Charles Sanislow, associate professor of psychology, associate professor of neuroscience and behavior, is the co-author of an article titled “Interactions of Borderline Personality Disorder and Anxiety Disorders Over 10 Years,” published in the June issue of The Journal of Clinical Psychiatry.
This report examines the relationship of borderline personality disorders (BPD), as defined by the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th edition), to anxiety disorders using data on the reciprocal effects of improvement or worsening of BPD and anxiety disorders over the course of 10 years.
Sanislow and his colleagues prospectively assessed borderline patients with DSM-IV–defined co-occurring generalized anxiety disorder, panic disorder with agoraphobia, panic disorder without agoraphobia, social phobia, obsessive-compulsive disorder, and post traumatic stress disorder (PTSD) annually between 1997 and 2009. They used proportional hazards regression analyses to assess the effects of monthly improvement or worsening of BPD and anxiety disorders on each other’s remission and relapse the following month.
The study suggests that BPD negatively affects the course of general anxiety disorder, social phobia, and PTSD. In contrast, the anxiety disorders, aside from PTSD, had little effect on BPD course. For general anxiety disorder and social phobia, whose course BPD unidirectionally influences, the researchers suggest prioritizing treatment for BPD, whereas BPD should be treated concurrently with panic disorders, obsessive compulsive disorder, or PTSD.
