It's often said that a mental illness is not someone's fault, but it is their responsibility. This book, however, seems to absolve the elderly of both fault and responsibility. More than this, the authors refer to personality disorders by name only in the appendix, opting for the phrase "personality difference" instead, and even appear to doubt the existence of mental illnesses in the aforementioned appendix, putting the term in air quotes.
In the main part of the book, the authors frame eight different dimensions of difficult behavior and provide useful insights and possible explanations for each, but they place the onus for change solely on the adult children. It is the grown children--I refuse to use the authors' preferred cutesy portmanteau--who must navigate the minefields of their parents' behaviors, as this book fails to ask the parents to partake in diffusing their own mines. This, in my opinion, deprives the elderly of agency by denying them any responsibility for their actions.
While the authors occasionally acknowledge that older parents can be abusive, nowhere is it stared that they have the responsibility to change their behavior and stop harming those around them. This, my friends, enables abuse, and that is wrong, wrong, wrong, especially for authors who are practitioners in the mental and behavioral health fields.
Personality disorders may be among the most intransigent DSM disorders, and recovering from them is undoubtedly made harder the longer these characteristics and behavior patterns accrue, but they can be treated. Denying this prospect robs the elderly of experiencing beneficial connections and genuine happiness in the remaining years of life and perpetuates further abuse on the friends, family, and caretakers around them.
