considered normal. These patterns of “abnormal” thoughts and behaviors lead to significant problems in the ability to reason and/or interact with others and/or to behave appropriately.

A personality disorder can appear at any time in a person’s life, including old age. It is estimated that 10% of older adults living at home may have a personality disorder. The figure is higher for older adults living in nursing homes.

Personality disorders categorized according to the types of behaviors include:

•   Paranoid
•   Schizoid
•   Schizotypal
•   Antisocial
•   Borderline
•   Histrionic
•   Narcissistic
•   Avoidant
•   Dependent
•   Obsessive-compulsive
•   Passive-aggressive
•   Depressive

It is important to realize that we may exhibit any or all of the symptoms of a personality disorder at different periods in our lives, however, a person with a true personality disorder is one who’s behaviors disrupt daily life to the point of being unable to function appropriately in society “consistently.”

Personality disorders are sometimes grouped into clusters that include:

•   Cluster A: paranoid, schizoid and schizotypal personality disorders; individuals with these conditions often appear odd or eccentric
•   Cluster B: antisocial, borderline, histrionic and narcissistic personality disorders; individuals with these disorders often appear dramatic, emotional, or erratic
•   Cluster C: avoidant, dependent and obsessive-compulsive personality disorders; individuals often appear anxious or fearful
