Affective temperament profiles and clinical correlates in patients with epilepsy: a link from mood disorders

Point prevalence of depression in persons with active epilepsy and impact of methodological moderators: A systematic review and meta-analysis

OBJECTIVES

The aim of this study was to determine the pooled prevalence of depression in persons with epilepsy and assess the methodological moderators affecting the prevalence estimates.

METHODS

Five electronic databases PubMed, The Cochrane Library, EMBASE, WHO Global Index Medicus, and Clinicaltrial.gov were searched for studies reporting prevalence of depression in PWE ≥ 18 years of age in any setting.

RESULTS

Out of 13,873 studies, after deduplication and screening, 56 studies with 10,527 PWE met the eligibility criteria. The overall pooled prevalence of depression in PWE was 32% (95%confidence interval [CI] 28-35%) and significant heterogeneity (Chi-square = 1171.53, p = 0.00; τ² = 0.02; I² = 94.36%). Prevalence has doubled in the recent years (16% in 2000-2005 vs. 35% in 2016-2020), was higher in Asia than in Europe (coefficient 0.899, 95%CI: 0.809-0.999; p = 0.049). Among assessment methods, prevalence was highest in HAM-D scale (54%, 95%CI: 27-82%) and lowest in MINI (22%, 95%CI: 19-26%). Sensitivity analysis also corroborated findings when MINI was excluded (35%, 95%CI: 31-38%).

CONCLUSIONS

A significant proportion of PWE have depression. Though there is substantial heterogeneity due to various methodological moderators, it is unlikely to affect the routine screening of PWE for depression. Use of a screening tool should be based on ease of administration, and cutoff selection should ensure identification of minimal depression as well.

Suicidal ideation, hopelessness, and affective temperament in patients with blepharospasm

OBJECTIVE

The aim of this study was to investigate the relationship between suicidal ideation and neurological, psychological, and psychiatric features in patients with blepharospasm (BSP).

METHODS

We enrolled 70 BSP patients and 80 control subjects. All participants underwent a psychiatric and psychometric evaluation: Structured Clinical Interview, Clinical Global Impression, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, Columbia-Suicide Severity Rating Scale, Beck Hopelessness Scale, Temperament Evaluation of Memphis, Pisa, San Diego Auto-questionnaire. BSP severity was assessed using the Blepharospasm Severity Rating Scale.

RESULTS

Suicidal ideation was reported in 18% of BSP patients and 6% had current suicidal ideation. 83% of BSP patients had severe hopelessness. BSP patients presented an increased sense of hopelessness (OR= 1.39, 95% CI = 1.13/1.70) and a pronounced depressive temperament (OR= 1.36, 95% CI = 1.12/1.65). Suicidal ideation in BSP patients correlated with psychiatric disorders (OR = 3.96, 95% CI = 1.23/12.74) and higher scores on the HAM-A (OR = 1.11, 95% CI = 1.02/1.20), HAM-D (OR = 1.18, 95% CI = 1.05/1.32), CGI (OR = 1.85, 95% CI = 1.18/2.90), TEMPS-A Cyclothymia (OR = 1.16, 95% CI = 1.02/1.31).

CONCLUSION

Our findings suggest the presence of suicidal ideation and severe hopelessness in BSP patients.KEY POINTSBSP patients as compared to controls more frequently reported the presence of a psychiatric disorder and more severe anxiety and depressive symptoms, psychopathology on the CGI, suicidal ideation, and hopelessness.BSP patients with prevalent cyclothymic temperament had more severe suicidal ideation, suggesting an increased suicide risk most likely due to difficulties in psychological adaptation to changing environments, including the neurological disease.A psychiatric assessment is recommended for patients with this condition, with possible referral to a suicide prevention centre.

Predictive factors of quality of life in temporal and extratemporal lobe epilepsy: association with affective temperament profiles and psychiatric comorbidities

BACKGROUND

Investigating predictive factors of reduced quality of life (QOL) of patients and their association with focal epilepsy can improve management and treatment strategies.

OBJECTIVE

This study aimed to investigate the relationship between affective temperaments, depression, anxiety, disease characteristics, and QOL and to explore the predictors of QOL in patients with temporal lobe epilepsy (TLE) and extratemporal lobe epilepsy (ETLE).

METHODS

A total of 50 patients with TLE, 51 patients with ETLE, and 70 controls were enrolled. Affective temperaments were evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A). QOL was assessed by the Short-Form Health Survey (SF-36). Beck Depression Inventory and Beck Anxiety Inventory were used to explore depression and anxiety severity, respectively.

RESULTS

Compared with the controls, patients with TLE and ETLE had significantly higher scores on all TEMPS-A scales, except on hyperthymic temperament. All the SF-36 subscale scores were lower in the TLE and ETLE groups. Linear regression analysis revealed that depressive symptoms, anxiety, depressive and irritable temperament, and seizure frequency were significant predictors of QOL in TLE. Patients with ETLE with temperamental disturbances, depressive symptoms, and polytherapy had a poorer QOL.

CONCLUSIONS

Affective temperaments, psychiatric disorders, and clinical factors may predict impaired QOL in patients with TLE and ETLE. Further studies are needed to identify predictors of QOL in various epilepsy subtypes.

Dysphoria and Irritability-Diagnostic Pitfalls in the Assessment of Interictal Dysphoric Disorder in Epilepsy

This article aims to review the concept of epilepsy-specific psychiatric disturbance, Interictal Dysphoric Disorder (IDD), focusing on issues related to its core symptoms and methodological pitfalls. In the psychiatric literature, an epilepsy-specific pleomorphic mood disorder has been long recognized and described as IDD, a condition characterized by eight symptoms, which are grouped into four labile depressive symptoms, two labile affective symptoms, and two specific symptoms. The existence of IDD is still a matter of debate because of several methodological issues. The main features of IDD, such as dysphoria and irritability, lack precise and clear definition. This review article explores the different definitions and approaches towards both terms described in the psychiatric literature and the rationale for modifying the diagnostic process of IDD.

Epilepsy at the intersection of disability, gender, and culture: A duoethnography

Epilepsy is a neurodevelopmental disorder that affects millions of adults and children. Several different types of seizures, ranging from generalized which affect both sides of the brain to focal seizures that are rooted in one location of the brain. In addition to the physical impact of epilepsy, there are many emotional and identity consequences of living with epilepsy. An area that is not yet explored is the impact of epilepsy on the lives of women of color. In this paper, we fill this gap by exploring the experiences of two women of color who have had epilepsy beginning in early childhood through motherhood. One of the women is Mexican-American and an early career faculty in social work. The other identifies as a Chinese immigrant doctoral student in disability studies. Together, these stories bring to the literature voices that have not been actively engaged by epilepsy research or academia. We use a duoethnographic approach in this work given that this method provides an opportunity to explore identity and intersectionality and juxtapose our narratives surrounding epilepsy. By applying disability critical race theory (DisCrit) to our narratives, we identified how fluctuating epileptic symptoms, gender, and culture, interact with the layers of our epileptic identities. Furthermore, we discuss how our experiences with epilepsy exposes the lack of accommodative efforts in both the healthcare and education systems for individuals with invisible neurodevelopmental disabilities. This duoethnography has important implications for engaging youth with epilepsy and other invisible disabilities. By showcasing our journey of "coming to terms" with epilepsy, our dialog provides insights into how to support youth in building a positive disability identity. Our experiences in academia set up a basis to discuss accommodations for students with epilepsy and other invisible disabilities.

A survey on doctors' cognition of depression in patients with epilepsy

OBJECTIVE

This survey aimed to assess doctors' cognition on depressive symptoms in patients with epilepsy in Shanghai China.

METHODS

Questionnaires were handed out to doctors who have taken part in the epilepsy care, covering those from all third-grade hospitals and several second-grade hospitals in Shanghai China. Respondents were asked to make choices for their demographic profiles, clinical practices, acquired knowledge of, and attitudes toward the comorbidity of epilepsy and depression.

RESULTS

A total of 282 questionnaires were collected from 16 hospitals in Shanghai China, of which 280 copies were included in the statistical analysis. Respondents were mainly less than 50 years (260, 92.8%), mostly residents and attendings (206, 73.6%), and mostly master and doctor's degrees (225, 80.3%). The ratio of epileptologists and nonepileptologists was 56 (20.1%):224 (79.9%). Compared to nonepileptologists and residents, epileptologists and doctors with higher professional titles were more likely to answer that they received a higher percentage of patients with the comorbidity of epilepsy and depression (≥30%), and they knew very well about the knowledge, and held the view that depression exacerbated seizures (p < .05). Surprisingly, most doctors including chief doctors and epileptologists answered that they had difficulties in prescribing antidepressants. Quite a few doctors from lower class hospitals even preferred to use tricyclic antidepressants for controlling depressive symptoms in patients with epilepsy.

SIGNIFICANCE

Doctors, especially younger doctors and nonepileptologists, need more training to get knowledge of the comorbidity of epilepsy and depression. However, the therapeutic methods for depressive symptoms in patients with epilepsy were still limited and in a challenge.

The relation of major depression, OCD, personality disorders and affective temperaments with Temporal lobe epilepsy

BACKGROUND

In patients with temporal lobe epilepsy (TLE), studies demonstrate frequent comorbidity with mood disorders, personality disorders (especially obsessive-compulsive disorder) and major depression, but there are conflicting findings. This study aimed to investigate psychiatric comorbidities and affective temperament among TLE patients and to explore the relationships between obsessive compulsive disorder, other personality disorders, major depression and affective temperament in order to clarify the mediator effect of TLE in these relationships.

METHODS

Thirty patients with TLE and 30 healthy volunteers were included. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), the Structured Clinical Interview for DSM III-R Axis II Disorders (SCID-II), Hamilton Anxiety (HAM-A) scale, Hamilton Depression (HAM-D) scale, Beck Suicidal Ideation Scale (BSSI) and Yale Brown Obsession Compulsion Scale (YBOCS) were applied and evaluated by a psychiatrist. Additionally, all individuals completed The Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A).

RESULTS

Patients with temporal lobe epilepsy had higher scores in TEMPS-A, HAM-A, HAM-D, YBOCS and BSSI. Major depression, obsessive compulsive disorder and dependent and antisocial personality disorders were prevalent in patients. With respect to affective temperaments, depressive, cyclothymic and anxious temperaments were associated with obsessive compulsive disorder comorbidity; whereas, depressive and anxious temperaments were found to be associated with major depression comorbidity in patients with TLE. Furthermore, cluster A and cluster C personality disorders were associated with affective temperaments in patients with TLE. Affective temperaments had no correlation with illness duration, seizure frequency, depression severity and suicidal thoughts, but obsessions and compulsions. Suicidal thoughts were associated with obsessions and compulsions.

CONCLUSION

Affective temperaments are core personality traits with biological background and they may provide a foundation for psychiatric disorders, especially mood disorders. Considering that TLE originates from abnormalities in brain circuitry, it may form a basis for psychiatric disorders. Therefore, psychiatric evaluation to determine comorbidities may be beneficial to increase the quality of life of patients with TLE.

The association between temperament features and childhood traumas in patients with juvenile myoclonic epilepsy

Background/aim

Epilepsy is a common chronic neurological problem that impairs daily activities, functionality, and quality of life. Childhood traumas (CTs) are known to be critical factors in the onset or development of many psychiatric and medical disorders. They also play a critical role in the development of temperament and personality. This study aimed to investigate the association between CTs and common temperament patterns and features seen in epilepsy patients.

Materials and methods

The study included 38 patients who were diagnosed with juvenile myoclonic epilepsy (JME) and volunteered to participate in the study. In addition to the sociodemographic form and questions on disease features, Structured Clinical Interview for DSM-IV Axis I Disorders, Temperament Evaluation of Memphis, Pisa, Paris and San Diego Questionnaire (TEMPS-A), Childhood Trauma Questionnaire (CTQ), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) were administered to all participants. In the present study, a cut-off value of 35 was used for the CTQ scale. The patients with CTQ scores lower than 35 (50%, n = 19, Group 1) and the patients with CTQ scores above 35 (50%, n = 19, Group 2) were compared.

Results

The comparison of TEMPS-A and its subscale scores in the JME patients in the groups with CTQ scores above or below a cut-off value detected significant differences between the groups in depressive and irritable temperament scores. The mean BDI scores were also different between the two groups. Furthermore, a significant positive correlation was detected between the disease duration, anxiety, and depression scores in the JME patients. A significant relationship was detected between the emotional neglect subscale score of the JME patients and the BDI scores. A significant positive correlation was found between the total disease duration, BDI, and BAI. Significant moderate-level relationships were found between the BDI score and irritable, depressive, cyclothymic, and anxious temperaments and between the BAI score and irritable, depressive, cyclothymic, and anxious temperaments.

Conclusion

Several temperamental features of JME patients are related to CTs. More depressive symptoms are seen in JME patients with higher disease durations.

Health-related quality of life in multiple sclerosis: temperament outweighs EDSS

BACKGROUND

The influence of personality on health-related quality of life in patients with multiple sclerosis has been the focus of previous studies showing that introversion and neuroticism were related with reduced health related quality of life. However, no data exist on the impact of temperament on quality of life in this patient group.

METHODS

Between April 2014 and March 2016 139 multiple sclerosis patients were recruited from a specialized outpatient clinic of the general hospital of Vienna. Health-related quality of life was measured by "The Multiple Sclerosis International Quality of Life Questionnaire (MusiQol)", temperament by "Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Questionnaire - Münster version" (briefTEMPS-M), and disability by the "Expanded disability status scale". All patients underwent a diagnostic psychiatric semi-structured interview (MINI).

RESULTS

Known predictors (like disease duration, EDSS, psychiatric co-morbidities, immunomodulatory treatments) explain the proportion of variation in the outcome of MusiQol global index score in 30.9% in multi-variable linear regression analysis. It increased respectively to 40.3, 42.5, and 45.8% if adding the depressive, cyclothymic, or hyperthymic temperament to the list of variables. An increase of depressive and cyclothymic temperament scores significantly reduced global index score of MusiQol (p = 0.005, p = 0.002, respectively), while the hyperthymic temperament significantly raised it (p < 0.001).

CONCLUSION

In MS patients, the depressive and cyclothymic temperament predict a lower and hyperthymic temperament an increased health-related quality of life, independent of current disability status, immunomodulatory treatments, and affective co-morbidities.

Suicide risk, temperament traits, and sleep quality in patients with refractory epilepsy

OBJECTIVES

The objective of the study was to access the suicide risk (SR) in patients with refractory epilepsy and its association with temperament and sleep quality.

METHODS

A total of 50 consecutive patients referred for epilepsy surgery evaluation in the Porto Alegre Epilepsy Surgery Program were included. All patients had a detailed neurologic and psychiatric evaluation, including video-electroencephalogram (VEEG), high-resolution magnetic ressonance imaging (MRI), and neuropsychologic assessment. In addition, structured questionnaires were applied: module C of the MINI-plus (International Neuropsychiatric Interview-Brazilian version 5.0.0), Affective and Emotional Composite Temperament Scale (AFECTS), and Pittsburgh Sleep Quality Index (PSQI).

RESULTS

Ten patients (20.0%) showed an increased SR. The most frequent location of the epileptic focus was in the temporal lobe (50%; n=25). Final diagnosis on VEEG comprised epilepsy in 74.0% (n=37), psychogenic nonepileptic seizures (PNES) in 8.0% (n=4), and both in 12%. Thirty patients (60.0%) received surgery indication. Mood disorders were the main psychiatric diagnosis, found in 19 subjects (70.4%), with major depressive disorder (MDD) encountered in 15 patients (55.6%). In the group, SR was more frequent in patients with sleep disorders (p=0.001) and elevated scores of high emotional sensitivity (p=0.003).

CONCLUSION

In this cohort of patients with highly refractory epilepsy, there was a significant association between SR, sleep disorders, and high emotional sensitivity. Careful evaluation of these factors should be performed in these patients to fully access SR.

Affective temperament profile in ankylosing spondylitis patients using TEMPS-A

[Purpose] This study aimed to compare the most common dominant affective temperaments in Ankylosing Spondylitis patients and investigate the relationship between the dominant affective temperaments and pain levels, disease activity, quality of life, current depression, and anxiety level in Ankylosing Spondylitis patients. [Subjects and Methods] Fifty-one patients diagnosed with axial spondiloartropathy and forty-two age- and gender-matched control subjects were included in this study. Disease duration, erythrocyte sedimentation rate, serum C-reactive protein, pain by the Visual Analog Scale, disease activity by the Bath Ankylosing Spondylitis Disease Activity Index, functional status by the Bath Ankylosing Spondylitis Functional Index; psychological status by the Beck Depression Inventory, Beck Anxiety Inventory and overall health assessment by the Ankylosing Spondylitis Quality of Life Scale were assessed in patients. The Turkish version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto Questionnaire was used to determine the dominant affective temperament. [Results] There was no statistical difference in the distribution of temperament subtypes between patients with Ankylosing Spondylitis and the controls. Depressive, anxious, and cyclothymic temperament scores were higher in patients with high values on the Bath Ankylosing Spondylitis Functional Index and Visual Analog Scale. There was a correlation between anxious subtypes of affective temperament scores and the value of Ankylosing Spondylitis Quality of Life Scale. Correlation analysis also found depressive, cyclothymic, irritable, and anxious temperament and psychiatric symptoms to be significantly related. [Conclusion] Affective temperament may contribute to symptoms of depression and anxiety in patients with Ankylosing Spondylitis and may increase disease activity and may reduce their quality of life.

The interictal dysphoric disorder of epilepsy: Legend or reality?

For a long time, the relationships between epilepsy and mood disorders captured the attention of clinicians and neuroscientists. The existence of a peculiar clinical presentation for mood disorders in epilepsy has been a matter of debate since the early reports of Kraepelin and Bleuler. The interictal dysphoric disorder (IDD) represents the modern reinterpretation of such early observations. This paper reviews current research on this topic discussing clinical implications, phenomenological observations, and directions for future research.

[Dysphoric disorders in epilepsy]

OBJECTIVE

to determine the differentiated clinical variants of dysphoric disorders in epilepsy based on their syndromal patterns, etiopathogenetic and dynamic characteristics.

MATERIAL AND METHODS

Eighty men (mean age 32.7 years, illness duration from 11 to 20 years) were examined using clinical/psychopathological methods. Data analysis was performed with Statistika-10 software.

RESULTS AND CONCLUSION

Dysphoric disorders in epilepsy were most frequent among affective disorders Paroxysmal, psychogenic and autochthonous dysphoric disorders were determined. Depending on the severity of one of the three axial affective components (anger, fear, melancholy): the explosive, phobic, depression, and moros-dysphoria were selected. According to the level of disorders, the dysphoric appearances were divided into simple, involving only affective symptoms, and complex, which contained, in addition to affective cerebroasthenic disorders, disorders of perception, thinking, consciousness, inclinations. Explosive psychogenic and paroxysmal dysphorias were most common. Psychogenic dysphoric reactions were most frequent in an isolated form in the clinical picture. Among combinations of dysphoric states, a combination of psychogenic and autochthonous dysphoric disorders occupied the leading place.

Affective temperaments in subjects with female-to-male gender dysphoria

BACKGROUND

Males and females have different temperaments. In individuals with gender dysphoria (GD) there is marked incongruence between a person׳s expressed/experienced gender and their biological sex. The present study aimed to investigate the most common affective temperaments in individuals with female-to-male (FtM) GD.

METHODS

We performed a prospective and comparative study investigating affective temperaments in subjects with FtM GD. Eighty subjects with FtM GD and 68 female controls were enrolled. The Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) was completed by all participants.

RESULTS

TEMPS-A scores were significantly higher in subjects with FtM GD for hyperthymic temperament (p≤0.001), whereas depressive (p≤0.001), anxious (p≤0.001), and cyclothymic (p=0.028) temperament scores were significantly higher in female controls.

LIMITATIONS

The study was limited by the lack of male-to-female subjects and male controls.

CONCLUSIONS

The results of our study indicate that individuals with FtM GD have significantly higher scores of hyperthymic temperament, measured by TEMPS-A. Biological basis underlying the development of gender identity independent from the biological sex might be related with affective temperaments.

The dilemma of treatments for epileptic patients with depression

Depression is a state of low mood and aversion to activity. It may occur due to existence of other mental or physical diseases or from the medications for those illnesses. It is one of the leading sources of disability. Among these physical diseases, epilepsy is widely recognized as one of the main causes of depression. Patients with epilepsy are at high risk of developing depressive symptoms, and the suicide rates in patients with epilepsy have been reported to be much higher than in the general population. However, due to fears of lowering seizure threshold and adverse drug interactions between antidepressants and antiepileptic drugs, physician are reluctant to place patients with epilepsy on antidepressant medication. As a result, the question has been raised that what the best managements should be used to treat epileptic patients with depression. In this review, the currently used medications for antidepressants and antiepileptic drugs were summarized by their working targets in order to establish appropriate pharmacological management of depression and epilepsy. Despite the complex relationship between epilepsy and depression, coadministration of antidepressants and AEDs can still be done safely and effectively under the conditions of good clinical management. The ideal antidepressants for people with epilepsy should be efficacious but with few adverse effects, which will not antagonize GABAergic mechanisms or interfere with plasma anticonvulsant concentrations.
