Psychogenic Nonepileptic Seizures

Seizures in Namibia: A study of traditional health practitioners

OBJECTIVE

Countries in sub-Saharan Africa are plagued by poor healthcare facilities, lack of specialist care, and limited financial resources. People with seizures often rely on the help of traditional health practitioners (THPs). Traditional health practices are not acknowledged in Namibia and remain unregulated and open to exploitation. We conducted a qualitative study to gain an understanding of THPs' perceptions and experiences in delivering seizure care in Namibia.

METHODS

This study formed part of a larger mixed-method study that explored seizure care among healthcare providers (HCPs) in Namibia. Semi-structured interviews were conducted with 11 THPs in Namibia. Thematic analysis was used to identify themes and subthemes in the data. Themes were interpreted using the different levels of Bronfenbrenner's Ecological Systems Theory to illustrate the perceptions and experiences of THPs in the management of seizures.

RESULTS

THPs distinguish between seizures with physical causes and those caused by witchcraft, evil spirits, and supernatural forces. THPs acknowledge the role of Western medicine in the treatment of medically explained seizures (physical causes). Seizures as a result of medically unexplained symptoms (spiritual) are deemed best treated by traditional medicine (TM). Diagnostic and treatment practices are person-specific and are guided by divination and the use of plant and animal material. Treatment success is measured by the complete absence of seizures. Biomedical treatment is seen as lacking due to its focus on seizure control and failure to provide a permanent cure.

SIGNIFICANCE

In countries with limited healthcare resources, the untapped potential of THPs may play a valuable role in bridging the treatment gap for seizures. Incorporating THPs into the healthcare system depends on proper regulation and clear demarcation of roles between service providers. Improved referral practices and collaboration between service providers will be of benefit for people with seizures who are often exposed to stigma and discrimination.

Diagnostic and treatment practices for psychogenic nonepileptic and epileptic seizures in Namibia

PURPOSE

Information about existing healthcare resources for the management of seizures in developing countries is lacking. These countries are often poorly equipped to deal with the immense burden of costs, mortality, stigma, seizure-related disability, and comorbidities presented by seizure disorders. This study aimed to contribute to the goals of the International League Against Epilepsy (ILAE) by investigating the resources available for patients with seizure in Namibia.

METHODS

Two separate surveys on the diagnostic and treatment practices for epileptic seizures (ES) and psychogenic nonepileptic seizures (PNES) were administered to private healthcare practitioners (HCPs) in Namibia.

RESULTS

The findings are based on 50 responses from HCPs involved in the management of seizures. The responses indicate that HCPs have less confidence in their ability to manage PNES than ES. Psychological/psychiatric assessments are seldom utilized. Although HCPs engage in face-to-face communication of diagnoses, they seldom refer patients to additional sources of information. Healthcare practitioners follow up patients with ES more regularly than those with PNES. Healthcare practitioners indicated their willingness to collaborate and recognize the role of traditional health practitioners (THPs) in a supportive capacity when it comes to the management of seizures. Financial constraints, limited availability of specialized equipment, and lack of knowledge and awareness regarding seizure disorders among both HCPs and patients were mentioned as major obstacles in accessing healthcare services.

CONCLUSION

The findings of this study add to the current literature by demonstrating some of the particular characteristics of HCPs from a lower middle-income African country regarding the diagnosis and treatment of PNES and ES.

Video-electroencephalography investigation of ictal alterations of consciousness in epilepsy and nonepileptic attack disorder: practical considerations

The ictal assessment of consciousness is of central importance in the differential diagnosis of epilepsy and nonepileptic attack disorder (NEAD). Long-term video-electroencephalography (video-EEG) is currently considered the gold standard investigative technique for the evaluation of patients with recurrent attacks associated with transient alterations of arousal (responsiveness) and/or awareness (experiential states). This paper offers a concise review focusing on the practical aspects of clinical relevance in the video-EEG diagnostic workout of inpatients with suspected epilepsy or NEAD, as outlined in existing guidelines and recommendations. The reviewed literature implies that both implementation of specific procedures (e.g., activation maneuvers) and interpersonal approach (e.g., monitoring protocols) during video-EEG should be tailored to the individual patient's presentation.

[Drug-resistant epilepsy]

BACKGROUND

Despite the introduction of many new antiepileptic drugs during recent years, about one third of the epilepsy population continue to have drug-resistant seizures. We present two hypotheses on mechanisms of drug-resistant epileptic seizures.

MATERIAL AND METHODS

The article is based on our own clinical experience and literature identified through a PubMed search using the words: refractory, intractable, pharmacoresistant, drug resistant epilepsy/seizures.

RESULTS

There is no international consensus on the definition of drug-resistant epilepsy. Some epilepsy types appear to respond to drug treatment, while others are more resistant. Animal models and refractory patients have been studied to find mechanisms that can explain the lack of drug response in some types of epilepsy. Currently, two main hypotheses prevail. The transporter hypothesis implies an over-expression of the proteins (e.g. P-glycoprotein) capable of transporting drugs out of the epileptic focus. The target hypothesis implies changes in receptors or ion channels in the epileptic cellular network, which render this area less susceptible to antiepileptic drugs.

INTERPRETATION

Both hypotheses have weaknesses, and alternative theories have been presented. Much remains before the causes of drug-resistant epilepsy are understood. If patients do not achieve seizure control after having tried 2-3 antiepileptic drugs, they should be referred to the national epilepsy centre for a renewed diagnostic evaluation and for consideration of non-pharmacological treatment.
