RESUMEN

OBJECTIVES: Up to 70% individuals with bipolar disorder (BD) are lifetime tobacco smokers, a major modifiable risk factor for morbidity. However, quitting smoking is rarely proposed to individuals with BD, mainly because of fear of unfavorable metabolic or psychiatric changes. Evaluating the physical and mental impact of tobacco cessation is primordial. The aim of this study was to characterize the psychiatric and nonpsychiatric correlates of tobacco smoking status (never- vs. current vs. former smokers) in individuals with BD. METHODS: 3860 individuals with ascertained BD recruited in the network of Fondamental expert centers for BD between 2009 and 2020 were categorized into current, former, and never tobacco smokers. We compared the sociodemographic and clinical characteristics assessed by standard instruments (e.g., BD type, current symptoms load, and non-psychiatric morbidity-including anthropometric and biological data) of the three groups using multinomial regression logistic models. Corrections for multiple testing were applied. RESULTS: Current smokers had higher depression, anxiety, and impulsivity levels than former and never-smokers, and also higher risk of comorbid substance use disorders with a gradient from never to former to current smokers-suggesting shared liability. Current smokers were at higher risk to have a metabolic syndrome than never-smokers, although this was only evidenced in cases, who were not using antipsychotics. CONCLUSIONS: Tobacco smoking was associated with high morbidity level. Strikingly, as in the general population, quitting smoking seemed associated with their return to the never-smokers' levels. Our findings strongly highlight the need to spread strategies to treat tobacco addiction in the BD population.

RESUMEN

OBJECTIVES: We investigated the feasibility and acceptability of an integrated group therapy (called HABIT) for comorbid bipolar disorder (BD) and alcohol and substance use disorders (ASUD) (BD-ASUD), a disabling clinical presentation for which no specific treatment has been validated. The 14-session HABIT programme employs psychoeducation-oriented cognitive-behaviour therapy (CBT) followed by mindfulness-based relapse prevention (MBRP) therapy. METHOD: Potential group participants were recruited from adult clients with a DSM-IV diagnosis of BD and an ASUD who were referred by their treating clinician. Observer-rated changes in mood symptoms and ASUD, attendance rates and subjective feedback are reported. RESULTS: Eight of 12 clients referred to the programme initially agreed to join the group, six attended the first group session and five clients completed the programme. Group mean scores for mood symptoms improved over time, with slightly greater reductions in depression during the first module. About 50% of individuals showed clinically significant improvement (≥30% reduction) in alcohol and substance use. Attendance rates showed some variability between individuals and across sessions, but the average attendance rate of the group was marginally higher for the first module (86%) as compared with the second module (77%). Most clients reported high levels of general satisfaction with a group specifically targeted at individuals with BD-ASUD. CONCLUSION: This small pilot study suggests our intensive group therapy is acceptable and feasible. If findings are replicated, we may have identified a therapy that, for the first time, leads to improvement in both mood and substance use outcomes in clients with difficult-to-treat comorbid BD-ASUD. Copyright © 2016 John Wiley & Sons, Ltd. Key Practitioner Message Comorbidity between bipolar and alcohol and substance use disorders (BD-ASUD) is frequent and highly disabling; Therapeutic research on approaches that can simultaneously help BD and ASUD is lacking; Previous research highlights the need for integrated treatment of both conditions but showed improvements limited to either element of the comorbid disorder; This pilot study supports the feasibility and acceptability of an intensive, 14-session group therapy programme that integrates CBT and mindfulness approaches.

RESUMEN

BACKGROUND: Eating disorders (EDs) are liable to alter the disease course of bipolar disorder (BD). We explored the crossed clinical features between EDs and BD, particularly as a function of BD type (BD1 vs. BD2). METHODS: 2929 outpatients attending FondaMental Advanced Centers of Expertise were assessed for BD and lifetime EDs with a semi-structured interview, and their sociodemographic, dimensional and clinical data were collected according to a standardized procedure. For each ED type, bivariate analyses were used to investigate associations between these variables and the type of BD type followed by multinomial regressions with the variables associated with EDs and BDs after Bonferroni correction. RESULTS: Comorbid EDs were diagnosed in 478 (16.4 %) cases, and were more prevalent in patients with BD2 than in those with BD1 (20.6 % vs. 12.4 %, p < 0.001). Regression models showed no difference according to the subtype of bipolar disorder on the characteristics of patients with anorexia nervosa (AN), bulimia nervosa (BN) or binge eating disorder (BED). After multiple adjustments, the factors differentiating BD patients with versus without ED were primarily age, gender, body mass index, more affective lability and comorbidity with anxiety disorders. BD patients with BED also scored higher regarding childhood trauma. BD patients with AN also showed higher risk of past suicide attempts than those with BED. CONCLUSIONS: In a large sample of patients with BD, we found a high prevalence of lifetime EDs, especially for the BD2 type. EDs were associated with several severity indicators, but not with BD type-specific characteristics. This should prompt clinicians to carefully screen patients with BD for EDs, regardless of BD and ED types.

RESUMEN

OBJECTIVES: The comorbidity of alcohol use disorder (AUD) and bipolar disorder (BD) has been repeatedly associated with poorer clinical outcomes than BD without AUD. We aimed to extend these findings by focusing on the characteristics associated with the sequence of onset of BD and AUD. METHODS: 3,027 outpatients from the Fondamental Advanced Centres of Expertise were ascertained for BD-1, BD-2 and AUD diagnoses, including their respective ages at onset (AAOs, N =2,804). We selected the variables associated with both the presence and sequence of onset of comorbid AUD using bivariate analyses corrected for multiple testing to enter a binary regression model with the sequence of onset of BD and AUD as the dependent variable (AUD first - which also included 88 same-year onsets, vs. BD first). RESULTS: BD patients with comorbid AUD showed more severe clinical profile than those without. Compared to BD-AUD (N =269), AUD-BD (N =276) was independently associated with a higher AAO of BD (OR =1.1, p <0.001), increased prevalence of comorbid cannabis use disorder (OR =2.8, p <0.001) a higher number of (hypo)manic/mixed BD episodes per year of bipolar illness (OR =3, p <0.01). LIMITATIONS: The transversal design prevents from drawing causal conclusions. CONCLUSION: Increased severity of BD with AUD compared to BD alone did not differ according to the sequence of onset. A few differences, though, could be used to better monitor the trajectory of patients showing either one of these disorders.

RESUMEN

The "orbitofrontal" and "cingulate" frontostriatal loops and the mesolimbic dopaminergic system that modulates their function have been implicated in theory of mind (ToM). Parkinson's disease (PD) provides a model for assessing their role in humans. Results of the handful of previous studies of ToM in PD providing preliminary evidence of impairment remain controversial, mainly because the patients included in these studies were not accurately described, making it difficult to determine whether their ToM deficits were due to general cognitive deterioration or to a more specific dopaminergic deficit. The aim of our study was therefore to re-examine previous results highlighting ToM in PD and to explore the involvement of the dopaminergic pathways in ToM. ToM was investigated in 17 newly diagnosed PD patients (early PD group), 27 PD patients in the advanced stages of the disease (advanced PD group) and 26 healthy matched controls (HC), using two ToM tasks: a visual one, which is thought to reflect the "affective" ToM subcomponent ("Reading the Mind in the Eyes"), and a verbal one, which is thought to reflect both the "affective" and the "cognitive" ToM subcomponents (faux pas recognition). Furthermore, the early PD group was studied in two conditions: with and without dopamine replacement therapy (DRT). We failed to find any significant difference in ToM between the early PD patients and the HC group. Furthermore, there was no difference between the early PD patients in the medicated and unmedicated conditions. Conversely, the advanced PD patients scored poorly on the intention attribution question ("cognitive" ToM score) in the faux pas recognition task. The present results suggest that the deficit in ToM only occurs in the more advanced stages of the disease. In addition, our results would appear to indicate that these advanced PD patients present "cognitive" ToM impairment rather than global ("cognitive" and "affective") ToM impairment. In other words, the ToM deficit would appear to be present in PD patients where the degenerative process has spread beyond the dopaminergic pathways, but not in early PD patients where neuronal loss is thought to be restricted to the nigrostriatal and mesolimbic dopaminergic systems. In conclusion, our results suggest that the dopaminergic pathways are not involved in ToM.

RESUMEN

Behavioural disturbances such as disorders of mood, apathy or indifference are often observed in Parkinson's disease (PD) patients with chronic high frequency deep brain stimulation of subthalamic nucleus (STN DBS). Neuropsychological modifications causing these adverse events induced by STN DBS remain unknown, even if limbic disturbances are hypothesised. The limbic system supports neural circuits processing emotional information. The aim of this work is to evaluate changes of emotional recognition in PD patients induced by STN DBS. Thirty PD patients were assessed using a computerised paradigm of recognition of emotional facial expressions [Ekman, P., & Friesen, W. V. (1976). Pictures of facial affect. Palo Alto, CA: Consulting Psychologists Press], 15 before STN DBS and 15 after. The two patients groups were compared to a group of 15 healthy control subjects. One series of 55 pictures of emotional facial expressions was presented to each patient. Patients had to classify the pictures according to seven basic emotions (happiness, sadness, fear, surprise, disgust, anger and no emotion). The intact ability to percept faces was firstly assured using the Benton Recognition Test. Recognition of fear expressions was significantly and selectively reduced in the post-operative group in comparison to both pre-operative and control groups. Our results demonstrate for the first time a selective reduction of recognition of facial expressions of fear by STN DBS. This impairment could be the first neuropsychological marker of a more general limbic dysfunction, thought to be responsible for the behavioural disorders reported after STN DBS.

RESUMEN

Semantic dementia patients seem to have better knowledge of information linked to the self. More specifically, despite having severe semantic impairment, these patients show that they have more general information about the people they know personally by direct experience than they do about other individuals they know indirectly. However, the role of direct personal experience remains debated because of confounding factors such as frequency, recency of exposure, and affective relevance. We performed an exploratory study comparing the performance of five semantic dementia patients with that of 10 matched healthy controls on the recognition (familiarity judgment) and identification (biographic information recall) of personally familiar names vs. famous names. As expected, intergroup comparisons indicated a semantic breakdown in semantic dementia patients as compared with healthy controls. Moreover, unlike healthy controls, the semantic dementia patients recognized and identified personally familiar names better than they did famous names. This pattern of results suggests that direct personal experience indeed plays a specific role in the relative preservation of person-specific semantic meaning in semantic dementia. We discuss the role of direct personal experience on the preservation of semantic knowledge and the potential neurophysiological mechanisms underlying these processes.

RESUMEN

Subjective emotional experience is thought to rely on a large cortical-subcortical network including orbitofrontal and cingulate frontostriatal circuits together with the mesolimbic dopaminergic system that modulates their activity. Parkinson's disease (PD) provides a model for exploring this issue. By using an original emotion induction procedure, the present study examined to what extent subjective experience of emotion of PD patients at different stages of the disease was modulated by emotion in the same way as healthy individuals. A battery of film excerpts was used to elicit different emotional feelings (happiness, anger, fear, sadness, disgust, and neutral) in 15 newly diagnosed PD patients, 18 patients with advanced PD and 15 matched controls. The newly diagnosed patients were examined in two conditions: "on" and "off" dopaminergic medication. Participants reported the intensity of their emotional feelings on a scale consisting of 10 emotional categories. Results indicated that PD patients at different stages of the disease did not significantly differ from the controls in the self-reported emotional experience to the presented film excerpts. Moreover, analyses conducted within the newly diagnosed PD group (on-dopa vs. off-dopa conditions) indicated that the patients' emotional reactivity to the presented film excerpts was not significantly modulated by dopaminergic medication. These results thus question the possible role of dopaminergic pathways in subjective emotional experience, at least in this sample and in the context of emotion induction.

RESUMEN

Bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in Parkinson's disease (PD) can produce emotional disorders that have been linked to disturbance of the STN's limbic territory. The aim of this study was to confirm the impairment of the recognition of facial emotions (RFE) induced by STN DBS, not only ruling out the effect of the disease's natural progression in relation to the effect of DBS, but also assessing the influence of modifications in dopamine replacement therapy (DRT) following STN DBS. RFE was investigated in 24 PD patients who underwent STN DBS and 20 PD patients treated with apomorphine. They were assessed 3 months before and after treatment. The 2 patient groups were compared with a group of 30 healthy matched controls. The results showed that RFE for negative emotions (fear and sadness) was impaired in only the STN DBS group in the posttreatment condition and was unrelated to DRT. Results confirm the selective reduction of RFE induced by STN DBS, due neither to the disease's natural progression nor to modifications in DRT.

RESUMEN

A number of studies have reported impaired facial emotion recognition following subthalamic nucleus (STN) stimulation in Parkinson's disease (PD), and have related these changes to a limbic dysfunction induced by STN stimulation. The present study examined the effect of STN stimulation in PD patients on a specific component of emotion, namely the subjective experience of emotion. Thirteen post-operative PD patients, 13 pre-operative PD patients matched on clinical and neuropsychological characteristics, and 16 controls matched on age and education, were administered a validated battery of film excerpts known to primarily induce specific emotional feelings (anger, happiness, sadness, fear, disgust, and neutral), and self-rated the intensity of their emotional feelings on a discrete emotions questionnaire. The post-operative group showed a significant lower level of differentiation between the target feeling (i.e., the more likely to be reported) and non-target feelings for the film excerpts intended to induce "sadness" and "fear" respectively, as compared with the pre-operative and healthy control groups. Moreover, the post-operative group reported significantly less intense feelings of fear, anxiety and disgust for the excerpt intended to induce "fear" as compared with the pre-operative and the control groups, while no significant difference was observed between the pre-operative and control groups. Finally, the post-operative group reported significantly less intense feelings of sadness and anxiety during the excerpt intended to induce "sadness" as compared to the control group, although the differences between the pre- and post-operative groups and between the pre-operative and the control groups did not reach significance. Our study suggests that STN stimulation affects the subjective experience of emotion, thus providing a preliminary account of the modulation induced by STN stimulation of a distributed neuronal network underlying the subjective experience of emotion, although the exact contribution of the STN within such network remains to be specified.
