Opposed effects of hyperthymic and cyclothymic temperament in substance use disorder (heroin- or alcohol-dependent patients)

The role of affective temperaments as a factor of vulnerability to seasonal affective disorder

BACKGROUND

Growing evidence suggests the relevance of affective temperaments in the development of mood disorders. This study aims to assess their potential role as a vulnerability factor for seasonal affective disorder (SAD) and subsyndromal SAD (S-SAD) in a sample of young individuals without a history of clinical diagnosis.

METHODS

Eight hundred and forty-six university students were enrolled in a cross-sectional study. Participants were evaluated for exclusion and inclusion criteria and divided into Control, S-SAD, and SAD groups. They filled out two self-administered questionnaires to assess the degree of seasonality problems and the predominant type of affective temperaments, the Seasonal Pattern Assessment Questionnaire (SPAQ), and the Temperament Evaluation Instrument of Memphis, Pisa, Paris, and San Diego-Auto-questionnaire version scale (briefTEMPS-M version). We conducted a multinomial logistic regression model to explore the relationship between affective temperaments and seasonality.

RESULTS

Our results evidenced that cyclothymic [χ2 (2) = 33.486, p < 0.001] and anxious [χ2 (2) = 86.991, p < 0.001] temperaments were significant predictors in the model, suggesting that individuals with cyclothymic and anxious temperaments are at increased risk of developing SAD, due to heightened seasonal changes in mood and behavior. In contrast, people with hyperthymic temperament appear less susceptible to experiencing seasonal problems.

LIMITATIONS

The homogeneity of the sample; only retrospective self-reported data were considered; measures of temperament and seasonality were simultaneously assessed.

CONCLUSIONS

Understanding which affective temperaments may constitute a potential predisposing factor for vulnerability to seasonal changes can aid in better assessing SAD and predicting its outcome.

Synthesising 30 years of clinical experience and scientific insight on affective temperaments in psychiatric disorders: State of the art

The concept of affective temperament has been extensively discussed throughout the history of psychopathology and represents a cornerstone in the study of mood disorders. This review aims to trace the evolution of the concept of affective temperaments (ATs) from Kraepelin's seminal work to the present day. In the 1980s, Akiskal redefined Kraepelin's concept of affective temperaments (ATs) by integrating the five recognized ATs into the broader framework of the soft bipolar spectrum. This conceptualization viewed ATs as non-pathological predispositions underlying psychiatric disorders, particularly mood disorders. Epidemiological and clinical studies have validated the existence of the five ATs. Furthermore, evidence suggests that ATs may serve as precursors to various psychiatric disorders and influence clinical dimensions such as disease course, psychopathology, and treatment adherence. Additionally, ATs appear to play a significant role in moderating phenomena such as suicide risk and stress coping. Incorporating an evaluation of temperamental bases of disorders into the multidimensional psychiatric diagnostic process could enhance treatment optimization and prognosis estimation.

Emotion dysregulation and affective temperaments in opioid use disorder: a 1-year follow-up study

BACKGROUND

Opioid use disorder (OUD) remains a significant public health challenge with high recurrence rates and varied long-term outcomes. Affective temperament and emotion regulation have been identified as influencing addictive behaviors and treatment outcomes in OUD. However, limited research has explored their association with reversion over an extended period.

OBJECTIVES

The EDATOUD (Emotion Dysregulation and Affective Temperaments in Opioid Use Disorder) study aimed to evaluate the effects of affective temperament and emotion regulation characteristics on recurrence over a 1-year follow-up period. The study aimed to compare the baseline characteristics of patients who achieved remission versus those who did not and identify potential predictors of recurrence risk.

METHODS

The study included 63 patients with OUD who were assessed monthly for return-to-use through self-report, psychiatric examination, and urine analysis. Sociodemographic data, affective temperament, difficulties in emotion regulation, anxiety, and depression were measured at baseline. Statistical analyses were performed to compare the recurrent and remission groups and determine the predictive value of these clinical features on recurrence.

RESULTS

Within the one-year, 77.8% of patients returned to use. Affective temperament characteristics did not differ between the groups. However, the recurrent group patients exhibited significantly more difficulties in emotion regulation.

CONCLUSIONS

Difficulties in emotion regulation are associated with an increased risk of recurrence in patients with OUD. Understanding these factors can inform the development of tailored treatment strategies to improve long-term outcomes. Further research is needed to explore additional factors contributing to reversion and enhance intervention and support systems for sustained recovery in OUD.

Affective neuroscience personality traits in opioid use disorder patients: The relationship with earlier onset of substance use, the severity of addiction, and motivational factors to quit opiate use

INTRODUCTION

This study aims to explore the relationship between affective personality traits and opioid use disorder (OUD), including factors such as motivation to quit, addiction severity, and age of onset of drug use.

METHODS

This study included 141 patients with opioid addiction (OAP) and 160 age- and sex-matched healthy controls (HC). OAP were interviewed and diagnosed according to DSM-5 criteria. HC were screened for past or current drug use. Participants completed sociodemographic forms and the Affective Neuroscience Personality Scale (ANPS), and the OAP group also completed the Addiction Profile Index (API).

RESULTS

SEEK, PLAY, and SADNESS were identified as different affective personality traits between OAP and HC groups. Addiction severity was positively correlated with SADNESS and ANGER, while the age of onset of drug use was correlated with ANGER. Risk factors for OA include family history of substance abuse, low education, and low PLAY scores, whereas risk factors for earlier substance use onset are childhood trauma and high ANGER scores.

CONCLUSIONS

This study highlights the importance of understanding affective personality traits in OUD. These findings may deepen our understanding of the underlying mechanisms of OUD. The identification of these affective systems may have implications for the development of personalized prevention and treatment strategies.

Using machine learning algorithms and techniques for defining the impact of affective temperament types, content search and activities on the internet on the development of problematic internet use in adolescents' population

Background

By using algorithms and Machine Learning - ML techniques, the aim of this research was to determine the impact of the following factors on the development of Problematic Internet Use (PIU): sociodemographic factors, the intensity of using the Internet, different contents accessed on the Internet by adolescents, adolescents' online activities, life habits and different affective temperament types.

Methods

Sample included 2,113 adolescents. The following instruments were used: questionnaire about: socio-demographic characteristics, intensity of the Internet use, content categories and online activities on the Internet; Facebook (FB) usage and life habits; The Internet Use Disorder Scale (IUDS). Based on their scores on the scale, subjects were divided into two groups - with or without PIU; Temperament Evaluation of Memphis, Pisa, Paris, and San Diego scale for adolescents (A-TEMPS-A).

Results

Various ML classification models on our data set were trained. Binary classification models were created (class-label attribute was PIU value). Models hyperparameters were optimized using grid search method and models were validated using k-fold cross-validation technique. Random forest was the model with the best overall results and the time spent on FB and the cyclothymic temperament were variables of highest importance for these model. We also applied the ML techniques Lasso and ElasticNet. The three most important variables for the development of PIU with both techniques were: cyclothymic temperament, the longer use of the Internet and the desire to use the Internet more than at present time. Group of variables having a protective effect (regarding the prevention of the development of PIU) was found with both techniques. The three most important were: achievement, search for contents related to art and culture and hyperthymic temperament. Next, 34 important variables that explain 0.76% of variance were detected using the genetic algorithms. Finally, the binary classification model (with or without PIU) with the best characteristics was trained using artificial neural network.

Conclusion

Variables related to the temporal determinants of Internet usage, cyclothymic temperament, the desire for increased Internet usage, anxious and irritable temperament, on line gaming, pornography, and some variables related to FB usage consistently appear as important variables for the development of PIU.

Profiles and the impact of affective temperaments on alcohol use disorder: a cross-sectional study

AIMS

This study aimed to explore the profiles and impact of affective temperaments, together with social and clinical backgrounds, including affective symptoms, in patients with alcohol use disorder (AUD).

METHODS

This study included 314 low-risk drinkers and 257 patients with AUD. To assess affective temperament, we used the short version of the temperament evaluation of Memphis, Pisa, Paris, and San Diego. To evaluate depressive and mixed symptoms, the quick inventory of depressive symptomatology self-report Japanese version and 12-item questionnaire for the quantitative assessment of the depressive mixed state were used. We compared the profiles of affective temperaments as well as social and clinical backgrounds, including affective symptoms, between the two groups and further performed logistic regression analyses to explore the factors contributing to AUD.

RESULTS

Our analysis showed higher cyclothymic, hyperthymic, and irritable temperament scores and lower depressive temperament scores in patients with AUD than that in nonclinical drinkers. Regarding other social and clinical backgrounds, patients with AUD were less educated and employed and more experienced depressive and mixed symptoms. Logistic regression analysis identified hyperthymic temperament as a positive contributor and depressive temperament as a negative contributor to AUD.

CONCLUSIONS

Our findings indicated potential bipolarity in patients with AUD, as manifested by a more hyperthymic temperament in contrast to less depressive temperament. Despite their self-perceived adaptive temperament profiles, patients showed poorer social outcomes and more affective symptoms. This gap may be partly explained by a lack of insight unique to AUD psychology, which potentially disturbs problem recognition.

Identifying different patterns of emotion dysregulation in adult ADHD

BACKGROUND

Emotion dysregulation (ED) is a core intrinsic feature of adult presenting Attention Deficit Hyperactivity Disorder (ADHD). However, the clinical expressions of ED are diverse and several questionnaires have been used to measure ED in adults with ADHD. Thus, to date, the characteristics of ED in adult ADHD remain poorly defined. The objective of this study is to identify the different patterns of ED in adults with ADHD.

METHODS

A large sample of 460 newly diagnosed adults with ADHD were recruited. Patients completed a total of 20 self-reported questionnaires. Measures consisted in the several facets of ED, but also other clinical features of adult ADHD such as racing thoughts. A factor analysis with the principal component extraction method was performed to define the symptomatic clusters. A mono-dimensional clustering was then conducted to assess whether participants presented or not with each symptomatic cluster.

RESULTS

The factor analysis yielded a 5 factor-solution, including "emotional instability", "impulsivity", "overactivation", "inattention/disorganization" and "sleep problems". ED was part of two out of five clusters and concerned 67.52% of our sample. Among those patients, the combined ADHD presentation was the most prevalent. Emotional instability and impulsivity were significantly predicted by childhood maltreatment. The ED and the "sleep problems" factors contributed significantly to the patients' functional impairment.

CONCLUSIONS

ED in ADHD is characterized along emotional instability and emotional impulsivity, and significantly contributes to functional impairment. However, beyond impairing symptoms, adult ADHD may also be characterized by functional strengths such as creativity.

Could Temperamental Features Modulate Participation in Clinical Trials?

The prodromal stages of Alzheimer's disease (AD) are the primary focus of research aimed at slowing disease progression. This study explores the influence of affective temperament on the motivation of people with mild cognitive impairment (MCI) and subjective cognitive decline (SCD) to participate in clinical trials. One hundred four subjects with MCI and SCD were screened for participation in pharmacological and non-pharmacological trials. Affective temperament was assessed based on the Temperament Evaluation of the Memphis, Pisa, Paris and San Diego (TEMPS) scale. Demographic variables and temperament subscales scores were compared between MCI and SCD patients and among patients participating in the pharmacological trial, the non-pharmacological trial and refusing participation. Twenty-one subjects consented to participate in the pharmacological trial, seventy consented to the non-pharmacological trial and thirteen refused to participate in any trial. Patients with SCD had greater education and more depressive temperamental traits than those with MCI. While older age, higher education and anxious temperament were negatively associated with participation in the pharmacological trial, irritable temperamental positively predicted pharmacological trial participation. In conclusion, temperamental features may affect the willingness of patients with MCI and SCD to take part in clinical trials and, especially, the choice to participate in pharmacological studies.

Emotion Dysregulation and Affective Temperaments in Opioid Use Disorder: the preliminary results of a prospective study

BACKGROUND

Substance use disorder is a growing health problem all over the world. The coexistence of substance misuse, affective temperaments, and emotion dysregulation has not been studied sufficiently.

OBJECTIVE

The present study aimed to evaluate the role of affective temperaments and emotion dysregulation on substance use disorder. The Emotion Dysregulation and Affective Temperaments in Opioid Use Disorder study was designed observational. This paper presents only the baseline assessments of the patient and control groups. One-year remission rates of the patients' group will be reported elsewhere after 1-year follow-up.

METHODS

Sixty-seven patients with opioid use disorder and 68 healthy controls enrolled. All participants were administered to The Structured Clinical Interview for DSM-5, Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire, Difficulties in Emotion Regulation Scale, Beck Anxiety Inventory, and Beck Depression Inventory.

RESULTS

Patients with opioid use disorder had higher scores from all temperamental scales and showed higher difficulties on emotion regulation than the control group. Even controlling the confounding effects of anxiety and depression levels, dysthymic and anxious temperament scores were found correlated with the emotion dysregulation score in the patient group.

CONCLUSIONS

The emotional traits (i.e., affective temperaments) and emotion regulation abilities play a crucial role in substance use disorder. While managing substance use disorder, being aware of affective temperament characteristics and/or interventions to improve emotion regulation skills may be helpful.

Affective temperaments and obesity: Is there an association with binge eating episodes and multiple weight cycling?

BACKGROUND

affective temperaments have been so far understudied in the field of obesity. Therefore, we aimed to assess affective temperaments in outpatients with obesity reporting symptoms of binge eating (BE) and multiple weight cycling (MWC) and to investigate the likelihood of an association between affective temperaments and risk of both conditions.

METHODS

A total of 300 individuals with obesity seeking treatment at the Obesity Unit of an academic hospital were asked to complete self-report measures of affective temperaments, BE, depressive and anxiety symptoms, and quality of life.

RESULTS

Even in the absence of full-blown mental disorders, symptoms of anxiety and depression emerged in the sample; 197 individuals (65.6%) reported BE and 162 (54%) MWC. The most frequent affective temperament was the depressive one. Depression symptoms and cyclothymic scores (directly), and age and hyperthymic score (inversely) were significantly associated with BE risk, while being an active smoker (directly) and hyperthymic score (inversely) were significantly associated with MWC risk, after controlling for confounders in a multiple logistic regression.

LIMITATIONS

sample size was small, the study was limited to a single center, no formal definition of weight cycling exists and MWC was self-reported.

CONCLUSIONS

A substantial number of outpatients with obesity reported BE and MWC notwithstanding the absence of a formal psychiatric diagnosis. Cyclothymic scores were positively associated with BE while the hyperthymic temperament showed a protective effect on both BE and MWC. These findings suggest the need for multidisciplinary treatments for people with obesity enhancing research on temperament-based psychological interventions.

Early parent-child interactions and substance use disorder: An attachment perspective on a biopsychosocial entanglement

This review aims to elucidate environmental and genetic factors, as well as their epigenetic and neuroendocrine moderators, that may underlie the association between early childhood experiences and Substance Use Disorders (SUD), through the lens of parental attachment. Here we review those attachment-related studies that examined the monoaminergic systems, the hypothalamic pituitary adrenal stress response system, the oxytoninergic system, and the endogenous opioid system from a genetic, epigenetic, and neuroendocrine perspective. Overall, the selected studies point to a moderating effect of insecure attachment between genetic vulnerability and SUD, reasonably through epigenetic modifications. Preliminary evidence suggests that vulnerability to SUDs is related with hypo-methylation (e.g. hyper-expression) of high-risk polymorphisms on the monoaminergic and hypothalamic pituitary adrenal system and hyper-methylation (e.g. hypo-expressions) of protective polymorphisms on the opioid and oxytocin system. These epigenetic modifications may induce a cascade of neuroendocrine changes contributing to the subclinical and behavioural manifestations that precede the clinical onset of SUD. Protective and supportive parenting could hence represent a key therapeutic target to prevent addiction and moderate insecure attachment.

Comparison of Emotional Dysregulation Features in Cyclothymia and Adult ADHD

Background and Objectives: Emotional dysregulation is central to the problem of the overlap between attention-deficit/hyperactivity disorder (ADHD) and cyclothymia. The aim of the study was to evaluate comorbidity rates between ADHD and cyclothymic disorder and to explore demographic and clinical differences among the groups, focusing on affective temperament and emotional dysregulation. Materials and Methods: One hundred sixty-five outpatients attending the Second Psychiatry Unit at the Santa Chiara University Hospital (Pisa) were consecutively recruited: 80 were diagnosed with ADHD, 60 with cyclothymic disorder, and 25 with both conditions. Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-M) and the 40-item version of Reactivity, Intensity, Polarity, and Stability questionnaire (RI-PoSt-40) were administered. Results: Cyclothymic patients were more frequently female and older with respect to the ADHD groups. Both comorbid and non-comorbid ADHD patients showed significantly lower educational attainment and more frequently had substance use disorders. Panic disorder was common in non-comorbid cyclothymic patients, who showed significantly higher rates of familial panic disorder, major depressive disorder and suicide attempts in comparison with patients only diagnosed with ADHD. Cyclothymic patients without ADHD were also characterized by fewer hyperthymic temperamental traits, higher depressive and anxious dispositions, and a greater negative emotionality. No significant differences among groups were observed for cyclothymic temperament and overall negative emotional dysregulation, but comorbid patients with both conditions scored the highest in these subscales. This group also showed significantly higher affective instability with respect to ADHD patients without cyclothymia and was less frequently diagnosed with bipolar disorder type II than patients from both the other groups. Conclusions: ADHD and cyclothymia often co-occur and show similar levels of emotional dysregulation. However, cyclothymic patients may be more prone to negative emotionality in clinical settings. Subjects with “sunny” cyclothymic features might escape the attention of clinicians unless ADHD is present.

Developmental trajectories in psychiatric disorders: does substance/alcohol use moderate the effects of affective temperaments as moderators of age at onset? A study in post-acute, hospitalized patients with psychotic or DSM-5 bipolar or major depressive disorders

BACKGROUND

Age-at-onset (AAO) affects psychiatric disorder outcome; substance (SUDs) or alcohol use disorders (AUDs) may influence their onset. Affective temperaments may affect early AAO and drug-use proneness. Objectives: To investigate whether SUD/AUD moderated temperamental effects in determining AAO of mental disorders. Methods: We included 300 post-acute inpatients with schizophrenia-spectrum and other psychotic (SSOPDs), major depressive (MDD) or bipolar (BD) disorders (168 men; mean age, 40.63 years ± 11.82 men, 43.21 years ± 12.69 women) with (N = 110) or without (N = 190) SUD/AUD. Patients completed cross-sectionally TEMPS-A. We carried moderation analysis with each regression-significant TEMPS temperament as independent variable, SUD/AUD presence/absence as dichotomous moderator, and AAO as dependent variable. Significance was set at p < 0.05. Results: AAO was lower in patients with SUD/AUD diagnosis than in patients without (23.74 ± 10.09 vs. 27.73 ± 10.35, respectively, p = 0.001, η2 = 0.034). SUD/AUD patients scored higher on the hyperthymic (10.22 ± 4.08, p < 0.001, η2 = 0.069) and irritable (8.26 ± 4.69, p < 0.01, η2 = 0.026) temperaments than nonSUD/AUD patients. Moderation analysis showed only direct effects of irritable (β = -0.55, p < 0.005) and hyperthymic (β = -0.95, p < 0.001) temperaments on AAO and no significant SUD/AUD and interaction effects. Limitations. Cross-sectional design. Conclusions: When irritable and hyperthymic traits prevail over other temperaments, AAO is earlier in SSOPDs, MDD, and BD. SUD/AUD presence/absence does not moderate the relationship between temperament and AAO.

Affective Temperaments and Illness Severity in Patients with Bipolar Disorder

Background and objectives: Bipolar disorder (BD) is one of the most burdensome psychiatric illnesses, being associated with a negative long-term outcome and the highest suicide rate. Although affective temperaments can impact on BD long-term outcome, their role remains poorly investigated. The aims of the present study are to describe the clinical characteristics of patients with BD more frequently associated with the different affective temperaments and to assess the relation between affective temperaments and severity of clinical picture in a sample of patients with BD. Materials and Methods: A total of 199 patients have been recruited in the outpatients units of two university sites. Patients’ psychiatric symptoms, affective temperaments, and quality of life were investigated through validated assessment instruments. Results: Predominant cyclothymic and irritable temperaments are associated to higher number of relapses, poorer quality of life, higher rates of aggressive behaviors, and suicide attempts. Conversely, the predominant hyperthymic disposition was a protective factor for several outcome measures, including relapse rate, severity of anxiety, depressive and manic symptoms, suicidality, and earlier age at onset. One limitation of the present study is that the recruitment took place in two university sites; therefore, our findings cannot be fully generalized to the whole community of BD patients. Other limitations are the lack of a control group and the cross-sectional design of the study. Conclusions: The early identification of affective temperaments can help clinicians to identify those BD patients who are more likely to show a poor long-term outcome. An early screening of affective temperaments can be useful to develop targeted integrated pharmacological and psychosocial interventions.

Relationship between affective temperament and major depressive disorder in older adults: A case-control study

BACKGROUND

In clinical practice it is often challenging to determine whether mood disturbances should be considered a state or trait characteristics. This study is important to understand the influence of temperaments in the diagnosis of depression. The objective of the present study was to compare the frequency of three types of affective temperament (dysthymia, hyperthymia and cyclothymia) among older adults with major depression compared to non-psychiatric control patients.

METHODS

A case-control study comparing 50 patients with major depression aged 65 years or above with a comparison group of 100 non-psychiatric controls. Affective temperaments were assessed using the TEMPS-A questionnaire. The 17-item Hamilton Depression Rating Scale and the Young mania Rating Scale were used for the assessment of symptoms of depression and mania, respectively.

RESULTS

In the sample 80% had an affective temperament, most commonly hyperthymia (67.3%). In depressive patients 48% had criteria for hyperthymic temperament against 77% of the controls (OR= 0.3, 95%CI 0.1-0.7). 38.8% of these patients presented cyclothymic temperament, whereas among controls, 12% fulfilled criteria (OR= 2.9, 95%CI 1.1-7.2).

LIMITATIONS

The sample was relatively small, and their educational level was very low.

CONCLUSION

A cyclothymic temperament may predict major depression unlike hyperthymia. Whether the effectiveness of mood stabilizers in unipolar disorder is moderated by a cyclothymic temperament and should be explored in future randomized controlled trials.

Affective Temperament Traits and Age-Predicted Recreational Cannabis Use in Medical Students: A Cross-Sectional Study

The use of cannabis among college students is increasing. Cannabis abuse has been proposed to be associated with personality dimensions. However, there are currently no known studies on the relationship of temperament traits and recreational cannabis use among college students. This is a cross-sectional study that investigated 328 students at a Podiatric Medical College. We evaluated the association between temperament and recreational cannabis use by the students. Temperament was investigated using the Memphis, Pisa, Paris and San Diego Auto- Questionnaire (TEMPS-A (short version)). Additionally, we assessed demographics variables and perceived stress in the context of cannabis use, and analyzed the findings using logistic regression. The prevalence of recreational cannabis use was 8.45%. Recreational cannabis use among these students was highly associated with irritable and cyclothymic temperament traits. There was no association between recreational cannabis use and perceived stress, and demographic variables or other substance use. Furthermore, logistic regression analysis indicated that higher scores in cyclothymic or irritable temperament traits are significant predictors for recreational cannabis use. Our study has identified key temperament traits, with a strong association with recreational use of cannabis of the studied student population. Our findings are useful in designing screening and educational strategies directed towards increasing the wellbeing of medical students.

The link between bipolarity and substance use: A controlled clinic based study

OBJECTIVES

Because of high rates of co-occurrence, common familial risk, and phenotypic similarities, we conjectured that substance use and bipolar disorder might have a common substrate of origin in bipolarity and that they might lie on a continuum of bipolarity. Thus it was aimed to investigate the association between bipolarity and substance use through a controlled, clinic based study.

METHODS

Cross sectional assessment and comparison of bipolarity as trait in four groups, namely the substance use disorder (SUD), bipolar disorder (BPAD), dual diagnosis (DD), and the healthy control (HC) groups. Bipolar spectrum diagnostic scale (BSDS) was used. The quality of life in these four groups was also assessed using WHOQOL-Bref scale.

RESULTS

The mean Bipolar spectrum diagnostic scale (BSDS) score in SUD was 11.0 ± 5.3 which was more than that of HC (6.2 ± 3.9) and lesser than that in BPAD (18.4 ± 4.2) and DD (20.6 ± 3.6). Differences among all four groups were statistically significant. SUD group was found to have significantly higher score than healthy control. The BSDS score of DD and BPAD groups were higher than those of SUD but the difference between BPAD and DD was non-significant.

DISCUSSION

The results showed a potential association between substance dependence and bipolarity. Mood dysregulation appears to be the link between the two. The gradient of bipolarity detected by BSDS screener suggests a continuum model between substance use and bipolar disorder. However, this is a clinic based study and only male patients have been taken for study.

Association between Cyclothymic Affective Temperament and Age of Onset of Hypertension

Affective temperaments represent a biologically stable core of emotional reactivity and have previously been associated with hypertension and arterial stiffening. The age, when hypertension is initiated, is influenced by different factors, but the role of personality traits in this regard is not clarified yet. Our aim was to study the association between affective temperaments and the age at onset of hypertension. In this cross-sectional study, 353 patients were included. After the evaluation of history, patients completed the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire. We used linear regression analysis to identify predictors of the age of onset of hypertension in the whole cohort and in male and female subpopulations. The independent predictors of the age at onset of hypertension were male sex (B = −4.57 (95% CI = −1.40 to −7.74)), smoking (B = −4.31 (−7.41 to −1.22)), and positive family history (B = −6.84 (−10.22 to −3.45)). In women, cyclothymic temperament score was an independent predictor of the initiation of hypertension (B = −0.83 (−1.54 to −0.12)), while this association was absent in men. Besides traditional factors, cyclothymic affective temperament might contribute to the earlier initiation of hypertension in women.

Affective temperaments in Lebanese people with substance use disorder

PURPOSE

To examine these temperaments among patients with substance use disorder (SUD) in the Lebanese population.

DESIGN

Case-control.

METHODS

Fifty-seven controls and 57 patients with SUD were enrolled between April and September 2017.

RESULTS

A significantly higher mean of depressive, irritable, and anxious temperaments was found in addicted patients as compared with the nonaddicts. However, the results of the multivariate analysis showed that anxious, hyperthymic, irritable temperaments would significantly increase the odds of addiction in participants (ORa = 25.20, 1.057, 1.168, 1.241, and 1.275). Cyclothymic temperament would significantly decrease the odds of addiction in participants (ORa = 0.817). Furthermore, suicidality was associated with depressive, anxious, and irritable temperaments.

PRACTICE IMPLICATIONS

Hyperthymic, irritable, and anxious temperaments were the main temperaments found in patients with SUD in Lebanon.

What we have learned from the Methadone Maintenance Treatment of Dual Disorder Heroin Use Disorder patients

Mental Disorders and Heroin Use Disorder (HUD) often co-occur and constitute correlated risk factors that the authors believe are best considered from a unitary perspective. In this article we review and discuss data collected by the V.P. Dole Research Group in Dual Disorder (V.P. Dole DD-RG) patients according to the following six discussion points: (1) Treatment of personality disorders during Methadone Maintenance Treatment (MMT); (2) Treatment of Mood Disorders during MMT; (3) Treatment of Anxiety Disorders during MMT; (4) Treatment of Psychotic Disorders during MMT; (5) Treatment of violence during MMT; (6) Treatment of Alcohol Use Disorder (AUD) during MMT. In treating Mood Disorder in HUD patients, we must bear in mind the interactions (potentiation and side effects) between psychopharmacology, used substances and agonist opioid medications; the use of psychiatric medications as an anti-craving drug, and the possible use of agonist and antagonist opioid medications in treating the other mental disorders. In treating chronic psychosis in HUD patients, we must consider the potentiation and side effects of antipsychotic drugs consequent on HUD treatment, worsening addiction hypophoria and inducing a more severe reward deficiency syndrome (RDS) in hypophoric patients. Violence and AUD during MMT can benefit from adequate dosages of methadone and co-medication with Sodium gamma-hydroxybutyrate (GHB). The experience of our V.P. Dole DD-RG suggests the following: (a) DD is the new paradigm in neuroscience in deepening our understanding of mental health; (b) To successfully treat DD patients a double competence is needed; (c) In managing DD patients priority must be given to Substance Use Disorder (SUD) treatment (stabilizing patients); (d) Antidepressant use is ancillary to SUD treatment; antipsychotic use must be restricted to acute phases; mood stabilizers must be preferred; any use of Benzodiazepines (BDZs) must be avoided.
