Concussion May Result in New-Onset Bipolar Disorder: A Case Report

Area of Science:

• Neurology
• Psychiatry
• Trauma Research

Background:

• Emotional dysregulation is a known consequence of concussion.
• The development of new major psychiatric disorders, like bipolar disorder (BPD), following concussion has not been extensively studied.
• BPD typically involves distinct depressive and manic episodes.

Observation:

• A 50-year-old male with pre-existing ADHD and OCD experienced a concussion from a motor vehicle collision.
• One year post-concussion, he was diagnosed with new-onset BPD, leading to severe medical complications including a hypertensive crisis, aortic dissection, and stroke.
• The patient later required involuntary admission for a suicide attempt, with persistent BPD symptoms.

Findings:

• This case presents a potential real-world example of the diathesis-stress model (DiSM) in the context of post-concussion BPD.
• The study highlights the link between head trauma and the emergence of severe psychiatric illness.
• Bipolar disorder onset following concussion can have profound and lasting health consequences.

Implications:

• Emphasizes the need for heightened awareness and early screening for psychiatric conditions in individuals with a history of concussion.
• Suggests that concussion may act as a significant stressor in the diathesis-stress model for developing BPD.
• Underscores the importance of comprehensive patient monitoring following head injuries, particularly in those with a history of psychiatric conditions or family history of BPD.
