Positive psychological interventions for people with epilepsy: An assessment on factors related to intervention participation

Factors associated with illness representations in adults with epileptic and functional seizures: A systematic review

Illness representations refer to a person's beliefs about their health condition and are thought to influence clinical outcomes. By understanding factors related to illness representations, potentially modifiable targets for psychological intervention can be identified. The aim of this systematic review was to synthesise the literature on factors associated with illness representations in people with epilepsy and functional seizures. Three electronic databases (Psychinfo, EMBASE, and Proquest (Theses and dissertations)) were searched for studies that reported on associations between Illness Perception Questionnaire scores (or variations thereof) and biopsychosocial factors in people with epilepsy or people with functional seizures. Seventeen studies met inclusion criteria and were assessed with a bespoke quality appraisal tool. Overall, there was moderately strong evidence for an association between more threatening illness representations and poorer clinical outcomes relating to seizure characteristics, distress, coping, and quality of life; the evidence for these relationships was stronger for people with epilepsy than functional seizures. There was no clear difference between the illness representations of the two groups. The results of this review highlight the clinical importance of illness representations in people with seizure disorders, as well as opportunities for further research.

Mindfulness-based intervention to promote psychological wellbeing in people with epilepsy: A randomized controlled trial

BACKGROUND

We investigated the efficacy of mindfulness-based intervention (MBI) in promoting psychological wellbeing in people with epilepsy (PWE) using an assessor-blinded randomized controlled design.

METHODS

A total of 28 PWE were randomly assigned to either intervention (n = 14 cases) or control group (n = 14 controls). The intervention group received a six 2.5-hour weekly MBI, while the control group did not receive any intervention. They were assessed at three timepoints (T0: before intervention, T1: immediately after intervention, and T2: 6 weeks after intervention). Repeated measures of analyses of variance (RM-ANOVAs) were used for inter-group comparisons to determine intervention effect from baseline -to T1 and -to T2 for all outcome measures. The individual changes were calculated using the reliable change index (RCI). Key outcomes included depression (BDI-II), anxiety (BAI), epilepsy-related quality of life (QOLIE-31), satisfaction with life (SWLS), and level of mindfulness (MAAS).

RESULTS

Participants who participated in the MBI showed significant reduction in BDI-II (p = 0.001), significant increases in MAAS (p = 0.027) and QOLIE-31 (p = 0.001) at T1 when compared with the control group. However, BAI and SWLS were not significant. The trend was similar at 6-week follow-up, all outcome measures of MBI remained significant (p < 0.05) except for BAI and SWLS. Beyond the 6-week intervention, RCI analysis showed a significant improvement in levels of mindfulness (45.45% vs. 21.43%, p = 0.009), depression (45.45% vs. 0.00%, p = 0.016), quality of life (45.45% vs. 14.29%, p = 0.017) with MBI, as compared to the no-intervention phase.

CONCLUSION

Mindfulness-based intervention is effective in reducing psychological distress and improving the quality of life in PWE.

Neurologist prescribing versus psychiatry referral: Examining patient preferences for anxiety and depression management in a symptomatic epilepsy clinic sample

OBJECTIVE

Anxiety and depression symptoms in epilepsy are common, impactful and under-recognized and undertreated. While prior survey data suggests equipoise among epileptologists for managing anxiety and/or depression via prescribing in the epilepsy clinic versus psychiatry referral, patient preferences are unknown and should potentially influence practice habits among epileptologists. Thus, the primary objective of this study was to determine patient preference for anxiety and/or depression prescribing by neurologists versus psychiatry referral among an adult epilepsy clinic sample of symptomatic patients.

METHODS

Management preferences for anxiety and/or depression were surveyed in an adult tertiary care epilepsy clinic. Individuals who screened positive for anxiety and/or depression symptoms on validated instruments during a routine care-embedded learning health system study were recruited. Demographics, social variables, psychiatric treatment history, and treatment priorities and preferences were surveyed. Preference was defined as a slightly greater than 2:1 ratio in favor neurology prescribing or psychiatry referral. The study was powered to assess this primary objective using a two-sample binomial test. Multinomial logistic regression examined an a priori multivariable model of treatment preference (secondary objective).

RESULTS

The study sample included N = 63 symptomatic adults, with 64% women and mean age 42.2 years. Most reported past or current treatment for anxiety and/or depression, and treatment for these symptoms was a high or moderate priority among 65.1% of the sample. Neurologist prescribing was preferred in 83.0% (nearly 5:1) over psychiatry referral among those who chose neurology or psychiatry (as opposed to neither of the two; p < 0.001, 95% CI 0.702-0.919). Overall, 69.8% of the total study sample preferred neurology prescribing. Multivariable modeling indicated preference for neither management option (compared with neurologist prescribing) was associated with low overall treatment prioritization and having never received neurologist medication management. None of the factors examined in the a priori multivariable model were associated with selecting psychiatry referral (compared to neurologist prescribing).

CONCLUSION

In this sample, most patients indicated a preference for neurologists to prescribe for anxiety or depression symptoms in the epilepsy clinic. Care models involving neurologist prescribing for anxiety and depression symptoms merit further investigation and potential adoption in clinical practice.

A systematic review of the effects of character strengths-based intervention on the psychological well-being of patients suffering from chronic illnesses

AIMS

To identify and evaluate the available evidence on the effectiveness of character strengths-based intervention on the psychological well-being of patients with chronic illnesses.

DESIGN

A systematic review with meta-analysis.

DATA SOURCES

Six electronic databases, including PubMed, EMBASE, EBSCO (CINAHL^® and MEDLINE), Web of Science, and PsycINFO, were searched from inception to December 2018.

REVIEW METHODS

The quality appraisal of evidence and summary of studies were undertaken following Joanna Briggs Institute critical appraisal checklists and the standard guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Meta-analysis was conducted according to Cochrane methods using RevMan 5.1.

RESULTS

Clinical studies on the character strengths-based intervention for patients with chronic illnesses are limited. Eight studies involving 692 patients were identified and critically appraised in this review. Meta-analysis results for three comparable studies indicated that character strengths-based intervention was effective in improving the self-esteem of patients with chronic illnesses and it significantly enhanced their general self-efficacy and reduced their depression.

CONCLUSIONS

The findings support the effectiveness of character strengths-based intervention on improving the psychological well-being of patients with chronic illnesses. However, caution is needed in interpreting these results due to limited studies and heterogeneity across studies. Further research is needed to provide strong evidence on the applicability of the intervention in clinical practice.

IMPACT

This rigorous review provided current evidence on using character strengths-based intervention to improve the psychological well-being of patients with chronic illnesses. Character strengths-based intervention provides a creative approach for patients because it may help improve their well-being, happiness, self-esteem, and self-efficacy, and reduce depression and mental symptoms. Studies in different groups of patients suffering from chronic illnesses are recommended in the future. The character strengths-based intervention should be replicated in various inpatient facilities and include a larger and a more ethnically and socioeconomically diverse sample.

Photic sneeze reflex: another variant of the trigeminocardiac reflex?

The photic sneeze reflex (PSR) is a condition of uncontrollable sneezing episodes in response to bright light. This reflex often manifests as a mild phenomenon but may cause devastating consequences in some situations (aeroplane pilots, car drivers, etc.). Its exact mechanism is poorly understood. Interestingly, the roles of the fifth and tenth cranial nerves, brainstem nuclei and inciting patterns closely mimic a well-known brainstem reflex, known as the trigeminocardiac reflex (TCR). In this critical review, we hypothesize that the PSR can be a variant of the TCR. This concept will lead to a better understanding of the PSR and sharpens the TCR characteristics and open the doors for new research possibilities.
