Newly unsealed court documents and forensic neuropsychological evaluations have provided the deepest insight yet into the mental health profile of Bryan Kohberger. Before entering a guilty plea for the November 2022 murders of four University of Idaho students, the 30-year-old former criminology doctoral candidate underwent extensive psychological testing that revealed multiple neurodevelopmental and psychiatric diagnoses.
Diagnoses and Social Interaction Deficits
The evaluations, conducted by defense-retained neuropsychologists, revealed that Kohberger was diagnosed with Level 1 Autism Spectrum Disorder, Obsessive-Compulsive Disorder (OCD), Attention-Deficit/Hyperactivity Disorder (ADHD), and Avoidant/Restrictive Food Intake Disorder (ARFID). Evaluators noted distinct behavioral traits during testing, including a flat affect, irregular speech cadence, a lack of descriptive hand gestures, and an awkward delivery of humor that severely impacted his ability to connect with peers. The Bryan Kohberger psych evaluation autism OCD ADHD mental health findings also detailed a chronic struggle with “visual snow” syndrome and depersonalization-derealization disorder dating back to his adolescence.
“Kohberger demonstrates substantive impairments in social cognition and nonverbal communication that date back to early childhood.” — Dr. Rachel Lawson Orr, Neuropsychologist Evaluation Report
While the psychological records detail Kohberger’s long-standing struggles with social isolation and neurodivergence, legal experts point out that these diagnoses do not absolve criminal liability under state law. Prosecutors emphasized that his meticulous planning and calculated actions surrounding the crimes demonstrated a clear consciousness of guilt.
