[This article prints out to about 12 pages.] Clinical corner Welcome to the first case presentation in the Clinical corner. This new offering from the Journal of Gambling Issues focuses on difficult situations that clinicians face when dealing with individuals suffering from pathological gambling. Sample composite cases will be presented to illustrate important points in conceptualizing how concurrent mental health factors interplay with the symptoms of pathological gambling. In some cases, the focus will be on a clinical condition, such as attention deficit hyperactivity disorder, or a therapeutic approach, such as mindfulness therapy. We invite readers to e-mail the editor (Phil_Lange@camh.net) to suggest future topics or to submit a clinical case for publication. The case below can be used as a template for submissions. All cases and materials presented in this section are peer reviewed. The case of the sleepless slot-machine supplicant: Bipolar disorder and pathological gambling
Bipolar disordersBipolar disorder (BP), previously known as manic-depressive illness, is a brain disorder that causes unusual shifts in a person's mood, energy, and ability to function. The prevalence rate is ~1.2%, e.g., three million adults in North America alone. The condition usually develops in late adolescence or early adulthood, but there are variant forms that begin in early childhood or later in life (Hales, Yudofsky, & Talbott, 1999). The symptoms are often not recognized ("just a wild guy/gal"), and people may suffer for years before the disorder is properly diagnosed and treated. They are often misdiagnosed as suffering from attention deficit hyperactivity disorder (ADHD), substance use disorders (SUD), and personality disorders (PD) such as borderline personality disorder (BPD) (Hirschfeld, 2001). In addition, conditions such as substance use, trauma (and resultant post-traumatic stress disorders (PTSD)), and mood disorders often coexist with people suffering from BP (Hales, Yudofsky, & Talbott, 1999). Bipolar disorder is a chronic illness that must be carefully managed throughout a person's life. There is no single cause for the condition and scientists speculate that a genetic basis combines with multifactorial vulnerabilities for the condition to manifest. Brain imaging tests have shown slight abnormalities in only some people with the condition and this supports the contention that BP represents a heterogeneous group of conditions (Soares, Mann, 1997). People with the condition may alternate between "manic episodes" (ME) and "major depressive episodes" (MDE). This is called "Bipolar I." Some people have only mild forms of mania—i.e., they manifest symptoms, but these are not severe enough to interfere with their functioning in life. Such manifestations are called "hypomanic episodes"; having them with alternating episodes of MDE is classified as "Bipolar II." Then there are people who manifest sub-clinical depressive episodes with hypomanic episodes, and this is called "cyclothymia." People who have at least four episodes (manic or depressive) in a year are classified as "rapid cycling." In fact, the normal course of the illness is that the frequency and intensity of episodes increase as time goes on. As this occurs, sometimes people can develop "mixed" episodes where they have symptoms of mania and depression simultaneously (e.g., they are both full of energy and suicidal) (American Psychiatric Association Diagnostic and Statistical Manual-IV-TR, 2000). Some episodes are so intense that people can develop psychotic features (i.e., hallucinations and delusions) or even catatonic features (abnormal movement states) during the episode's course. Sometimes episodes can be triggered by the stress of childbirth and arise in the postpartum period as well (APA DSM-IV-TR, 2000). The classic DSM-IV-TR symptoms and signs of a manic episode are listed in Table 1 and of a major depressive episode in Table 2
"Mimicry" of bipolar disorder by pathological gamblingInterestingly, according to the DSM IV-TR, one of the exclusion criteria for making the diagnosis of pathological gambling (PG) (see Table 3) is that the behaviours are not "better accounted for by a Manic Episode" (i.e., the gambling is only a small manifestation in the overall plethora of behaviours being manifested by someone in the throes of mania). Another thing to consider is that pathological gambling often co-occurs with other mental health and addiction issues. According to recent studies, BP is not very common compared to ADHD, SUD, and PD (Specker, et al., 1996; Petry, 2000). As well, behaviours (and their consequences) arising from PG can "mimic" other mental health issues, e.g., staying up all night to indulge in gambling, committing illegal acts such as stealing for money to gamble, spending their money only on gambling, emotional reaction to losses, dealing with relationships that are impacted by the gambling, and other problems. Often this may lead to depressive symptoms and, for those vulnerable, a major depressive episode. When gambling problems are treated usually many "psychiatric" symptoms vanish as well. If the symptoms do not resolve, or they get worse, then it becomes clear that there is a co-occurring/underlying psychiatric condition to be dealt with. So, what are the possibilities in this case? Possibility 1. Gambling behaviours in the context of bipolar disorderIf this were the case, we would expect Ms. S to have behaviours consistent with mania beyond just gambling. Gambling would most likely be merely one of the pleasurable activities someone would pursue while "high"—e.g., sex, spending sprees on all sorts of items, recreational drug use, running up telephone bills. The gambling would be just part of the many goal-directed activities engaged in, combined with poor judgment. Ms. S would demonstrate a grandiosity not just about her skills as a "great gambler" but about a great number of other things as well. You would also expect Ms. S to be in an energized state, needing little sleep for at least a week whether she was in the casino or not. Pressured speech (rapid, continuous, hard to interrupt) and flights of ideas (rapid shifting between usually related thoughts) occur in a manic state and not in pathological gambling. Similarly, a person does not develop psychotic symptoms if she is only engaging in pathological gambling! The clinician needs to get an understanding of the person's behaviours, signs, and symptoms inside and outside the gambling context. Possibility 2. Pathological gambling disorder aloneHow can this condition end up mimicking bipolar disorder? As mentioned already, people may be "driven" to gamble by many factors, but often they are releasing various neurochemicals (which give them pleasure and energy) during the act of gambling. This is why people can stay up for long periods of time—but eventually "crash" into exhaustion. They usually can't go a full week of being energized like someone in a manic state. Also, the "spending spree" is like in other addictions—the money is going into the pursuit of their gambling and very little else. This is not really a spending spree, then, but just part of the typical behaviour of pathological gambling. The gambler's affects and moods can be variable but are usually reactive to situations, e.g., feeling joyous while playing, ecstatic when winning, anxious when losing, depressed when in debt. In fact, one criterion for pathological gambling is "becoming restless and irritable" (see Table 3) when trying to cut down the behaviour. These shifting moods are not sustained abnormal mood states as described above in bipolar disorder. However, someone under enough stress and with the right amount of genetic vulnerability could develop a major depressive episode. The clinician needs to look at all mental health issues and behaviours and see if they always manifest within or due to the gambling behaviours, or are occurring outside of them as well. If the former, the behaviours can all be explained purely by a pathological gambling disorder. Possibility 3. Combined bipolar and pathological gambling disordersOf course, there is the possibility that both are occurring at the same time. There are a few ways this could look, including:
The key again is taking a careful longitudinal history of the different symptoms to see how they match up temporally. Possibility 4. None of the aboveAlthough it is beyond the scope of this article to go into in detail, bipolar disorder diagnoses are sometimes misdiagnoses of ADHD, BPD, SUD, and trauma-related conditions. Medical conditions such as hyperthyroidism can create equivalent manic behaviours. In Ms. S’s case above, there seems to be no history of learning problems or difficulties at school or attention problems (although this makes ADHD merely unlikely, but does not rule it out), and no overt trauma history (although emotional trauma may have occurred in her upbringing). Self-reported history and urine toxicology screen are negative (although, for example, cocaine can be undetectable a few days after use unless you use the proper lab tests), and her thyroid levels are normal. For simplicity in this article, let us go along with the working hypothesis that all these possibilities have been ruled out for now (although a good clinician always keeps fall-back hypotheses!). What do we need to know?So, to get the proper context to understand what is going on, the clinician needs to know at least the following:
The case revisitedBased on the information on the case, and assuming there are no underlying issues of ADHD, trauma, or addiction, etc., most of Ms. S's behaviours can be explained by the pathological gambling condition alone. There are likely some interpersonal issues that predate the gambling problem and may have originally led her to use gambling as a self-soothing, maladaptive coping mechanism, but further history would be required to solidify this theory. Although she is currently suffering from some mild depression, it does not appear to be a major depressive episode. Thus the medication she is taking may be unneeded. Cognitive behavioural therapy (CBT) can address gambling and depressive cognitions simultaneously. If the mood symptoms remain or worsen, then one can consider re-examining the situation to see if Ms. S has developed a MDE and could benefit from combined CBT and/or medication treatment. Final thoughtsContext is key. Symptoms don't exist in a vacuum. It often takes time to truly unravel a diagnosis, especially when many conditions have overlapping symptoms. Being misdiagnosed with bipolar disorder when instead the condition is pathological gambling has serious implications:
