The impact of one-year COVID-19 containment measures in patients with mesial temporal lobe epilepsy: A longitudinal survey-based study

The study of mental health status of people with epilepsy during the COVID-19 pandemic: A systematic review and meta-analysis study

INTRODUCTION

The COVID-19 pandemic has affected the lives of people with epilepsy (PWE) in various ways. This systematic review and meta-analysis aims to assess the mental health status and prevalence of mental disorders including depression, anxiety, stress, and psychological distress among PWE. Furthermore, this study evaluates changes in sleep patterns and presence of sleep disturbances among them. The findings of this systematic review can help health organizations, policymakers, and health workers to better prepare and respond to future health crises for PWE and other chronic disease patients.

METHOD

This systematic review was prepared using PRISMA reporting guidelines. We systematically searched PubMed, Web of Science, Scopus and Cochrane Library databases for studies that reported data on mental health parameters including depression, anxiety, stress, psychological distress, quality of life, and sleep quality, during the pandemic until May 2023. The analytical procedures were executed through the utilization of Comprehensive Meta-Analysis (CMA) software.

RESULTS

In our study, a total of 61 carefully selected studies were analyzed, yielding valuable insights into the prevalence and impact of various mental health indicators among PWE. The findings revealed that a significant proportion of PWE experienced distressing psychological symptoms, with depression being reported by 34% of participants. Additionally, anxiety was prevalent among 43% of individuals, while stress symptoms were reported by 49% of respondents. Moreover, a substantial portion of PWE, approximately 38%, reported experiencing poor sleep quality, further underscoring the multifaceted nature of the challenges faced by this population. These findings highlight the need for targeted interventions and comprehensive support systems to address the mental health concerns and sleep disturbances faced by individuals living with epilepsy.

CONCLUSION

The findings revealed that a substantial number of PWE experience symptoms of depression, anxiety, stress, and poor sleep quality. These results emphasize the importance of considering mental health and sleep assessments as integral components of care for individuals with epilepsy. The study underscores the need for further research and targeted interventions to address the mental health burden faced by this population. By prioritizing and addressing these challenges, healthcare providers can enhance the overall well-being and quality of life for individuals living with epilepsy.

Anhedonia in epilepsy

BACKGROUND

Anhedonia, the impaired ability to experience pleasure, is a core feature of major depressive disorder, one of the most common comorbidities in epilepsy. It is also reported as a clinical feature independent of depression in a number of other neurological conditions. This study aimed to establish the prevalence of anhedonia in a sample of people with epilepsy, with and without a diagnosis of depression, and to examine the clinical and demographic characteristics of those who present with this symptom.

METHODS

A consecutive sample of 211 people (118 female, 93 male, mean age 38.09 years) completed the Snaith-Hamilton Pleasure Scale (SHAPS) to determine the presence of anhedonia and the Hospital Anxiety and Depression Scale to determine levels of anxiety and depression. The majority of patients had focal epilepsy (n = 165), and the remaining patients had generalized epilepsy (n = 22), or unclassified epilepsy (n = 24). Sixteen percent of the sample had a clinical diagnosis of depression at the time of the study.

RESULTS

Over one in three of the sample (35%) reported significant anhedonia on the SHAPS. While these patients were more likely to have a diagnosis of depression (p < 0.01), 30% of people without a diagnosis of depression also reported significant anhedonia. Difficulties gaining pleasure on 12 of the 14 items on the SHAPS were associated with cognitive difficulties, with those reporting an inability to feel pleasure on the item scoring significantly lower on tests of cognitive function than those who were able to gain pleasure. Of the three cognitive domains examined (overall intellectual ability, verbal memory, and processing speed), a poor memory had the strongest relationship; with lower memory function associated with an impaired ability to experience pleasure on 9 of the 14 items.

CONCLUSION

While anhedonia is well recognized as a feature of depression, our data suggests that it can be present in up to a third of people with epilepsy who do not have a diagnosis of depression. Cognitive difficulties, particularly impaired memory function may mediate some features of anhedonia. The implications of these findings for the clinical management of anhedonia in people with epilepsy are discussed.
