Personality Disorders and Older Adults 
Diagnosis, Assessment, and Treatment

The older adult population is booming in the United State and
across the globe. With this boom comes an increase in the number of
older adults who experience psychological disorders. Current
estimates suggest that about 20% of older persons are diagnosable
with a mental disorder: Personality disorders are among the most
poorly understood, challenging, and frustrating of these disorders
among older adults. This book is designed to provide scholarly and
scientifically-based guidance about the diagnosis, assessment, and
treatment of personality disorders to health professionals, mental
health professionals, and senior service professionals who
encounter personality-disordered or ‘difficult’ older adults.
