Insomnia moderates the association between recurrent seizures and emotional instability in persons with epilepsy

Sleep disturbances in Norwegian children with fetal alcohol spectrum disorders (FASD) with and without a diagnosis of attention-deficit hyperactivity disorder or epilepsy

BACKGROUND

Fetal alcohol spectrum disorder (FASD) describes a combination of developmental, cognitive, and behavioral disabilities in children with prenatal exposure to alcohol. The literature suggests that there are higher rates of sleep disturbances in these children. Few studies have investigated sleep disturbances in relation to common comorbidities of FASD. We examined the prevalence of disturbed sleep and the relationship between parent-reported sleep problems in different FASD subgroups and comorbidities like epilepsy or attention-deficit hyperactivity disorder (ADHD) and impact on clinical functioning.

METHODS

In this prospective cross-sectional survey, caregivers of 53 children with FASD completed the Sleep Disturbance Scale for Children (SDSC). Information about comorbidities was collected, and EEG and assessment of IQ, daily-life executive and adaptive functioning were performed. Group comparisons and ANCOVA interaction models were used to test the associations between different sleep disturbances and clinical factors that could interfere with sleep.

RESULTS

An abnormal sleep score on the SDSC was very common, affecting 79% of children (n = 42) with equal prevalence in all FASD subgroups. Difficulty falling asleep was the most common sleep problem, followed by difficulty staying asleep and waking early. The incidence of epilepsy was 9.4%, with an abnormal EEG seen in 24.5%, and a diagnosis of ADHD in 47.2% of children. The distribution of these conditions was equal in all FASD subgroups. Children with signs of sleep disturbance had poorer working memory, executive function, and adaptive functioning. Children with ADHD had a greater prevalence of sleep disturbance than those without ADHD (OR 1.36; 95% CI 1.03 to 1.79).

CONCLUSION

Problems with sleep are very common in FASD children and seem independent of FASD subgroup and the presence of epilepsy or a pathological EEG finding, while those with ADHD had more sleep problems. The study underscores the importance of screening for sleep disturbances in all children with FASD as these problems may be treatable.

Effects of progressive muscle relaxation exercises on patients with epilepsy on level of depression, quality of sleep, and quality of life: A randomized controlled trial

OBJECTIVE

This study aims to evaluate the effects of progressive relaxation exercises applied to patients with epilepsy on patients' depressive symptom severity, quality of sleep, and quality of life.

METHODS

The study was designed as a randomized controlled interventional study with a control group and pre-and post-test intervention. It was conducted with 70 patients with epilepsy, 35 in the intervention group and 35 in the control group, between November 1, 2021, and April 15, 2022. The patients in the intervention group were required to perform 12 progressive muscle relaxation exercise sessions 3 days a week for a total of 4 weeks. No interventions were made in the control group during the study. The data were collected with a "Personal Information Form," "Pittsburgh Sleep Quality Index (PSQI)," "Beck Depression Inventory (BDI)," and "Quality of Life in Epilepsy Inventory (QUOLIE -31)."

RESULTS

The mean PSQI total score, subscale scores, and mean BDI total scores of the patients in the intervention group decreased significantly compared to those in the control group after the intervention (p<0.05). Additionally, a significant difference was found between the mean QUOLIE-31 total scores and subscale scores of the patients in the intervention and control group after the intervention (p<0.05), the mean scores of the intervention group were significantly higher than those of the control group (p<0.05).

CONCLUSION

Progressive muscle relaxation exercises decreased depressive symptoms severity and improved sleep and life quality in patients with epilepsy. Progressive relaxation exercises may be recommended as a complementary nursing intervention in treating epilepsy.

Risk Prediction Models for Early ICU Admission in Patients With Autoimmune Encephalitis: Integrating Scale-Based Assessments of the Disease Severity

Background

In patients with autoimmune encephalitis (AE), the prediction of progression to a critically ill status is challenging but essential. However, there is currently no standard prediction model that comprehensively integrates the disease severity and other clinical features. The clinical assessment scale in autoimmune encephalitis (CASE) and the modified Rankin Scale (mRS) have both been applied for evaluating the severity of AE. Here, by combining the two scales and other clinical characteristics, we aimed to investigate risk factors and construct prediction models for early critical care needs of AE patients.

Methods

Definite and probable AE patients who were admitted to the neurology department of Tongji Hospital between 2013 and 2021 were consecutively enrolled. The CASE and mRS scores were used to evaluate the overall symptom severity at the time of hospital admission. Using logistic regression analysis, we analyzed the association between the total scores of the two scales and critical illness individually and then we evaluated this association in combination with other clinical features to predict early intensive care unit (ICU) admission. Finally, we constructed four prediction models and compared their performances.

Results

Of 234 patients enrolled, forty developed critical illness and were early admitted to the ICU (within 14 days of hospitalization). Four prediction models were generated; the models were named CASE, CASE-plus (CASE + prodromal symptoms + elevated fasting blood glucose + elevated cerebrospinal fluid (CSF) white blood cell (WBC) count), mRS and mRS-plus (mRS + prodromal symptoms + abnormal EEG results + elevated fasting blood glucose + elevated CSF WBC count) and had areas under the ROC curve of 0.850, 0.897, 0.695 and 0.833, respectively. All four models had good calibrations. In general, the models containing “CASE” performed better than those including “mRS”, and the CASE-plus model demonstrated the best performance.

Conclusion

Overall, the symptom severity at hospital admission, as defined by CASE or mRS, could predict early ICU admission, especially when assessed by CASE. Adding other clinical findings, such as prodromal symptoms, an increased fasting blood glucose level and an increased CSF WBC count, could improve the predictive efficacy.

Aggression is more strongly associated with suicidality, independent of depression, than emotional instability and impulsivity in people with epilepsy

PURPOSE

We evaluated the relative contributions of emotional instability, impulsivity, and aggression to the presence of suicide risk in people with epilepsy after adjusting for depressive symptoms.

METHODS

This was a cross-sectional study that used the short form of the Affective Lability Scale (ALS-18), the Barratt Impulsiveness Scale Version 11 (BIS-11), the Brief Aggression Questionnaire (BAQ), and the Patient Health Questionnaire-9 (PHQ-9). Suicidality was assessed using the Mini International Neuropsychiatric Interview (MINI), and the presence of suicide risk was defined as a MINI suicidality score ≥1. Stepwise logistic regression and mediation analyses using a two-stage regression method were performed.

RESULTS

Of the 171 subjects (63.2% men) included, suicide risk was present in 38 subjects (22.2%). The stepwise logistic regression analysis identified four variables that were independently associated with suicide risk: higher PHQ-9 score, higher BAQ score, longer duration of epilepsy, and unemployment. The univariate analysis showed that ALS-18 and BIS-11 scores were significantly associated with suicide risk; however, they were backward eliminated from the logistic model according to the criterion of p > 0.1. The mediating effects of ALS-18 and BIS-11 scores on suicide risk via PHQ-9 scores (but not BAQ scores) were significant, with the proportion mediated 61.5% and 54.0% of the total effect, respectively.

CONCLUSIONS

Alongside depressive symptoms, aggression may be a more useful concept than emotional instability and impulsivity for identifying suicidal risk in people with epilepsy.
