Having a personality disorder is different than having personality quirks. Personality quirks or eccentricities are considered normal; however, when certain dominant personality traits interfere with healthy psychological functioning, a personality disorder might be the cause. This next installment in Greenwood's series provides a complete overview of the 10 currently recognized personality disorders, as well as the myriad signs and symptoms that may lead to a diagnosis. Using the most recent scholarship and case studies, this volume aims to bring clarity to the topic of personality disorders, covering a wide range of topics from the history of assessing personality disorders to the ways in which a personality disorder may affect the family and friends of the patient.
