Prospective evaluation of psychological distress and psychiatric morbidity in recurrent vasovagal and unexplained syncope

Neuropsychological morbidity in the First Seizure Clinic: Prominent mood symptoms and memory issues in epilepsy

OBJECTIVE

To examine the neuropsychological morbidity across the spectrum of patients presenting to a First Seizure Clinic, and test the hypothesis that cognitive and psychological compromise is especially prominent in those diagnosed with epilepsy.

METHODS

A sample of 201 patients referred to the Austin Hospital First Seizure Clinic (FSC) underwent cognitive screening via telephone and psychological screening via online questionnaire, all prior to their diagnostic evaluation (and any attendant treatment recommendation) at the FSC. Rates of cognitive (i.e., scores <10th percentile) and psychological impairment (using established clinical cut scores) were compared against 35 demographically matched controls. Cognitive differences were explored between the most frequently encountered patient subgroups (epilepsy, n = 48; first unprovoked seizure, n = 24; acute symptomatic seizure, n = 24; syncope, n = 35) via a multivariate analysis of variance, with diagnostic labels applied retrospectively after a period of follow-up.

RESULTS

People with epilepsy were most likely to show cognitive impairments, particularly in learning and memory, with performances worse than all other FSC groups (F [3127] = 2.44, p = 0.03). Clinically significant depressive symptoms were similarly prevalent in all patient groups, with one in three at risk for Major Depressive Disorder. Elevated anxiety symptoms were common across patient groups; however, not significantly different to controls.

SIGNIFICANCE

Cognitive impairment in epilepsy and mood problems in all FSC groups are detectable via remote screening as early as the first seizure. Learning and memory difficulties are particularly prevalent in new-onset epilepsy and may lend diagnostic information when paired with clinical factors.

PLAIN LANGUAGE SUMMARY

This study explored cognitive and psychological differences between various patient groups attending an Australian First Seizure Clinic. We found that learning and memory abilities were poorer in people with epilepsy than other patient groups including those with non-epileptic seizures, and seizure-mimics (fainting episodes). Therefore, along with standard epilepsy investigations, memory performances could help to predict which patients have epilepsy versus a non-epileptic condition after a first suspected seizure. Further, approximately one in three from each patient group showed high symptoms of depression and anxiety. The findings highlight the importance of evaluating cognition and mood in people with first seizures.

Anxiety, depressive, and somatoform disorders in children and adolescents referred to paediatric cardiology with somatic symptoms

INTRODUCTION

Chest pain, palpitations, and syncope are among the most common referrals to paediatric cardiology. These symptoms generally have a non-cardiac aetiology in children and adolescents. The aim of this study was to investigate the rate of common psychiatric disorders in children and adolescents referred to the paediatric cardiology clinic with chest pain, palpitations, and syncope and the relationship between cardiological symptoms and psychiatric disorders.

METHODS

Children and adolescents aged 8-16 years who presented at the paediatric cardiology clinic with primary complaints of chest pain, palpitation, or syncope were included in the study. After a detailed cardiology examination, psychiatric disorders were assessed using the DSM IV-TR diagnostic criteria and a semi-structured interview scale (KSADS-PL). The Child Depression Inventory and Spielberger's State-Trait Anxiety Inventory for Children were also applied to assess the severity of anxiety and depression.

RESULTS

The study participants comprised 73 (68.90%) girls and 33 (31.10%) boys with a mean age of 12.5 ± 2.4 years. Psychiatric disorders were determined in a total of 48 (45.3%) participants; 24 (38.7%) in the chest pain group, 12 (48.0%) in the palpitation group, and 12 (63.2%) in the syncope group. Cardiological disease was detected in 17% of the cases, and the total frequencies of psychiatric disorders (p = 0.045) were higher in patients with cardiological disease.

CONCLUSION

It is clinically important to know that the frequency of psychiatric disorders is high in patients presenting at paediatric cardiology with chest pain, palpitations, and syncope. Physicians should be aware of patients' psychiatric problems and take a biopsychosocial approach in the evaluation of somatic symptoms.

Association of Occupational Distress and Low Sleep Quality with Syncope, Presyncope, and Falls in Workers

Syncope and presyncope episodes that occur during work could affect one's safety and impair occupational performance. Few data are available regarding the prevalence of these events among workers. The possible role of sleep quality, mental stress, and metabolic disorders in promoting syncope, presyncope, and falls in workers is unknown. In the present study, 741 workers (male 35.4%; mean age 47 ± 11 years), employed at different companies, underwent clinical evaluation and blood tests, and completed questionnaires to assess sleep quality, occupational distress, and mental disorders. The occurrence of syncope, presyncope, and unexplained falls during working life was assessed via an ad hoc interview. The prevalence of syncope, presyncope, and falls of unknown origin was 13.9%, 27.0%, and 10.3%, respectively. The occurrence of syncope was associated with an increased risk of occupational distress (adjusted odds ratio aOR: 1.62, confidence intervals at 95%: 1.05-2.52), low sleep quality (aOR: 1.79 CI 95%: 1.16-2.77), and poor mental health (aOR: 2.43 CI 95%: 1.52-3.87). Presyncope was strongly associated with occupational distress (aOR: 1.77 CI 95%: 1.25-2.49), low sleep quality (aOR: 2.95 CI 95%: 2.08-4.18), and poor mental health (aOR: 2.61 CI 95%: 1.78-3.84), while no significant relationship was found between syncope or presyncope and metabolic syndrome. These results suggest that occupational health promotion interventions aimed at improving sleep quality, reducing stressors, and increasing worker resilience might reduce syncope and presyncope events in the working population.

The Psychopathology, Depression, and Anxiety Levels of Children and Adolescents With Vasovagal Syncope: A Case-Control Study

ABSTRACT

Vasovagal syncope constitutes 61% to 80% of syncope cases in the pediatric age group. Syncope is frequently associated with psychopathologies such as depressive disorders, anxiety disorders, somatization disorders, etc. Our study aims to evaluate vasovagal syncope cases in terms of additional psychopathologies, depression, and anxiety levels with a control group. A total of 97 people were included in the study (47 cases and 50 controls). After conducting a cardiological examination, the participants were evaluated for psychopathologies using Kiddie-Sads-Present and Lifetime Version, Child Depression Inventory, and Screen for Child Anxiety Related Emotional Disorders. The case group had a higher rate of psychopathology compared with the control group. Depression, social anxiety disorder, generalized anxiety disorder, separation anxiety, and conversion disorder were significantly higher in the case group than in the control group. Syncope in children can be an underlying psychopathology or the clinical manifestation of a psychosomatic condition. Psychological assessment, which could offer beneficial contributions to the diagnosis and treatment of syncope, was considered necessary for a holistic evaluation of patients.

Are women really more affected by vasovagal syncope than men?

It is commonly reported that vasovagal syncope (VVS) is more frequent in women. Presently, this issue has never been investigated. The purpose of this review was to evaluate, through an extensive review of the literature, whether women are really more affected by VVS than men. The gender distribution was investigated in individuals with classical and nonclassical VVS. The database PubMed was searched using the terms 'syncope', 'vasovagal syncope', 'neurally mediated syncope' and 'tilt testing'. Twelve studies dealing with classical and 75 with nonclassical VVS were eligible. In the individuals with classical (N = 1861) and nonclassical VVS (N = 9696), a trend towards a greater percentage of women emerged (P = 0.14 and 0.07, respectively). In the total population with VVS (N = 11 557), the percentage of women was significantly higher than that of men (58 versus 42%, P = 0.03). Most of the individuals were young or middle-aged. In 84% of the studies, the percentage of women was greater than that of men. A separate analysis was carried out in older VVS patients (≥60 years) and only two studies were eligible to be evaluated. Considering that almost all the studies were carried out in the western nations, where the number of men and women is almost superimposable until the age of 65 years and a bias by gender has never been reported in the management of VVS, these data strongly suggest that young and middle-aged women are more affected by VVS than their male counterparts. At present, data are too scant to draw a definitive conclusion in older VVS patients.

Psychogenic Pseudosyncope: Clinical Features, Diagnosis and Management

Psychogenic Pseudosyncope (PPS) is the appearance of Transient Loss of Consciousness (TLOC) in which movements are absent, but there are no hemodynamic and electroencephalographic modifications as are induced by gravitational challenges which characterize syncope and true loss of consciousness. For younger and adult populations, a detailed history is crucial for the diagnosis. Clinical clues that should raise the suspicion for PPS include prolonged duration of the LOC, eye closure during the episode, unusual triggers, no recognizable prodromes and the high frequency of attacks. The presence of an established diagnosis of syncope should not deter from the concomitant diagnosis of PPS. The gold standard for a proper diagnosis of PPS is the documentation by a tilt test of normal hemodynamic and electroencephalographic parameters, when recorded during an attack. Treatment of PPS, based on the clear and empathetic communication of the diagnosis, can lead to an immediate reduction of attack frequency and lower the need to call on emergency services. Pharmacological treatment of associated psychiatric disorders and psychological interventions may be beneficial in patients with PPS. Cognitive-behavioural therapy holds the most reliable evidence of efficacy. In the present review, we aimed to address PPS with historical aspects, main clinical features and diagnostic tests, current diagnostic classification, underlying neurobiological abnormalities, management and therapy.

The relationship between clinical characteristics and psychological status and quality of life in patients with vasovagal syncope

OBJECTIVE:

Syncope is characterized by sudden and short-term loss of postural tone and consciousness. Vasovagal syncope (VVS) episode is usually self-limiting, and it may affect patients’ quality of life. In this study, we aimed to investigate the relationship between quality of life, Beck-depression and Beck-anxiety scales and clinical characteristics of the VVS patients.

METHODS:

The present study included 88 patients with VVS. Tilt table test was performed to all the patients. Patients filled out the Quality of life, Beck-depression, and Beck-anxiety scale forms. Demographics, medical history, echocardiography, blood pressures, electrocardiography and physical examination findings were recorded.

RESULTS:

There was a significant and negative correlation between the total syncope episodes (TSE) and EQ-5D index and EQ-5D-VAS index, respectively (p<0.001, r: -0.649; p<0.001, r: -0.587). TSE was significantly and positively correlated with the Beck-anxiety scale and Beck-depression scale. EQ-5D index, EQ-5D-VAS index, Beck-depression scale, and Beck-anxiety scales were defined as an independent predictor of TSE in VVS patients.

CONCLUSION:

Psychological factors play an essential role in VVS patients. EQ-5D index, EQ-5D-VAS index, Beck-depression, and Beck-anxiety scales were an independent predictor of the TSE in patients with VVS.

Impaired sleep quality is associated with concurrent elevations in inflammatory markers: are post-menopausal women at greater risk?

Abstract

Background

Chronic inflammation and impaired sleep increase the risk for cardiovascular disease. Menopausal women may be particularly at risk as a result of impaired sleep. The objective of the current investigation was to assess the relationship between poor sleep and C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and myeloperoxidase (MPO) in healthy non- and postmenopausal women and men.

Methods

A fasting blood draw was obtained from 122 healthy men and women (31 were postmenopausal). Higher scores on the Pittsburgh Sleep Quality Index (PSQI) were used to define poor sleep. Given the sample size and healthy nature of the sample, hierarchical linear regression analyses were performed on a composite inflammatory score involving CRP, IL-6, and TNF-α. Sex/menopausal group and PSQI were entered as predictors, and the interaction of the group by PSQI was entered stepwise. Analyses on MPO were performed separately.

Results

Sleep quality was associated with higher inflammatory activity (β = 0.272, P = 0.003), which remained significant (P = 0.046) after controlling for age, waist circumference, exercise times per week, and depressive symptoms. While in the same direction, sleep quality was not significantly associated with MPO. Dichotomizing sleep quality led to similar results.

Conclusion

Impaired sleep quality is independently associated with greater inflammation in healthy adult men and women. Despite an overall less favorable metabolic and inflammatory profile in postmenopausal women, impaired sleep did not emerge as differentially related to inflammatory activity in this group.

Reduced quality of life and greater psychological distress in vasovagal syncope patients compared to healthy individuals

BACKGROUND

Vasovagal syncope (VVS) patients have a reduced health-related quality of life (HRQoL). There are limited data comparing HRQoL and psychological profile in VVS patients and healthy individuals. We tested the hypothesis that VVS patients have greater impairment in both HRQoL and psychological profile compared to healthy nonfainting individuals, and that both outcome measures are negatively correlated for VVS patients.

METHODS

The RAND 36-Item Health Survey (RAND36), global health visual analogue scale (VAS), Hospital Anxiety and Depression Scale, Anxiety Sensitivity Index, and Positive and Negative Affect Schedule - Expanded Form were completed by healthy individuals and at baseline by VVS patients enrolled in the Second Prevention of Syncope Trial, a randomized, placebo-controlled trial of fludrocortisone for VVS.

RESULTS

Data were available on 76 VVS patients (34 ± 14 years; 68% F) and 85 healthy participants (35 ± 11 years; 80% F). Compared to healthy participants, VVS patients reported poorer HRQoL on all scales of the RAND36 and the VAS. VVS patients had significantly greater anxiety, depression, and anxiety sensitivity (each P < 0.001). VVS patients had more negative affect (P < 0.001) and less positive affect (P = 0.003) compared to healthy participants. Anxiety, depression, and anxiety sensitivity were negatively correlated with HRQoL for VVS patients, but not for healthy participants.

CONCLUSION

In this first direct comparison, VVS patients have a significantly reduced HRQoL and more anxiety and depression compared to healthy nonfainting individuals. For VVS patients, there is a relationship between psychological distress and HRQoL, suggesting a potential benefit from more comprehensive assessment and treatment.

Psychiatric traits in patients with vasovagal and unexplained syncope

Purpose

Syncope is a common condition affecting almost one-third of the general population. The present study measures the prevalence of psychiatric traits in patients presenting with syncope (unexplained and vasovagal) and whether recurrent attacks have an impact on psychiatric profiles.

Patients and methods

This is a case–control study in a tertiary hospital enrolling all patients aged ≥12 years with single or recurrent syncopal attacks. A self-reporting psychometric questionnaire (The Symptoms Checklist-90-Revised) was used to screen for depression, anxiety, somatization disorder, and phobia. Crude comparisons of average scores were done. Further, multiple logistic regression analyses were carried out to measure the impact of syncope on each psychiatric domain. The control group were matched for age, gender, and chronic illnesses with a ratio of 1:3.

Results

There were 43 cases and 129 control subjects, with predominance of females (67.4%) and an average age of 33.8 years (standard deviation = 16). There were no significant differences in average scores of depression (13 vs 14.53, P = 0.31), anxiety (11.3 vs 10.4, P = 0.51), or phobia (5.4 vs 5.2, P = 0.88). However, the syncope group had a higher average score for somatization disorder (18.53 vs 13.66, P = 0.002). Binary logistic regression model showed that the association between syncope and somatization disorder was independent of competing confounders (odds ratio = 3.75, 95% confidence interval: 1.72, 8.15, P = 0.001). A sub-analysis of the case group showed that patients with multiple syncopal attacks (six or more) had higher average scores of depression, anxiety, phobia, and somatization disorder compared to those who had less than six attacks.

Conclusion

Syncope was independently associated with somatization disorder traits. Further, recurrent syncope resulted in greater deterioration of patients’ psychiatric profiles. Thus, taking into account the psychiatric status in the management of such patients is crucial.

Temperament and character personality dimensions in nitrate-tilt-induced vasovagal syncope patients

OBJECTIVE

Vasovagal syncope (VVS) is a clinical syndrome that is characterized by a transient loss of consciousness and postural tone that are due to a temporary, spontaneously self-terminating global cerebral hypoperfusion. It is known that personality modulates the individual's sensitivity to stressors and that emotional arousal and psychologic uncertainty are conditions that contribute to vasodepressor syncope. Therefore, it is postulated that the personality characteristics of VVS patients could play a role in the pathophysiology of VVS. The aim of our study was to evaluate the temperament and character personality dimensions in patients with VVS as confirmed by nitrate-induced tilt testing.

METHODS

From the 450 consecutive patients referred to our Syncope Unit for transient loss of consciousness, we enrolled 162 patients who had positive results from the head up tilt test for VVS and 162 healthy subjects matched for age and sex. All patients underwent a structured clinical interview with a psychologist to exclude the presence of current psychiatric comorbidities and were asked to complete the Cloninger's Temperament and Character Inventory-Revised (TCI-R) questionnaire for psychological assessment.

RESULTS

Compared to healthy subjects, both male and female patients with VVS were found to have higher scores of the persistence temperament and self-transcendence character traits. Moreover, male VVS patients had lower scores in "novelty seeking", while female VVS patients scored significantly higher in "reward dependence".

CONCLUSION

Our data show that VVS patients significantly differ from matched healthy controls in some temperament and character personality dimensions. Cardiologists should consider referral for psychological assessment when treating patients with refractory VVS.

Use of the Psychosocial Index: A Sensitive Tool in Research and Practice

BACKGROUND

The Psychosocial Index (PSI) is a self-rating scale based on clinimetric principles that is simple to use in a busy clinical setting. It can be integrated by observer-rated clinical judgment, providing a first-line, comprehensive assessment of stress, well-being, distress, illness behavior, and quality of life. By calculation of scores, it can be used for conventional psychological measurements. Its clinical applications and clinimetric properties are reviewed. The present version of the PSI has been slightly revised. In addition, a modified version for use in adolescents and young adults (PSI-Young; PSI-Y) is also included.

METHODS

Articles that involved the use of the PSI were identified by searching the Web of Science database from 1998 to February 2016 and by a manual search of the literature.

RESULTS

A total of 20 studies reporting results from the use of PSI were included. The PSI has been employed in various clinical populations in different countries and showed high sensitivity. It significantly discriminated varying degrees of psychosocial impairment in different populations. When subjects were identified by categorical criteria (presence of allostatic overload, psychosomatic syndromes, psychiatric disorders), the PSI scores were significantly different across subgroups.

CONCLUSIONS

In clinical practice, scanning the list of symptoms allows clinicians to assess rapidly which symptoms and problems are perceived as most troublesome. In research settings, the use of scores makes the PSI a valid and sensitive tool in differentiating levels of psychosocial variables among groups.

Fluoxetine vs. placebo for the treatment of recurrent vasovagal syncope with anxiety sensitivity

AIMS

The optimal medical therapy of patients with vasovagal syncope (VVS) remains controversial. Fluoxetine is effective against anxiety and panic disorders, while its use has shown promising results for VVS. Anxiety sensitivity is a personality trait observed in a considerable proportion of patients with VVS, associated with predisposition to anxiety and panic disorders. Our aim was to examine whether fluoxetine exerts beneficial effects regarding VVS prevention in the subset of patients with anxiety sensitivity.

METHODS AND RESULTS

We assessed 106 patients with typical history of recurrent VVS, without other comorbidities, and a diagnostic, positive head-up tilt test. A psychiatric examination ruled out clinical psychiatric disease. Their psychological, stress-related profile was assessed by the Anxiety Sensitivity Index (ASI) questionnaire, a 16-item questionnaire, assessing fear of anxiety-related sensations, previously studied in VVS. Patients scoring positive for ASI (n = 60, 57% of the population) were randomized in a 2:1 fashion to receive either 10-40 mg fluoxetine daily (n = 40) or placebo (n = 20), and were followed-up for 1 year. A significant difference was observed between patients receiving fluoxetine and those with placebo, regarding the distribution of syncope-free time during the study (P < 0.05). A significant difference was also observed between the two groups regarding presyncopal events and the total number of patients who experienced syncope or presyncope during follow-up.

CONCLUSION

Sensitivity to anxiety is a common personality trait in recurrent VVS. Fluoxetine is superior to placebo against syncope in these patients. This drug may be a first-line pharmacological treatment for this difficult-to-treat group.

The relationship between syncope, depression and anti-depressant use in older adults

BACKGROUND

syncope is a common problem which increases in older age groups. In syncope clinics, patients who are depressed have higher rates of unexplained syncope and higher rates of recurrent syncope.

OBJECTIVES

: we aim to examine the rates of depression in older patients reporting syncope and the effect of anti-depressants (ADs) on the rates of syncope.

DESIGN

: epidemiological, point-prevalence study.

SETTING AND PARTICIPANTS

: data came from the Irish Longitudinal Study on Ageing, which includes 8,175 adults aged 50 and older, living in the community in Ireland.

MEASUREMENTS

: the Centre for Epidemiological Studies Depression scale was used to assess levels of depression. Multinomial regression was used to analyse the data with a P-value of <0.05 determining significance.

RESULTS

: 7,993 participants aged 50 and older were included, and of these 349 reported at least one syncopal episode in the last year. Prevalence of syncope was 4.4%. After controlling for participant characteristics and general health, those with severe depression had a greater risk of single and multiple syncopal events (relative risk ratios [RRR]: 2.78 and 2.84, respectively, P < 0.050) and participants treated with tricyclic anti-depressants (TCAs) were also at greater risk for single and multiple syncopal episode in the last year (RRR: 2.31, P = 0.062; RRR: 2.95, P < 0.05).

CONCLUSIONS

: this study demonstrates an increased risk of syncope in patients with depression, with higher rates of syncope reported with increasing severity of depression. Treatment with TCAs increases both the risk and frequency of syncope in the community. Depression is a potentially modifiable risk factor for syncope but treatment options need to be tailored in the older patient population.

Prevalence and clinical factors of anxiety and depression in neurally mediated and unexplained syncope

PURPOSE

Several studies have demonstrated that psychiatric disorders such as anxiety, depression and panic attack are associated with syncope, especially vasovagal and unexplained syncope (US). The aim of this study was to compare the prevalence of anxiety and depression between patients with neurally mediated syncope (NMS) and US and to investigate the clinical factors associated with anxiety and depression.

MATERIALS AND METHODS

Between January 2009 and March 2010, 383 patients with syncopal episodes completed a Hospital Anxiety and Depression Scale questionnaire to assess symptoms of anxiety and depression. Inclusion criteria were NMS and US. Exclusion criteria were cardiac syncope, orthostatic hypotension and other disorders mimicking syncope. After exclusion, 199 patients were included.

RESULTS

There were 176 (88.4%) NMS patients and 23 (11.6%) US patients. The prevalence of abnormal anxiety and depression were not significantly different between the NMS and US groups (10.2% vs. 8.7%, p=0.99; 8.5% vs. 17.4%, p=0.24). Clinical factors associated with anxiety were female gender (p=0.01) and six or more recurrent syncopal episodes (p=0.01) by univariate analysis. The only factor associated with abnormal anxiety score (OR=20.26, 95% CI: 1.4-291.6, p=0.01) was more than six recurrent syncopal episodes, while a positive head-up tilt table testing response was inversely associated with abnormal depression score (OR=0.28, CI: 0.08-0.97, p=0.04) in the multiple logistic regression analysis.

CONCLUSION

Anxiety was associated with frequent syncopal episodes. Thus, anxiety might be considered in the management of syncope patients.

Psychological correlates of vasovagal versus medically unexplained syncope

OBJECTIVE

Psychiatric morbidity is quite common in vasovagal syncope (VVS), but findings are sometimes contradictory. Among patients with suspected VVS, up to 40% has a negative response to Head-Up Tilt test (HUT), the cause of syncope remaining unexplained (US). The authors evaluated and compared the psychological and psychosomatic profile in patients with positive (VVS) and negative HUT (US).

METHOD

A consecutive series of 67 patients with suspected VVS underwent HUT: 45 patients had a positive HUT, 22 negative. They were evaluated by means of observer- and self-rated measures.

RESULTS

Of the total sample, 95.5% had at least one Diagnostic and Statistical Manual of Mental Disorders diagnosis or one psychosomatic syndrome, such as specific and social phobias, illness denial and demoralization. Comparing VVS and US patients, no statistical differences on diagnoses' frequencies were found. However, the US group had significantly poorer health habits, lower levels of well-being and higher psychological distress. They also reported to be more anxious, depressed and hostile. VVS patients were significantly more blood and social phobic than US patients.

CONCLUSION

Despite similar and remarkable observer-rated psychopathology, US patients reported higher self-perceived psychological distress than VVS patients. Psychological evaluation of patients undergoing HUT should incorporate both clinical and subclinical methods to better address syncope management.

Depressive symptoms and neurocardiogenic syncope in children: a 2-year prospective study

OBJECTIVE

To evaluate prospectively the relationship between neurocardiogenic syncope (NCS) and depressive symptoms in pediatric patients.

METHODS

Forty-five patients (aged 12.3 ± 2.9 years) with NCS (diagnosed as ≥ 1 syncopal episodes with typical symptoms, reproduced by tilt-table testing, in the absence of structural or primary electrical heart disease) were compared with 45 age- and gender-matched control subjects. Assessment was performed at baseline and 2 years thereafter. Depressive symptoms and self-perception profile of participants were evaluated, along with their parents' psychological distress, defensive profile and hostility. Family cohesion and adaptability, as well as the opinion of parents and teachers on children's strengths and difficulties, were also examined.

RESULTS

At baseline, patients showed more (P = .008) depressive symptoms than controls, correlating with the number of syncopal episodes, impaired relationship with parents and poor family cohesion. A conservative management strategy of NCS was adopted and psychological counseling was offered, focusing on patients with clinically significant depressive symptoms and their families. During follow-up, depressive symptoms decreased in patients (P < .001), but remained stable in controls. Child-parent relationship, family cohesion and family adaptability improved at follow-up in patients. No recurrent syncope was noted during follow-up and this along with improvement in child-parent relationship were associated with depressive symptoms improvement.

CONCLUSIONS

Depressive symptomatology is common in pediatric patients with NCS. Our findings call for additional investigation in larger controlled clinical interventional studies that will enhance understanding of the possible pathophysiological association between depressive symptomatology and NCS in pediatric populations.

Association between psychological complaints and recurrence of vasovagal syncope

PURPOSE

Vasovagal syncope (VVS), the most common cause of transient loss of consciousness (T-LOC), is often accompanied by higher levels of psychological distress. We investigated to what extent psychological complaints interact with the effects of non-pharmacological treatment in patients with frequently recurring VVS.

METHODS

Patients with ≥3 episodes of VVS in the 2 years prior to the start of the study openly received non-pharmacological treatment. Before treatment initiation, we determined the level of general psychological complaints by the Symptom Checklist 90-R (SCL-90-R) questionnaire. We regularly evaluated syncopal recurrence during follow-up. We compared the SCL-90-R scores of VVS patients in our study with the corresponding scores of healthy Dutch subjects (reference population). We examined whether patients with more recurrences during follow-up had higher SCL-90-R scores at baseline and whether this association changed when adjusting for other factors associated with recurrence using logistic regression.

RESULTS

Total SCL-90-R scores were higher in our cohort of patients with frequent episodes of VVS than in the reference population (142 vs. 118; p < 0.001). During the first 6 months of treatment, 42% of patients experienced syncopal recurrence(s). The SCL-90-R scores of these patients were significantly higher compared with patients without syncopal recurrence in this period (160 vs. 130; p = 0.01). After adjusting for other predictors of recurrence, especially the number of episodes before inclusion, the association between SCL-90-R scores and recurrence remained intact.

CONCLUSIONS

Levels of general psychological complaints are higher in patients with syncopal recurrence during non-pharmacological treatment of VVS, even after adjusting for previous syncopal episodes.

Outcome and consequences according to the type of transient loss of consciousness: 1-year follow-up study among primary health care patients

The prognosis of transient loss of consciousness (LOC) was studied in a one-year follow-up survey. Included were adult patients referred by primary health care physicians for a non-acute specialist consultation during the 2-year period from 01.10.1999 to 30.9.2001. The main outcome measures were recurrence of LOCs during the follow-up, fear of recurrence, injuries, and employment. Altogether, 109 consecutive patients were followed and 39 (36%) suffered a recurrence during the one-year follow-up: 17 (30%) with syncope, 16 (43%) with seizure and six (38%) with uncertain type of LOC. The first ever seizure recurred in 5/9 (56%) during the first year, but only 1 of 17 (6%) first syncope attacks. There was no difference in the recurrence rate if the patient had had previous attacks prior to the index LOC. Injuries, mainly minor, were associated with LOCs in 56% of patients. The risk of injury was highest (83%) with alcohol-related seizures. The unemployment rate was especially high in the seizure group. Fear of recurrence was more common at the beginning than at the end of the follow-up.

CONCLUSIONS

Seizures recur relatively often, but also recurrent syncope needs more attention--both may cause fear and lead to injuries.
