Diagnosis of Epilepsy by Traditional Healers and Its Implications on Management in the Selected Rural Communities of Limpopo and Mpumalanga Provinces: A Qualitative Study

Introduction

Epilepsy is a neurological disorder which causes seizures and may be accompanied by loss of unconsciousness and control of bowel or bladder function. However, other types of epilepsy are only characterised by rapid blinking or a few seconds of staring into space. Many people living with epilepsy in rural communities consult traditional healers as their first line of treatment for epilepsy. Second preference is given to medical practitioners which causes unnecessary delay in the early diagnosis and treatment of epilepsy. This study aimed to explore how traditional healers diagnose epilepsy and its implications on management in the selected rural communities of Limpopo and Mpumalanga Provinces.

Methods

A qualitative approach using explorative, descriptive and contextual designs was adopted. Purposive sampling was used to sample six villages in Limpopo and Mpumalanga Provinces. Snowball sampling was used to sample twenty traditional healers. Data were collected through in-depth individual interviews at the participant's homes. Data were analysed using Tesch's eight steps of open coding data analysis.

Results

This study found that traditional healers have varied beliefs and misconceptions regarding the causes and diagnosis of epilepsy, hence this greatly influencing the management. The misconceptions on the causes include a calling by ancestors, urine contents, snake in the stomach, contaminated digestive system and witchcraft. The management included using herbal plants, insects, foam excreted during seizures and urine of the person living with epilepsy.

Recommendation

It is recommended that for effective management of epilepsy, there should be coordination between traditional healing and western medicine. Future research should look at the integration of traditional medicine and western medicine.

Replacement of Valproic Acid with New Anti-Seizure Medications in Idiopathic Generalized Epilepsy

Background: Little is known regarding the non-inferiority of new anti-seizure medications (ASMs) in terms of replacing valproic acid (VPA) in patients with idiopathic generalized epilepsy (IGE). We hypothesized that replacement of VPA with new ASMs would offer non-inferior or better control of seizure frequency. The purpose of this study was to compare epileptic seizure frequency between the subset of patients with IGE who were on VPA and the subset of patients with IGE who replaced VPA with new ASMs. Methods: Patients with IGE who were on or had been on VPA between January 2016 and March 2022 were divided into a group that replaced VPA with new ASMs (VPA-replace group) and a group that remained on VPA (VPA-continue group). We then compared the groups in terms of seizure frequency and myoclonus. Results: Of the 606 patients on VPA between January 2016 and March 2022, 156 patients with IGE were enrolled to this study (VPA-replace group, n = 68; VPA-continue group, n = 88). The VPA-replace group included significantly more females than the VPA-continue group (p < 0.001). The VPA-replace group also showed significantly higher seizure frequency before replacement (p < 0.001), but not after replacement (p = 0.074). Patients on monotherapy displayed improved seizure frequency with new ASMs (p < 0.001). Among the new ASMs, perampanel (PER) significantly improved seizure frequency (p = 0.002). Forty-two patients in the VPA-replace group who had myoclonus achieved significant improvements (p < 0.001). Among these, patients on PER monotherapy (p < 0.001) or PER + lamotrigine (0.016) showed significantly improved myoclonus scale scores. Conclusions: This study shows the non-inferiority of new ASMs compared to VPA, with better seizure control using new ASMs in subsets of patients with IGE on monotherapy.

Activities of daily living are associated with outcomes of epilepsy treatment in elderly patients

AIM

Controlling epileptic seizures in elderly populations is widely considered to be relatively easy, but we hypothesized that the lifestyles of elderly individuals may affect the outcomes of epilepsy treatment. The purpose of this study was to review the activities of daily living (ADL) of elderly individuals with epilepsy and compare them with the outcomes of epilepsy treatment.

METHODS

Of the 177 patients ≥65 years old who were referred to our epilepsy centre, epilepsy was diagnosed in 84. ADL and treatment outcomes were then reviewed, with ADL classified into three levels: ADL I, without disability; ADL II, disabled only in some instrumental ADL; and ADL III, disabled in some basic ADL. Epilepsy syndromes and use of anti-seizure drugs were also evaluated.

RESULTS

Forty-five patients (53.6%) achieved freedom from seizures, 23 (27.4%) achieved ≥80% but <100% reduction in seizures, 5 (6%) achieved ≥50% but <80% reduction in seizures, and 11 (13.1%) achieved <50% reduction in seizures. Thirty-five patients (81.4%) with ADL I achieved freedom from seizures, compared with seven patients with ADL II (28.0%) and three patients with ADL III (19.0%). A significant difference was evident among the three groups (F = 6.145, P = 0.003).

CONCLUSIONS

ADL should be taken into account when an epilepsy treatment is being selected.

Prescription patterns of antiepileptic drugs in Kazakhstan in 2018: A retrospective study of 57,959 patients

AIM

The goal of this retrospective study was to analyze prescription patterns of antiepileptic drugs (AEDs) in Kazakhstan in 2018.

METHODS

This study used prescription data of patients with epilepsy who received AEDs in Kazakhstan in 2018. The outcome of the study was the prevalence of use of several AEDs (i.e., valproate, carbamazepine, lamotrigine, topiramate, levetiracetam) in these patients. Demographic variables included age and sex. The present study used descriptive statistics only.

RESULTS

In 2018, 57,959 patients with epilepsy with at least one AED prescription were found in the LRx database in Kazakhstan. The three most frequently prescribed AEDs were valproate (54.6%), carbamazepine (49.3%), and lamotrigine (16.8%). Interestingly, 10,745 valproate users were women aged ≤40 years. Monotherapy was more frequent than combination therapy and ranged from 80% in patients receiving topiramate to 90% in those receiving carbamazepine. The three most common combination therapies were valproate-carbamazepine (33.7%), valproate-lamotrigine (16.9%), and lamotrigine-carbamazepine (11.8%).

CONCLUSIONS

Patients with epilepsy were frequently prescribed valproate, carbamazepine, and lamotrigine in Kazakhstan in 2018. Further research is needed to gain a better understanding of the prescription of valproate in women with epilepsy who are of childbearing age.
