Traumatic brain injury (TBI) is a medical condition that can affect one’s physical, neurological, and/ or emotional functioning. The Centers for Disease Control and Prevention (CDC) defines a traumatic brain injury as “a disruption in the normal function of the brain that can be caused by a bump, blow, or jolt to the head, or penetrating head injury.” The specific symptoms that develop because of a TBI will vary significantly, as they depend on the type of injury, the severity of the injury, as well as the area of the brain that was injured. The nature of the symptoms can shift as some TBI symptoms may appear immediately and dissipate rather quickly, while others could present several days or weeks later, and some experienced symptoms may evolve over time. 

Narcissistic Personality Disorder

Narcissistic personality disorder (NPD) is one of ten different types of personality disorders that are recognized in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). It is a chronic mental health condition that is characterized by a long-term pattern of exaggerated feelings of self-importance. The Mayo Clinic explains that individuals with a narcissistic personality disorder “have an inflated sense of their own importance, a deep need for excessive attention and admiration, troubled relationships, and a lack of empathy for others.” Most often beneath the grandiose façade, individuals diagnosed with narcissistic personality disorder are hiding and avoiding profound feelings of insecurity. An estimated 5% of the U.S population may have a narcissistic personality disorder, which means over 16 million people might experience the condition.

NPD and TBI

The Journal of Neurology, Psychiatry and Brain Research asserts “Chronic ailments are likely to lead to the emergence of narcissistic traits or a narcissistic personality style. Traumas (such as brain injuries) have been known to induce states of mind akin to full-blown personality disorders.” Psychiatric News discusses various published studies of all personality disorders with findings that indicate between 11% and nearly 13% of patients with TBI also demonstrate personality disorders, and of those, only about 0.61% appear to present with a narcissistic personality disorder. The answer to the question: Can a brain injury cause narcissistic personality disorder? If yes; there are cases that show that narcissistic personality disorder is caused by head trauma.
