Nonsuicidal self-injurious behavior in patients with and without epilepsy: a case-control study

Area of Science:

• Neuroscience
• Psychiatry
• Clinical Psychology

Background:

• Nonsuicidal self-injury (NSSI) is prevalent in persons with epilepsy (PWE), often linked to adverse outcomes like suicide attempts.
• No studies have directly compared PWE with NSSI to individuals with NSSI but without epilepsy.

Purpose of the Study:

• To investigate if PWE with NSSI represent a more severely affected subgroup.
• To compare clinical presentation and associated characteristics between PWE with NSSI and individuals with NSSI without epilepsy.

Main Methods:

• A case-control study compared 42 PWE with NSSI to 126 matched individuals with NSSI but no epilepsy.
• Participants underwent psychiatric evaluation and completed multiple validated questionnaires assessing self-injury, trauma, personality, depression, anxiety, and quality of life.

Main Results:

• The hypothesis that PWE with NSSI are more severely affected was not supported.
• Fewer risk factors like alcohol use, smoking, and piercings were noted in the PWE group.
• No significant differences were found in depression, anxiety, suicide risk, personality, or quality of life between groups.

Conclusions:

• Epilepsy is not associated with increased psychiatric severity or suicide risk in non-psychotic patients with NSSI.
• While sharing some risk factors, PWE with NSSI exhibit distinct characteristics compared to the general NSSI population.
• Emotional dysregulation in PWE may follow different pathways, influencing NSSI as a coping mechanism.
