What goes on at the neurobiological level that makes someone more vulnerable to self-injure or self-harm? What biological risk factors are at play? What roles do the vagus nerve, cortisol levels, and hypothalamic-pituitary-adrenal (HPA) axis have? We hope to discuss the psychology of self-injury pain in a future episode, but in this episode, Dr. Michael Kaess from the University of Bern in Switzerland explains the neurobiology of self-injury in simple terms, or what we hope can be considered simple layman's terms.

Learn more about Dr. Kaess and his research team at the Universitäre Psychiatrische Dienste (UPD) in Bern here.

How are scars from nonsuicidal self-injury (NSSI) different than physical scars that are unintentional or result from non-self-inflicted wounds ? What psychological effects can result from daily reminders of one's own decision to self-harm? Is there an association between NSSI scars and suicidal thoughts and behaviors? In this episode, Dr. Burke discusses the mixed relationship that many people who self-injure have with the scars they bear from NSSI and how some may feel the need to hide their scars even from themselves.

The term "self-harm" is an umbrella term, encompassing a broad range of behaviors, under which is included substance abuse and misuse, suicide, nonsuicidal self-injury (NSSI), and even eating disorders. In this episode, Dr. Katie Gordon, a Licensed Clinical Psychologist in Fargo, North Dakota, discusses the prevalence of self-injury among individuals with eating disorders and the prevalence of eating disorders among those who self-injure. She explains the relationship between the two behaviors, including common risk factors.
