What is the role of screening instruments in the management of psychiatric comorbidities in epilepsy? Tools and practical tips for the most common comorbidities: Depression and anxiety

Depression and anxiety are the most common psychiatric comorbidities in epilepsy and are known to increase healthcare utilization, the risk of refractory epilepsy, and anti-seizure medication intolerability. Despite this, depression and anxiety continue to be underrecognized and undertreated in people with epilepsy (PWE). Several barriers to the identification of depression and anxiety in PWE exist, including reliance on unstructured interviews rather than standardized, validated instruments. Moreover, there is a dearth of behavioral health providers to manage these comorbidities once identified. The use of validated screening instruments in epilepsy clinics can assist with both the identification of psychiatric symptoms and monitoring of treatment response by the epilepsy clinician for PWE with comorbid depression and/or anxiety. While screening instruments can identify psychiatric symptoms occurring within a specified time, they are not definitively diagnostic. Screeners can be time efficient tools to identify patients requiring further evaluation for diagnostic confirmation. This article reviews recent literature on the utility of depression and anxiety screening instruments in epilepsy care, including commonly used screening instruments, and provides solutions for potential barriers to clinical implementation. Validated depression and anxiety screening instruments can increase identification of depression and anxiety and guide epilepsy clinician management of these comorbidities which has the potential to positively impact patient care.

Listening to anxiety in persons with epilepsy. Development of an integrative assessment model based on qualitative interviews

OBJECTIVE

The differentiation and assessment of anxiety in persons with epilepsy is the subject of current research. There is no consensus on which forms of anxiety are epilepsy-specific, what pathological significance they have, and how they should be conceptually systematized. The aim of this study was to detect formal landmarks that organize and further distinguish the clinical multitude of epilepsy-related anxiety, thereby establishing a basis on which an integrative assessment of epilepsy-specific fears can be developed.

METHOD

Twenty-six patients with epilepsy-related fears were recruited for qualitative interviews at the Epilepsy Center of Freiburg in Germany. Prevalent types of anxiety included both periictal and interictal anxiety. Patients reported how living with epilepsy is associated with anxiety and to what extent. After an open interview, semi-structured questions were asked concerning epilepsy-specific anxiety, referring to established concepts and items. The contents of the interviews relating to anxiety were transcribed.

RESULTS

The reported fears associated with epilepsy reflect the individual "pathography" of each patient. The potentially anxiety-inducing events within this pathography include the first seizure(s), especially in cases involving the amygdalae; the process of diagnostic procedures; therapy, including side effects of antiseizure medication, surgery as a therapeutic option, or a difficult physician-patient relationship; and the further course of the disease, including the fear of disease progression with brain damage, cognitive deterioration, or professional and social disintegration. The integrative assessment model derived from the pathography of the interviewed patients thus reflects the dynamics and quality of epilepsy-specific fears, especially in relation to the healthcare system, without instantly pathologizing them. It highlights that anxiety, to a variable degree, is perceived as an adequate and comprehensible emotion and might be a problem long before the diagnosis is made in the case of ictal fear. Furthermore, anxiety symptoms may (re-)emerge, consolidate, modulate, diminish, or even aggravate during the course of the disease. The integrative assessment model maps crucial events inherent to the healthcare system that may become relevant as objects of prevention, intervention, and therapy.

CONCLUSION

The integrative assessment model can serve as a heuristic framework from which an integrative self-report questionnaire of epilepsy-specific anxiety might be designed. On the one hand, this would help to better understand the interrelation between epilepsy and anxiety in terms of their temporal occurrence and interdependence scientifically. On the other hand, it would allow for the enhancement of individual preventive and therapeutic measures for affected patients.
