Te role of neuropsychiatric testing in psychiatric disorders is becoming more prominent. Neuropsychological measures that are similar across symptom domains and phenomena such as suicidality may help clinicians guide treatment and tailor therapies to the patient in the most efective way possible. We report the case of a 16-year-old girl who presented with bizarre, intrusive suicidal thoughts in the setting of OCD and MDD. Tis case is unusual in that we have accurate neuropsychological determination of our patient’s language and executive function defcits, and we propose a link between them and her expression of suicidality in the context of OCD and MDD. 1. Introduction In recent years, increasing focus is being turned towards defning patterns of neuropsychological dysfunction that are associated with specifc mental illness and specifc symp- tom clusters, including bipolar disorder, attention-defcit hyperactivity disorder, posttraumatic stress disorder, and schizophrenia [1–5]. Tis is largely due to a shif towards investigating brain structure and function underlying psy- chiatric disorders [6]. An example of this is the attempt to defne the neuropsychological attributes of people who attempt suicide. In adults, it has been found that suicidal ideation may result from dysfunctional frontal lobe executive decision-making [7]. Additionally, previous studies have also found that reduced verbal fuency is more common in suicide attempters than a comparable control group [8]. In addition to defning phenomena such as suicidal- ity, fnding neuropsychological measures that are similar across various disorders is of interest. For instance, exec- utive dysfunction is considered to be a state-dependent feature of major depressive disorder (MDD), a state or trait- dependent feature of obsessive-compulsive disorder (OCD), and a possible endophenotype for suicidality. However, the feld continues to lack a clear consensus on what these neuropsychiatric “signatures” consist of, especially in the less- studied pediatric psychiatric population, nor has the utility of these been established. For example, there is mixed literature regarding executive function in children with OCD. Beers et al. found that recently diagnosed children with OCD did not perform worse than healthy controls on neuropsychological testing [9]. Tis fnding was replicated by Abramovitch et al., who found that pediatric patients with OCD do not have signifcant neuropsychiatric performance defcits [10]. It has been postulated that children with disruptive behavior disorders may have poorer receptive, pragmatic, and expressive language skills [11]. Tis has been shown in attention-defcit hyperactivity disorder and other disruptive behavior disorders, in the pediatric population [12–14]. Tis has been shown less consistently in OCD and other disorders [15]. We present a pediatric patient with comorbid MDD and OCD with intrusive suicidal thoughts, who had measurable defcits in executive function and language fuency on neu- ropsychological testing. We believe that this is a timely report of a complex patient that highlights the neuropsychiatric correlates of various psychiatric symptoms and how this can inform treatment. 2.
