Alexithymia,temperament and character as predictors of psychopathology in patients with major depression

The study investigated the capacity of alexithymic personality features, in combination with temperament and character traits, age and gender, to predict psychopathological symptoms in patients with major depression. Consecutive patients (n = 339) were investigated using the Toronto Alexithymia Scale-20 (TAS-20), the Temperament and Character Inventory (TCI), the Symptom Checklist-90-R (SCL-90-R), and the Hamilton Depression and Anxiety Rating Scales (HDRS, HARS). The amount of variance in SCL-90-R subscales and Hamilton scales predicted by TAS-20, TCI, age and gender was calculated by linear regression analyses. The ‘difficulties identifying feeling’ facet of alexithymia appeared to be a significant predictor of all dimensions of psychopathology. Among TCI scales harm avoidance was the strongest predictor for somatization, phobic anxiety, and anxiety (SCL-90-R, HARS); low self-directedness was the strongest predictor for obsessionality, depression (SCL-90-R, HDRS), interpersonal sensitivity and psychoticism; and low cooperativeness was the strongest predictor for hostility and paranoia. In conclusion, many psychopathological symptoms in major depression are associated with difficulties in the identification of emotions. Relative to alexithymia, Cloninger's psychobiological model of personality could predict psychopathological symptoms in a distinct and meaningful manner. The TAS-20 and the TCI are useful questionnaires for a better understanding of the relationship between psychopathology and personality in major depression.     

Attachment style,relationship quality,and psychological distress in patients with psychogenic non-epileptic seizures versus epilepsy

ObjectivesPsychopathology levels are elevated in patients with psychogenic non-epileptic seizures (PNES) and those with epilepsy. However, patients with PNES report higher rates of trauma and neglect, poorer health-related quality of life (HRQoL), and an increased prevalence of insecure attachment. We examined to what extent attachment style and relationship quality with their main informal carer impact on levels of HRQoL, depression, and anxiety in patients with PNES versus those with epilepsy.MethodConsecutive patients with PNES (N = 23) and epilepsy (N = 72) completed questionnaires about attachment style, quality of their relationship with their main informal carer, seizure severity, HRQoL, depression, and anxiety.ResultsPatients with PNES reported higher levels of anxiety and depression and lower HRQoL than those with epilepsy. PNES: No significant correlations were found with HRQoL but depression correlated positively with attachment avoidance, attachment anxiety, and relationship conflict. Anxiety correlated positively with attachment avoidance, attachment anxiety, and relationship conflict, and negatively with relationship depth and support. Epilepsy: HRQoL correlated negatively with seizure severity, depression, anxiety, attachment avoidance, and attachment anxiety. Depression correlated positively with attachment avoidance, attachment anxiety, and relationship conflict. Anxiety correlated positively with seizure severity, attachment avoidance, and attachment anxiety. Correlations between measures of relationship quality and anxiety were stronger in patients with PNES versus those with epilepsy (zs = 2.66 to 2.97, ps < 0.004). Attachment style and relationship quality explained larger amounts of variance in depression (45%) and anxiety (60%) in the patients with PNES than those with epilepsy (16% and 13%).SignificanceLevels of anxiety and depression were higher in patients with PNES than those with epilepsy. Interpersonal problems were much more closely associated with anxiety and depression in patients with PNES than those with epilepsy. The findings support the use of therapeutic interventions for PNES focusing on attachment and relationship issues.     

Panic attack symptoms differentiate patients with epilepsy from those with psychogenic nonepileptic spells (PNES)

Psychogenic nonepileptic spells (PNES) are frequently challenging to differentiate from epileptic seizures. The experience of panic attack symptoms during an event may assist in distinguishing PNES from seizures secondary to epilepsy. A retrospective analysis of 354 patients diagnosed with PNES (N = 224) or with epilepsy (N = 130) investigated the thirteen Diagnostic and Statistical Manual—IV-Text Revision panic attack criteria endorsed by the two groups. We found a statistically higher mean number of symptoms reported by patients with PNES compared with those with epilepsy. In addition, the majority of the panic attack symptoms including heart palpitations, sweating, shortness of breath, choking feeling, chest discomfort, dizziness/unsteadiness, derealization or depersonalization, fear of dying, paresthesias, and chills or hot flashes were significantly more frequent in those with PNES. As patients with PNES frequently have poor clinical outcomes, treatment addressing the anxiety symptomatology may be beneficial.     

Which patients with epilepsy are at risk for psychogenic nonepileptic seizures (PNES)? A multicenter case–control study

ObjectiveWe sought to examine the clinical and electrographic differences between patients with combined epileptic (ES) and psychogenic nonepileptic seizures (PNES) and age- and gender-matched patients with ES-only and PNES-only.MethodsData from 138 patients (105 women [77%]), including 46 with PNES/ES (39 ± 12 years), 46 with PNES-only (39 ± 11 years), and 46 with ES-only (39 ± 11 years), were compared using logistic regression analysis after adjusting for clustering effect.ResultsIn the cohort with PNES/ES, ES antedated PNES in 28 patients (70%) and occurred simultaneously in 11 (27.5%), while PNES were the initial presentation in only 1 case (2.5%); disease duration was undetermined in 6. Compared with those with ES-only, patients with PNES/ES had higher depression and anxiety scores, shorter-duration electrographic seizures, less ES absence/staring semiology (all p ≤ 0.01), and more ES arising in the right hemisphere, both in isolation and in combination with contralateral brain regions (61% vs. 41%; p = 0.024, adjusted for anxiety and depression) and tended to have less ES arising in the left temporal lobe (13% vs. 28%; p = 0.054). Compared with those with PNES-only, patients with PNES/ES tended to show fewer right-hemibody PNES events (7% vs. 23%; p = 0.054) and more myoclonic semiology (10% vs. 2%; p = 0.073).ConclusionsRight-hemispheric electrographic seizures may be more common among patients with ES who develop comorbid PNES, in agreement with prior neurobiological studies on functional neurological disorders.     

Catastrophizing misinterpretations predict somatoform-related symptoms and new onsets of somatoform disorders

BackgroundSomatoform disorders are characterized by multiple recurring symptoms that resemble physical illnesses but defy medical explanation. Psychological models suggest that catastrophizing misinterpretations of harmless physical symptoms play a key role. However, the question of whether such biases predict somatoform-related symptoms and the onset of somatoform disorders has not been adressed. Hence, the aim of the present study was to further advance our understanding of the role of catastrophizing misinterpretations in somatoform disorders.MethodsIn the present study, we used data from the Dresden Predictor Study (N = 1538), in which an epidemiologic sample of young German women was tested at two time points approximately 17 months apart. Each participant completed a diagnostic interview, an interpretation questionnaire for somatoform and hypochondriacal symptoms, and three measures of such symptomatology: somatization subscale of the Symptom Checklist-90-Revised (SCL-90-R), Whiteley Index (WI), Body Sensations Questionnaire (BSQ).ResultsAt follow-up, 33 women were diagnosed with new onsets of lifetime somatoform disorder. Results showed that catastrophizing misinterpretations assessed at baseline were predictive of somatoform-related symptoms at follow-up, i.e., symptoms assessed with the WI and BSQ. Moreover, catastrophizing misinterpretations were predictive of new onsets of somatoform disorders, even after controlling for general threat-related misinterpretations and indices of somatoform symptoms (i.e., SCL-90-R and BSQ).ConclusionsThis is the first prospective, longitudinal study to demonstrate that catastrophizing misinterpretations have incremental validity as predictors of future somatoform-related symptomatology and somatoform disorders.     

Increased soluble interleukin-2 receptor levels are related to somatic but not to cognitive-affective features in major depression

Cell-mediated immune activation may play a role in the pathogenesis of depression as indicated by findings of increased soluble tumor necrosis factor receptor (sTNF-R) levels and meta-analytic evidence for elevated soluble interleukin-2 receptor (sIL-2R) concentrations. However, little research has been done on how these soluble cytokine receptors are differently related to specific features in patients with depression. We measured levels of the soluble cytokine receptors sIL-2R, sTNF-R1 and sTNF-R2 in 25 non-medicated patients with major depression (DSM-IV) and 22 healthy controls. Psychometric measures included cognitive-affective depressive symptoms, somatoform symptoms, somatic and cognitive dimensions of anxiety and current mood states. While patients with depression showed increased levels of sIL-2R (p < 0.01), differences in sTNF-R1 (p = 0.09) and sTNF-R2 (p = 0.08) marginally failed to reach significance. Increased concentrations of sIL-2R were related to somatic measures such as the severity of somatoform symptoms and somatic anxiety symptoms but not to cognitive-affective measures or current mood states. Our findings may suggest some specificity in the relationship between sIL-2R and symptom dimensions and highlight potential pathways by which T cell mediated immune activation may underpin somatic symptoms in depression.     

L’efficacité thérapeutique du Montage Composite Réceptif à visée Projective (MCR-P) contre la dépression en psychiatrie

ObjectivesThe Receptive Projective Composite Montage (RPCM) is a short-term therapy associating musicotherapy and clinical psychology in order to improve the psychiatric treatment of depression. This study aims at showing the therapeutic efficiency of the RPCM on depression and anxiety symptoms and on the in-patient's alexithymia level. Furthermore, this study explores the explanatory processes of the therapeutic effects in order to bring an additional dimension to this approach.MethodThe sample consists of 23 patients diagnosed with depression, aged between 27 and 73 (average age = 49.91 ± 10.47) who receive psychiatric treatment. Participants have been categorized into two experimental groups: the therapeutic group who received 3 sessions of RPCM (n = 13) and the control group who received psychiatric treatment only (n = 10). These two groups allowed us to achieve a test re-test method over three weeks with a comparative group. The evaluation tools are the Beck's Depression Inventory (BDI) for the evaluation of depression, the Hospital Anxiety and Depression Scale (HADS) for the anxiety level and the Toronto Alexithymia Scales-20 (TAS) for the alexithymia level.ResultsOver a three-week therapy with the RPCM, in-patients from the therapeutic group have a significantly lower level of depression, anxiety and alexithymia after therapeutic process (P = .002; P = .001 and P = .009 respectively). Moreover, depression scores of experimentals groups are significantly different during second evaluation (P = .006). Finally, therapeutic group depression and anxiety scores have a medium effect size (d = .5).Discussion and conclusionWith these results, the RPCM seem to be a tool with beneficial effects on the in-patient's symptomatology of depression. The RPCM can be used as a support technique in order to maximize the treatment of depression. We recommend using a minima three RPCM section at the start of internment by a trained therapist. More experimental and complementary studies are necessary to confirm these results.     

Deconstructing stigma in psychogenic nonepileptic seizures: An exploratory study

Psychogenic nonepileptic seizures (PNES) are classified as a mental disorder, the manifestations of which superficially resemble epileptic seizures.There is a notable lack of in-depth qualitative or quantitative studies investigating the stigma attached to PNES. The current study is an exploratory analysis into the nature of perceived stigma in those with PNES when compared with individuals with epilepsy. Individuals with epilepsy (n = 78) and PNES (n = 47) were recruited from a United Kingdom hospital or membership-led organizations for individuals living with seizures. Participants were asked to complete a series of questionnaires investigating health-related quality-of-life components (NEWQOL-6D), anxiety (GAD-7), depression (NDDI-E), seizure frequency and severity (LSSS-3), and illness perception (B-IPQ). Perceived stigma was measured using one question taken from the NEWQOL-6D. Individuals with PNES reported a greater level of perceived stigma than those with epilepsy (p = 0.04). Our results indicate that the risk of experiencing perceived stigma in PNES was 42% higher than the risk in epilepsy. In epilepsy, but not PNES, perceived stigma was significantly associated with seizure frequency, anxiety, depression, and many of the sequelae of the condition. In both conditions, self-control was associated with stigma (rho ≥ 0.34, p ≤ 0.01). This study was exploratory, and so definitive conclusions cannot be made; however, our findings suggest that the majority (87.2%) of individuals with PNES reported experiencing some degree of perceived stigma, the risk of which is greater than that in epilepsy. Further research is needed into the prevalence, nature, and consequences of stigma in PNES.     

Predictors of health-related quality of life in patients with epilepsy and psychogenic nonepileptic seizures

Epilepsy and psychogenic nonepileptic seizures (PNES) are associated with reduced health-related quality of life (HRQoL). The present study investigated the profile, relationship, and predictive power of illness perceptions, psychological distress (depression and anxiety), seizure activity, and demographic factors on HRQoL in these patient groups. Patients with epilepsy (n = 62) and PNES (n = 45) were recruited from a United Kingdom hospital and from membership-led organizations for individuals living with seizures. Patients completed a series of self-report questionnaires assessing: anxiety (GAD-7), depression (NDDI-E), illness perceptions (B-IPQ), HRQoL (NEWQOL-6D), and seizure frequency and severity (LSSS-3). Correlational and hierarchical multiple regression analyses were conducted. Patients with epilepsy reported higher HRQoL and scored lower on measures of depression and anxiety. Patients with PNES perceived their condition as more threatening overall. In both conditions, HRQoL was negatively correlated with more severe illness perceptions and psychological distress. In epilepsy and PNES, psychological distress (epilepsy: 27%; PNES: 24.8%) and illness perceptions (epilepsy: 23.1%; PNES: 23.3%) accounted for the largest amount of variance in HRQoL. Clinical factors were found not to be significant predictors, while demographic factors predicted HRQoL in epilepsy (12.6%), but not in PNES. Our findings support the notion that psychological factors are a stronger predictor of HRQoL in epilepsy and PNES than condition-related and demographic variables. Prior research suggests that anxiety and depression are key predictors of HRQoL; this study demonstrates that the relationship between illness perceptions and HRQoL is similarly close. These findings highlight the importance of addressing patients' beliefs about their condition.     

Prolonged exposure therapy for the treatment of patients diagnosed with psychogenic non-epileptic seizures (PNES) and post-traumatic stress disorder (PTSD)

ObjectiveAlthough there is general consensus that psychogenic non-epileptic seizures (PNES) are treated with psychotherapy, the effectiveness of most psychotherapeutic modalities remains understudied. In this treatment series of 16 patients dually diagnosed with PNES and post-traumatic stress disorder (PTSD), we evaluated the effect of prolonged exposure therapy (PE) on reduction of PNES. Secondary measures included Beck Depression Inventory (BDI-II) and Post-Traumatic Disorder Diagnostic Scale (PDS).MethodsSubjects diagnosed with video EEG-confirmed PNES and PTSD confirmed through neuropsychological testing and clinical interview were treated with traditional PE psychotherapy with certain modifications for the PNES. Treatment was conducted over the course of 12–15 weekly sessions. Seizure frequency was noted in each session by examining the patients' seizure logs, and mood and PTSD symptomatology was assessed at baseline and on the final session.ResultsEighteen subjects enrolled, and 16 (88.8%) completed the course of treatment. Thirteen of the 16 (81.25%) therapy completers reported no seizures by their final PE session, and the other three reported a decline in seizure frequency (Z = − 3.233, p = 0.001). Mean scores on scales of depression (M = − 13.56, SD = 12.27; t (15) = − 4.420, p < 0,001) and PTSD symptoms (M = − 17.1875, SD = 13.01; t (15) = − 5.281, p < 0.001) showed significant improvement from baseline to final session. Longitudinal seizure follow up in 14 patients revealed that gains made on the final session were maintained at follow-up (Z = − 1.069 p = 0.285).SignificanceProlonged exposure therapy for patients dually diagnosed with PNES and PTSD reduced the number of PNES and improved mood and post traumatic symptomatology. Follow-up revealed that gains made in seizure control on the last day of treatment were maintained over time.     

Prevalence of alexithymia in patients with psychogenic non-epileptic seizures and epileptic seizures and predictors in psychogenic non-epileptic seizures

ObjectiveThe first objective of this study was to determine the prevalence rate of alexithymia (dysregulation and unawareness of emotion) in patients with psychogenic non-epileptic seizures (PNESs) and epileptic seizures (ESs). The second objective was to identify the predictors of alexithymia in patients with PNESs.MethodsWe studied 66 consecutive patients with PNESs and 35 patients with ESs with the Toronto Alexithymia Scale-20. The prevalence of alexithymia was determined in both groups. In order to identify the risk factors of alexithymia in PNES, the Trauma Symptom Inventory-II (TSI-II), the MMPI 2-RF, a clinical history, and demographic variables were studied.ResultsOur study revealed a prevalence of alexithymia in PNES and ES of 36.9% and 28.6%, respectively (not a significant difference). Upon examining the group with PNES, we found a significant correlation between alexithymia and Anxious Arousal (r = .497, p < .000), Intrusive Experiences (r = .541, p < .000), Dissociation (r = .421, p < .001), and Defensive Avoidance (r = .444, p < .000) from the TSI-II. Minnesota Multiphasic Personality Inventory-2-RF RCd (r = .512, p < .000), RC1 (r = .346, p < .017), RC2 (r = .355, p < .017), RC3 (r = .467, p < .001), and EID (r = .567, p < .000) also correlated significantly with alexithymia. However, stepwise regression analysis only retained Intrusive Experiences and Defensive Avoidance from the TSI-II and the cynicism RC3 scale from the MMPI 2-RF.ConclusionSymptoms of psychological trauma and cynicism in patients diagnosed with PNESs were associated with alexithymia. These findings are encouraging, as they assist in better understanding the condition and in treatment design for this subset of patients.     

Stress coping strategies in patients with psychogenic non-epileptic seizures and how they relate to trauma symptoms,alexithymia, anger and mood

PurposeThe purpose of the present study was to assess stress coping strategies employed by patients with psychogenic non-epileptic seizures (PNES) and determine whether these approaches were associated with other psychopathological features. Ineffective stress coping strategies can have a variety of unhealthy consequences fueling psychopathology just as psychopathology can also have an impact on stress coping. Because of this, the study of stress coping has the potential to inform our understanding of the PNES condition and underscore a potential target for psychological treatment.MethodsEighty-two consecutive patients with PNES were studied using the Coping Inventory for Stressful Situations (CISS). The CISS is a self-rating coping strategies scale that has three main subscales (Task-Oriented, Emotion-Focused, and Avoidance-Oriented). Other psychological variables that were thought to potentially influence the chosen coping mechanisms including alexithymia, symptoms of post-traumatic stress disorder, anger expression and select scales from the Minnesota Multiphasic Personality Inventory 2-RF (MMPI 2-RF) were also evaluated.ResultsFifty patients (60.9%) endorsed using at least one coping strategy that was 1.5 standard deviations or more away from the normal adult mean. Over 30% of the participants endorsed using elevated Emotion-Focused coping strategies (T score ≥ 65), and just over 25% endorsed underusing Task-Oriented coping strategies (T score ≤ 35). Elevations in avoidance strategies were endorsed by only 15.9% of the respondents. ANOVA comparing T scores between the coping strategies was significant (F = 13.4, p = .0001) with a significantly lower Task-Oriented strategy than Emotion-Focused (p = .001) and Avoidance (p = .005) strategies.Patients with high scores of Emotion-Focused coping strategies also had significantly high scores on diverse psychopathology factors including elevations on depressive mood, intrusive experiences, anger state, and general anger scores. In contrast, those who used Task-Oriented strategies and who used Avoidance-Focused strategies had less psychopathology including low positive emotion scores (RC2).ConclusionNearly one-third of patients with PNES tended to use the less effective Emotion-Oriented coping strategies and one fourth reported underusing the more effective Task-focused strategies. Substantial differences were noted between coping strategies with a significantly lower Task-Oriented strategy than Emotion-Focused and Avoidance strategies. In addition, high Emotion-Focused coping was seen in patients with underlying psychological symptoms that were not observed in other coping strategies. This information supports the relevance of assessing stress coping in patients with PNES because it allows the identification of useful behavioral targets for the psychotherapist.     

Nocturnal masseter muscle activity is related to symptoms and somatization in temporomandibular disorders

ObjectiveTemporomandibular disorders (TMD) have often been related to sleep bruxism and elevated nocturnal masseter muscle activity (NMMA). However, previous studies have revealed controversial results, and the role of somatization, depression and anxiety has not been studied in this context. The aim of this study was to investigate the association between NMMA and pain intensity, TMD related symptoms, somatoform symptoms, depression, and anxiety in chronic TMD.MethodsThirty-six subjects with chronic painful TMD, 34 subjects with pain free bruxism, and 36 healthy controls recorded their nocturnal masseter muscle activity during three consecutive nights with portable devices. In addition, participants completed pain diaries and questionnaires. Diagnoses were established using the research diagnostic criteria for TMD.ResultsSubjects with chronic TMD reported a reduced general health state (p < .001), higher levels of somatoform symptoms (p < .001), depression (p < .05), and anxiety (p < .001) compared to control subjects with or without sleep bruxism. The amount of NMMA did not differ significantly between the groups. In subjects with TMD, pain intensity was not related to NMMA. However, higher NMMA was related to higher intensity of jaw related symptoms such as headache or tinnitus, and higher somatization in general.ConclusionChronic TMD is associated with elevated levels of psychopathology. These findings suggest a common link between NMMA, somatization, and symptom intensity in chronic TMD.     

Diagnostic implications of review-of-systems questionnaires to differentiate epileptic seizures from psychogenic seizures

ObjectiveEarly and accurate diagnosis of patients with psychogenic nonepileptic seizures (PNES) leads to appropriate treatment and improves long-term seizure prognosis. However, this is complicated by the need to record seizures to make a definitive diagnosis. Suspicion for PNES can be raised through knowledge that patients with PNES have increased somatic sensitivity and report more positive complaints on review-of-systems questionnaires (RoSQs) than patients with epileptic seizures. If the responses on the RoSQ can differentiate PNES from other seizure types, then these forms could be an early screening tool.MethodsOur dataset included all patients admitted from January 2006 to June 2016 for video-electroencephalography at UCLA. RoSQs prior to May 2015 were acquired through retrospective chart review (n = 405), whereas RoSQs from subsequent patients were acquired prospectively (n = 190). Controlling for sex and number of comorbidities, we used binomial regression to compare the total number of symptoms and the frequency of specific symptoms between five mutually exclusive groups of patients: epileptic seizures (ES), PNES, physiologic nonepileptic seizure-like events (PSLE), mixed PNES plus ES, and inconclusive monitoring. To determine the diagnostic utility of RoSQs to differentiate PNES only from ES only, we used multivariate logistic regression, controlling for sex and the number of medical comorbidities.ResultsOn average, patients with PNES or mixed PNES and ES reported more than twice as many symptoms than patients with isolated ES or PSLE (p < 0.001). The prospective accuracy to differentiate PNES from ES was not significantly higher than naïve assumption that all patients had ES (76% vs 70%, p > 0.1).DiscussionThis analysis of RoSQs confirms that patients with PNES with and without comorbid ES report more symptoms on a population level than patients with epilepsy or PSLE. While these differences help describe the population of patients with PNES, the consistency of RoSQ responses was neither accurate nor specific enough to be used solely as an early screening tool for PNES. Our results suggest that the RoSQ may help differentiate PNES from ES only when, based on other information, the pre-test probability of PNES is at least 50%.     

Does alexithymia expose to mental disorder symptoms in late adolescence? A 4-year follow-up study

ObjectiveTo investigate the possible causal link between alexithymia and the emergence of anxiety and depression symptoms, as well as alcohol consumption in a sample of late adolescents.MethodThe nonclinical sample comprised late adolescents (n= 315), including both females (n= 256) and males (n= 59). The follow-up period was 4 years, and at baseline, the mean age of the subjects was 19 years (range 17−21 years). Alexithymia was measured with the 20-item Toronto Alexithymia Scale (TAS-20), depression symptoms with the short form of the Beck Depression Inventory (RBDI), anxiety with the State-Trait Anxiety Inventory (STAI) and alcohol consumption with the Alcohol Use Disorders Identification Test (AUDIT). The three TAS-20 subscales were assessed separately. Linear and cumulative logistic regression analyses were used for the evaluation of associations, and the analyses were adjusted with the corresponding baseline scores.ResultsThe TAS-20 total and subscale scores did not predict the RBDI or AUDIT scores at follow-up. However, the TAS-20 subscale “difficulty identifying feelings” was significantly associated with both STAI-State (P= .007) and STAI-Trait (P= .004) scores at follow-up.ConclusionsAlexithymic features may be individual predictors of later anxiety symptoms. The significant differences between the various dimensions of alexithymia should be considered in future studies.     

Characterization of alexithymia in clinically isolated syndrome

BackgroundIn multiple sclerosis (MS), the prevalence of alexithymia, defined as an inability to identify and describe emotions, is close to 50% but the prevalence of this symptom in clinically isolated syndrome (CIS) is unknown. Characterizing alexithymia at an early stage of the disease can help to clarify psychobehavioural disturbances in CIS patients.MethodsForty CIS patients, who fulfilled the MRI criteria for dissemination in space, were matched with 40 healthy subjects. They completed self-assessment scales for alexithymia, depression, anxiety, apathy and empathy. Cognitive functions were assessed using a battery of neuropsychological tests.ResultsThe mean delay (± standard deviation) between the occurrence of CIS and inclusion in the study was 3.9 (2.8) months. The frequency of alexithymia was higher in CIS patients than in controls, with a prevalence of 42% (P < 0.0001). Alexithymia correlated with anxiety and depression but not with cognition. Alexithymia was dependent only on depression (P = 0.003).ConclusionAlexithymia, characterized by difficulty identifying feelings, is present in patients in the early stage of MS, and seems to be strongly associated with depression. Difficulty in social interaction could be a risk of future affective disorders.     

The role of alexithymia and gastrointestinal-specific anxiety as predictors of treatment outcome in irritable bowel syndrome

In a previous investigation irritable bowel syndrome (IBS) was associated more to alexithymia than gastrointestinal-specific anxiety (GSA). In this study their independent contribution in predicting treatment outcome was longitudinally investigated. Consecutive 150 IBS patients were evaluated for IBS symptoms, alexithymia, GSA, and psychological distress with validated scales after as-usual treatment for 6–12 months. The primary treatment outcome was improvement measured with the IBS-Severity Scoring System that showed 111 patients who improved and 39 who did not improve. Improvement was associated to both alexithymia (d = 1.27) and GSA (d = 4.63) but only alexithymia showed overtime stability by hierarchical regression, controlled for co-variables. A series of logistic and linear regressions showed that baseline alexithymia, but not GSA, independently predicted both post-treatment improvement status (Cox & Snell R² = 0.15; overall classification rate = 74%) and symptom change (23% of explained variance). Although alexithymia and GSA were closely related IBS symptoms, only alexithymia was found to be a stable trait and a stronger predictor of treatment outcome than GSA. Since no treatment was established to be definitely effective for IBS, clinicians might improve treatment outcome by identifying patients with high alexithymia, attempting to improve their coping skills, emotional regulation, and affective awareness.     

Medically unexplained symptoms in patients with PNES: Do they explain poor employment outcome in patients with good seizure outcomes?

BackgroundMany patients with psychogenic nonepileptic seizures (PNES) have other medically unexplained symptoms (MUS). In order to assess their long-term contribution to ill-health and unemployment, we recorded MUS, employment, healthcare utilization, and seizure outcomes in a cohort of patients with PNES.MethodsWe had complete computerized healthcare records and employment information in 120 patients with PNES, 5–10 years postdiagnosis. We analyzed these data to assess the contribution of MUS to ill-health and to determine whether MUS could explain differences among seizure, employment, and healthcare utilization outcomes in PNES.ResultsAt 5–10 years, 41/120 patients (34.2%) were attending primary or secondary care for seizures, 42/120 patients (35.0%) had MUS other than PNES, and 36/120 patients (30.0%) were employed. Unemployment was predicted by age at presentation (OR: 0.90 (0.86–0.94), p < 0.001), presenting to primary or secondary care with seizures (OR: 0.16 (0.05–0.52), p = 0.003), and contact with psychiatric services at 5–10 years (OR: 0.16 (0.05–0.58), p = 0.005). No outcome measures were predicted by additional MUS, though MUS themselves were predicted by psychiatric contact (OR: 2.27 (1.01–5.01), p = 0.048).ConclusionsOur data suggest that MUS do not contribute independently to unemployment in the population with PNES, whereas psychiatric morbidity appears to do so. Nonetheless, MUS and psychiatric morbidity persist in the long term in a substantial minority of patients with PNES. We found no evidence that seizures in patients whose PNES have resolved are replaced with other MUS.     

Theory of mind abilities in patients with psychogenic nonepileptic seizures

BackgroundPsychogenic nonepileptic seizures (PNES) have been frequently linked to deficits in affect regulation and altered processing of emotionally salient information. However, less is known about how patients suffering from PNES actually process and interpret affective social stimuli. Thus, the present study aimed to investigate basal facial affect recognition as well as mind-reading skills in a sample of patients with PNES and matched control subjects.MethodsPatients with PNES (N = 15) and healthy controls (N = 15) completed self-report questionnaires that measured alexithymia and perceived stress vulnerability. Affect perception was tested using a series of computerized movies of models whose facial expressions slowly change from neutral to full-blown emotions (anger, fear, sadness, happiness, disgust, and surprise), allowing for a fine-grained assessment of facial emotion recognition impairments. Further, all participants were presented with the Movie for the Assessment of Social Cognition, a well-validated video-based test for the evaluation of subtle mind-reading deficits.ResultsData analyses revealed increased alexithymic traits and, impaired mentalizing skills in individuals with PNES, while basal facial expression recognition was not compromised.DiscussionThe present findings are the first to demonstrate that patients with PNES exhibit several deficits in reasoning about their own and other people's mental states. Patients with PNES may benefit from psychotherapeutic interventions that focus on disturbed affect regulation and aim to enhance emotional awareness.     

Self-referral to group cognitive behavioural therapy: Is it effective for treating chronic insomnia?

ObjectivesTo evaluate the effectiveness of a short (3 session) programme of group cognitive behavioural therapy (CBT) on insomnia, sleepiness and symptoms of anxiety and depression.MethodsProspective observational study of group CBT with follow-up at 3 months. Participants were self-referred patients with chronic insomnia. Outcome measures were the insomnia severity scale (ISI), the Epworth sleepiness scale (ESS), depression (Pichot scale), and the number of anxiety symptoms.ResultsParticipation in CBT was offered to 489 patients of whom 474 completed the programme and 154 were followed up at 3 months. Significant improvements in insomnia were seen: ISI score (17.74–14.27, P < 0.0001) after CBT and at follow-up (13.78, P < 0.0001). At the end of CBT, 76% (59/78) with initial severe insomnia and 52% (132/255) with moderate insomnia were improved, maintained at 3 months in 71% (15/21) with severe insomnia and 56% (50/90) with moderate insomnia. Depression and anxiety symptoms were significantly improved: mean depression symptoms (4.15–3.35, P < 0.0001) and anxiety symptoms (4.52–3.95, P < 0.0001), maintained at 3 months with mean depression symptoms (3.17, P < 0.0001) and mean anxiety symptoms (3.62, P < 0.0001). Sleepiness increased between baseline and the end of the group (6.67–7.24, P = 0.015) followed by a reduction at 3 months (7.19–6.34 at 3 months, P = 0.001). Initial ISI score but neither sex nor age were predictive of outcome.ConclusionsA short programme of CBT can improve sleep, depression and anxiety symptoms in self-referred patients suffering from chronic insomnia with good adherence and maximum benefit in patients with severe insomnia.
