Does Substance Use Make Borderline Personality Disorder Symptoms Worse?
My outside HealthyPlace.com life sometimes requires that I read medical studies. Recently, I stumbled across a University of Mississippi Medical Center study on substance use and borderline personality disorder. Basically, the study asked if substance use disorders make borderline personality disorder (BPD) symptoms worse?
Common comorbidity: BPD and substance abuse
One of the symptoms of BPD, according to the Mayo Clinic, is "Impulsive and risky behavior, such as risky driving, unsafe sex, gambling sprees or illegal drug use". In other words, substance abuse is a common symptom of BPD. For example, I am a recovering alcoholic. The study estimates that 60 percent of people with BPD have a substance abuse problem.
However, not all people with BPD have a comorbid substance abuse disorder. There are nine criteria for a diagnosis of BPD, and to merit a diagnosis of BPD the person need meet only five or more of them. Substance abuse is simply one of those nine criteria.
But how does substance abuse affect BPD symptoms? Does it make them worse? The study's conclusion may surprise you.
Does substance abuse make BPD worse?
"There is compelling evidence that comorbid borderline personality disorder (BPD) negatively impact the clinical courses and outcomes of substance use disorders (SUD)," the study's abstract reads. "Conversely, there is little evidence that concurrent SUD exacerbates the clinical characteristics of BPD. " In other words, BPD can make substance abuse worse, but it is unknown whether substance abuse can make BPD worse.
"Female BPD patients without (BOR; n = 37) or with current substance dependence (BSUD; n = 19), and female non-BPD/SUD controls (CON; n = 48) were compared with respect to impulsivity, affective lability, affective intensity, externalizing behaviors, and self-harming/suicidal tendencies, taking into consideration their comorbid mood disorders, anxiety disorders, and antisocial personality disorder. Results indicated that both BOR and BSUD groups scored higher than CON in most of the measures, but BOR and BSUD failed to reveal significant group differences especially when the influence of comorbid psychopathology was removed. "
Translation: Women with BPD, regardless of whether or not they had a substance abuse disorder, scored higher than the control group in terms of impulsivity, emotional instability, emotional intensity, and self-injurious and suicidal behavior. However, when comorbid diagnoses were taken into consideration, there was no significant difference between women with BPD and a comorbid substance use disorder and women with BPD without a coormorbid substance abuse disorder.
Conclusion: "The overall pattern of findings remained identical even when comparing BPD patients with versus without the diagnosis of lifetime substance dependence. Our results do not support the notion that BPD individuals with SUD display more severe BPD features than individuals with BPD alone."
A word of warning
Before you break out the celebratory six pack, let me offer a word of warning. I disagree with the study's conclusion because that's not been my experience. When I drink, I'm a lot more likely to self-injure or do something else that I wouldn't do sober. I become a lot more impulsive and considerably more emotional. So in a sense, my alcoholism does make my BPD symptoms worse.
But this is an area that's difficult to study. People with BPD, regardless of whether or not they have a substance abuse diagnosis, often have several comorbid diagnoses that can make BPD symptoms worse. For example, it might be my PTSD and not my BPD that accounts for my conduct while drinking. Or it could be my schizoaffective disorder. We simply don't know because there's too many variables.
Also, as the study acknowledges, BPD makes substance abuse disorder symptoms worse. This in and of itself makes watching substance use a good idea.
More research is needed on comorbid BPD and substance abuse. But for now, BPD may account for the negative consequences of substance abuse.

I also don't agree with the study's conclusion. I don't have PTSD but I do have BPD which I think is the reason for my substance abuse. I have no problem abstaining from drugs and alcohol and can easily go weeks without drinking. However, when I do drink (even if it's just 2 beers or so) I get extremely "hyper", emotional and impulsive which ultimately leads to more drinking and drug abuse.
Many substances can bring on withdrawal-an effect caused by cessation or reduction in the amount of the substance used. Withdrawal can range from mild anxiety to seizures and hallucinations.Drug overdose may also cause death.^..',
