Suicide and Epilepsy

Social support and the burden of physical and psychiatric comorbidities in the patients with late-onset epilepsy in China: A cross-sectional study

INTRODUCTION

Epilepsy is the third most common neurological disorder in elderly people. Patients with epilepsy (PWEs) are more likely to have comorbidities. Social support is very important for PWEs. However, there are many gaps in the research on social support in older PWEs, especially the correlation between social support and comorbidities.

METHODS

A cross-sectional study was conducted in three hospitals in China. Social support was assessed using the Social Support Rate Scale. The burden of physical comorbidities was assessed using the CCI, and global disability was assessed using the mRS. The NDDIE was used to assess depression, the GAD7 was used for anxiety, the CDR was used for cognitive status, and the NPI was used for psychotic symptoms.

RESULTS

A total of 154 older PWEs participated in the study. There were 97 patients with at least one physical comorbidities. The burden of physical comorbidities was negatively correlated with overall social support (Adj. r = -0.35, P < 0.001) and global disability (Adj. r = -0.45, P < 0.001). In terms of psychiatric comorbidities, anxiety, depression, and cognitive status were not correlated with overall social support (Adj. r = -0.03, -0.02, and -0.11, P > 0.05). Psychotic symptoms were correlated with overall social support (Adj. r = -0.20, P < 0.05). The overall burden of psychiatric comorbidities was associated with overall social support (r = 0.30, P < 0.01).

DISCUSSION

Neurologists and social workers should consider more personalized biopsychosocial care to improve the quality of life of older PWEs.

Death from exsanguination due to power drill injuries in a complex suicide: a case report

We present a case of a complex suicide of a 66-year-old man with a history of several psychiatric disorders. He attempted to commit suicide by inflicting cut wounds on his forearms, wrists, and neck but afterwards changed the method of suicide by using an electric power drill. After several unsuccessful attempts to drill a hole in either his head, thorax, or abdomen, he managed to perforate the common carotid artery on the right side of his neck and subsequently died from exsanguination.

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.

Factors related to the severity of obsessive-compulsive symptoms and their impact on suicide risk in epileptic patients

OBJECTIVE

To explore relevant factors for the severity of obsessive-compulsive symptoms (OCSs) in adult epileptic patients and investigate whether the severity of OCSs is a mediator in the relationship between depressive/anxiety symptoms and suicide risk in epileptic patients.

METHODS

This was a cross-sectional study from a hospital in Northeast China. Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Neurological Disorders Depression Inventory for Epilepsy (NDDIE), Generalized Anxiety Disorder (GAD-7), and Nurses' Global Assessment of Suicide Risk (NGASR) were used to assess the severity of OCSs, depressive symptoms, anxiety symptoms, and suicide risk in epileptic patients, respectively. The independent factors of the severity of OCSs and their mediating effects in the relationship between depressive/anxiety symptoms and suicide risk were evaluated by regression analyses and mediator models, respectively.

RESULTS

NDDIE scores (β = 0.404, p < 0.001), GAD-7 scores (β = 0.247, p = 0.009), and polytherapy (β = 0.119, p = 0.032) were the independent factors of Y-BOCS scores. The Y-BOCS scores partially mediated the relationship between GAD-7 scores and NGASR scores (standardized coefficients of indirect effect = 0.109, Bootstrap 95% CI = 0.024 to 0.214). Still, they did not mediate the relationship between NDDIE scores and NGASR scores (standardized coefficients of indirect effect = 0.062, Bootstrap 95% CI = -0.024 to 0.169).

CONCLUSIONS

Depressive symptoms, anxiety symptoms, and polytherapy are independently associated with the severity of OCSs in epileptic patients. Depressive and anxiety symptoms mediate the effect of the severity of OCSs on suicide risk in epileptic patients completely.
